Overkill. Why have so many different raid running? Besides, raid5 has
been iffy and I wonder how stable raid6 is.
I think you're right. I've lost the raid every time when I pulled out
the boot drive.
After install create
Md10 raid10 - 4th partition of all drives - /data
What advantages, if any, would lvm have over this set up?
How about flexible filesystem resizing? If you did it the way I
suggested: 512MB /boot, 512MB /tmp, you have like 960GB of space to
carve anyway you like. You also get lvm snapshots which you won't get
with raid seeing that this is supposed to be a backup server too.
Yea, I think for these reasons I will use lvm. I have set up a system
as follows:
/boot raid 1 200mb 4 drives no spares (I guess this makes 4 copies of
the data?)
2 250mb raid1 arrays over the 4 drives (2 drives each ) for swap
rest of space in 2 raid 1 arrays
lvm on top of the 2 raid1 arrays
/ 10gb on lvm
/data 50gb on lvm
/backup 250gb on lvm
rest of space left free to allow for resizing and adding of partitions
with lvm
I will pull out a drive tommorow and see how resilient this is. Does
this sound like a good solution?
