RN1500 replace disk RAID5

[alisys]

Hi,

We have a ReadyNAS 1500 with RAIDiator 4.2.28 and 4x2TB in RAID5.

One disk failed and we have replaced it with an identical one (Seagate ST2000DL003-9VT166). The lights of the four discs flash green. But, that disk, in the web panel is still "inactive" and the RAID5 works degradated with only 3 discs.

The inserted disk is equal to the damaged one, without partitions and the chassis seems to recognize it but there is no feedback from the web panel. It's been more than 24 hours.

What can we do?


Thanks,

First check these settings, and change them (at least temporarily) as shown below

• Frontview > System > Performance > Enable Journaling
• Frontview > System > Power > Disable disk spin-down
• Frontview > Volumes > Volume Settings > Snapshot > Delete any active snapshots & turn off snapshot schedule

Then remove the disk, reboot the NAS, and then reinsert it.

Ok, all those values were as you indicate. On the 26th we tried to restart the NAS.

Sorry, we'll restart the nas on December 26th. It isn't possible before.

Hi,

When restarting the NAS the RAID began to be rebuilt.

One question:

The NAS is hot swap, should not it synchronize automatically without restarting?

It should have, but obviously didn't in this case.

Sometimes when a disk fails, the linux drivers will mark it's SATA port as down (depending on the details on how the drive failed).  When that happens, the system needs to be rebooted.  There might be other ways that this can happen too.
