Sata drive not mounted

[ExTruckie]

I reinstalled 10.04.03 and not I cannot mount my sata drive. These are the errors I get in addition to one at boot stating that "cannot mount media/Stuff" press S to skip or M for manual recovery.

I hit skip and boot onto the desktop and try to mount the volume there and I get the errors attached below

What am I do to next? I don't want to reinstall again!!

[Hakunka-Matata]

did you use a different user name with the new install? I'd try navigating there using the Terminal, check permissions on the folder???

Here is a bit of additional, I can see the drive in mountmanager I am not able to mount it.
If I go there in terminal I can see the folder I just cannot access it.

[coffeecat]

In your second post, your terminal screenshot shows that you are trying to cd to the folder "stuff" whereas in your first post you report "cannot mount media/Stuff". Linux is case-sensitive.

Anyway, you are using one of the third-party mount applications - mountmanager. I don't know about that one but there are some in the repository that cause more problems than they solve. Let's do some investigating. Please post the output of these terminal commands:


cat /etc/fstab
ls -l /media/
sudo fdisk -lu
ls -l /etc/udev/rules.d/
mount

Please don't post these are screenshots. Highlight the terminal output with the mouse, right-click and "copy". Now paste it into your post, but between
and tags, so that when you post this:


Your

It is appears like this:

Ok
My bad on the terminal. I never had any trouble with mount manager and it is under the Software Center. It was added in 10.04.

Here is the output from the commands you gave me.

Ok I see that the OS is seeing the drive and folders but cannot mount them.
Also the mount command only seems to bring back a response from sda1 and I am having trouble with sdb1.


One other thing. I noticed when I was installing the OS the installer asked under the advanced button where I wanted to put the boot manager. Default was on sdb and I wanted to have the bootloader on sda.
This caused several failed installs because I do not have the sata drive listed as a boot drive in the BIOS, and was not changing it.

Thanks

Here is the output from the commands you gave me.
mark@Fileserver:~$ cd /media
mark@Fileserver:/media$ cd /Stuff
bash: cd: /Stuff: No such file or directory
mark@Fileserver:~$ clear

Your "cd /Stuff" syntax is wrong. You're trying to cd into a folder called Stuff in the root of the filesystem. Since you've already cd'd into /media, you should use one of these:


cd Stuff

or


cd ./Stuff

Next - you didn't take notice of what I said about code tags. Compare:

Without code tags, the output loses its formatting and is near unreadable.

The output of the mount command shows nothing mounted on /media/Stuff even though there is a line in /etc/fstab for this. My guess is the UUID is wrong. I forgot to ask you to post the output of blkid, so please post this output (in code tags):


sudo blkid

Then, hopefully, we'll have all the information needed to see why nothing is mounted on /media/Stuff.

[ExTruckie]

Just about the time I was notified of your posting. I made a discovery that has some bearing on the problem. I have two (2) /media/Stuff folders. One on sda1 and the other is on sdb1. The sda1 is the only one that is active.The one on sdb1 is, I believe, is causing the problem and I can't seem to remove it.

Here is the output of the code you asked for, sorry I forgot to close the code box

This is a bit of a mystery. The UUIDs in your blkid output match up with the UUIDs in your /etc/fstab, so your "Stuff" partition should be being mounted OK.

Your second fdisk output shows what was sda as sdb and vice versa. This happens sometimes with some BIOSs and is of little consequence. This is why UUIDs are used in /etc/fstab. You don't have two partitions labelled stuff. By the way, I think you are getting mixed up between folders and partitions:


I have two (2) /media/Stuff folders. One on sda1 and the other is on sdb1.

"/media/Stuff" is the mountpoint (which is a folder) in your main filesystem. It is in partition 1 of your 40GB drive. The Stuff partition is partition 1 in the 320GB drive.

I'll come back to this when I'm fresh in the morning. At the moment I can't see what you need to do and why you're getting the error message that you posted originally.

[ExTruckie]

ok I just realized where your at. Ok I'll look for your reply in the morning.

Good nite.

[ExTruckie]

Just so you have everything in the correct format, I reran all the terminal commands. and posted them here.
I hope this helps.

In your post #7 you made this comment:


Just about the time I was notified of your posting. I made a discovery that has some bearing on the problem. I have two (2) /media/Stuff folders.

Which is why I thought you were confusing folders and partitions. But now it seems that I am trying to hit a moving target.

In your post #5:

drwxr-xr-x 2 root root 4096 2011-08-29 00:22 Stuff

But in your most recent post #11:



mark@Fileserver:~$ ls -l /media/
total 12
lrwxrwxrwx 1 root root 7 2011-08-28 22:44 floppy -> floppy0

drwxr-xr-x 2 root root 4096 2011-08-29 00:22 Stuff

The /media/More Stuff folder was not there yesterday. How did you add it? With mountmanager? As an aside, it has a space in the folder name which is a very bad idea for a mountpoint.

