I have an XPEnology build running DSM 6.1.7-15284 Update 3 on an older Dell/Compellent SC030 Storage Controller. The specs are as follows:
CPU: Intel(R) Xeon(R) CPU E5240 @ 3.00GHz
RAM: 3172 MB
Disk Controllers: 2 x Fujitsu DS2607-8i crossflashed to an LSI 92118-8i with firmware P20 and in IT mode.
There are 16 2TB IBM SAS drives (a mix of IBM-ESXS HUS723020ALS64 and IBM-XIV ST2000NM0043 A4) attached to the controllers via the SAS-836TQ backplane.
This system previously had a mix of 16 1TB SATA drives and had no issues beyond bad sectors from old drives. It was in a RAID5 configuration.
With the new setup, each time the RAID6 array rebuilds it immediately crashes at the end taking out 10 drives.
Eight of the drives indicate Status=Crashed, S.M.A.R.T. Status=Normal and no bad sectors
Two of the drives indicated Status=Initialized, S.M.A.R.T. Status=Normal and no longer belong to the RAID Group.
When I reboot the device, the eight crashed drives indicate that they are working normally and rejoin the group. I am then prompted to rebuild the array with the two other drives.
When installing the drives I booted from the USB in re-installation mode and built the RAID from scratch.
I have backups of the data, but am unsure of how to proceed.
Please let me know what I can do to prevent the array from crashing.
The volume is formatted as BTRFS.
