Hi, I have this ZFS server up for about 27 days, and about 3 weeks ago (was not really paying attention) it turns out it lost its SSD that I'm using for log and cache. There is also a poor and lonely memory stick for log. So the box did not really suffer file loss. system is running: FreeBSD zfs.digiware.nl 8.2-STABLE FreeBSD 8.2-STABLE #58: Thu Nov 17 09:43:46 CET 2011 root@zfs.digiware.nl:/home/obj/usr/src/src8/src/sys/ZFS amd64 more info like dmesg, pciconf, kernconf, zpool iostat at: http://www.tegenbosch28.nl/FreeBSD/systems/ZFS/ But it is weird to just lose a SSD from the bus. And it has happened before. And you can see that AHCI really banged on the frontdoor... The device is a Corsair 60Gb Force GT. And thusfar I have not found any suggestions that that serie of devices is prone to doing this. It was a real dead device, the only way to get it back: powercycle the device by pulling it, and stick it back then camcontrol rescan I've now upgrade it to a 120Gb Corsair, to see if that has the same problem. Other FreeBSD-ers have like problems?
