mount ntfs by LABEL

oso_togari · 05-22-2009, 06:37 AM

Hi all

i want to mount by label an ntfs volume.
I have installed in a RHEL4 this packges:
[root@la_machina~]# rpm -qa | grep -i NTFS
ntfsprogs-1.9.4-1.2.el4.rf
ntfsprogs-devel-1.9.4-1.2.el4.rf
kernel-module-ntfs-2.6.9-67.0.7.ELsmp-2.1.20-0.rr.10.0

then i labeled a ntfs volume:
[root@la_machina~]# ntfslabel /dev/sdd1 backup_exchange
[root@la_machina~]# ntfslabel /dev/sdd1
backup_exchange

BUT, how can i mount by label??

[root@la_machina~]# mount LABEL=backup_exchange /backup/exchange/
mount: no se ha encontrado esta particiÃ³n

ntfs commands:
[root@la_machina~]# ntfs
ntfscat ntfsclone ntfscluster ntfsfix ntfsinfo ntfslabel ntfsls ntfsresize ntfsundelete

mount commands:
[root@la_machina~]# mount
mount mount.cifs mount.smb mount.smbfs

Thx in advance

You could look at "mount --help". Use the "-L label" argument to mount by label.

Thx, but same thing:

[root@la_machina~]# mount -l LABEL=backup_exchange /backup/exchange/
mount: no se ha encontrado esta particiÃ³n
[root@la_machina~]# mount -L backup_exchange /backup/exchange/
mount: no se ha encontrado esta particiÃ³n
[root@la_machina~]# mount -L LABEL=backup_exchange /backup/exchange/
mount: no se ha encontrado esta particiÃ³n

I don't understand the language of your error message. Could you translate it. Does RHEL support mounting by label or UUID? Or do you not have NTFS support. Look in the manpages for mount and mount.ntfs for the answer. On my system, you can use -L label or -U UUID. But mounting by label may be a more recent innovation.

Hi

the error messagges says: "mount: partition not found"

Im able to mount this ntfs partition by device: "mount /dev/sdd1 /backup/exchange" -OK
And im able to mount by LABEL all my ext3 partitions, but maybe the system dont recognize properly the ntfslabels...

First, does the ntfsprogs provide you with the ntfs-3g driver? You really need to use it and not the old kernel module, especially if you need write ability.

Next, does the drive show up in the "/dev/disk/by-label" directory? udev should create a link to your device there, named by label. If it exists you can use that link to mount the device instead of the using LABEL flag.

Hi...

I dont have download/installed ntfs-3g,(i dont need write access)

i only installed the ntfsprogs(to get the command i need=ntfslabel) and the kernel-module-ntfs, because i think it's enough
to manage ntfs partitions

So, you confirm me that i need ntfs-3g to mount by LABEL?

Another thing...in /dev/disk/ i only have by-path...and i dont know why?¿?¿?

[root@la_machina~disk]# pwd
/dev/disk
[root@la_machina~disk]# ls
by-path
[root@la_machina~disk]# cd by-path/
[root@la_machina~by-path]# ls -la

Does RHEL4 use udev? If so, it looks like your distro doesn't have the rules to create the /dev/disk/by-label symbolic links.
You could mount by ID instead or create the rules needed in /etc/udev/rules.d/ to create them.

Look at your mount manpage. I don't know if your version of mount (or mount.ntfs) will mount using LABEL= instead of the device node.

---

P.S. Looking through the 70-kpartx.rules file, I see were disk/by-id is created but not disk/by-label. I looked further and found that the /dev/disk/by-label links on my system (openSUSE) is created by a udev rule in the /lib/udev/rules.d/60-persistent-storage.rules file of my initrd file.

Code:

# probe filesystem metadata of disks
KERNEL!="sr*", IMPORT{program}="vol_id --export $tempnode"

# by-label/by-uuid links (filesystem metadata)
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*", SYMLINK+="disk/by-uuid/$env{ID_FS_UUID_ENC}"
ENV{ID_FS_USAGE}=="filesystem|other", ENV{ID_FS_LABEL_ENC}=="?*", SYMLINK+="disk/by-label/$env{ID_FS_LABEL_ENC}"

LABEL="persistent_storage_end"

You could try adding the disk/by-label line in the appropriate location. Probably by inserting the line in the udev.d rule that creates your disk/by-id rule. But you may need to add a line to your initrd's init script to create the /dev/disk/by-label/ directory if it doesn't exist.

I use RCS to save my old config files before making changes (i.e. sudo ci -l /etc/X11/xorg.conf to backup xorg.conf). That way I can check out the old version if there is a problem. It also provides a way to store notes with each version where you can include reminders what changes you made. RCS is old but light weight & very handy for simple config file versioning.
