Hello everyone,
 
I'm running an oVirt cluster on top of a distributed-replicate gluster volume and one of the bricks cannot be mounted anymore from my oVirt hosts. This morning I also noticed a stack trace and a spike in TCP connections on one of the three gluster nodes (storage2), which I have attached at the end of this mail. Only this particular brick on storage2 seems to be causing trouble:
Brick storage2:/data/glusterfs/hdd/brick3/brick
Status: Transport endpoint is not connected
 
I don't know what's causing this or how to resolve this issue. I would appreciate it if someone could take a look at my logs and point me in the right direction. If any additional logs are required, please let me know. Thank you in advance!
 
Operating system on all hosts: Centos 7.9.2009
oVirt version: 4.3.10.4-1
Gluster versions:
- storage1: 6.10-1
- storage2: 6.7-1
- storage3: 6.7-1
