The /mnt/ext is mounted to an ext2 filesystem, an external hard drive. For some reason I can't run scripts from there. Please see the session below.

I administer a remote server via SSH that runs CentOS 5.5. I have been unsuccessful in all my attempts to write to two different external USB hard drives with a single ext3 partition when logged in as root.
When attempting to create a "test" directory I get one of two messages:

Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:

Keep in mind this is a newly-formatted, empty drive.
Not putting stock in the odds that I've had two hard drives (different sizes and brands) with the exact same hardware problem, I'm going to assume this is a software issue, although maybe it isn't. Hence, my post in "Linux - General". I've heard talk elsewhere of controller (chipset) issues coming into play. Is this valid?
Okay, here's the information you'll need to make a diagnosis....
Here's the output of a "df -h" command:

There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
I've got someone with access to the box if necessary. But it might take days to implement solutions since this isn't his full-time job. Remote solutions are, therefore, preferable.
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.
View 5 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.
Hard drive is connected to my Inspiron 1525 via USB, plugged in and I'm not seeing the new drive mounted. Restart doesn't fix things and manually trying to mount /dev/sdb1 doesn't work either. The drive I got is preformatted as NTFS and I've been using a logical partition formatted as NTFS as a sort of share drive between my Windows partition and Ubuntu partition, so I know I have NTFS set up properly. This is the hard drive I'm working with for reference.
View 3 Replies View RelatedWhen I plug in my external USB Hard drive which is formatted as a single NTFS partition, it is recognized and mounted automatically, a nautilus window pops open. Unfortunately it is not writable. The reason is: the partition is mounted "ntfs" (which lacks write support) instead of "ntfs-3g". This is the output of mount after plugging in the drive:
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type ntfs (rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,dmask=0077)
I want this partition to be writable by just plugging it in.
The partition should not have any errors because a) I fsck'ed it windows and b) mounting it manually works:
$ sudo mount -t ntfs-3g /dev/sdc1 /media/disk_/
$ mount | grep sdc1
/dev/sdc1 on /media/disk_ type fuseblk (rw,allow_other,blksize=4096)
$ devkit-disks --mount-fstype ntfs-3g --mount /dev/sdc1
Mounted /org/freedesktop/DeviceKit/Disks/devices/sdc1 at /media/4EBC5FB82435B0EE
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
$ gnome-mount -nbtd /dev/sdc1
$ mount | grep sdc1
/dev/sdc1 on /media/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
How can I get ntfs drives to be mounted as writable by default, preferrably without having to modify fstab?
I'm trying to understand the last few hours... I installed slackware 13 yesterday in a multiboot system. On a seperate hdd from all the OS's I have my mp3 collection......I could play the mp3's as root after manually mounting sdb, but as a user I was unable to play them even though I chown'ed and chmod'ed 777 until I mounted sdb in fstab. The second drive was formatted ntfs by vista.

How 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?
Noticed this in both Ubuntu 10.04 & now Mint 9, both Gnome. I didn't have PCLinuxOS2010 KDE installed long enough to experience it so I don't know if it's a property of Linux or part of Gnome.I have two users, both myself and my wife, and I noticed thatn I mount an internal SATA drive I can only see/access it under the user that mounted it. In order for the other user to see it I need to un-mount the drive. Drive is a 1TB SATA formatted NTFS.I can't imagine this is normal and the 2nd drive is shared for pics/data/etc. Strange quirk is that my install is on a partitioned primary drive, 320gb, that also has Windows on it so the OS must access the drive in order to boot - both users can see the mounted 215gb Windows NTFS partition simultaneously.Is there a setting that needs to be changed or is this normal?
View 8 Replies View RelatedMy version of linux has a bunch of GUI icons on the left hand side of the screen (vertical). Most are links to programs.You click the GUI icon and the program opens. When I mount my internal hard drive it adds a GUI icon for the drive. The problem is when I click on this new GUI icon it automatically loads K3b and gives an error message instead of giving me a list of what is on my drive. I deleted the program K3b and tried un-mounting then re-mounting the drive. I then tried the new GUI icon for the drive and now it automatically opens Dragon Player.
View 1 Replies View RelatedI am running Linux Mint on my primary hard drive, and I would like to access some folders I have on my second hard drive, which has Windows XP installed on it. However, whenever I try to use these folders, I am greeted with the error message, "The file is not marked as executable." While I know how to set files as executable whenever I am using folders on my Linux drive, whenever I try to set such permissions on my XP folders, I can't seem to make it work. The files revert to their former status, and I'm told that I don't have permission. Should I set the files as sharable from within XP, so that they aren't marked as read-only? Or is there another solution I've missed?

