Ubuntu :: Partition Is Slow To Mount
Jan 10, 2010
I'm experiencing something pretty weird with single partition of a physical disk that contains other partitions. I have observed twice already that after a boot that particular partition is not available, i.e. it does not appear to be mounted. When I tried to manually mount that partition, I got the message "not mounted or device busy". Unmounting the device showed that it was actually not mounted, although I cannot fathom what would keep the device busy. It is the only partition on that physical disk that has this problem, which is good because my root partition is also on this disk.
The first time I had this I tried rebooting a couple of times (after, unsuccessfully, trying the manual mount) and it seemed to work. The partition became available again.This time I was still busy googling for it when suddenly the partition became available, i.e. it had mounted. After a reboot it stayed that way.As I am unable to comprehend this and quite convinced that it will pop up again in the future, I wonder if someone else has seen this or knows what is going on.All partitions are formated as ext3 and I'm currently running karmic (clean install), although the offending partition has not been touched since 8.04. My machine is a Dell Studio 17 laptop.

KDE 4.6 - opensuse 11.4.
I have a separate ext4 partition which contains all my data (music, movies, etc). When I delete files from this partition it is very slow because it copies files from my data partition to the Trash folder in my home partition. How can I avoid this? Can't the trash be configured so that it uses a trash folder in each partition instead of copying files to another partition (which is slow).

what now trying to mount partition get this error this is the partition ubuntu 9.10 is installed on and upon reboot error no device with a long string. mount: can't find /dev/sda6/mnt in /etc/fstab or /etc/mtab
so now that I believe I've successfully mounted the partition how do I direct the bootloader to this partition /dev/sda6 on /media/11076e45-e27d-470b-bb6d-6894f7809a0c type ext4 (rw,nosuid,nodev,uhelper=devkit)

I've just bought a HP mini compaq laptop. The laptop doesn't have any CD/DVD "reader". So i was forced to download the .iso file to install ubuntu in addition to Windows XP that was present when i bought it. To do so i used UNetbootin, and i used my only hard disk as a live CD. But when i wanted to install ubuntu, they told me to create a partition. The problem is that i can't. I have only one partition sda1(nfst) which covers the whole stockage memory, and an empty space(8Mo). I can't acceed to any of the resizing or modifying options to edit the nfst partition. The only options are manage flags and umount. When i click on this one, they tell me : # umount /cdrom : cdrom is busy.

I've followed the instructions on the guide to make a triple boot for macbook 5.2 generation.
ATm I'm only with DUAL boot: OS X and XP coze of the karmic koala version of ubuntu doesn't got the package gptsync I need and I'm not expert enough to do what is said in this thread [url]
BTW my problem concern windows:
I've installed it and I've installed also the drivers from apple CD btw When I boot windows for the first 1/2 minute once I do anything its freeze like if it would be out of ram and after 1 or 2 minute it start to work without problems and doesn't freeze anymore
but I'm feared about this freeze that I get the first time I make something.

Using Fedora 15 64 bit. The problem is when I put in a USB stick (directly into USB port front or back), or SD memory card via Card reader, they take a long time to auto mount. About 30 seconds. I've tried a few different USB sticks and memory cards. Once mounted they work fine. This is a new install, been running for a few weeks, but the problem only seems to have started in the last few days. Also, not sure if it's related, but now Shotwell takes about 30 seconds to start. The screen comes up, but the interface in non responsive for around 30 seconds. Both USB and Shotwell problems seem to have started at the same time.

I used command as followings. nothing special. mount -t cifs //192.168.55.53/windows$/Home /mnt/ -o user=username%password It works well after mounted. But mounting itself takes 1-2 minutes terribly. After mounted successfully, file transfer speed looks to be normal.

I would like to know if it is normal to experience 10MB/s data transfer rates during copying between partitions on my local hard drives (Toshiba 250GB 5400rpm SATA) while having three times faster (30MB/s) transfer rates between local partitions and USB drives (Kingston 8GB).

I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.
[Code]....
Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.

I'm using Fedora 12 since 2 years lately, I really enjoy this S.O., it's quite robust and wonderful, but a couple of months ago it is really slow to boot up when startup the computer, I've checked everything, but seems to be ok, I had a partition lost arround that date, but recover successfully, it happens when I run gparted that It cannot see partition on my 500 GB disk, but still boots up. When running Mandriva live cd, it can see (?) all partitions on that disk, even with Fedora Dolphin I can access this partitions. What could it be?

I need to know the necessity of swap partition in Ubuntu.. I have recently bought a new HD and installed Ubuntu(with NO swap,only Ubuntu on a single partition) on it and am facing frequent,random hanging issues with it.. Earlier,my old HD used an swap partition along with main partition and i never faced hanging issues at that time..
Actually, when in hanging mode,the cpu light keeps blinking continuously and the mouse movement is very slow,the screen also becomes dim.After sometime,it comes out of hanging mode and mouse movement becomes normal.Sometimes,even after waiting for 15-20 minutes,it does not come out of hanging mode and the system has to be restarted.(this is what forced me to look for a possible solution to this)

is there a way to mount another partition on any OS really, and then in a window in the current os, boot and run that partition?
for example, im in Ubuntu and i mount my seperate arch-linux partition. then via some magical software, boot it and run it in a window, so now i am in ubuntu checking my email, and simultaneously in archlinux on facebook in a commandline using links or something.

What file system should I use to partition a slow and old hard drive? I know that ext2 was best for old computers which mine is not but I am using an old hard drive for extra storage and I was curious if anyone knew if using ext2 or ext4 would show any performance differences.

