Hi, all,
while most cheap servers with SATA disks are not really hot-plug
capable, changing a failed disk (either gmirror or zfs) was possible
without a reboot by executing e.g. if ad4 failed:
atacontrol detach ata2
change disks
atacontrol attach ata2
What is the proper equivalent for ahci,

None is needed: yank the disk, reinsert, wait a few seconds, done.

Yes - my fault. I had an active swap partition on the disk which perfectly
explains the panic.
I replaced that one with a gmirror device, now.
You might try booting RELENG_9 (which has ahci.ko as the default, so no
need to mess about) on

I don't remember what our specific problem at $WORK was, perhaps it

Hi Jeremy,
This is not hardware problem, I've already checked that. I also ran fsck
today and got no errors.
After some more exploration of how mongodb works, I found that then
listing hangs, one of mongodb thread is in biowr state for a long
time. It periodically calls msync(MS_SYNC)

I'm not on the Release Engineering Team, and in fact don't have a src
commit bit ... but this close to a major release, no, it's too late to
