=== Add Disk To Existing RAID Volume === | |||
This can be achieved purely through the web interface... | |||
# Insert new disk | |||
# Format the disk through '''Disk Management''' > '''Volume Management''' (takes 30 mins or so for a 1.5TB drive in a TS-410) | |||
# 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. | |||

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