Writing a bash script and I need to check if a known HD partition is mounted or not. I do not think /etc/mtab is the place to check. Would /proc/mounts always work? To make it simple like this : cat /proc/mounts | grep /dev/sdb2

View 8 Replies View RelatedI am running slackware-current and using the Novatel usb760 3G modem. before i use kppp to "dial out" I have to eject the device. It works fine except that i periodically get a popup window with:

it happens every 30 minutes to every 10 seconds. anyone ever experience something like this?
A non techie friend has helped an even less techie friend by contacting me by email to discuss an ailing laptop. A few emails were exchanged, with more details, and it was not looking good because it seemed that suddenly the CD drive was not responding, nor any USB devices, the wireless icon was gone, but Ubuntu still seemed to work (for now), with wired ethernet also working. I was struggling to think of what could be done, with the favourite routes of Live CD and Live USB apparently gone.
After a few more hours - another email: 'It's now working! After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'I see there is 'Disk Utility', and this would presumably fit the bill, but how does it do checks and repair when the damaged file system is being run, and is currently *mounted*? I thought utilities like fsck(?) could only be run on unmounted file systems? Have I misunderstood the disk utility fs check repair function? And anyway, what might be a good answer to my (nontechie) friend's question 'After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'

I'm writing a script to rsync some directories to external hdd for backup.
My external hdd gets automatically mounted to /media/backup1
My script then backs up predefined directories to /media/backup1.
I have added this script to cron to run once every day.
The problem is that in the case where the drive is not plugged in and the script runs, it backs up to my local hard drive, and since it is more than 70% full, it fills it up by duplicating that 70% onto itself.
I have taken the script further, to test whether /media/backup1 is mounted. If it is, the backup will run. If it is not, it will bail out.
I'm using the mountpoint program to test for mounts.
My script so far:
Code:
#!/bin/bash
if [[ `mountpoint /media/backup1` ]]; then
echo "filesystem mounted"
# The backup function. Commented out for testing.

Is there a way to disable disk checks in a mounted usb drive? I have a 500GB usb mounted drive in my CentOS machine and everytime I reboot my system, it does disk checks which is a long painstaking process.

I have two external hard drives mounted to my computer. They both work and are accessible. The one shows up on my desktop when it is mounted just fine. The other one does not. I went in to Configuration editor-apps-nautilus-desktop and checked the volumes_visible. That makes the other one not visible/visible but not the one I am having problems with. I read somewhere that devices must be named for it to show up and both devices are named, I even changed the name and that didn't do anything. Again, this device shows up in my computer but not on my desktop like all my other devices do. If anyone has any ideas on how I can get this external hard drive to show up.
View 1 Replies View RelatedI'm not sure if this is a bug in Squeeze beta 2 or if it's something I've overlooked. I have a Maxtor 250 GB external USB drive that I use for backups. It gets auto-mounted fine, always in the same place, and from my normal user account I can write to it, even delete directories on it if I want to. But when, from Gnome, I select the "Safely remove" option, I get an error to the effect that it can't stop the device. The weird thing is that the thing actually *is* unmounted. I've checked the mount point and it's no longer there.Is there some package I maybe should've installed but haven't? I'm not really worried about data loss, since I'm sure the drive wouldn't unmount unless it was properly synched; it's just the error message that bugs me.
View 2 Replies View RelatedHow do you find the device (e.g. /dev/*) for a mounted USB drive in Linux (Ubuntu 10.04)? I'm trying to format a Cruzer USB flash drive, and when I plug it in, the icon for the mounted filesystem appears on my desktop. However, when I open GParted, it doesn't list the filesystem as an option to partition.
The recommendations I've found through Google include monitoring tail -f /var/log/messages, which they claim should list the device name when the drive is mounted, but this never happens for me. I've also read that the USB drive would usually be linked to /dev/sdb, but this appears as a broken link on my filesystem. How else would I find the device?
I've some icons of mounted devices on my desktop. I want to display only some of them which I need. All drives are mounted automatically while booting or by scripts while logging in.For example: I've 4 mounted devices and 4 icons on my desktop and I want to have 4 mounted devices but only 2 icons.There is possibility of hiding all of icons in gconf, but I want to hide only some of them.Is it possible?
View 4 Replies View Related[openSUSE 11.1, kernel 2.6.27.45-0.1-Default, Gnome 2.26.3] I have a problem where I have an external USB drive which mounts at boot, with /home aboard it along with several data-only partitions, and if I try to add another USB drive *after* boot, the system changes the device IDs previously given to the original drive. The already running sdb now becomes sdc. If a user or processes are attached to /home when this occurs they are left in the twilight zone and stuff starts crashing. An added weirdness is the newly added drive isn't stealing the sdb ID, the added drive becomes sdd instead, and nothing at all is left at the sdb ID.
Note:
- System boots from sda, a non-USB drive with the system as well as /swap onboard, that should be uninvolved with the problem.
- Among the 4 partitions of the boot-mounted USB drive there are 2 lux-encrypted partitions (ext3). One is /home (originally encrypted under 10.3 and added back after machine upgraded to 11.1) and another being a data directory (later encrypted under 11.1).
- The problem _may_ occur only when the additional added drive is also lux-encrypted, but this may or may not be always true as I have limited other USB stuff to test with, most of it is also lux-encrypted.
I've recently started using Linux Mint (version 10) on a Dell Mini 1012 netbook. I'm using a loop device to mount a file on a NAS but whenever this loop device is mounted and has been accessed, my machine fails to shutdown.
Firstly I mount a share on the NAS using cifs (the NAS is aimed at Windows machines so doesn't support NFS). I have a sparse file on the share (which I created using Cygwin in Windows, using the dd command).
I used losetup to create a loop device and formatted it as reiserfs.This works and I can successfully use the mount point. I'm using it with Backintime.If I try to shutdown my machine without unmounting the loop device, shutdown hangs.
These messages just keep repeating and the system never shuts down.So I assume the problem is something to do with unmounting the CIFS/loop device.If I unmount the loop device all is fine. I don't need to unmount the cifs share.Any ideas on how to resolve? Should I add a script to run during shutdown (i.e linked from /etc/rc0.d and /etc/rc6.d) to sync and unmount the loop device? Or is there a better solution?
Can we export a raw device through NFS/CIFS to be mounted at remote location?

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..
Im trying to get away from the world of M$ into linux and I think slackware is the way to go for me. In particular SW13-64bit. My question is though I dont see many hardware manufacturers supporting SW, but I do see suse and redhat. How hard/possible is it to use redhat suse drivers for slackware? Can they be modified/rebuilt?
Im also considering buying a cheap server off ebay to use. Can someone let me know if any of the following would cause an issue with slackware?In particular the Adaptec sata raid controller which I want to run in raid 5.
I've just installed Slack 13.1, this was a "clean" install. All seems to be working well except for the dvd-rw, but this is a show stopper, if it doesn't get resolved in a few days I'll have to go back to 13.0.
The drive is detected correctly, but if a cd is mounted it gets errors, and is unable to set it up (it doesn't appear on the desktop).
Here is the info from dmesg:

I'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:
Code:
The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?
I have been working on this way too long now...this *should* be simple. I must be missing something simple at this point.
