New external HD, FS issue.

Jeebizz · 08-26-2006, 09:06 PM

I just got a new external HD

, I plan to use it for storage, and the filesystem I want to use is JFS. I formatted it to JFS, labeled Storage...

Code:

root@slacker:/home/slackuser# /sbin/mkfs.jfs -L Storage /dev/sdb1
/sbin/mkfs.jfs version 1.1.8, 03-May-2005
Warning!  All data on device /dev/sdb1 will be lost!

Continue? (Y/N) y
   \

Format completed successfully.

293033601 kilobytes total disk space.

I can mount it as a user, but I get this error when trying to write to it...

Code:

slackuser@slacker:~$ cd /mnt/hd
slackuser@slacker:/mnt/hd$ mkdir test
mkdir: cannot create directory `test': Permission denied

This is what I have for the device in fstab

Code:

/dev/sdb1   /mnt/hd     jfs    noauto,users,rw      0   0

Output from mount...

Code:

slackuser@slacker:~$ mount
/dev/hda2 on / type ext3 (rw)
proc on /proc type proc (rw)
/dev/hda1 on /ntfs type ntfs (ro,noexec,nosuid,nodev,umask=000)
/dev/hda4 on /fat32 type vfat (rw,noexec,nosuid,nodev,umask=000)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/shm type tmpfs (rw)
//SLACK/D on /mnt/network type smbfs (0)
/dev/sdb1 on /mnt/hd type jfs (rw,noexec,nosuid,nodev)

Any ideas?

can root write to the device?

Jeebizz · 08-26-2006, 10:40 PM

Yes it can, but I don't want to have to su to root just to be able to copy stuff to the drive.

One other note, I tried formatting it to ext2 or ext3 , but it was taking much longer, so I decided to format it under windows with partition magic to ext2, but then I noticed why it was taking so long. Partition Magic showed the used portion as 48GB

, I then formatted it to NTFS to see if it would take as long. Nope, it finished pretty quick, and the used portion was 72MB instead.....So thats why I chose JFS for linux instead, but I wouldn't mind using reiserfs, if I can get a window driver to be able to read/write to it natively. I have a ext2 driver for windows, it works great, but I don't want to sacrifice 48GB just for formatting the drive to ext2... Hrmm... Perhaps now would be a good time to change fs... I'm open to any suggestions.

if i were going format it as ext2 i'd use cfdisk.
You could try mounting your jfs drive with;

Code:

mount -tjfs /dev/sdb1 /mnt/hd fmask=777,dmask=777

if that works add

Code:

/dev/sdb1   /mnt/hd     jfs    noauto,users,rw,fmask=777,dmask=777      0   0

to you /etc/fstab

Jeebizz · 08-27-2006, 10:44 PM

That doesn't work...

Code:

slackuser@slacker:~$ mount -tjfs /dev/sda2 /mnt/hd2 fmaks=777,dmask=777
mount: only root can do that

By the way its sda2 now because sda1 is NTFS and I put all of my files on it for now, and so I created sda2 under cfdisk and formatted as jfs. Also, now I am getting a different error message when trying to even mount jfs.

Output from dmesg | tail

Code:

root@slacker:/home/slackuser# mount /dev/sda2

       missing codepage or other error

       dmesg | tail  or so

This is what I have now in fstab as well...

Code:

/dev/sda2        /mnt/hd2         jfs      noauto,users,rw,fmask=777,dmask=777 0  0

chrisortiz · 08-29-2006, 09:41 PM

try removing "fmask=777" from your fstab.

Jeebizz · 08-29-2006, 11:31 PM

Nope, still won't work.

Code:

slackuser@slacker:~$ mount /dev/sda2
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
       missing codepage or other error
       In some cases useful info is found in syslog - try

slackuser@slacker:~$ dmesg | tail

chrisortiz · 08-31-2006, 08:30 PM

i guess jfs doesn't respond to fmask and dmask, remove dmask=777 from your fstab, it should go back to your original error. The last thing i can think of is (as root):

Code:

chmod 777 /mnt/hd

Jeebizz · 08-31-2006, 09:00 PM

That last one works, lol.

Code:

root@slacker:/mnt$ chmod 777 hd2

Still I don't see why it is so troublesome just to be able to allow a normal user to write to a partition from a different disk. Oh well. Still thanks for the suggestion, at least it works.

[edit]

Well, here's another curiousity, I can copy, but whatever I copy is automatically set to readonly... Weird.

Code:

slackuser@slacker:/mnt/hd2$ ls -l

Linux was designed to be very secure. One deny inode can screw up alot of stuff. Its the same with NTFS based systems, they just aren't as secure out of the box.
