Re: [linux-lvm] lvm and md



Peter,
both ways are fine depending on your priorities.

I'ld prefer to group disks together with MD for resilience (i.e RAID1)
and then use those as LVM physical volumes to have the flexibility to allocate
space to logical volumes online.

More convenient this way rather than changing raidtabs which cause interruptions
to your volumes on size changes.

Because a core feature of LVM is to resize logical volumes online, the given
resizing capabilities of filesystems (i.e. reiser, xfs) allow you to
grow the filesystem online as well.
