Procedures

Add Disk To Existing RAID Volume

This can be achieved purely through the web interface...

  1. Insert new disk
  2. Format the disk through Disk Management > Volume Management (takes 30 mins or so for a 1.5TB drive in a TS-410)
  3. Expand the RAID volume through Disk Management > RAID Management (takes around 4 days to expand 3 -> 4 x1.5TB drives on a TS-410)

...but it is painfully slow, and for safety its recommended that you limit IO through your device whilst its in progress.

Check out the forum, there's a quicker command line method, which takes your device offline whilst the expansion takes place.

Troubleshooting

Unable to Boot

Assuming the device is completely inaccessible (either via the web GUI or SSH), try the following...

  1. Remove all disks
  2. Restart the system
  3. After a while detect the system using QNAP Finder (it'll have lost its config so will need to obtain a DHCP address)

Upgrade Unbootable Device

  1. Obtain the latest firmware image, use the following URL's as a guide, and work out the current version from http://www.qnap.com/download.asp...
  2. Power of the NAS
  3. Remove all the HDDs
  4. Power on the NAS
  5. After a short beep and a long beep(about two minutes after first short beep), run the QNAP Finder(Make sure the Finder is the latest version).
  6. QNAP Finder should find the NAS and its IP
  7. Select the NAS and click Tools -> Update Firmware
  8. Input default username and password (admin/admin)
  9. Follow the page to select the firmware file (the flash image file which is about 13MB to 14MB).
  10. After firmware update, the NAS will be reboot.
  11. Make sure the firmware have been updated
  12. Power off the NAS
  13. Plug all the HDD back
  14. After power on, Update the firmware again using the update image on QNAP download site( which is about 90MB to 100MB).

Disk Read/Write Error

Logs report errors such as...

  • [RAID5 Disk Volume: Drive 1 2 3 4] RAID device in degraded mode.
  • [RAID5 Disk Volume: Drive 1 2 3 4] Drive 4 removed.
  • Drive 4 plugged out.
  • [RAID5 Disk Volume: Drive 1 2 3 4] Drive 4 failed.
  • [RAID5 Disk Volume: Drive 1 2 3 4] RAID device in degraded mode.

This can mean a failed drive, however it can occur as a false error, whereby the disk fails to respond as quickly as the NAS expects. Search Google for similar errors for your specific disk model to ascertain if its likely to be a recoverable problem.

To recover...

  1. Go to Disk Management | RAID Management
    1. Affected RAID volume will be showing In degraded mode
  2. Go to Disk Management | Volume Management
  3. If disk status is No Disk, i.e. its missing
    1. Pull disk out
    2. Give it 10 secs
    3. Put disk back in
  4. Browse away and back to Disk Management | Volume Management if required to refresh the page
  5. Disk will likely show Disk Read/Write Error
  6. Click Scan Now
  7. Disk status will change to Bad blocks scanning:(0%)
