This may be why our Linux LPAR is very slow.
Perhaps we should change from ReiserFS to ext3.
Is it simple as copying to somewhere else, doing mkfs and then copying
back?
If someone has a procedure, please let me know.
Thanks

Subject: Re: [Linux/390] Re: Filesystem conversion ext2 to
Reiserfs
Slightly apples-to-oranges, but we discovered that using reiser with
virtualization on Intel led to huge performance losses. With 15 UML
machines
with reiser root drives, we were seeing 100% CPU load on the host while
idle,
and almost unuseable performance in the guests. Changing to ext3 w/out
data
journaling (default behavior) solved this and dropped the idle host load
to
about 3%.
