Concat Drives to Expand Disk Space

Have been needing some extra disk space to store our history of MySQL backups. Each night I do a hot backup of our MySQL databases on our RAID array. After the backup I move yesterday's backup off to another disk, and store a handful of day's worth of backups.

So my backup history disk was getting too full, setting off our alert system. I had a few older 9G drives in the machine and discovered it's pretty easy to concat those drives onto an existing drive. Added an additional 18G to the disk, which should give a little breathing room. At some point (when the drive concat is too small) will most likely replace the drives.
