xfs EVMS problem

[Sebastian Lenz <sebastian.lenz@xxxxxxx>]

we have an ISCSI system with two heartbeated nas and a 12 TB private 
container behind this. after a firmware update EVMS still lists the 
container but without any filesystem so we cant access to the storage.

we had a lot of discussions and help ending in this command:

xfs_repair -v -n /dev/sdb1

with the result

...............................................................................................................................................................found 
candidate secondary superblock...
unable to verify superblock, continuing...
.found candidate secondary superblock...
unable to verify superblock, continuing...

and a fatel error like "cant find super block".

is there anyone who can help us. we dont want to lose the data and we 
are willing to pay. thank you
