Cannot get two JFS partitions mounted, fstab.

**killabee44** · May 12th, 2014

Hi all,

I have a mythbuntu install in which I am trying to get two JFS partitions mounted. Im sure the problem lies in the fstab file, but I have tried multiple options, but cannot get them mounted. Your help will be appreciated!

Here is some info:

sudo blkid

Code:

/dev/sda1: UUID="569c202e-fbc1-4d7b-9070-47c5ae4c5056" TYPE="ext4" 
/dev/sda3: UUID="2dfd438b-957d-403c-99c7-95fd6b44726c" TYPE="ext4" 
/dev/sda5: UUID="ec39da7c-894d-436f-879e-6ebdc6b1cf4d" TYPE="jfs" 
/dev/sdb1: LABEL="mythtv" UUID="7ce01738-5525-4afe-bd89-0af7e1fd969d" TYPE="jfs"

/etc/fstab:

Code:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=569c202e-fbc1-4d7b-9070-47c5ae4c5056 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda3 during installation
UUID=2dfd438b-957d-403c-99c7-95fd6b44726c /home           ext4    defaults        0       2

#JFS MEDIA:
UUID=ec39da7c-894d-436f-879e-6ebdc6b1cf4d    none         jfs     defaults,noauto,rw,user     2
UUID=7ce01738-5525-4afe-bd89-0af7e1fd969d    none         jfs    defaults,noauto,rw,user     2

I have tried using the auto option in fstab but end up with an error during boot that says "cannot mount, press s to skip" on both partitions.

Thanks in advance!

Your missing parameters. You need to specify a mount point, and a dump number. Here is a generic layout using the some of your info:

Code:

UUID=7ce01738-5525-4afe-bd89-0af7e1fd969d /mnt/share jfs defaults,users,noauto 0 2

That will mount the specified device at /mnt/share with jfs as the FS and take the default options (rw, suid, dev, exec, auto, nouser, and async) with 0 for dump and 2 for pass. You will obviously need to create the mount point (/mnt/share in my example) before you try to mount it.

Here is Ubuntu's help page for fstab:

Thanks for your reply..

I tried with your settings and did not get errors at startup. So that is good.

Im not sure how to create the shares, so I opened up a file browser (thunar) with sudo and created the two folders in /mnt. I then changed the owner to users and permissions to r/w. When I click the folders I cannot see my files though, so Im sure that is not correct.

When I have the file browser logged as sudo, I can see the drive on the left side, but when I try to access it I get the following error:

Code:

mount: wrong fs type, bad option, bad superblock on /dev/sda5,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

This is the way my fstab file looks now:

Code:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

You cannot have the files in the directory before you mount the drive. So if you have /mnt/music in an un-mounted stage and place files in the directory, when you mount the device to that directory, those files will not be there until you un-mount the device.

Also, you have the option noauto so the lines that you have added to fstab will not mount at boot, you will have to manually type out the mount command for each single line.

Would you also post the output of:

Code:

dmesg | tail
and
ls -ll /mnt

Let's make sure that those partitions are actaully JFS, type:

Code:

sudo fdisk -l
and
sudo fsck -N /dev/sdb1
and
sudo fsck -N /dev/sda5

Also,

Also, try and just mount the device from the terminal and see what happens, try:

Code:

sudo mount -t jfs -o noauto,user,defaults /dev/sdb1 /mnt/mythfiles

We will work on the sharing bit next, we first need to get them mounted Ha!

Tfrue,

What I meant is that the drive (and the other paritition I am trying to mount) both have data on them, so I am just talking about accessing that data.

Here are the outputs:

Hmm, so does that mean that those are not seen as JFS partitions? I looked on Gparted just now and it does show them as being JFS, but it said that I needed the software package jfsutils in order to see details. I loaded that package and am rebooting.

Edit:

Ok, after installing jfsutils, I get:

sudo fsck -N /dev/sdb1

Code:

fsck from util-linux 2.20.1
[/sbin/fsck.jfs (1) -- /mnt/mythfiles] fsck.jfs /dev/sdb1

sudo fsck -N /dev/sda5

Code:

fsck from util-linux 2.20.1
[/sbin/fsck.jfs (1) -- /mnt/music] fsck.jfs /dev/sda5

I still can't mount via the command line with the same error I posted above.

Edit again..

Ok, after doing: sudo fsck.jfs /dev/sda5 and sudo fsck.jfs /dev/sdb1 I am now able to mount and see my files, but only as sudo. I went ahead and edited my fstab to automount.

After reboot, sda5 and sdb1 automounted, but I can only see the drives when I run Thunar as sudo.

I then changed fstab again since I realize that I wrote users instead of the user option by mistake. That allowed me to see and edit the files in those mounts with a non sudo username.

The mounts still don't show up under devices, but at least I can create a shortcut in Thunar for the mount points.

The fdisk command showed that you have a file system type of 83 which is the Linux ext file system. So what I would do now is just to try and mount with mount auto detecting the FS and mount under the /media directory. So first unmount and at least comment out the new lines you added regarding these two partitions by adding a # (hast-tag) infront of each new statement and save the file. You can issue mount to see if you still have the two partitions (/dev/sda5 and /dev/sdb1) mounted.

So, type:

Code:

sudo mkdir /media/mythtv
sudo mount -t auto /dev/sda5 /media/mythtv

That will create the mythtv directory under /media and then we'll tell mount to auto detect the FS type of /dev/sda5 and mount it at /media/mythtv. You can now type mount to see if it mounted it.

You should also make another directory under /media for the /dev/sdb1 partition and name the new directory anything you want and use the same syntax as before to mount /dev/sdb1 on the new directory. (e.x. sudo mount -t auto /dev/sdb1 /media/newDirectory)

So after all this, I would like to see some output, lol. Please type:

Code:

mount
and
sudo fdisk -l
and
sudo blkid
and
ls -ll /media
and
cat /etc/fstab

Thanks,
Chris

I also meant to mention that you may have to change the ownership of the two new directories /media/mythtv and the other one you should've made for /dev/sdb1;So first make sure that they are mounted because if they are not the permissions you set for them now will not stay when you do mount to them,so you will need to type(I'm using tfrue but you will need to use your username):

Code:

sudo chown tfrue.tfrue /media/mythtv
and
sudo chown tfrue.tfrue /media/newDirectory (For the /dev/sdb1 directory)

Ok, I did as you said and commented out the two lines in my fstab. I then manually mounted them using the command you gave me.

So, it looks like they are seen as JFS, no? I still don't understand why fdisk sees them as type 83 linux..

Edit: after looking around it seems that type 83 linux can be various filesystem types including JFS.

Ok, I got the permissions. But, will the mythtv service still be able to access the /media/mythfiles with me as the owner?

Thanks.

**tfrue** · May 16th, 2014

While reading through a MythTV article, it seems as though we will need the permissions to be owned by mythtv user and group and then add your user account to the mythtv group.

So lets try again, type:

Code:

sudo chown mythtv.mythtv /media/mythtvfiles
and
sudo chown mythtv.mythtv /media/newDirectory (For the /dev/sdb1 directory)
and
sudo useradd -G mythtv YourUserName (Which will add you to the mythtv group)

Were you succesfully able to mount and view the files by manually mounting? If so, I would say it would be safe to remove the comments you made on the /etc/fstab as I reviewed them and they seemed to be a proper mount syntax
