XigmaNAS

Hi,

i wanted to move some big data from nas4free to linux, so i moved my pool harddrives to my linux box and mount it with zfs for linux (not the fuse one), everything worked great so far. After the first shutdown i could not see the pool in linux anymore, zpool import always gave me I/O error, so i decided to move them back to my nas4free box and transfer the files over slower network.

But, the pool is not found in nas4free anymore, i did try various imports:

# zpool import
- always did list the pool as FAULTED corrupted data, but with the raidz1-0 volume inside was "online"
# zpool import -f pool1
cannot import 'pool1': I/O error
Destroy and re-create the pool from
a backup source.
# zpool import -fF pool1
cannot import 'pool1': I/O error
Destroy and re-create the pool from
a backup source.
# zpool import -fFX pool1
cannot import 'pool1': one or more devices is currently unavailable

when i try to look up the pool_guid with zdb -l and use
# zpool import -fV 14147840165440994579
nas4free does reboot


full output:
zpool import
pool: pool1
id: 14147840165440994579
state: FAULTED
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using
the '-f' flag.
see: http://illumos.org/msg/ZFS-8000-EY
config:

pool1 FAULTED corrupted data
raidz1-0 ONLINE
ada2 ONLINE
ada3 ONLINE
ada0 ONLINE
ada1 ONLINE

What is troubling me a bit is that zdb told me i was using ada1.nop and ada3.nop before not ada1 and 3.

Am i totally screwed or is there some chance to get the data back?

Data is probably there.

What is the output of zdb -lu /dev/ada0 ?

additionally could you post the output of to check if something strange happened to your pool

# zdb -lu /dev/ada0

# zpool history
no pools available

It looks like your pool did not shut down correctly.

Labels 1 and 3 are invalid.

I am not sure what the situation is with the ada1.nop, and ada3.nop, but it is looking for them. Do you know why they existed or what they were supposed to do? They could be a factor if they weren't transparent.

The output for ada1, ada2, and ada3 will also be needed. There is a possibility that the other labels are in different states of completion, and this leaves ZFS unable to determine what should happen.

It also looks like you had another device in this pool besides those 4. Do you remember what it was? A log or cache drive?

There was a cache drive some time ago, yes.
ada1.nop and ada3.nop were the drives before (i didn't really set them up, but i remember them being part of pool1 before, instead of ada1 and ada3)
There was probably an unclean shutdown while the disks where in the linux box.

It seems you have only label 0+2 on all the drives, except ada2 which only has valid label 2. That might be the reason for the fail to import.

Try these, on the hope that maybe your missing device was actually a log:
zpool import -m pool1
zpool import -f -m pool1
zpool import -f -m -F pool1

If none of these work, the next steps are dicier. Any steps would warrant working with images, rather than the originals.

# zpool import -m pool1
cannot import 'pool1': pool may be in use from other system, it was last accessed by nas (hostid: 0x7f0101) on Sat Nov 22 17:13:19 2014
use '-f' to import anyway

# zpool import -f -m pool1
cannot import 'pool1': I/O error
Destroy and re-create the pool from
a backup source.

# zpool import -f -m -F pool1
cannot import 'pool1': I/O error
Destroy and re-create the pool from
a backup source.

no use

I did create images of the harddrives, what are the "dicier" steps?
