Hi there,
We have been using ZFS for our backup storage since August last year.
Overall it's been very good, handling transient data issues and even
drop outs of connectivity to the iscsi arrays we are using for storage.
However, I logged in this morning to discover that the ZFS volume could
not be read. In addition, it appears to have marked all drives, mirrors
& the volume itself as 'corrupted'.
>From what I can tell I'm completely unable to perform a zpool import and
the only solution according to SUN is to 'destroy and recreate the
volume from a backup'. That's not overly helpful considering this IS our
backup source AND the fact we thought we had redundancy covered through
the implementation of multiple mirrors. The arrays themselves are
configured in 5 x 880GB RAID5 LUNs per array. These 5 are then mirrored
to their matching 5 on the other array.
To be honest, I'm pretty disappointed this occurred. I was of the
assumption that by setting up a set of mirrored volumes I would avoid
this exact problem. Now, for whatever reason (perhaps triggered by an
iscsi connection timeout) ZFS has decided all devices in the entire
array are corrupt. I guess that's why assumptions are the mother of
all ......s. :)
While this data isn't mission critical it IS of significant use to us
for historical analysis purposes so my assistance would be greatly
appreciated.
I've included a dump of the zpool import response below.
Thanks for your help!
