Any ideas? GFS?
GFS (GFS2 being the supported version) is about multiple nodes using the same shared block devices, pretty much the opposite of what you need.
Good! I've never managed to get it to work anyway!
To satisfy the "remove one drive" criteria you want to have some user-space system for synchronising files by copying them around.
Something like having the largest drive mounted as the root file system’s /home and then using a cron job ever hour to rsync the data (or portions of it) to the smaller drives? rsync -avh --include '*/' --include '*.php' --prune-empty-dirs /home/ /mnt/code_drive rsync -avh --include '*/' --include '*.jpg' --prune-empty-dirs /home/ /mnt/images_drive rsync -avh --include '*/' --include '*.sql' --prune-empty-dirs /home/ /mnt/data_drive I like this idea as it combines two of my favourite things, rsync and being a cheapskate! Any pitfalls? Cheers P
