We have been using LSM at our site for the last two major releases.
3.x and 4.x. The primary reason was to mirror the system drives and
the swap drives which were on the local shelf. Now with V5.1, we can't
mirror the Cluster / /usr and /var(Not supported yet). So we thought
it was a good opportunity to get rid of LSM because on Clusters we can
place everything on HSx controllers and use hardware mirror. One less
layer of software or metadrivers to go through to do I/O. Also the
other reason we had LSM on the previous releases was because it
allowed us to do volstat and we could trouble shoot the hotspots in a
database using that. There was one other point that someone brought up
and that is the ability to deport diskgroups and being able to
reimport them again. We are trying to evaluate the pros and cons.
Anyone have any thoughts/ideas/feelings about this? Please share them
with us....
Also, if anyone knows of something equivalent to volstat but something
that would run on a non-LSM system, I would be glad for the
information. We know about advfsstat and iostat but is there anything
else out there.
