Hmm, but unfortunately I was too quick to say the patch fixed the hang. It is much more rare, but I can still get a hang. I just got the following running vgcreate against an DM mpath (rq-based) device:Can you please try this one instead?Still hit the hang on the 5th iteration of my test: while true ; do ./test_dm_discard_mpath.sh && sleep 1 ; done Would you like me to (re)send my test script offlist?
