OpenVZ: Mounting Host Devices/Partitions/Directories In A Container With Bind Mounts (Debian/Ubuntu) Sometimes you are in a situation where you need to mount a hard drive, partiiton or directory from the OpenVZ host inside an OpenVZ container - for example, you add a fast SSD to the host and want to put your container's MySQL databases on it to make MySQL faster. This tutorial explains how you can mount host devices/partitions/directories in an OpenVZ container with bind mounts.

Just wondering, if you make backups is the content of /var/lib/mysql in your container being stored in the backup?

Thanks for the great tutorial - wondering if there's any way to say segment off this SSD (which is exactly what im doing) into size limited chunks for each container, much like proxmox/vz already segments up /var/lib/vz with limits. Rather give 10 or 15 gigs of the small SSD to each container than let them all compete for it.

You should be able to assign individual partions in the bind mount script. If your ssd is /dev/sdb and has partitions /sdb1 and /sdb2 you would then use the specific partion that you want to bind to the container in the script.
