I have a glusterfs mount outside:
| Quote: | /etc/glusterfs/glusterfs.vol on /media/glusterfs type fuse.glusterfs (rw,allow_other,default_permissions,max_read=131072)
|
I made a mount and umount script:
| Quote: |
/etc/vz/conf/126.mount:
#!/bin/sh
source /etc/vz/vz.conf
source ${VE_CONFFILE}
mount --bind /media/glusterfs/var/www ${VE_ROOT}/var/www
/etc/vz/conf/126.umount:
#!/bin/sh
source /etc/vz/vz.conf
source ${VE_CONFFILE}
umount ${VE_ROOT}/var/www
exit 0
|
vzctl start 126 was ok.
vzctl stop 126 says:
| Quote: |
Stopping container ...
Container was stopped
umount: /media/glusterfs/var/www: Transport endpoint is not connected
umount: /var/lib/vz/root/126/var/www: not mounted
umount: /media/glusterfs/var/www: Transport endpoint is not connected
umount: /var/lib/vz/root/126/var/www: not mounted
Container is unmounted
|
I started glusterfs in debug mode, and it said:
| Quote: |
[2009-10-29 11:19:09] N [fuse-bridge.c:2544:fuse_thread_proc] fuse: unmounting /media/glusterfs/
[2009-10-29 11:19:09] W [glusterfsd.c:928:cleanup_and_exit] glusterfs: shutting down
|
but mount still exist. Trying to list content said "Transport endpoint is not connected".
Which part of OpenVZ kills my glusterfs and how can I fix it?
linux-2.6.18-14-fza-686, fuse-2.7.4glfs11, glusterfs-2.0.7

It seems that one of init script umounts it inside the container.
Can I hide these mounts inside?

Hi,
I don't know what does vzctl do exactly when you are stopping the container, but through testing I've seen there is a way of making sure glusterfsd is not killed by it, that is unmounting it from within the guest before stopping.
If your mount file is like this:
mount -n --bind /local/glusterfs/mountpoint /var/lib/vz/root/VEID/path/to/directory
Easiest solution is including this command in the stop script:
umount /path/to/directory
The stop script is run before any force umount happens from within the host.
I still would be interested in knowing why does vzctl kill glusterfs if you don't do that prior to stopping the vm.
