Ooops... degraded ZFS pool due to loose SATA cable

[Hexland]

So one of my drives had a loose SATA cable, and went offline for a bit when I bumped the machine...

The ZFS pool is made up of 6x2TB drives (ZFS-Raid2) plus a 60Gb SSD as a cache drive.

Code:

 zpool status
  pool: ZPOOL01
 state: DEGRADED
status: One or more devices could not be opened.  Sufficient replicas exist for
        the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

The online option available through the GUI is 'replace' - but I don't seem to have the option of just re-initializing the disk that went offline (there's nothing wrong with it - it was just the cable (which has since been replaced))

What's the procedure for bringing this drive back online and resilvering?

Thanks

What's the procedure for bringing this drive back online and resilvering?

If the drive was showing as OFFLILNE then you would just

Code:

 zpool online pool device

It came up as UNAVAIL though. What's the output of:

Code:

camcontrol devlist

gpart show

Hmmm... after a quick reboot, seems to be back online again

Code:

 camcontrol devlist
