I couldn't reproduce this yet in a KVM test environment with if=ide, having run lots of package builds, a 'make universe' of all FreeBSD and some other disk benchmarks to try to stress it. I'm just curious what qemu-kvm version is used on falla's KVM host? As 1.1.2+dfsg-6+deb7u8 in wheezy had some issues. I think we should rather be using if=virtio now anyway. Could we try to switch falla to that, and hopefully the issue might go away? The procedure for that is outlined at https://bugs.debian.org/787136#20 though I suggest we may rather want to use diskids in /etc/fstab, making it easy to switch back if needed. And while here, I recommend enabling soft updates journalling, on any UFS partition except / and /boot, as we do for new installs now. It can only be changed while partitions are unmounted, with: # tunefs.ufs -j enable /dev/foo And set up as much logging as possible to the serial console (boot with kernel flags -D -h, /etc/grub.d/10_kfreebsd), in case Ganeti can keep logs of that, as it should help for issues like this.
