It is a LUN that has a FS, there is no constant I/O to it, but should't i except that the System will shout at me?
I see only warning msgs in the dmesg that LUN assignments on the target were changed and SCSI doesn't preform remap...

by the way, rescan-scsi-bus.sh doesn't help - it doesn't remaps the LUN, only reset of the stack does..
