Question about Synology Disk Station DS207+ (DS207PLUS) Network Storage Server

1 Answer

Repeated hard disk failure and slow internal webserver

I've had this product for about 3 months. During that time the second hard disk has failed twice and been replaced with a brand new unit. My third hard disk failed this week - it was Western Digital rather than Seagate, and I have little confidence in the unit. Is this likely to be a fault with the Disk Station itself or is there anything else I can do apart from return for warranty replacement.

I've also found the unit to be incredibly slow when running as a webserver, taking over 15 seconds to generate a webpage using PHP and SQL compared with 2-3 seconds on my own PC's builtin webserver.

Functionality of the unit and associated software appears to be excellent apart from these two critical problems.

Hi,

I have a simular problem with my DS207+. My second (sic!) volume failed especially when copying a lot.
But as I was using RAID1, I just repaired it and lived with it for the next months.
But now I want to have "Basic" drives.

I found this:

I will try and get hold of those cables.

If your third disk is failing again, it seems like a cable issue as well.

regards,
Markus

How to format


To format a hard drive or array, select it from
the Target Disk drop box. Choose the file
system desired from the File System dropbox
(internal drives can only be formatted with XFS).
Note that FAT32 has a 4 gigabyte filesize limit
for individual files. If you choose FAT32 for your
file system, you will not be able to store single
files larger than 4 gigabytes on the drive. Use of
the XFS or EXT3 file systems is recommended.
Press Select Target Disk when done, and then
Start format.
Depending on the size of the target hard disk or
array, a disk format may take several hours to
complete. Shares on the LinkStation will not be
accessible during the disk format.
Note: Reformatting a drive will erase all data
on it! Back up any data on the drive before
reformatting it.

Implementing RAID 1 in Windows Server 2003 using VMware!


This is a simple tutorial about creating a RAID 1 in VMware for IT people. VMware, well I think you know already about Server Virtualization.Its a well known product.
Let's discuss about some of the techniques related to Load Balancing or Fault Tolerance.....The Disks here used are Dynamic Disks.
RAID - Reduddant Array of Independant (Not much Inexpensive these days. That term suites no more) Disks. There are two types of RAID:
  1. Software RAID - Implemented via the OS or with the help of a Software. Not much efficient however.
  2. Hardware RAID - Hardware level RAID. Much more efficient and Fault Tolerant.

The idea to use a set of disks or an array is to increase the performance (Load balancing) and provide Disaster Recovery (Folt Tollerant).
RAID 0 - StripingThe fastes of all the RAID configurations. This is known as Striping. Striping is the process of Writing data Sequentially to or Read from more than a single Hard Drive (or a Storage Device).First the data is broken up into chunks or blocks. Then the writing process will be accomplished. The process of writing will be done Simultaneosly onto Strips. The performance of reading and writing increases because all the Heads are working all the time
RAID 1 - Mirroring,DuplexingAs the name implies, it creates a Mirror of one Disk onto another. Data will be written to Both the Disks. So if one disk fails other one can be mounted or it can be used to Restore data.There can be a deadlock how ever. The Disk Controller. RAID 1 uses a Single Disk Controller thus a Single point of failure.We can avoid this easilly with the use of Disk Duplexing which means usage of 2 Disk Controllers.
RAID 2 - Striping with ParityThis is similar to RAID1 but with an added feature known as Parity. One disk - typically the last one - is used to store somethings called Parity bits. With the use of these Parity Bits, the lost data can be easilly generated. This uses Logical XOR Operation. When writing, it XORs every data written onto HDDs and stores in the Parity Disk. When one Disk fails, thet PD is XORed with other Data bits on the functioning Hard Drives. This is a very effective technology in terms of Fault Tolerance. But Performance is pretty low.
RAID 3Similar to RAID 2 but instead of using Strips which are in Bits this technique uses Strips in Bytes. That increases the performance over RAID2.
RAID 4Strips data (Blocks) and uses a Parity Disk. Requires at least 3 Drives. Not widely used.
RAID 5The most popular method. Requires at least 3 Disks. Disks are used to store Parity data as well for each perticular drive. Data Stiped in Bytes (uses block-level striping with parity). Supports Unlimited number of Drives. Failure rate Drops when the number of devices increas.High speed reads can be performed. But writing is pretty slow in this approach.
Note: The non-standard RAID levels 5E, 5EE and 6E extend RAID 5 and 6 with hot-spare drives. Other non-standard RAID levels include: RAID 1.5, RAID 7, RAID-DP, RAID S or parity RAID, Matrix RAID, RAID-K, RAID-Z, RAIDn, Linux MD RAID 10, IBM ServeRAID 1E, unRAID, and Drobo BeyondRAID.
So how are we going to implement such a structure in VMware?That is quite easy. This is an example of Disk Mirroring. Each disk has to have Similar Capacity.
  1. Click on "Edit Virtual Machine Settings".
  2. Click on Add ->Next-> Create new Hard Disk.
  3. Select SCSi.
  4. Give a Suitable Disk Capacity for new Disk.
  5. Give a "Name" and Browse the storage location.
  6. Click on Finish.
  7. You have to Repeat the steps to create the number of Disks that you require. You have to have 2 Disks. Do not use the Main Drive. Use Separate Disks.
  8. Click on OK.
  9. Click on "Power on this Virtual Machine".
  10. After booting up the machine, its the time to implement the Mirrors.
  11. Log in.
  12. Right click on My Computer and select "Manage".
  13. Click on "Disk Management".
  14. Get the "Convert Disk Wizard".
  15. Select the 2 disks (tick on the check boxes).
  16. Click "Next -> Finish
  • Implementing RAID1
  1. Right click on the Disk n which your first added drive (n = the number).
  2. Select "New Volume".
  3. Select the option "Mirrored".
  4. Click on "Next".
  5. Add the Disks from the left hand list box to the right hand list box (the two drives that you have created).
  6. Click on "Next".
  7. Assign a Drive Letter.
  8. Format using NTFS. Make sure you provide a "Volume Label".
  9. That's all what you need to do!
  10. Wait until the Volumes get formatted and Synchronize.
  11. Implementation of the other technologies are similar to the above procedure.
Hope you would enjoy this tutorial.Thanks!

