I've seen this here a few times lately. Make a separate USB disk with 8.3-Beta, boot from that and check your zpool status/do a scrub.

Replacing a disk can take awhile, for example on my system with 5 disks (2TB), it took about 10 hours if I remember.


Your problem is something different, I've seen several people here lately that it happened to. Search a little....

After asking the Oracle (Google) I did the following:

zpool scrub –s <pool>
zpool clear <pool>
Reboot.

After this FreeNAS reports
[root@freenas ~]# zpool status
pool: Data
state: ONLINE
scrub: none requested

Usually you ask the Oracle before you post, but glad you got it.

I did not got it after all :(

The next scrub on FreeNAS 8.2 restarted the resilvering process.
Ended up with your suggestion to boot on 8.3 BETA 1, import the volume and do a scrub.
The scrub ended with no issues!
Then I rebooted on FreeNAS 8.2 without any issues. :)

Be very carefull. 8.2 may report no issues, in reality there may be issues. 8.3 started to resilver with my machine where 8.2 would report nothing was the matter. See also http://forums.freenas.org/showthread.php?8160-Replace-a-drive-without-a-spare

8.3 started to resilver with my machine where 8.2 would report nothing was the matter.

That statements enough to make me upgrade my 8.2 machine to 8.3 as soon as it's stable. I'll keep my eyes open as to why this is true, but I think it is true since I've seen those in the know recommend using 8.3 to address some file system issues.

The reason why 8.3 is often "superior" for some ZFS operation is the newer code for ZFS. 8.3 supports v28 of ZFS and has numerous bug fixes etc.

I have just been through a disk replacement processes on my server, replacing 3X1TB drives with 3X2TB drives (RAIDZ). Each single disk replacement took around 8 hours to complete. When running a zpool status, the amount of time left to complete and percentage complete is no where near accurate. It states 100% complete yet runs for another hour or so.
