This has been covered so many times it makes my carpal tunnel ache just to think about typing stuff about it again. Briefly, the system reserves a portion - 8% by default - on a file system to deal with possibilities of needing cleanup and operating space if a file system fills up. The per cent is settable, but 8 has worked well and has become the default. ////jerry > > I have run fsck -fy on the partition while it was unmounted; no effect. > I've CTRL-C'd another fsck which marked the partition dirty, rebooted, and > let fsck do it's own thing; no effect. > > What do I need to do to fix this inconsistency? > > > Cheers > > > -- > Adam Smith > Internode : http://www.internode.on.net > Phone : (08) 8228 2999 > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
