I got an alert last night, and I now have two disks with SMART warnings. What should I do, to avoid losing 9TB of data ?
I have a TS-412 running 4.1.1 Build 20141101
4 x Seagate ST3000DM001 3TB disks
RAID 5
Disk 1 & 2 are fine.
Code: Select all
Disk 1 all Good
Disk 2 all Good
Disk 3 gives :
Desc Val Wor Thr Raw Stat
Reallocated_Sector_ct 100 100 036 0 Good
Current_Pending_Sector 100 100 000 8 Warning
Offline_Uncorrectable 100 100 000 8 Warning
Disk 4 gives :
Desc Val Wor Thr Raw Stat
Reallocated_Sector_ct 100 100 036 32 Warning
Current_Pending_Sector 100 100 000 56 Warning
Offline_Uncorrectable 100 100 000 56 Warning
However, Disk 3 has some pending reallocations, and no reallocated sectors yet.
My two questions are :
* How can I force Disk 3 to reallocate the 8 pending sectors, and rebuild the data from the other 3 disks ? (Assuming the 8 sectors don't line up with any bad sectors on disk 4)
* If I pull Disk 4 now and replace it, does that mean the 8 pending sectors on Disk 3 will be lost and corrupted, as the RAID cant rebuild the data as it missing the sectors in Disk 3 ?
Thanks !
Jon.
