I cannot mount or browse my image files that are backed up on the linux server using urbackup server 1.4.5 from the ubuntu trusty ppa
I have tried to mount several image files but they give the same error.
start_urbackup_server --mountvhd /media/BACKUP/urbackup/t420s-1/Image_C_141212-0242.vhdz --mountpoint /media/image
Using temporary mountpoint /tmp/tmp.1En9UsxesB
Starting VHD background process…
Starting mounting…
mount: you didn’t specify a filesystem type for /tmp/tmp.1En9UsxesB/volume
I will try all types mentioned in /etc/filesystems or /proc/filesystems
Trying ext3
mount: special device /tmp/tmp.1En9UsxesB/volume does not exist
I checked and the folder /tmp/tmp.1En9UsxesB/ does get created but sure enough there is no volume in there
hmmm maybe now would be a good time to mention that this is an OpenVZ container and the host OS (Proxmox) is running ZFS for linux as storage for urbackup being mounted onto the urbackup container like this at startup
mount --bind /tank/backups/urbackup /var/lib/vz/root/105/media/BACKUP/urbackup
I ran modprobe fuse without any error on the host OS (Proxmox) and added it to /etc/modules but i dont think that really has any effect on the containers and i get the error below inside the container, i think there is a way to add modules to the containers by edting /vi /etc/vz/vz.conf or something but it gets a bit confusing and sometimes requires reboots etc
modprobe fuse
modprobe: ERROR: …/libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file ‘/lib/modules/2.6.32-34-pve/modules.dep.bin’
there is some info here and i fooled with things for a bit but cannot seem to get things to work http://openvz.org/FUSE
Ok i have made a bit of progress i have gotten the
ERROR: Error mounting fuse filesystem
to go away by … and i am posting this here to help anyone who may find this helpful for OpenVZ
make sure your host has fuse in the kernel i added fuse to /etc/modules just in case
then also on the Host OS run this command
vzctl set VMID --devnodes fuse:rw --save
So now when i run /usr/sbin/urbackup_srv --plugin /usr/lib/liburbackupserver_fsimageplugin.so --plugin /usr/lib/liburbackupserver_fuseplugin.so --mount /media/BACKUP/urbackup/t420s-1/Image_C_141212-0242.vhdz --mountpoint /tmp/t420s-1 --loglevel debug

I get a volume created in /tmp/t420-1 as below but i am still lost as to how to browse my files
