Subject: Gluster mount troubleshooting
I'm running glusterfs 3.4.3 built on Apr 14 2014 22:05:07
I have a two-brick volume created, but when I try to mount from the client machine I get an error:
# mount -t glusterfs -o backupvolfile-server=server2,volfile-max-fetch-attempts=2,log-level=WARNING,log-file=/var/log/gluster.log server1:/webs /mnt/glusterfs/
/usr/bin/fusermount-glusterfs: mount failed: Invalid argument
/usr/bin/fusermount-glusterfs: mount failed: Invalid argument
Mount failed. Please check the log file for more details.
Can I get troubleshooting advice, please?
The log file shows:
