Hi, my machine rebooted last night while doing a backup and formating a device. Ok, can happen, but the difference between an fsck useing the journal and a full fsck without using the journal surprises me a bit. While fsck with the journal showed no error, a full fsck came to this result: ** Phase 5 - Check Cyl groups FREE BLK COUNT(S) WRONG IN SUPERBLK SALVAGE? [yn] y SUMMARY INFORMATION BAD SALVAGE? [yn] y BLK(S) MISSING IN BIT MAPS SALVAGE? [yn] y uname -a says: FreeBSD X220.alogt.com 10.1-RC1 FreeBSD 10.1-RC1 #8 r272672: Tue Oct 7 14:35:32 WITA 2014 erich@X220.alogt.com:/usr/obj/usr/src/sys/X220 amd64 I did not realise any damage until just now when I found one file missing. This made me doing the fsckes. At the end, I also found the missing file under a different name in the proper directory. It could have been that the machine crashed while kate was trying to save this file and left it with the extention cppgh6857.new. It seems that nothing is missing from the file.
