I have an unraid array of 4 disks + parity, all are individual ZFS volumes.
One of the disks just suspended itself:
"zfs clear" seems to hang (but does reset the CKSUM counter to zero.
Replacing the SATA cable seems like an obvious next step.... but I worry if I stop the array to swap the cable or reboot, if I would be able to start the array again, or will I get stuck into maintenance mode or something if the drive won't mount.
I don't have a huge amount of time to deal with it today, and since unraid doesn't see it as "failed", the contents aren't emulated (users just get errors when accessing anything on that disk), and don't want to get stuck having everything offline in maintenance mode overnight.
