RE: Dump snapshot issue...
Is /home really a separate file system on your system? Or is it just a directory in another filesystem? df -h output: Filesystem SizeUsed Avail Capacity Mounted on /dev/da0s1a3.9G351M3.2G10%/ devfs 1.0K1.0K 0B 100%/dev /dev/da0s1g 98G 13G 77G14%/home /dev/da0s1d7.7G136K7.1G 0%/tmp /dev/da0s1e9.7G5.6G3.3G63%/usr /dev/da0s1f9.7G1.3G7.6G15%/var /dev/da1s1d133G 40G 82G33%/backup devfs 1.0K1.0K 0B 100%/var/named/dev procfs 4.0K4.0K 0B 100%/proc Marci ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
RE: Dump snapshot issue...
One thing you should try is to remove the dump_snapshot files, because they are supposed to be unlinked when the dump starts anyway, so they shouldn't be sticking around. Also, look for file flags on the directories, or ACLs, etc. And consider the permissions you're running dump with. Dump is running as root via cron / initiated by hand. ACLs not used. Have removed all existing dump_snapshot files, and have also removed and recreated all .snap directories. S'now working fine for all mountpoints, except /home... mksnap_ffs: Cannot create /home/.snap/dump_snapshot: Input/output error dump: Cannot create /home/.snap/dump_snapshot: No such file or directory It doesn't appear to proceed as normal either... as you can see below, it ends the previous dump, starts the /home dump, gets an I/O error, then proceeds straight to the /usr dump. The /home dump never gets performed. If I remove the -L option, everything goes thru fine, but complains about lack of -L flag... DUMP: DUMP IS DONE mksnap_ffs: Cannot create /home/.snap/dump_snapshot: Input/output error dump: Cannot create /home/.snap/dump_snapshot: No such file or directory DUMP: Date of this level 0 dump: Wed May 6 08:30:31 2009 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping snapshot of /dev/da0s1e (/usr) to standard output Fsck finds no errors on /home... point to note... mksnap_ffs CAN create /home/.snap/dump_snapshot as I'm sat looking at the file, however, once it's created it it's as tho it can't access it. The file is there, it wasn't before I ran the script. It's created it as root:operator, perms 400. I can open it in pico, add content to it, and save it happily. So I'm baffled!

Dump snapshot issue...
I've got a script that dumps various filesystems to tape for me, but I've always had an issue whenever I've used the -L option... see below: /usr/bin/mt rewind /sbin/dump 0aLuf /dev/sa0 / dump: Cannot create //.snap/dump_snapshot: No such file or directory /sbin/dump 0aLuf /dev/sa0 /home mksnap_ffs: Cannot create /home/.snap/dump_snapshot: Input/output error dump: Cannot create /home/.snap/dump_snapshot: No such file or directory /sbin/dump 0aLuf /dev/sa0 /tmp dump: Cannot create /tmp/.snap/dump_snapshot: No such file or directory /sbin/dump 0aLuf /dev/sa0 /usr dump: Cannot create /usr/.snap/dump_snapshot: No such file or directory /sbin/dump 0aLuf /dev/sa0 /var dump: Cannot create /var/.snap/dump_snapshot: No such file or directory /usr/bin/mt rewind The .snap folders exist at all points, are set to root:operator, with perms 770... The dump_snapshot files seem to be present, albeit 0 bytes, root:operator, perms 400... Running 7.0-RELEASE-p11... Any suggestions?

From the dump(8) man page: If the .snap directory does not exist in the root of the file system being dumped, a warning will be issued and the dump will revert to the standard behavior. This problem can be corrected by creating a .snap directory in the root of the file system to be dumped; its owner should be ``root'', its group should be ``operator'', and its mode should be ``0770''.
