I've installed aufs in order to seemlessly union two filesystems over /usr. One branch is the plain old, existing /usr directory; it's not mounted from a separate filesystem or anything. The other is a /usr on a microsd card. This is what I've added to /etc/fstab:
#the microsd mounted on /aufs/internal_microsd
/dev/mmcblk0p1 /aufs/internal_microsd/ ext2 defaults,noatime 0 0
#the aufs /usr union

View 6 Replies View RelatedI've noticed that the majority of the time I will double click an icon to launch and application the cursor activity (mouse loading/busy icon) will not show. The application will launch but there is no indication whatsoever that it's starting up. I haven't had this problem with other Linux distro's and I'm wondering if it's a setting or some sort.
I did notice that on a few applications it works just fine and it will do the loading animation. However, a lot of them will not show it at all. This is very frustrating especially if the application takes a bit to load and you don't know if you even launched it to begin with. Is this a bug or something that can be turned on?
I do hope I explained which animation I'm referring to. It's the circular loading animation that occupies the mouse when you are waiting for an application to finish launching. I'm not entirely sure if this is a gnome thing. Seem to work just fine on my old KDE desktop.
I have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.
Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.
These are the lines in my fstab
I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.
If I try to mount the AUFS filesystem from a nfs and local directory in Ubuntu 9.10 like this:Code: sudo mount -t aufs br=/mnt/nfs=rw:/home/data/local=ro none /mnt/union.I get segmentation fault and my system crashes: Code: comm: file 2 is not in sorted order mount: block device none is write-protected, mounting read-only
Segmentation fault.Am I doing something wrong or is it a bug?
I've got a server with bit of chaos on it. There is similar data on different partitions which I like to mount remotely with samba. So I setup aufs on the server and then share the merged aufs directory (as read only). All seemed fine, and I was able to mount it nicely. However, when I enter the directory in question does the kernel on the mounting puter start misbehaving.
First it freezes for about a minute. Then I get a bunch of oops-looking messages in dmesg and the system eventually locks up totally. This is what it looks like:

As recommended, I'm creating a new thread for my configuring GRUB problems commented first hereWe are setting up a new version of a custom system, we are migrating to Ubuntu Karmic from another distribution (Slackware). Besides small differences between these systems (most of them from the most recent versions of software used by the latest Ubuntu, such as GRUB 2), it has been decided that the new system will run an union root partition using aufs and tempfs, basically, we are following the steps provided heree install the system to a new hard drive from an already running Ubuntu Karmic system, usingdebootstrap/chroot, we move the disk to another sytem, so we have to correct disk references, we are able to run this system and it behaves correctly the first time it boots, it bypasses the GRUB menu since there are no other systems detected. However, after halting the system and booting it, the GRUB menu appears with a new "recovery" option, we've managed to remove this recovery option usingGRUB_DISABLE_LINUX_RECOVERY=trueBut then, the GRUB menu appears again, this time with only one option to boot: our system installation. But when this GRUB menu appears, it has no default timeout and so it stays forever unless ENTER is pressed to boot into the selected entry.
The main problem is that we are unable to configure GRUB inside the new installation because it always returns this message:grub-probe error cannot find a device for /If we boot the system "normally" (mounting root to a normal partition), we are able to configure GRUB properly, but it does not behave the same when using the union file system as /We are only looking for a way to bypass the GRUB menu and boot our system, do you have any advice on how to properly configure the GRUB menu for our system
I have a netbook I am setting up for our class (30 in all when I get it working). I had pam_mount working at creating the mount and unmounting with version 11, but I ran into some problem and am trying to reproduce the same results with Fedora 12. The only problem I seem to be having is the umount process. I don�t even see pam_mount trying to unmount at logoff in the log. Here are the conf files that should be relevant.The part I am getting stuck on is there is no output in the message log and I have the exact same setup on a Fedora 11 setup and it works no problem.

I am using ubuntu8.04 and i am not able to umount my usb using unmount option even as root on command line.
If i try the same using mouse right click, it showing error mesage as follows. "Cannot unmount volume. The volume 'STEEVEN_1' was probably mounted manually on the command line. Details: Device to unmount is not in /media/.halmtab so it is not mounted by HAL."
usb label is appearing even after the unmouting the usb manually.
next time mounting adding another hyphen to the usb label as follows.
steeven_1, steeven_1_, steeven_1__, steeven_1___ etc.