Hello,I Have big problem, every day Between 13:00 & 14:00 clock the device become very slow please if you know solutions tell me ?? i am waiting ,, Regards.


Make sure that your anti-virus is not performing a scheduled exam during those times.

Your system will slow down because your anti-virus might be performing a scan during those times.


Hope this helps.

If the failed hard disk drive is replaced with the exact same capacity, RPM and make of hard drive, then the array can be rebuilt. Raid 0 cannot be rebuilt as each drive contains half of the data, If RAID 1 then can be rebuilt as data on each drive is an exact copy. However if combination of RAID 0 and RAID 1 then can be rebuilt. It's best really to handel this hands on, I recommend taking it to a computer technician especially if the information on it is important.

Thanking you

I lost connection to my Iomega 500gb network hard drive. I tried to reboot it but the drive's blue light keeps flashing after power up.


In that case you have a bad connection caused by a hardware failure. Take out the hard disk from the case, put it in a desktop and try to access directly there. If you can then the electronics of the case have failed - you need a new case.
If you can't then you need a new hard disk.

I keep losing the device every 30 seconds. the network is connected to a Gbps network


try changing the network cable, these are infamous having 16 points of failure in every cable. I find this especially true in my Gbps networks, crappy cables. Hope that helps! cheers. Next I'd look into your router/hub/switch. I have had many of these fail too after a couple years. Third, I'd try slowing my network to 100Mbps instead of auto in the network adapter properties under the speed heading. sometimes slowing it seems to solve lost packets. (which could be due to a bad wire) Hop that helps Also try simply moving the device closer to the router if its a wireless device, or change transmit channel on the router config, Noise can be introduced in a number of ways these days. cheers.

Fastora NAS-104WR


It all depends on how mission critical this NVR is, (and how much money you have to spend)


A good rule of thumb is the more redundancy the better, so in theory, if you have the money, you should buy the second NVR, however if you cant afford an entire second unit, you should look at doing hard drive backups of that unit.

If you have any more question, please let me know!

Thanks,
Mike

Freecom 160GB Hard drive not recognised


Drives do fail Nick. Is it powering up [power supply problem?] Plug it in and go to Start/Control Panel/Admin tools/computer management/storage/ removable storage and disk management. See if the disc is recognised there. If it is not, and if the disk is spinning Try putting it into the deep freeze overnight. Plugging in next morning and if it fires up get as much off as possible before it goes down again.
