Thank you all for having been so kind in your responses and help.
However, there is one more set of questions I have.
Does the md (software raid) have disk size or raid volume limits?
If I am using such things as USB or 1394 disks, is there a way to use
labels in /etc/raidtab and with the tools
With using RAID5 you can choose yourself howmany hot standby/failover disks
you want to use. The number (or ratio) of disks used for failover of your
raid will determine the chance that you have when one disk fails and complete
failure of a raid.
It is still pretty safe just to have 7 active dis

[Out-of-date now,
XFS is an SGI project.
http://oss.sgi.com/
I've been using it for quite a while and am quite happy with it; it is
very fast and very fault tolerant. The only warning I'd like to give
about it is it seems that some Linux developers seem to have a bad taste
in their mouth when it comes to XFS; go

XFS is from SGI.
PV = the device
VG = groups of them (the RAID5 array?)
LV = what? the file system?
So, from what you are telling me, and the man page, 2.6.x with LVM2 can
have basically any size of PV, VG, and LV I want.
Am I flawed in my understanding?
Thank you,

Confused over terminology?
Tie PVs together to form a VG, then divide VG up into LVs.
Si
A logical volume in LVM will not handle more than 2TB. You can tie together
the LVs in a volume group, thus going over the 2TB limit. Choose your
filesystem well though, some have a 2TB limit too.
Disk size: What are you doing with it. 500GB disks are ATA (maybe SATA). ATA
