Troubleshooting MooseFS Mount Errors and Related Issues
This guide details common MooseFS mounting problems—including bad mount points, firewall port blocks, error messages, and incomplete disk scans—and provides step‑by‑step commands such as killing processes, unmounting, remounting, and checking services to resolve these issues.
Problem 1: After unmounting MooseFS (mfs) and remounting, the command /usr/local/mfs/bin/mfsmount -H 192.168.103.101 /mnt/ returns fuse: bad mount point `/mnt/': Transport endpoint is not connected . The suggested solution is to kill the related processes, run umount , and then mount again, using commands such as ps aux | grep mfs and umount -l /mnt before re‑executing the mount command.
Problem 2: Firewall blocking on port 9422 prevents proper operation. The screenshot shows the firewall configuration that needs to allow traffic on this port.
Problem 3: After changing file owner and group, remounting mfsmount and restarting the mfschunkserver service are required to clear the reported errors.
Problem 4: Disk scanning operation did not complete, as shown in the screenshots. The images illustrate the incomplete scan status and suggest checking the scanning process.
Problem 5: mfsmount fails to mount. The accompanying screenshot shows the mount point not being established.
