Hi, I have an external disk WD320 connected by USB to machine running FreeBSD 8.1-RELEASE i386 GENERIC. I need to use this disk for rsync backups. I tried to set label on existing filesystem, but label is still empty: Order of commands: root <at> kapo ~/# tune2fs -l /dev/da0s1 tune2fs 1.41.12 (17-May-2010) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: e17f87a5-8448-4518-b899-4e2ce2918354 Filesystem magic number: 0xEF53 . . root <at> kapo ~/# tune2fs -L usbWD320m5Sbkp1 /dev/da0s1 tune2fs 1.41.12 (17-May-2010) root <at> kapo ~/# tune2fs -l /dev/da0s1 tune2fs 1.41.12 (17-May-2010) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: e17f87a5-8448-4518-b899-4e2ce2918354 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal filetype sparse_super Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 39075840 Block count: 78142160 Reserved block count: 3907108 Free blocks: 11412001 Free inodes: 38767335 First block: 0 Block size: 4096 Fragment size: 4096 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 16384 Inode blocks per group: 512 Filesystem created: Tue May 23 15:24:24 2006 Last mount time: Sun Apr 29 23:09:04 2007 Last write time: Thu Oct 7 11:30:43 2010 Mount count: 21 Maximum mount count: 34 Last checked: Tue May 23 15:24:24 2006 Check interval: 15552000 (6 months) Next check after: Sun Nov 19 14:24:24 2006 Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group wheel) First inode: 11 Inode size: 128 Journal inode: 8 Default directory hash: tea Directory Hash Seed: 8ff346bb-24c2-4ea4-b07f-993fd3f21f61 As you can see, this is rather old disk formated on an old Linux machine (4 years ago). Is it a known bug, that label can't be set by tune2fs? I need to mount external disks by label instead of device name as the mount and backup will be scripted and I can't be sure what the device number (da0, da1, da2...) will be if somebody connect another disk device to this machine. Setting volume label with mke2fs works fine (on new disks), but I don't want to do it on this disk because it contains valuable data. Next strange thing is error message when I run `ls` command on /dev/ext2fs root <at> kapo ~/# ls -al /dev/ext2fs/ ls: : No such file or directory total 1 dr-xr-xr-x 3 root wheel 512 Oct 22 04:04 . dr-xr-xr-x 10 root wheel 512 Oct 22 06:04 .. As you can see, /dev/ext2fs exists. Plain `ls /dev/ext2fs/` is OK, but if I add '-l', it prints error "ls: : No such file or directory" Miroslav Lachman _______________________________________________ freebsd-fs <at> freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-fs To unsubscribe, send any mail to "freebsd-fs-unsubscribe <at> freebsd.org"
