Umount stale glusterfs partition
- by Khaled
I am using glusterfs on several Ubuntu servers: two of them are running glusterfs servers in replication mode.
Without any clear error, the glusterfs partition became stale and the system shows this error when I try to access the stale partition:
Transport endpoint is not connected
Also, when running ls -l on the parent folder I get:
d????????? ? ? ? ? ? myfolder
I tried all types of commands that I can find to umount this partition, but I could not get it done:
umount -l /path/to/mount/point
umount -f /path/to/mount/point
Also, using fuser command to show processes accessing this folder did not work. Unload the fuse kernel module can not be done as it is clear from the kernel config that fuse is built into the kernel and not a loadable module. I found this line in /boot/config-2.6.32-24-server
CONFIG_FUSE_FS=y
I have been left with two options:
Reboot the system.
Create another mount point like myfolder2 and mount this again using sudo glusterfs -f /etc/glustefs/glusterfs.vol /path/to/folder2.
Of course, I have chosen to go with option 2.
Anyone faced such an issue before?
Anyone has a better solution for such a case?
