Good day,
Does anyone know if LVM is supported on software raid5. I understand it
can run on a striped set being raid0 , but heard that it doesn't support
raid5. Is this true or has this been resolved.
Thanks,

Works fine for me:

OK, thanks.
I was messing with SUSE 7.3 and in their LVM control panel, it only
seemed to suport linear or striping.
How have you done yours? Do yo do it from the command line and are any
specific versions/packages required for this?
Are you using the Sistina LVM package?
Thanks,

LVM by itself does not implement RAID5. What people do is to use the md
driver (standard Linux software RAID) to create a RAID device and then put
LVM on top of that.
Hope this helps sorting out the confusion.

LVM itself can do striping or concatenation of PVs, but Linux has a
complete software RAID system and it will do RAID5 just fine. Build a
RAID array and run pvcreate on it. The Software-RAID-HOWTO has some
useful info on building the array.
