I am trying to set up labels on a USB HD so that I can mount it in the
same place each time I connect it.
The short version is that from what I've done (which I will detail
below) when I try to
$ sudo mount /dev/ufs/Back1s1 /Volumes/Back1
mount: /dev/ufs/Back1s1 : Invalid argument
While
$ sudo mount /dev/da4s1 /Volumes/Back1
does work.
Using the latter defeats the purpose however, since I want eventually
to mount things to a different mount point depending on their label.
Here is more detail of what I've done so far. I'm running RELENG_7_0
One thing that I've noticed is that /dev/da4s1 and /dev/ufs/Back1s1
have different device numbers:
ls -l /dev/da4* /dev/ufs
crw-r----- 1 root operator 0, 121 Apr 10 03:57 /dev/da4
crw-r----- 1 root operator 0, 122 Apr 10 03:57 /dev/da4s1
/dev/ufs:
total 0
crw-r----- 1 root operator 0, 123 Apr 10 03:57 Back1
crw-r----- 1 root operator 0, 124 Apr 10 03:57 Back1s1
But that might not mean anything.
I first used fdisk to change the active slice to be of FreeBSD type
(I'm not planning on using these disks for other systems.) Here is
what fdisk currently reports
$ fdisk /dev/da4
******* Working on device /dev/da4 *******
parameters extracted from in-core disklabel are:
cylinders=9729 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=9729 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 16065, size 156280320 (76308 Meg), flag 80 (active)
beg: cyl 1/ head 0/ sector 1;
end: cyl 512/ head 254/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
I also used glabel to try to get a label on it, but couldn't see how I
could use the glabel information for mounting.
here is what glabel reports for the device
$ glabel dump /dev/da4s1
Metadata on /dev/da4s1:
Magic string: GEOM::LABEL
Metadata version: 2
Label: Backup 1
So not knowing how to use the glabel information for mounting I used
the -L option to newfs when I created the USF2 filesystem on /dev/da4s1
$ tunefs -p /dev/da4s1
tunefs: ACLs: (-a) disabled
tunefs: MAC multilabel: (-l) disabled
tunefs: soft updates: (-n) disabled
tunefs: gjournal: (-J) disabled
tunefs: maximum blocks per file in a cylinder group: (-e) 2048
tunefs: average file size: (-f) 16384
tunefs: average number of files in a directory: (-s) 64
tunefs: minimum percentage of free space: (-m) 8%
tunefs: optimization preference: (-o) time
tunefs: volume label: (-L) Back1
[jeffrey@kreacher /dev/ufs]$
(oops, I probably should turn on ACLs for this, but that is another
matter).
Any pointers to help in getting this slice mountable in the same place
every time. I feel like I must be very close to how this should be
done, but something is a bit off.
Cheers,
-j
