Suggestions for SuSe 10.2 LVM partioning for 4 drive terabyte server

faron_young · 05-08-2007, 12:12 PM

I have the following drives in my system:

/dev/hda 232.8 GB IDE
/dev/hdb 232.8 GB IDE
/dev/hdc 232.8 GB IDE
/dev/sda 372.6 GB SATA

I want to put the /boot, /usr, swap, and /home on the SATA drive, then I want to create a volume group using the remaining SATA and all 3 IDEs. I had planned to use EXT3 across all paritions (with the exception of swap).

Am I on the right-track? Would anyone have any better suggestions for this configuration?

Thanks - Faron

what about a drive failure ?
lvm won't help with that at all.

I was under the impression that you could still place VGs in RAID. Was I misinformed?

sure, I do that myself. LVM just gives huge flexibility to shift around space as needed ;-)
you just didn't mention you were going to have a raid below the lvm layer.

the only problem that comes to my mind is this:

for raid to run without wasting space, the partitions combined to raid (e.g. linux software raid5) should be of equal size. otherwise the smallest partition sets the limit for all the other ones. so if the "rest" of your sata drive is much smaller than your ide drives, you'll be wasting space.

ideally whats left of your sata drive after creating /home and so on should match the ide drives.