/mnt/sdb1
I've got an external HDD from Iomega that I've been using for over a year and lately it's been doing this thing where it suddenly changes from /dev/sdg to /dev/sdh while the partition on it is still mounted, seemingly at random. I'm often (not always) able to look at the contents of the partition, but it gives me I/O errors followed by a list of files and directories.
I am using slackware64 13.0 running kernel 2.6.29.6. Below I've provided the relevant lines from dmesg (edited out irrelevant lines to keep post under max character limit.) I'm beginning to suspect NFS has something to do with this, but I can't even begin to imagine how.
When this happens I'm able to umount -l the partition and remount it using the new /dev/sdh1 but eventually the same thing just happens and the whole drive switches back to /dev/sdg. This problem persists between reboots. It's also happened with an ext3 filesystem, in fact I switched to ext2 because it kept telling me "Aborting journal" and I was afraid I would get a corrupted journal and perhaps a destroyed file system.
About 8 months ago I was doing some work at my brother's place and while down on the floor fiddling with cables I yanked this whole drive off the desk and it smashed into the floor (while spinning probably, I'm pretty sure this model is disk based.) I've been expecting to see some strange behavior since that happened, but it took a while and I can be certain this is related to that incident, although I'm rather convinced it is.

My external hard drive randomly unmounts in the middle of file transfers.
The system is Debian Wheezy with sda as single-partition ext4. I have an INEO I-NA212-J USB 2.0 enclosure with 2xHDD single-partition ext2 which are recognized as sdb & sdc.
When files are transferred from the external to sda, the system will unmount the external drive at random times. When that happens, "fdisk -l" no longer reports sdb & sdc, but does show the drives as sdd & sde and they can be mounted. I have to reboot the machine to have it see the drives as sdb & sdc again.
When transferring from sda to the external, the unmounting is less frequent but I get file corruption. For example, a large directory seemed to transfer successfully, but the result showed as a single executable file and the displayed file properties were just long strings of numbers. Deleting the file did not reclaim the space.
There seems to be no pattern to the failure. I have checked for file size, number of files, system uptime, transfer time, etc. I have so far not seen it happen while there is no activity. The problem is the same whether there are 1 or 2 drives in the enclosure. However, I have used USB thumb drives and microdrives (both vfat) without problems.
For mounting, I have tried both "mount" and "pmount", and for file management both Xfe and Midnight Commander.
I have 2 ubuntu's: 1 on my ineternal hard drive, 1 on my external
When I startup without my ext drive =>GRUB error 21.
And when I plug it in I can choose: the standard ubuntu kernel is the one on my external, and the original one is listed under other...
I'd like to be able to startup without external hard drive and make the ubuntu on my internal drve the standard.
I have just installed Xubuntu and suprisingly it did not ask me to create a partition within its installer like Ubuntu does. So now, I am left with 150mb of free space. I want to expand that amount. The problem is, I do not know where it has been installed on. I have a C and an E drive. Currently, the C drive is mounted and the E drive will not mount even if i press the mount button. Does anyone have a solution?

I have a headless 8.04 server with 2 USB drives attached. I'm trying to move everything off the 1.5TB drive onto a few 300GB drives (so I can then use LVM on the 1.5TB drive and move everything back onto LVs.)I check the drives using 'fdisk -l'. They show up as sdc1 and sdd1. I mount them and start a cp operation.When I run fdisk again, the drives are no longer sdc1 and sdd1. Now they are sde1 and sdf1 (and of course, they are no longer mounted.
What could be causing this and how do I fix it?I need to fix this ASAP because the 1.5 TB drive seems to be going bad. Every few seconds I hear a big "click" as though the head arms are smacking against a stop. (This is the 2nd brand new 1.5TB drive that has started doing this!)
