[OmniOS-discuss] Multiple faulty SSD's ?

[Shaun McGuane]

Hi List,

I want to report very strange SSD behaviour on a new pool I setup.

The hardware is a HP DL180 G6 Server with the LSI 9207-8i Card
And 8x 1TB Samsung SSD Pro drives. Running omnios-10b9c79

All the drives are brand spanking new setup in a raidz2 array.

Within 2 months the below has happened and there has been very
Little use on this array.

  pool: SSD-TANK
state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.
  scan: scrub repaired 23K in 1h12m with 0 errors on Mon Jul 25 20:13:04 2016
config:

        NAME                       STATE     READ WRITE CKSUM
        SSD-TANK                   DEGRADED     1    67    35
          raidz2-0                 DEGRADED     4    72   113

            c5t50025388401F767Ad0  DEGRADED     0     0    19  too many errors
            c5t50025388401F767Bd0  FAULTED      0     0     0  too many errors

            c5t50025388401F767Fd0  ONLINE       0     0     1
            c5t50025388401F7679d0  ONLINE       0     0     2
            c5t50025388401F7680d0  REMOVED      0     0     0
            c5t50025388401F7682d0  ONLINE       0     0     1

Can anyone suggest why I would have this problem where I am seeing CKSUM errors
On most disks and while only one has faulted others have been degraded or removed.

Thanks
Shaun
