Looks as if CONFIG_DEVFS_FS=y was the problem (hmm, wonder where _that_ crap got into my config ?) - a look at my logs suggests that the date/time were somewhat random with it set, but mostly not far enough adrift to force an fsck (e.g. my last duff kernel booted up about 29.5 hours slow). Possibly, something introduced in the 2.6.12 series has broken it, or perhaps it's always been a bit random, but since devfs is going away whenever linus picks up the patches, there isn't a lot of point looking more deeply at it.

date wrong when ext3 fs mounted, 2.6.12-rc kernels
Hi, this isn't specifically a debian issue. I've been running 2.6.12-rc6 on an iBook G4 for a week or so, and it's recently started to fsck /home on boot because it hasn't been checked for an unfeasibly large number of days. Fortunately, I think I've now got pbbuttonsd tamed, so I'm not having to poweroff/boot very often now. Last night I booted, and after I'd logged in I looked at dumpe2fs for the /home fs - although I'd only just mounted it, the 'last mount time' was Mon Aug 22 02:33:35 2005 instead of the expected Wed Jun 15 23:45:00 2005 or thereabouts. By the time I logged in, ntp had corrected the date.

Will I be able to reformat my Deb install to ext3 later? Thanks. --Harvey Yes, all you need to do is rune 'tune2fs -j /dev/hdaN' to add journalling to an existing partition. Then you simply change the entry in /etc/fstab to be ext3. No repartitioning needed. Cheers, jas.

Re: Ext3 fs
Interesting that you should mention this, Harvey, as I was just looking through some ext3 documentation today. By far the best rundown on the features and tweaks of ext3 is Andrew Morton's, at http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html Furthermore, Daniel Robbins has a couple of articles on the filesystem at IBM developerWorks - http://www-106.ibm.com/developerworks/linux/library/l-fs7/ and http://www-106.ibm.com/developerworks/linux/library/l-fs8/ Basically, ensure you have a ext3-capable kernel and current versions of util-linux and e2fsprogs, then you can tune2fs -j /dev/hdXX which will non-destructively convert your ext2 filesystem to ext3 Edit your /etc/fstab and replace any instance of 'ext2' for the partition you have tuned with 'ext3', reboot and you're away! If you want to disable the periodic fsck of your ext3 partition, simply tune2fs -i 0 -c 0 /dev/hdxx Hope that helps!