More worryingly, the reason I asked you for this (from your post #5):


mark@Fileserver:~$ ls -l /etc/udev/rules.d/
total 12
-rw-r--r-- 1 root root 727 2011-08-28 22:58 70-persistent-cd.rules

-rw-r--r-- 1 root root 1157 2010-04-19 05:30 README

... was to see if mountmanager had created custom udev rules for mounting your "Stuff" partition, which would have complicated things. On the evidence of the above, I could see that it had not, which is why I did not comment on that output. But now I see this (in your post #11):


mark@Fileserver:~$ ls -l /etc/udev/rules.d/
total 12
-rw-r--r-- 1 root root 727 2011-08-28 22:58 70-persistent-cd.rules

lrwxrwxrwx 1 root root 13 2011-08-29 16:56 z80_user.rules -> ../user.rules

How did z80_user.rules get there? You must have done something.

Anyway, I think the remount option in the /etc/fstab line for /media/Stuff may be a problem. Try this. From a terminal:


gksudo gedit /etc/fstab

You will see this in the gedit text editor:


/dev/fd0 /media/floppy0 vfat noauto 0 0
UUID=3c64c76a-5c12-481d-952b-4c3b105e4454 /media/Stuff ext3 remount,users 0 0
UUID=0f56150f-0984-45a7-ac7d-9b3948e5d777 / ext4 defaults 0 0
UUID=50378997-de74-46f7-b153-e9d166d057d6 / swap sw 0 0

Be very careful. If you make an error editing this file you have the potential to make your system unbootable. Now edit the file so that it looks like this:


/dev/fd0 /media/floppy0 vfat noauto 0 0
UUID=3c64c76a-5c12-481d-952b-4c3b105e4454 /media/Stuff ext3 defaults,users 0 0

UUID=50378997-de74-46f7-b153-e9d166d057d6 / swap sw 0 0

There is only one word to change: remount -> defaults. And I've highlighted them in red to make it plain for you. Save the edited file and close gedit. Now:


sudo umount /media/Stuff
sudo mount -a

If you get any errors, simply reboot. Does that help?

[ExTruckie]

I got your post. I will do the things you ask later as I must be off to work.
I uninstalled mountmanager since we started and I used PySDM to create the Mount Stuff.

I was trying to fix the problem on my own. I cannot remove the More Stuff either

Thanks for all your help so far and I hope my poking around didn't muck things up.

[coffeecat]

I uninstalled mountmanager since we started and I used PySDM to create the Mount Stuff.

Aaaarrgghhh! Out of the frying pan; into the fire. :(

EDIT: :sigh: :wink: I suppose we'd better see what nonsense pysdm has been getting up to. Post the output of:


cat /etc/udev/rules.d/z80_user.rules
cat /etc/udev/user.rules


The two should be identical, but I'd like to be sure.

When we've solved this, remind me to give you a little homily on how:

1 - Out of the box, and with no tweaking, Ubuntu will automount USB drives and will mount internal partitions on an as-needed basis.

2 - If you need to mount internal partition on bootup there is no substitute for learning how to edit /etc/fstab manually.

3 - There are a number of 3rd-party mounting applications in the repos. They are mostly developed by only one person and are often unmaintained. Some (all?) are bad news. The bad news ones that I know about (based on the number of users of them that have needed rescuing from them) are pysdm, ntfs-config and usbmount. I'm sure we could add to this list.

Ok good news

I ran the codes you gave me to unmount and remount the drive and all is well.:)

I rebooted the machine and it booted normally without any errors. :guitar:

My windows boxes on the network can see the drive that I was having trouble with. :popcorn:

Yes now I know a good talking too about playing with setting you know nothing is due.
Then again how is one to learn. In the 3 years I have been using Ubuntu for my file server I have had more trouble with 10.04 than anything.

Thanks Alot

I'm glad to hear it! It must have been the remount option that was the problem. I've never seen it in /etc/fstab before. I believe it should only be used with the mount command from the terminal, so it's odd that mountmanager added it.

Wonderful! Pydsm creates a new udev rules file for you and doesn't put anything in it! Which is just as well, I suppose. :) Udev is used for automounting devices. Creating your own rules is quite OK but I was concerned that pysdm had muddied the water by creating rules which would interfere with what we were trying to achieve in /etc/fstab.

About 3rd party mounting apps, particularly those that edit /etc/fstab for you. I agree that there is a real need for a reliable GUI app to do this but as far as I can see there are plenty of apps, but not reliable ones - as you have seen! If you want to know more about editing /etc/fstab, this is a good place to start:

https://help.ubuntu.com/community/Fstab

Good luck. :)

How do I remove the /media/Stuff and the /media/More Stuff? I don't need any more confusion that I already have.

You don't want to delete /media/Stuff. That's the mountpoint for your Stuff partition, sda1 or sdb1 or whatever it's calling itself today. If you remove it you'll get an error on bootup because the system won't be able to mount the partition to the mountpoint defined in /etc/fstab.

The folder /media/More Stuff is doing no harm and is only taking up a handful of bytes on the drive but if you really want to remove it:


sudo rmdir /media/More\ Stuff

Yes, that's correct. You have to "escape" the space with a backslash.

By the way, mountpoints are simply empty folders/directories.
