Question about Dell PowerEdge 2500 Server

1 Answer

Lack of space on C drive

I have a RAID5 system. My problem is some years ago i've defined the C drive with only 4GB (where i have OS W2000svr, anti virus server, backup software, and a few minor things), and now with the Microsoft Updates i don't have enough space. This situation is as follow:
C drive capacity 4 GB - free 50 MB
D drive capacity 63 GB - free 15 GB
I already run cleanup drive, and delete as much i could.
How can i "move" free space to drive C, or rebuild the virtual drives without re-installing everything ? (if possible)
Thank You. Luís

    Thank You.

    I've tried some of the mentioned points, and i could get a few more MB (now i have 100 Mb), but i will have the same problem in a couple of days.

    A question: Is there any way to rebuild the partition with the available space ? 15 GB ? Could i create a new partition (Z:), copy all what i have in the C: drive, switch the map letters and boot ? Perhaps, i could get in troubles, but if someone tried something similar.... we never know.

    Thank You,

    Thank You pasha, for your words. I still have doubts on wich strategie to choose, however test the "thing" on another machine must be a plus. What you mean by "Creating Ghost backups periodically becomes the bare metal recovery strategy for this server" ?

    Thank's,

You can relocate any my documents folders to the D:\ drive using a right mouse click and properties to enter a new directory. When you are logged onto the appropriate account.

If you have items on the desktop (data) you can relocate them to a folder on the D:\ drive and place a shortcut to them on the desktop -- same functionality but the disk usage changes drives.

You can uninstall specific applications and reinstall them on the D:\ drive

You may be able to reassign the temporary internet folders depending on the version of Internet Explorer to the D:\ drive to reduce use of C:\ Likewise Temp if you change the JCW value.

If you are using older versions of Internet Explorer that have been updated you may be able to remove backups using the add/remove programs scenario -- do not backoff current versions there are buttons in some versions of IE to remove the backups created when updating.

Using add/remove programs to eliminate items not used. If this is a true server -- items like calculator and numerous accessories could be removed. There may be additional unused programs and services that can be removed to buy some additional space.

Anti-Virus software often keeps backup copies of signature files -- reviewing your software in that area could provide additional files that could safely be removed.

I do not know if windows 2000 had the indexing service. If it does is maintains a second directory and space of the search service is not required eliminating the associated data can reduce C:\ drive space requirements -- if necessary the associated files can be relocated to the D:\ drive.

In the end all of the above may not be much space but it could be some.

    The issue depends on the capabilties of the raid in part to resize partitions. Another possibility may be the addition of a drive to the machine. Copying the C: drive to the new drive could address storage issues. It might also improve performance -- the system on a separate physical drive from the data. However timing and the boot process would need to be considered. One method to achieve this would be to ghost (A Symantec/Norton product) off a backup of the C:\ drive to CD ROM or DVD whatever is available, then install a new drive and ghost into a larger partition on the new drive the backed up C:\ drive. As the C:\ drive is no longer raid protected Creating Ghost backups periodically becomes the bare metal recovery strategy for this server, in case of a drive failure or worse. This method offers safety in that the current C:\ partition remains intact until after the new drive is in place and tested. The backup could be avoided if Ghost can be used in your environment to copy the existing C:\ to the new drive directly which may also be possible (assuming the raid driver/data can be reached without booting the Windows 2000 Operating system). However this does not verify a bare metal backup and restore process works as identified above. The other route kills two birds with one process.

    I have also successfully used a program called Partition Commander against standard disk drives but never a raid 5 set of disks. Unless you have documentation supporting this I would seriously recommend against attempting this solution on a live server.



    Riskier than the above solution using Ghost is to utilize ghost to facilitate reallocation the existing partitions on the server. As this requires the destruction of both partitions and the restoration of both partitions you will be at the mercy of your backup procedures once you delete and reallocate the disk partitions. Assuming your situation is average, you have probably never restored your system from bare metal and may not have a working solution that does not involve building the OS and installing the backup application before being able to restore the server. And then does the solution permit resizing of the partitions during the restore. So the following will attempt to discuss such a backup and restore scenario however unless you have a backup server around doing nothing with suitable disk space to test on this process has all the risks of a live test with all the consequences.



