:> 1. I had i386 system with two 20GB IBM ATA disks and 5.0-current system :> built from March 31 sources. First I used striping over two disks and :> put /usr filesystem onto it, did overnight testing and all was well. :> 2. Same system, same sources plus two same disks. Now I tried raid5 over :> four disks and failed to extract pax archive, got deadlock, not panic. :> 3. Same system, downgraded to 4.0-RELEASE. Raid5 over four disks and I :> failed to extract pax archive, got panic. :> No softupdates. : :Same story here, but using softupdates or async mounts I can reproduce :the hang or panic in less than 60 secs.. : :Vinum with raid5 is plain broken, include INVARIANTS in the kernel :and see why... : :-Søren Hang on to that thought. As soon as this struct buf mess gets cleared up if Greg hasn't figured out where the bug is I'll throw my lot in to try to speed-up locating and fixing the problem. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
