removing mount points

[yoram]

I have this issue with mount points for some time. Its annoying and requires user input on every startup of the system.
On my 10.10 server I have some "leftover" mount points definitions that were originally mistaken, or, does not exist anymore.
On startup, I have to "S"(skip) them in order to complete the start up of the server.

I can see all these mounts in webmin (under filesystem) but can't access or remove them from webmin. Partly because they are mot mounted

Is there a way to fiddle with the mount list and remove all these not mounted points?

Thanks, Yoram

Hi Yoram.

Have you tried removing the entries from fstab:

Code: Select all

sudo vim /etc/fstab

Ian.

[yoram]

Thanks Ian, Works perfect

btw, any progress on the vnc for 12.04

[Ian]

Glad it worked for you.

Yeah, I'm making some progress on the vnc issue. Just trying out a few things. Only trouble is it is taking ~90 minutes to download the gnome components each time I rebuild a VM (normally only takes around 5 minutes). I'm guessing the whole world is hitting the Ubuntu servers right now so there is a lot of contention.

[yoram]

right.
I did it 3 times already. The GNOME-CORE is about 700MB .
Do you think that the problem relies in the server itself or in the GNOME (new version 3)? Could the older version of gnome solve this issue?

Regarding VM, my new server has the Intel E6750 that supports Intel's Virtualization. What is your recommendation for virtualization? Is it an app you install on the server or some kind of a basic infrastructure you install before the first OS?

Thanks, Yoram

I think the problem lies in the fact that the newer versions of Ubuntu use Unity rather than Gnome as the desktop. Clearly, installing the gnome components isn't enough to change things back to how they were on earlier versions. I should have it cracked tonight, assuming the Ubuntu servers are not still bogged down.

I'm happy with KVM so I'd recommend using that. Although it is an "app" you install on the server it actually uses the hardware virtualization built into the chip. ie. you can't use KVM unless your hardware supports it.
What plans do you have for virtualisation? Just being nosey.

Well, my main objective in virtualisation is to remove the extra stress of training from the media server. Currently running 10.10 on an old machine, I suffered
several newbie issues like the mount points issue that initiated this thread. I would like changes to be baked befor implementing them on the actual server.
In addition, trying other OS like the ubuntu desktop is always welcome and doing it without building a new machine is super.

I'm still not sure that I fully understand how sharing the system resources e.g. graphics, NIC, add in cards, disk storage etc. works .
For example, if I put two windows XP OSs on the VM, how could 2 different users have access to these two OSs? Via a client running VNC on ubuntu desktop?

I cant release all of my windows machines yet since there is a heavy and constant demand for "gaming horsepower" at home

Hi Ian
Since I wiggled with the mounts it seems that I damaged something.
When entering webmin, I have no the main screen only two bars (VS three) for real memory and disk space. The third (i think it was virtual mem) in missing.
And about since that time I can only write to the SAMBA shares. All reads are gone. I could see the directory structure but file reads are slow to non-existing

this is the fstab file after editing:

yoram@CAROLINE:~$ sudo vim /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' 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>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/mapper/CAROLINE-root / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=a9eeca00-0045-4627-a0a3-6fba4860aa65 /boot ext2 defaults 0 2
UUID=4b7f015a-fb66-40d4-a1b1-75307ef7573a /mnt/storage ext3 defaults 0 0
/mnt/storage /export/storage bind bind 0

SOLVED

It was a switch problem.
Bypassed the problematic switch and everything is fine now.

Hi Yoram,

Thanks for the update. I've been puzzling over your issue for a while now. Would have never guessed it was a problem with a network switch

Glad you got it sorted

Ian.
