SOLVED Disk shows "N/A" after resilver, Pool says everything is OK

[MisterPi]

Solution: Rebooted. I didn't know that was necessary, but I guess it is.

I've been having some disk woes of late, one of which will be detailed in another post ('tis a cautionary tale), but this one has me stumped

The other day I had a disk fail. It's on a motherboard SATA port, all of which have been reliable for several years. I offlined it, popped in another (refurb ST3000VN007), replaced the missing disk and everything resilvered. Pool status shows everything OK (AFAIK).

The disk in question is ada2p.
However the list of disks shows the newly added disk as N/A as opposed to being a member of the pool that contained the disk I replaced.
SMART tests are fine, showing no failures or impending failures that I can tell.

The disklist.pl output shows the disk as a member of the pool:

Code:

root@cervinia[~]# perl ./disklist.pl -i:zpool Pool.1-3TB -all -o:csv
partition;fs;label;zpool;zpool-location;zpool-mount;device;sector;disk;size;type;serial;rpm

Does anyone know whether this is something about which I should be worrying or how to fix it?

Thanks.
