Because it can complicate a recovery, as you just experienced. Why did you feel a need to have /var setup as you did? Did you expect to fill it up quickly or a need for speed? You also have /tmp separate - do you expect more than usual activity there? Perhaps a better question would be - What is the purpose of this machine? If it's a just a fileserver on a home lan, you don't *need* to make it complicated, although learning is fun :-). Running a very active internet facing box with email, mysql, apache, etc. would probably call for a more complicated setup - which would actually make recovery & security easier/better. > > Here is my fstab: > /dev/md2 / ext3 defaults > 1 1 <--- md2 Software RAID1 > /dev/md1 /boot ext3 defaults > 1 2 <--- md0 Software RAID1 > /dev/md0 /tmp ext3 defaults > 1 2 <--- md1 Software RAID1 > tmpfs /dev/shm tmpfs defaults 0 0 > devpts /dev/pts devpts gid=5,mode=620 0 0 > sysfs /sys sysfs defaults 0 0 > proc /proc proc defaults 0 0 > LABEL=SWAP-sda3 swap swap defaults,pri=1 0 0 > LABEL=SWAP-sdb3 swap swap defaults,pri=1 0 0 > /dev/raid_vg0/raid_lv0 /mnt/raid ext3 defaults > 0 0 <--- Hardware RAID10 > > Before, home and var were under /mnt/raid directory and symlinked to > /home and /var.

Please advise. > I'm somewhat simple-minded - I like to keep the system that way :-). I split the partitions into 3 / swap /home either on a single disk or mirrored ( swap mirrored too ) - no lvm. For data storage I use lvm on raid on a separate mount point. Not saying you should do the same - it's just what I do. -- Toby Bluhm Alltech Medical Systems America, Inc.
