Hi.
Im running freeNAS v.0.7.2 with zfs v3 and zpool v13.
I was trying to upgrade my raidz1 from 1 TB drives to 2TB drives, replacing
1 drive at a time.
here's the current layout:
freenas:~# zpool status
pool: guitar
state: DEGRADED
scrub: resilver completed after 0h0m with 0 errors on Sat Jul 16 17:19:48

ad18.nop ONLINE 0 0 0 116K
resilvered
spares
da1 AVAIL
errors: No known data errors
Without taking ad4.nop offline, i turned the machine off, replaced the
drive, and did a "zpool replace guitar ad4.nop ad4"
It started replacing the drive, but got I/o write and read errors, so it
restarted (happened like 30 times per minute).
I have tried everything.
zpool replace guitar ad4.nop /dev/da1 (can't replace because already being
replaced)
zpool offline guitar ad4.nop (no valid replicas)
zpool offline guitar 9203819577564534483 (no valid replicas)
zpool clear guitar ad4.nop
zpool export / import (thus the 9203819577564534483, it said ad4.nop before)
The spare was added later to try and put that in instead of ad4.nop, without
luck.
The box only have 6 sata ports, so I am unable to connect the drive i was
trying to replace ad4.nop with.
I do have another computer that i could use as a temp server, but that one
also has 6 sata ports.
The next raidz1 will be with only 5 drives, and 1 spare ( so i dont have to
meet this problem again)
The problem now is, that i can't access the files that are on the NAS, thus
being unable to do a backup of it. ( I can transfer like a coulple of GB,
then the whole box gets unreachable (web, ssh ftp).
Any Idea how to solve this?
Best Regards
Jørgen
