RE: what i need is a little attention-RE [linux-lvm] SoftRaid and LVM Jean-Eric Cuendet

I'll give you my setup.
I have a 5 36Gb SCSI disks machine which do MD+LVM+ext2 on them
Each disk is splitted in 4 (~9Gb each partition) and then grouped 5 by 5
to form 4 MD (md5, md6, md7, md8) each ~36Gb in RAID5.
Then these 4 MDs are added in a VG and LVs are created for each need
(CVS, HOMES, FILES, ...). 
The machine is a PIII 733 with 256Mb RAM and has RH7.1 installed
I use MD 0.90.0, LVM 1.0.1rc1 and e2fsprogs 1.23. I have NO reiserfs nor
XFS nor JFS.

All that works fine for me with little problems since upgrade to

Each partition on the physical disk is marked as fd (Linux RAID
autodectect) then pvcreate is made on /dev/md[5678] . There is no need
to put either "Linux Native (83)" nor "Linux LVM (8e)" on the /dev/md1
or something like that. Just the fd on physical partitions will do the

Hope this helps.
