RE: 20040727: Software RAID on Solaris x86

Thanks.  I am using 10k rpm SCSI disks and SW RAID.  Apparently
the stripe I was using was too big.  I went down to 8kb and it
works fine now.

BTW I would highly encourage checking out Solaris x86 again.
They are shipping their new C and FORTRAN compilers now,
plus a lot of speed enhancements have been made to UFS.
Sun is even selling reasonably priced Opteron powered
desktops and workstations and servers (Solaris x86).

Robert,

I "found" this inquiry in our inbox.  Sorry for the trdy reply.

Yes, on more than one, in fact.

It turns out that we were using a hardware RAID with SCSI disks,
not a software RAID.

Back when we used the x86 platform for our in-house data decode
box, we used hardware RAID.  We now us a FreeBSD box for the same
purpose, and it has been having RAID prob.ems recently.  For a long
time we used hardware RAID on it, and had no problems.  For some
reason, recently the RAID would "blow-up" (disappear) during operation
or after a reboot.  This got to be so bad, that we ripped out the
RAID card and went to using a software RAID.  Again, this is under
FreeBSD.

>Assuming you are running an LDM on that box.

Yes.

>Thanks,

Sorry for the tardy reply.

Cheers,

Tom
