Kinda, see this thread:=20 http://lists.freebsd.org/pipermail/freebsd-current/2004-November/043670.html =46rom all of my experience, you can consider this filesystem busted. Try t= o get=20 as much data off it as you can (chances are some files are so corrupt that= =20 you'll get a hang when you try to copy them) and take care to preserve file= =20 modes & permissions, then newfs and restore. It's kinda sad, but right now soft-updates must probably be considered unsa= fe=20 for some configurations. The reliability in the case of crashes is about ju= st=20 as bad as mounting something async... my guess is that it's not really a ne= w=20 bug in softupdates, but rather effects from modern big ata drives with big= =20 caches and write caching enabled (and no tagged queueing - although IIRC th= e=20 ata tags support is disabled in 5.x and -CURRENT anyway). =2D-=20 ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org --nextPart3303380.WnA52cocnN Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBBvB7/Xhc68WspdLARAkuYAJkB4e7vQDHreSABU2bzuErjCT4u3wCglIIT H2XMK0GIR6WUVYSTB9PJmpY= =OmJf -----END PGP SIGNATURE----- --nextPart3303380.WnA52cocnN--
