Re: [CORRUPTION FILESYSTEM] Corrupted and unrecoverable file system during the snapshot receive

(synthetic resend)

Hi.

Is possible that there are transfers, cancellations and other, at the same 
time, but not in the same subvolume.

My script checks that there are no transfers in progress on the same 
subvolume.

Is possible that the same subvolume is mounted several times (temporary mount 
at the beginning, and unmount at the end, in my script).


Thanks for all.


P.S. Sorry for my bad English.
