Re: SCSi issues after 10.0 update



Hi guys,

(Adding a little more detail in case it helps:)

One approach would be:
1) find a test which always fails on netbsd-10 (maybe
pkgsrc/benchmarks/bonnie++ or similar)
2) boot a netbsd-9 install and confirm ir runs without issue
3) cross build of kernel from somewhere between
4) test boot the new kernel with the netbsd-9 install, and loop back
to 3) either closer to netbsd-9 or netbsd-10

I'm happy to help with 3) if you don't have a particularly fast build
box - I can run up a set of test kernels (say one per month between -9
and -10) and you can binary search across them

thanks for the proposals... however I fail at 1) !
I tried doing again the same thing: sharing over NFS with other boxen building and compiling heavy stuff on the same system - it stayed up for several days.

Then I thought of stress-testing. I launched bonnie++ several times on on edisk, on the other and then launched two instances in parallel on both disks, repeatedly.
No problems!

I really wonder what happened the first time... what error it was? For sure the system acceptable stable. Also, this way, I cannot say 9.3 was unaffected.. albeit in A year or so I never had to reboot forcibly the system it was very stable.

I suppose that the disks aren't in a too bad shape and all seems stable even with torturing, bonnie writes gigabytes and thousands of files.

The only thing that bonnie doesn't dest is concurrency with other devices - eg. high network activity with concurrent high disk activity.

I could try running bonnie++ over NFS??
