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...

Hello!
Yesterday we hit something like this on 4.1.2
Centos 7.5.
Volume is replicated - two bricks and one arbiter.
We rebooted arbiter, waited for heal end, and tried to live migrate VM to another node ( we run VMs on gluster nodes ):

after this I/O on /balamak.img was blocked.
Only solution we found was to reboot all 3 nodes.
Is there any bug report in bugzilla we can add logs?
Not aware of such bugs!Is it possible to turn of these locks?
Not sure, will get back on this one!
btw, found this link
https://docs.gluster.org/en/v3/Troubleshooting/troubleshooting-filelocks/
tried on another (test) cluster:
[root@marduk ~]# gluster volume statedump pool
Segmentation fault (core dumped)
4.1.2 too...
something is wrong here.
Thank you!
