At the weekend there was a power-failure at our disaster-recovery-site. As everything should be connected to the UPS, this should not have had an impact… unfortunately the guys responsible for the cabling seem to have not provided enough power connections from the UPS. Result: one of our storage systems (all volumes in several RAID5 virtual disks) for the test systems lost power, 10 harddisks switched into failed state when the power was stable again (I was told there where several small power-failures that day). After telling the software to have a look at the drives again, all physical disks where accepted.
All volumes on one of the virtual disks where damaged (actually, one of the virtual disks was damaged) beyond repair and we had to recover from backup.
All ZFS based mountpoints on the good virtual disks did not show bad behavior (zfs clear + zfs scrub for those which showed checksum errors to make us feel better). For the UFS based ones… some caused a panic after reboot and we had to run fsck on them before trying a second boot.
We spend a lot more time to get UFS back online, than getting ZFS back online. After this experience it looks like our future Solaris 10u8 installs will be with root on ZFS (our workstations are already like this, but our servers are still at Solaris 10u6).
I started a wiki page about improving the soundsystem. The idea is similar to the wiki page about improving our linuxolator. It’s a way to tell the people what is currently available as patches (and where), what is broken and needs to be fixed, which improvements we like to see and so on. It’s maybe also a good place to list docs for soundchips. Currently the page about the soundsystem is a little bit low on content. I hope a lot of people contribute with ideas, facts, suggestions, pointers to helpful stuff, (pointers to) bugs, pointing out lack of docs and so on (either by modifying the page, or by mailing stuff to multimedia@FreeBSD.org).
With the linux page I was able to gain some momentum and several people are already helping with patches, running tests and so on (even little help matters). I hope the sound page will show a similar benefit.
So dear reader, do you play some music sometimes? Do you play an instrument which can be connected to some other stuff (MIDI)? Do you use acroread, skype, or some other linux software? If yes go to the wiki pages and read them please. When you’re finished please donate 5 – 10 minutes (I don’t mind if you sepnd more) of your time and try to tell us at multimedia@FreeBSD.org or emulation@FreeBSD.org about stuff you think could be listet there (instead of smoking a cigarette, argueing about bad behavior of people around you, or similar negative stuff). Thanks in advance and trust me, you will earn good karma when you do this!