    Review your existing backup process and assure it backs up files and not image copies of the disks. To be able to resize a partition we need to be able to restore files and not entire disks or blocks of disk space above the file level to the data partition (D:/) of your drive. Assure all data and programs to perform a restore are on the C:\ drive and/or are accessible from the backup media -- assure backup directories or files or other restore information is not on the D:\ drive we intend to restore using the existing backup that will not be available as the partition has either be reallocated or we are operating on new disks.



    Consider doing this with additional disks available to swap in the server protecting the original system until the new server is functional.



    To avoid the need to rebuild the OS and install the backup program and then overlay portions of that from your backup medium possibly encountering locked file issues. Again as before use Ghost booted from the CD to backup the C:\ drive (still assumes the raid 5 is accessible from a booted CD).

    If at all possible restore this to another machine or different disks for safety just to make sure it works and the media is readable. Then with the OS back in place we should be able to boot the machine using the restored C:\ and restore the new D:\ partition from the current backups using the backup application (that should only require the c:\ drive and the backup media if we checked properly before).



    I have done these kinds of moves before. If you cannot tell I get nervous between the time I have destroyed a working system until it works again. I believe you cannot be too careful in protecting the data and the system when considering a significant operation on a live server. Having the existing drives on the workbench ready to install if something fails allows you a very secure feeling. Without that depending on the value of the server and data I imagine you may become nervous too.

  • david Jan 03, 2008

    A bare metal recovery strategy is the strategy required when the server must be replaced with an entirely new server or the disks in the server must be replaced by new disks and the contents of the old server or disks are unavailable to support the process. (The server or drives were damanged to such an extent that they are unusable.) In other words, your backups and installation media and configuration documentation are the only sources for recovery of the server.

Need advise on slow running Mavericks?


Did you check hard drive space? You drive may be running out of much needed free spaces. You can check by About This Mac through Apple Logo. Also I would recommend to run Disk Utility Verify/Repair disk in order to fix any error on the drive. You should download Stellar Speedup Mac software to clean & optimise Mac hard drive for free. You can remove plenty of junk data from the startup drive. You can download from here - Stellar SpeedUp Mac
Try to keep at least 25% of hard drive free for OS X operations.

Drive C shows low disc space but is only half full


This could be caused by a virus, or you could simply have a small HDD with a newer version of your OS. Certainly I recommend running a full scan with the free version of Ad-Aware Anti-Virus from Ad Aware Free Antivirus and Antispyware by Lavasoft Protection from... to start with. Also, if you have a smaller hard drive, something around 40GB or less, newer versions of the Windows OS will not consider the percentage of the drive's storage space in use, but only the raw amount of free space available on said drive.

Another possibility involves the paging file and its size, something which would be a concern on any modern OS. If your paging file, or virtual memory allocation, is too large, you can receive warnings about low disk space because even when it is not in use that storage space is counted as "in use" by your OS.

Finally, in general these types of problems can result from not performing routine maintenance on your HDD and its partition(s) and file system(s). Running a file-system integrity scan and a thorough defragmentation operation on your drive is a good idea just on principle alone.

1. Can Windows access memory above 4GB?

a. 32-bit - NO

b. 64-bit - Maybe (due to chipset limitations)

2. Can your processor access memory above 4GB?

a. If it's recent then it might, and if it's either AMD64 or EM64T it's almost certain

3. Does your chipset allow pages to be remapped above 4GB?

a. Probably not - and that's what's catching people who install 64-bit Vista to work around point 1 - they find they still cannot see above 4GB

In some cases, OEMs may be able to tweak their BIOS to reserve less memory for platform use, but we're not talking a huge difference (ie, 100's of MBs).

In the end a 32-bit OS and/or application can only, ever, handle 4GB of memory at a time, the AWE stuff just swaps chunks of memory in and out of that 4GB space, thus fooling the application and OS into using more space than it can "see".

