I have an X4500 thumper box with 48x 500gb drives setup in a a pool and split
into raidz2 sets of 8 - 10 drives within the single pool.
I had a failed disk with i cfgadm unconfigured and replaced no problem, but it
wasn''t recognised as a Sun drive in Format and unbeknown to me someone
else logged in remotely at the time and issued a zpool replace....
I corrected the system/drive recognition problem, drive seen and partitioned all
ok but zpool showed two instances for the same drive, one as failed with corrupt
data, the other as online but still in a degraded state as the spare had been
utilized.
I tried a zpool clear device, zpool scrub, zpool replace all with no joy...then
and i kick myself now i thought i ''ll detach and reattach the drive....
Drive detached no problem, no questions asked, failed drive still in zpool
status, online one gone, reattach dosn''t seem possible.
As a temporary solution in case of further failures i''ve attached the
new drive as a hot spare...
My question is....how do i reattach the drive to the raidz2 set?
Can i use the replace command to replace the currently used spare with the new
drive if i first remove it as a hot spare?
Or do i have to delete the whole pool and restore 24 TB of data...please
no....!!!
