ReadyNAS 2312 -- how to replace a disk that's still working, but the Volume is shown as "degraded"?
Hi,
we have a ReadyNAS 2312 with 6 disks installed.
The volume data has been continuously shown to be "degraded" for quite some time and does not seem to get fixed over time.
One of the disks shows a lot of "ATA errors", but is still working and is still in use by the NAS, we think this might be the reason for the "degraded" messages.
I'm not sure, how I can replace the disk in this situation (for example additionally install a new disk and tell the NAS that the malfunctioning disk is supposed to be phased out) without losing my data.
Can anyone help?
Thanks in advance!
"Degraded" means a bad drive has caused you to lose redundancy. The "Volumes" tab in the GUI should show you which one that is (will be some color other than blue). Hopefully, it's the one with the ATA errors. Otherwise, that one may fail as the system tries to re-sync the replacement for the other. Regardless, you should insure your backup is up to date before you proceed any further.
Drive replacement is done by removing the bad drive and inserting the replacement with power on. XRAID will take care of everything form there. Don't try adding to another slot with the bad one still installed, as it may think you want to expand with that drive, not use it as a replacement.
