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!
