Unable to Hot-Swap a drive in a Synology NAS
Posted on 2013-01-26
I have a Synolofy DS412+ NAS. Setup to use RAID1 (not SHR), 2 x 3Tb Drives seen as 1 volume.
All the coumentaion saya I should be able to Hot-Swap any drive.
Each time I try to hot-swap a drive, the drive put into the NAS is seen as degrade and I am expected to manually use OS software of NAS to repair the drive (takes about 10 hours).
It soen't seem to matter if the drive is blank or one that had previously been used in the NAS.
I do not lose any data as the drive that remains in the NAS is still accessable and retains all data.
I don't have a problem with the NAS taking x Hours to reconfigure , prep and mirror rhe data to the replacement drive. What annoys me is that I have to manually tell it to repair the drive. I though the NAS was supposed to do it automatically.
The idea was to take a disk off-site (for security) at regular intervals.
Any suggestion that can help.
