After that I just rebooted the system and according to mount soft-updates were enabled. (I tried remounting / partition to RW w/o rebooting but mount showed soft-updates were disabled). I was rather satisfied that it is possible w/o making newfs, but today I the same actions didn't work on another system (almost the same hardware except MB). (I even tried them on the first one, but there everything still worked fine). On second system I got an error something like: /dev/ar0s1a: can't write superblock information (to my regret I can't remember exactly but I can repeat if necessary) Differences between system: I. 1) / partition is the first on disk (256 Mb) 2) FreeBSD-5.4-RELEASE-p8 (with patch fixing soft-updates' problem with inodes); link to patch http://kovalev.com.ru/softupdates-5.4R-p8.diff.txt 3) Custom kernel (i can provide kernel configuration if necessary) II. 1) / partition was the only partition on disk (approximately 65 Gb); there was also second 2 Gb swap partition 2) FreeBSD-6.0-RELEASE 3) GENERIC kernel Is there a possibility to enable soft-updates on large / partitions at all or there may be something else?
