Hello,

I went a week or so with a ZFS pool with 8 SATA drives via SlimSAS and two via SARA on a ASRock TRX50 WS and today the SlimSAS connected drives (via 2x SFF-8654 4i connectors) are just not cooperating. 1-2 show as REMOVED when I reboot the server and when I run `zpool clear <poolname>` the rest show as UNAVAIL.

state: SUSPENDED

status: One or more devices are faulted in response to IO failures.

action: Make sure the affected devices are connected, then run 'zpool clear'.

errors: List of errors unavailable: pool I/O is currently suspended

Since my two SATA drives always show as ONLINE I am highly suspicious of the SlimSAS on the motherboard. I have a couple LSI 9207-8i's sitting in a case in my storage unit, am I best off just switching over to these or is there more debugging I can do here? If I do switch will ZFS recognized these as the same drives even though the adapter changed?

Thanks!
