clvmd fails to start with "Unable to create DLM lockspace for CLVM: Transport endpoint is not connected' in RHEL 5 or 6
Issue
- After reboot, none of the nodes will mount the SAN gfs2 file systems. Need to restore entries in
/devfor the file systems. - Even though I started
clvmd, logical volumes are not found in/devand I can't mount GFS2 file systems - When I start
clvmdI see "Transport endpoint is not connected"