View 9 Replies View RelatedI am writing this software that creates virtual block device nodes almost like loop does. I need to allow non-superusers to mount and umount filesystems from these devices. I don't know the names of the block device nodes beforehand so i can't use fstab entries to add "user" or "owner" flags there.
Currently i solve this by providing a small suid helper tool that verifies that this is indeed "my" block device the user is trying to mount and then just call /sbin/mount or /sbin/umount to do the job. This is definitely better than setting a suid bit for the whole program but not really perfect.
I managed to boot from hard disk, everything works ok. But Gparted has a bug, it works in Live Hard Disk, but not when I click the install icon because it can't umount /cdrom. But I solved that by formatting ext4 and swap area from gnome-panel Live Hard Disk and only put mount point / after click on install.But problem stroked back: install is not possible because it wants to umount itself before installing, wich cannot be possible. I'm installing it in a new place /dev/sda5. Live Hard Disk is booting from /dev/sda3.

I've mounted a share using standard nomenclature for the NFS mount command with the following command line:
mount -t nfs -o rw {IP address1}:/ /mnt_for_70 / {IP address2}(rw)
mnt_for_70 is a mount point I created on {IP address2}
I'm confuse and want to be sure I use the correct command on the correct host to correctly umount the nfs share.
Would I execute umount /mnt_for_70 on {IP address2}
Not sure if such a simple command will work. As this is a semi-production host pair, I hesitate to just umount so simply & I have no test systems to try this on...
I need to do mount/umount operations in my c program. But my program can only be run under normal user. However, the user who run my program have sudo priviledges to do mount/umount operations. How can i apply the sudo privileges in the mount(2) system call?

I have a network share mounted with cifs which does not work as expected. It should automount at boot and dismount at shutdown. It does not automount at boot, but "# mount -a" will mount it in the gui after booting finishes. This I can live with, but at shutdown or reboot, the cifs share hangs for about 30 seconds before dying. My /etc/fstab entry code...
I saw a bug report about the cifs umount issue, but can't find it at the moment. I did notice that it was a very old bug. If I remember to do "# umount /media/data-srv" before rebooting, all is fine, but I seem to constantly forget and then stew as the system hangs for an extra 30-45 seconds. I've tried several things to automate it including shutdown scripts added to /etc/init.d/ and elsewhere, but nothing seems to work. Anyone have this issue and find a work-around?

Recently I was trying out a boot disk I had made, and basically, I switched it off several times due to it booting the completely wrong kernel. Now, I'm getting to the stage "Checking File systems" and then comes up [Failed]. I then get a message saying Reboot required, and that it will reboot in 15 seconds, just a few seconds before it reboots I get "/dev/shm not mounted, /dev busy" or something similar.
I've booted up my sysresccd, ran "fsck.ext4 -fcv /dev/sda2" to force a check and scan for any bad blocks, it came up clean, then I rebooted and got the same error, so I copied the kernel and system.map over to /boot to make sure there's no corruption and reinstalled initscripts and util-linux-ng, rebooted, same error.Tried different kernels, I've checked fstab and menu.lst, no problems there, so I still don't get why I still get the same problem.
Am wondering if looking at the CPU process queues, vs CPU% busy, are a better indication of whether an upgrade is needed.
Afterall, processes can still queue up to be processed even if "top" doesn't shown CPU 100%. Say if it's indicating 50% busy within the top output, it's only saying that 5 out of 10 times sampled, the CPU was busy. But a process may arrive to be processed at any time, and if it arrives just when the CPU is processing something it needs to wait in the queue. Am I making senses?
How many processes queued up would suggest an upgrade is required of the CPU? I've read online (believe it's Microsoft) that 2 is the figure.

I have inserted my handy drive. However, when I right click and select unmount I get the following message:
Code:
An application is preventing the volume "New Volume" from being unmounted
So I try from the command line:
Code:
umount /dev/sdb1
And I get the following message:
Code:
umount: /media/New Volume: device is busy. All I have done is copied some files to my handy drive. So I am not sure what process is keeping my handy drive busy.
Is there any command that I can use to see what process of anything else is using the handy drive?
I am not sure when this started for me, but I think in a recent update of Firefox. I am running Ubuuntu 9.10 Karmic Koala. I am currently running FF 3.5.6. When I click on a link in a page, or refresh the page, the Arrow/Pointer cursor stays the same in place of the normal busy cursor that I am used to. This is more of an annoyance than a real functional issue, as I can't tell if the page is working except to see the tab showing loading, and the status bar in FF. I have searched the forums, and google/linux, but have not found a cause, nor a fix.
I also use Opera and Chrome at times and the busy cursor works there as expected. I also use Thunderbird and it is working there. So, I believe it is only related to FF. My addons are as follows, but I haven't added anything recently, and it was working before.
