Volume Data degraded error
Hi we have a Netgear 314E, Raid 5 and I keep getting this error. I have fixed it once by running balance and defrag but it is back again. The firmware is 6.6.0 and we have Egnyte Storage sync runni...
Hi uptown30,
I think the problem is with this:
Device: sda
Controller: 0
Channel: 0
Firmware: 01.01K02
Class: SATA
RPM: 7200
Sectors: 3907029168
Pool: data
PoolType: RAID 5
PoolState: 3
PoolHostId: 7c6e33a8
Health data
ATA Error Count: 0
Reallocated Sectors: 0
Reallocation Events: 0
Spin Retry Count: 0
Current Pending Sector Count: 31
Uncorrectable Sector Count: 31
Temperature: 44
Start/Stop Count: 15
Power-On Hours: 23184
Power Cycle Count: 15
Load Cycle Count: 6There are uncorrectable and pending sectors already. Normally these are indicators that the HDD is faulty or getting there.
Are you using X-RAID2?
Volume in a degraded state as far as I know should still work, it just cannot tolerate anymore HDD failure.
I would suggest that you try to do a back-up of your files then have the HDD above be checked then replaced.
Regards,

This says that disk 1 (Channel 0) is starting to fail. There might be other issues that show up in other logs (mdstat.log for instance).
Balance and defrag won't fix degraded volume errors btw. Only resyncing the array can do that.
If we do have to resync the array, does this means I have to back up the data, break the array and recreate it?
sda is marked as failed on the data volume array. I would replace that disk.
I have just rebooted the NAS and now it is indicating it is resyncing the volume however under System, Performance, Status it does indicate a yellow dot to Disk 1. Okay if I have to replace it, can I get some guidance what I have to do? I will order a 2 TB drive for one thing tomorrow.
