Hi forum,

I did something stupid the other day, managed to connect an external disk that 
was part of zpool A such that it appeared in zpool B. I realised as soon as I 
had done zpool status that zpool B should not have been online, but it was. I 
immediately switched off the machine, booted without that disk connected and 
destroyed zpool B. I managed to get zpool A back and all of my data appears to 
be there, but I have a data error which I am unable to track. Apparently it is:

DATASET 0, OBJECT a, RANGE lvl=0 blkid=0

I have found this line from output of zdb:

Dataset mos [META], ID 0, cr_txg 4, last_txg 1759562, 406M, 362 objects

Is anyone able to shed any light on where this error might be and what I might 
be able to do about it? I do not have a backup of this data so restoring is not 
an option.

Any advice appreciated.

Thanks,

Matt
