I'll make the assumption that the 'df' output is complete (ie there isn't another filesystem mounted over part of /var) and neither figure is misleading (ie there isn't whitespace in either name and no chrooting or jails are in use). The remaining possibilities are: a) A running process has an unlinked file open. The space will be released when the process closes the file. b) Filesystem snapshots exist. Use snapinfo(8) to check and "rm" them if appropriate c) A combination of UFS and/or fsck bugs and system crashes have lost space. Shutdown or reboot to single user mode and explicity fsck /var. Since you have already bounced the server, it is unlikely to be option a (unless the same process has just grabbed the space again). --=20 Peter Jeremy --gatW/ieO32f1wygP Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGQFM8/opHv/APuIcRAoZnAKCn6NF8kJrCMppcDpQGiT2kKandWgCgnqsa 5UmE6YbhkciaFaqKdqdfUac= =wB41 -----END PGP SIGNATURE----- --gatW/ieO32f1wygP--
