Good Morning all, I have been setting up a some cronjobs this week to do dumps. Currently my server is partitioned as such: Filesystem Size Used Avail Capacity Mounted on /dev/amrd0s1a 484M 95M 351M 21% / /dev/amrd0s1h 7.6G 2.5G 4.5G 36% /home /dev/amrd0s1g 992M 97M 816M 11% /mail /dev/amrd0s1e 4.7G 1.8G 2.6G 40% /usr /dev/amrd0s1f 14G 967M 12G 7% /var procfs 4.0K 4.0K 0B 100% /proc /dev/amrd0s1d 3.8G 576M 2.9G 16% /backup I am dumping "/var", "/usr", "/", and "/home" each Monday starting at 0200. They are being dumped into /home/bacup. (I then FTP them to a different local box). This morning I seen this in the logs, and, the dump was unsuccessfull. DUMP: Date of this level 0 dump: Mon Oct 28 02:20:03 2002 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/amrd0s1h (/home) to /home/backup/home.full_dump DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 2731756 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: 24.99% done, finished in 0:15 DUMP: 47.07% done, finished in 0:11 DUMP: DUMP: read error from /dev/amrd0s1h: Invalid argument: [block -835969890]: count=4096 read error from /dev/amrd0s1h: Invalid argument: [block -835969882]: count=4096 DUMP: DUMP: read error from /dev/amrd0s1h: Invalid DUMP: DUMP: read error from /dev/amrd0s1h: Invalid argument: [block -2055499334]: count=6144 read error from /dev/amrd0s1h: Invalid argument: [sector -1982468763]: count=512 argument: [sector -835969890]: count=512 ... ... DUMP: fopen on /dev/tty fails: Device not configured DUMP: The ENTIRE dump is aborted. and in my/var/log/messages and dmesg logs I get: dscheck(#amrd/0x20007): negative b_blkno -1982468757 I have been searching all morning (google, av etc) with no luck. It looks like these may be systems errors. Any Ideas? Also, one thing I have noticed in my searches, others that have seen this ALSO notice that they happened in the early morning hours (i.e. 0100 0200 0300 etc.) Is this just coinciudental, or is there some significance? Any thoughts would be appreciated. -Grant P.S. the other three file systems dumped no problem.