Physical Address Extension (PAE), extends the physical address space to 36-bits if your HW supports this. For most operations, the processor execution units will only see 32-bit addresses, the MMU will take care of the translation to 36bit addresses. No swapping here, only page translations (which are used regardless of PAE being on or not), this is a fundamental feature of any virtual memory operating system.

The OS and apps only see 32-bit addresses because the registers are limited to 32-bits (hence the "32-bit" architecture nomenclature). These are linear addresses which are extended to 36-bits in the translation to physical addresses, but they never show up in registers since there's no room. It's all internal until the address lines coming out of the chip are toggled. Thus my comment above about "if your H/W supports this (PAE)". I'm not going into how that works...

So, the OS can happily handle up to 64 GB of memory for 32-bit PAE-able systems.

Hope this helps explain the whole, 'Why can't I see 4 Gig of RAM in my system?" thing...

BTW - This does not change for Vista either...

there is an overhead for the space on a drive, the system needs a File Allocation Table and other administrative information, so the total 4 GB is usually not 100% available. It would not work properly without this "administrative" space.

Error message if trying to save files larger than about 4GB.


The Buffalo Ministation hard drive comes with a default FAT32 file system. This file system is used for compatibility with Windows, MAC OS X, LINUX, etc. The file system does not allow files to exceed 4GB. To save larger files, the disc must be reformatted. For Windows, it should be reformatted to NTFS.

Hi j0shuatsb,
Acer like many other manufactures seem to design their system to fail or have issues just after their 1 year warranty is up. Like other Microsoft windows operating systems, when you receive an error message that you're memory is full. This does not mean you have run out of RAM = memory. You're notebook can only run a max of 4GB of memory. The error message refers to hard disk drive space. Depending on you're operating system, windows will lock out so much drive space so it can move about. All notebooks also have a hidden partition which holds drivers & programs used in combination for running the system restore.
This hidden partition can range in size from 2GB up to 4GB.
This also lessens you're total hard disk drive space. Bottom line is there is nothing wrong with your memory.
What you need is a larger hard disk drive. Notice the Technical specifications from this link:
http://www.acer.co.uk/public/page9.do?sp=page4&dau34.oid=24360&UserCtxParam=0&GroupCtxParam=0&dctx1=17&CountryISOCtxParam=UK&LanguageISOCtxParam=en&ctx3=-1&ctx4=United+Kingdom&crc=512458878
It does not show what size you're SATA hard disk drive is.
Since you are still in warranty, now would be the time to increase you're drive size. On another note, if you're HDD is the standard 160GB than there is an issue with your current HDD.
Please run a full system virus scan.
Suggest you back up all you're personal data on to a DVD & run you're system restore CD including a format to help you regain you're HDD full space. A temporary fix would be to uninstall any non needed programs through Add/Remove programs. This should free up some space. Many Acer programs you do not use at all or need should be the first to go.

Cannot see 4 gb ram


Hi Ciccio8670,

If you are running 32-bit Windows, you must live with it. You will not ever see all 4GB of RAM you've paid for.
If you are running 64-bit Windows, you may have to live with it. Depending on your motherboard's chipset, your system may support memory remapping. If so, you will be able to use all 4GB of RAM.

Detailed:
Due to an architectural decision made long ago, if you have 4GB of physical RAM installed, Windows is only able to report a portion of the physical 4GB of RAM (ranges from ~2.75GB to 3.5GB depending on the devices installed, motherboard's chipset & BIOS). This behavior is due to "memory mapped IO reservations". Those reservations overlay the physical address space and mask out those physical addresses so that they cannot be used for working memory. This is independent of the OS running on the machine. Significant chunks of address space below 4GB (the highest address accessible via 32-bit) get reserved for use by system hardware: • BIOS – including ACPI and legacy video support • PCI bus including bridges etc. • PCI Express support will reserve at least 256MB, up to 768MB depending on graphics card installed memory
What this means is a typical system may see between ~256MB and 1GB of address space below 4GB reserved for hardware use that the OS cannot access. Intel chipset specs are pretty good at explaining what address ranges gets reserved by default and in some cases call out that 1.5GB is always reserved and thus inaccessible to Windows.
