Hi Yes, I followed the thread, but to my understanding it was not conclusive that ccd would be such a great risk - there were at least two diverging opinions. I tried mounting the device with softdep, which yielded 7 MB/s write throughput - better, but not overwhelming. That said, I then tried to simulate a crash (hit power putton on idle box, no obvious write activity going on on the device) - and the filesystem came back with unrecoverable errors. I will try to investigate this further and determine if it was just bad fs luck or the underlying ccd device. Anyway, I wanted to avoid building a custom kernel, so I might just rsync the two disks from cron. krgds /markus
