Description of problem: Sometimes the glusterfs partition on one of the servers of my cluster is disappearing from mount. When I try to mount it back, OS says that the partition is busy, but not accessible. I have to do a "umount -l" and mount it back. This causes my VM to crash, so not so nice. How can I troubleshoot this ? Thanks in advance How reproducible: Don't know how to... Actual results: Partition disappearing Expected results: Partition should stay mounted :)
Can you post anything from the logs (probably in /var/log/glusterfs) on the client? That might show if you're getting transport errors (most likely) or something else.
