Please ignore my previous post. Those tests were done using WDC WD20EURS disks, which are apparently unreliable.
I have replaced the disks with Hitachi HDS72202 and have re-run the tests. With the stock mvsas driver from 2.6.38-8-server, I did a badblocks readonly test on all 5 spindles simultaneously, pulling approximately 80-100MB/s from each spindle, without any errors. I then did a software raid5 reconstruction (4 spindles read, 1 spindle writes) and that also worked fine without any problems. I noticed that the mvsas driver for 2.6.38-8-server contains some of Andy Yan's patches, but not all. Apparently the parts included are now sufficient for my hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/554398 Title: Lucid crash on heavy DB i/o (mvsas?) -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
