Subject: mvsas issues in 2.6.38, 8 SATA disks in RAID-6, local I/O seems fine,
NFS makes it error out a lot
Hi there,
for a while I've been following the issues with the mvsas controllers,
especially in combination with SATA drives. Since version 2.6.36 I
thought it was quite stable, the local processes at least didn't throw
off the 8 disk raid-6 array we have and I didn't really see any errors
at all.
Even on the 2.6.38 we run now (ubuntu 11.04 64 bit server) it was
stable. Emphasis on the was... all was fine until I started exporting
the volume through samba and above all, nfs. There's some vmdk's on
the volume now, which get put there by a backup application over
samba. This works reasonably (could go faster... :)), but then vmware
esx will attach to it over NFS and that's when the real misery starts.
It's completely unusable over NFS, errors aren't more than a couple of
minutes apart when ESX generates traffic and due to bus resets etc.
this means there is hardly any data coming from it whatsoever.
The errors we see are below. This box doesn't really run production
yet (well not with the disks on the marvell controller anyways), but
it will have to in a couple of weeks. In the mean time however I can
test/gather whatever anyone might need.
Kind regards,
