Subject: Partitioning / LVM Advice RHEL4
I am setting up a Dell poweredge box with two 70 g hard drives. The default LVM partition has one / with everything in it, and two volume groups, one for each scsi drive.
Since I havent put the machine in production yet, I am wondering if I should manually reduce the one from 70 to about 40, and save off about 30 GB? This will be running one application, nothing else to speak of, but I am a bit paranoid about log files filling up partitions and the like, especially on a server running an app like this day in and day out. I am also paranoid about having one big /
Also I am wondering if mirroring is something I should even consider. I don't think we need anywhere NEAR 140 gigs. Maybe I could just make manual copies of certain files and leave them on my 'extra' 30 GB partition.
If anyone has a good general 'rules of thumb' type link or paper please share.
Here's an example of one of my systems:
Filesystem Size Used Avail Use% Mounted on
/dev/vg00/lvol1 2.0G 312M 1.6G 17% /
/dev/cciss/c0d0p1 483M 20M 439M 5% /boot
/dev/vg00/lvol2 496M 8.1M 463M 2% /home
none 1007M 0 1007M 0% /dev/shm
/dev/vg00/lvol6 2.0G 33M 1.9G 2% /tmp
/dev/vg00/lvol7 6.9G 1.9G 4.8G 28% /usr
/dev/vg00/lvol4 2.0G 87M 1.8G 5% /var
/dev/vg00/lvol5 2.0G 33M 1.9G 2% /var/adm
We ahve only been using 36GB drives, and don't even utilize all of that space.
