Soft-updates will do that if the system crashes in the middle of writes. Sounds to me like you need to address your hardware or environmental problems. If your system is needing hard-booted that often, you'll benefit from fixing the cause of the hard-booting more than from a journalling fs. > My collegues ask me why i don't use a journalling file system, but > FreeBSD doesn't seem to provide any. Collegues are like that. No matter what you do, they'll ask why you didn't do the thing that they think will save the day. The journalling fs issue seems to come up on this list every few months. Search the archives and you'll find a lot of information on it compared to soft updates. > Is there any way to speed up the fsck? 20 minutes really is too long! FreeBSD 5.0 has background fsck, which seems to work very well in the limited tests I've done. fscking doesn't interrupt the boot process at all. However, 5.0 isn't considered production quality yet, so you can only really consider it for the near future. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
