Hi all,
Can anyone help with a ZFS problem I've been having? I have a single ZFS pool as shown below:
# zpool status
pool: vault
state: DEGRADED
scrub: resilver completed after 0h8m with 0 errors on Sun Jul 11 22:18:27 2010
config:
NAME STATE READ WRITE CKSUM
vault DEGRADED 0 0 0
mirror ONLINE 0 0 0
da0.eli ONLINE 0 0 0
da8.eli ONLINE 0 0 0
ad4.eli ONLINE 0 0 0
mirror DEGRADED 0 0 0
da1.eli ONLINE 0 0 0 10.0M resilvered
replacing UNAVAIL 0 7.42K 0 insufficient replicas
176228571956779269 UNAVAIL 0 7.79K 0 was /dev/ad6.eli
1650754158582652028 UNAVAIL 0 7.81K 0 was /dev/da99.eli
da9.eli ONLINE 0 0 0 10.0M resilvered
errors: No known data errors
However I can't seem to get rid of the replacing drives. What happened was that I tried to replace /dev/ad6.eli with /dev/da99.eli (because ad6.eli broke) and da99.eli was also faulty and so failed the replace.
How do I get rid of them? The array is otherwise healthy....
# zpool offline vault 176228571956779269

# zpool detach vault 176228571956779269
cannot detach 176228571956779269: no valid replicas
replace doeesn't work either.
ZDB returns:

How do I fix this? ZFS says that the array is degraded but it isn't really, I just can't get rid of this.
