[Stgt-devel] segmentation fault trying to update LUN 0 ...

[Richard Sharpe]

Hi,

I was trying to add backing store to LUN 0 with this command and got a
segmentation fault:

   ./tgtadm --lld iscsi --op update --mode target --tid 1 --lun 0 -b
/root/data/hd_block
   Segmentation fault

Is it forbidden to use LUN 0? Here is what a SHOW shows ...

./tgtadm --lld iscsi --op show --mode target