When I try to boot I get this error message:
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the systemwait long enough?)
- Check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/c946b41f-2f8f-4a28-8478-11a50d6fc0e8 does not exist. Dropping to a shell!
Booting from my 9.10beta livecd sudo fdisk -lu shows my root partition (sda5) but blkid doesn't, and there's no way to mount it.
I know similar questions have been posted before but they all involve using fsck or e2fsck, which don't work with my ext4 filesystem.
FYI Acer Aspire 7535G Kubuntu 9.10 AMD64

I was reading this about setting up boot partition to not mount automatically. [URL]
Quote:
Some users don't want their /boot partition to be mounted automatically to improve their system's security. Those people should substitute defaults with noauto. This does mean that you need to manually mount this partition every time you want to use it. Add the rules that match your partitioning scheme and append rules for your CD-ROM drive(s), and of course, if you have other partitions or drives, for those too. Now use the example below to create your /etc/fstab: how to set up a boot partition.

1- Do I have to mount each partition after each boot? Is there an automated mounting the partitions?
2- Can I have a "My computer" icon on the Desktop?
3- There's a problem that occurred just now.. Yesterday I connected to another monitor, Today, after logging in - using the laptop display -, the icons on the task bar are shifted to the left.. Here's a snap shot.

On startup my computer tries to mount a partition which I deleted (called Misc) and combined with the space of another. I get this message:Quote:The disk drive for /media/Misc is not ready yet or not supported. Continue to wait, or press S to skip mounting or M for manual recovery.I also notice that the folder for the drive is still listed in nautilus. How do I get rid of it once and for all?

If I try to boot this is the result:

And If I try e2fsck /dev/sda1, it refuse to run stating "Device or resource busy while trying to open /dev/sda. Filesystem mounted or opened exclusively by another program?" How can I recovery my data at least?

I turned on my laptop today and noticed a load of unfamiliar startup text so I knew something was wrong. Now whenever I startup my laptop, GRUB loads fine but when I try to start Ubuntu it says the following:
Quote:
mount : mounting /dev on /root/dev failed : No such file or directory
mount : mounting /sys on /root/sys failed : No such file or directory
mount : mounting /proc on /root/proc failed : No such file or directory
[code]....
so all I'm left with is this BusyBox command prompt. I'm on a live Ubuntu CD right now and if I try to mount /dev/sda1 either in the terminal (with the mount command) or with the GUI it just gets stuck.
Quote:
This will provide you with a list of your drives and partitions, you need to pick the one that your root file system is installed to, it will be something like /dev/sda1 but in my case I can't even mount /dev/sda1. When I run sudo fdisk -l heres what I get
Quote:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
[code]...
thats weird because I rebooted with a live Ubuntu CD and didn't even try to mount /dev/sda1 this time. The instructions were to then try to mount the drive from the GUI so heres what happens when I do that: it attempted to mount it for about a minute then gave me this error message When I tried again heres the error it gave me The problem seems to be that /dev/sda1 can't be mounted for some reason.
I don't know what that error message means and I don't know what else I can do to further diagnose /dev/sda1 and find out why it can't be mounted. Ordinarily I'd just reinstall Ubuntu but I have a couple of lab reports that I had saved on that partition so I'm in trouble if I can't figure out how to access the partition.
EDIT: At the end of that other thread someone recommends to use testdisk to recover the data from the partition. All I really need to do is get those lab reports back but I had them saved inside a Windows 7 guest on Virtual Box. Will this complicate matters a lot for me?
UPDATE: I tried to reinstall Ubuntu and it wouldn't work. Seems this is a bigger problem than I suspected. Does this mean my harddrive is corrupted? I can still use the Windows 7 partition but I take it that the Ubuntu installer not working is a bad sign.

im looking for a command for mounting an ntfs partition. what i want to do is to put that command to the "after startup applications" option. that's because that ntfs partition is my storage partition, i play steam games [win7 dualboot, thats why that partition is ntfs], download movies etc. in my places menu, its called 190GB Filesystem, and when i click it, it mounts up. but that means i have to click it everytime i boot up, because vuze can't locate the files if it isnt mounted.
by the way : /media/7C1EE4E21EE49684 when its mounted

I keep a separate partition for files and folders which I absolutely need for my college work. (I do this because I had accidentally wiped my /home partition while upgrading Linux before)
Anyway, I want to know how to mount this partition at boot automatically .. I know I am supposed to append an entry to /etc/fstab but I am a lil apprehensive about doing this without a go-ahead from users here.code...

I was dual-booting Ubuntu (10.10) and Windows 7. I installed Backtrack in addition to these 2, and the Ubuntu GRUB was replaced with the one from Backtrack.
Now when I boot, only Backtrack and Windows 7 are listed in GRUB. When I run fdisk from Backtrack, I see all partitions, and running a Partition Manager lists the Ubuntu partition as a Linux partition. However, the partition manager says that it is unable to read the contents of the partition, and that it is unable to re-read the partition table.
Also, the Ubuntu, Backtrack, and Linux Swap partition are all listed under the same Extended partition.

I am having a dual boot system vista/ubuntu 9.04. Till recently whenever I wanted to access my vista partition I had to type in the administrative password. However, strangely, for last few days whenever I access the vista partition I don't need to type the password. The partition is just mounted and I can access the files. I would like to know the reasons and if possible to get back the previous situation (needing password to access the vista partition).
