Team, would be great to get this moving, and see if it makes sense for us
to make it a priority for 5.1 release, considering this is a stability
issue!

Ran into this issue too with 4.1.5 with an arbiter setup.  Also could not
run a statedump due to "Segmentation fault".

Tried with 3.12.13 and had issues with locked files as well.  We were able
to do a statedump and found that some of our files were "BLOCKED"
(xlator.features.locks.vol-locks.inode).  Attached part of statedump.

Also tried clearing the locks using clear-locks, which did remove the lock,
but as soon as I tried to cat the file, it got locked again and the cat
process hung.


I created issue in bugzilla, can't find it though :-(
Looks like there is no activity after I sent all logs...
