Hi guys,
I know the Red Hat kernel-2.4.9-13SGI_XFS_PR1 is in testing still, but
massive I/O errors occur when I run bonnie++ on my 1.12TB FS - the rest of
the partitions seem to be behaving themselves, tho.
I am not seeing it here even after pounding on it heavily. I do have
problems that performance degrades over time (> 1 day). But I think this is
more of a VM issue.
The good news is that this is still 30x faster then the old NCR MP-RAS box :-)
My manager was used to seeing performance halved when starting a second
database session. Now this happens after the 3rd concurrent session. Even
when running 8 concurrent dump and reload session in Progress 8 and 9
databases it handles it well.
Oh yeah, before I forget. People with AMI megaraid controllers should
update the firmware of their card. The newer version is a lot faster. Going
from 1.57/3.13 to 1.61j/3.17 improves the read perfomance in the same
configuration (raid 1 or 10). In my case it went from 58MB/sec to 71MB/sec
which is a nice perfomance upgrade without costing anuything :-)
I'll try to get the error messages next time I boot it up.
Yes please. This might be related to the size of your fs.
Cheers

Every program has two purposes one for which
it was written and another for which it wasn't
I use the last kind.
