Server :: XFS Filesystem Not Mounting

Sep 13, 2010

I have an XFS filesystem (not my root filesystem) that is not mounting.

We had a power failure over the weekend. All but one of our XFS mounts is comming up. Its a large mount (2TB) and I am not seeing errors per se...

But after attempting to mount it, it has been 4 hours and all we see in either dmesg output or in the messages file from the kernel is:

Our mount process is dead and I don't see any disk i/o going on. Am I missing something here on this?

I rebooted the box once earlier and was able mount read-only with norecovery...

I tried xfs_check and it also produced a dead "xfs_df -i -p xfs_check -c check /dev/sdd1"

Red Hat / Fedora :: Mounting DVD-RW As A RW Filesystem?

Mar 1, 2010

Is it possiable to mount a DVD-RW disk as a RW filesystem so I can do things like ...

mkdir /dev/dvd/mydir
cp ~/.profile /dev/dvd
ls -la /dev/dvd

I would like to use it, even create a partition on it using cfdisk or somthing. Can I do that ? If so, what is the mount command or tools I need ?

Fedora :: Mounting A Weird Filesystem?

Nov 23, 2009

Following a slight dose of vandalism, I have invested in a security camera system.It is basically a hard drive in a box which connects to a couple of cameras.There is also a USB lead to connect it to a PC, and some software that enables Windows to look at the recordings (I can't get it to work on WINE).I was hoping to simply bypass that, and just look at the drive directly, but it seems from here that the disk "doesn't contain a valid partition table".Obviously, the box thinks it has a valid partition table, else it would not work.I was quite surprised: I had assumed the box would have some kind of cut down Linux based system, but if that were the case, you would expect it to use a recognisable filesystem.

Ubuntu :: 9.10 - Admin Password On Mounting Filesystem

Apr 16, 2010

I am using Ubuntu 9.10 (along with Win xp). I have to authenticate everytime I mount filesystem (My d: , e: drives in windows). Or to connect to the internet (I use mobile broadband) I have to authenticate, also if I have to install something from synaptics I have to authenticate. I know this is good for security but I am the only person using my computer , so is there any way out of this authentication business.

Red Hat / Fedora :: Mounting Of NTFS Filesystem On RHEL6?

Jul 7, 2011

I am new to Linux platform and have installed RHEL 6 on my computer. I have gone through different posts on websites regarding how to mount windows drive on to the Linux file system.Here are few results of my trial where results are slightly overwhelming for a guy like me:

1. Mounting NTFS file system using mount commandAs a su-)
" $mount -t ntfs /dev/sda1 /media/MyFilesystem"

Output: error: unrecognised file system ntfs

2. I followed step by step instructions of installing Fuse and ntfs-3g_ntfsprogs but had no luck:

while using this command for the installation of for FUSE-0.9(which I guess prepares files for installation) I am getting this error :
" Command use: ./configure --exec-prefix=/; make;make install"

Error: "Checking Kernel source directory.../usr.src/kernels/2.6.32-71.e16.x86_64...Checking Kernel source version.......Not found "
Configure error: cannot determine the version of the Linux kernel source.Please configure the kernel before running this script.

Woooh , as u can see my Linux version is mentioned in that message so can anyone lemme know whether this issue is because of the incompatibility of Fuse with my version of Linux or am I suppose to make some changes in the command itself.

Ubuntu :: Mounting External Encrypted HDD With Ext3 Filesystem

Jan 20, 2010

I have a external HDD with eSATA and USB connectors available. I want to use this HDD to store my backups. The HDD should be encrypted (my main system is as well).

So here is what I did so far:
1) I used the following code to create the encrypted LUKS partition with EXT3 Filesystem:
Code:
cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 luks
mkfs.ext3 /dev/mapper/luks
The system always hang when I executed the "mkfs.ext3..." command, so I switched the HDD from eSATA to USB and then it worked fine.

2) When I switched on the ext. HDD the first time, the drive was recognized automatically and Nautilus asked for the password. I typed it in as checked the checkbox to remember the password in the future. For the backup I use a nice script that I found in another forum, where I can define a mountpoint and then the script will check for previous backups and only make a incremental backup based of the latest version. The script also mounts the drive automatically. In order to always have the same mountpoint, I want to make an entry in the /etc/fstab using the UUID of the ext. HDD.

Whatever I tried, it doesn't work. What am I doing wrong? Here is my current /etc/fstab
Code:
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/mapper/ubuntu-root during installation
UUID=2ea47421-73ce-4c66-9606-8a1db81ae640 / ext3 relatime,errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=dbdeb793-1d4e-43ea-8986-7b37fdbc9674 /boot ext3 relatime 0 2
# /home was on /dev/mapper/ubuntu-home during installation
UUID=42702091-83e6-43eb-aad1-108f43eedf9d /home ext3 relatime 0 2
# swap was on /dev/mapper/ubuntu-swap during installation
UUID=e225bcf9-908b-4226-a963-6b02ee658df1 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
# Eintrag wegen iPhone
none /proc/bus/usb usbfs devgid=125,devmode=666,nodev,nosuid,noexec 0 0
# external HDD
UUID=913977f7-8fa6-416f-af79-b5f913b68f53 /media/backup-hdd ext3 noauto,users 0 0
I made the "none /proc/bus/usb..." entry because it was recommended to ensure correct behaviour of the iPhone. Not sure if I need it though.

I created the mountpoint with this command:
Code:
sudo mkdir /media/backup-hdd
Now it seems the mountpoints owner is not root - strange right?
Code:
2 4 drwxr-xr-x 3 michael michael 4096 2010-01-15 02:45 backup-hdd
How should I mount this drive correctly? It will be automounted as every USB device, but that should not be the case. I want the script to mount and unmount the drive.

Ubuntu :: Error - Mounting /dev/loop0 On //filesystem.squashfs Failed

Ubuntu :: Mounting EXT4 Drives - Unknown Filesystem Error

Mar 6, 2010

I need to examine a hard drive that came from another system running Ubunut Server (not sure what version). I know the drive has LVM on it, so as far as I understand that means the drive will be treated as EXT4 for mounting. I can't boot from the actual disk, but I have used a IDE to USB connector to make a binary copy of the drive, which I've mounted as a loopback device. However, when I try to mount the loopback device properly, I get this:

root@~je:/# mount -o ro -t ext4 /dev/loop0 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

I tried using -t ext4dev too, but that just gives an unknown filesystem error. The file I've got mounting in /dev/loop0 is a .dd file, created by imaging the drive using dcfldd on the server drive while it was mounted (as /dev/sdb). System I'm working on is running Ubuntu 9.10. All I need is to be able to mount the server drive so I can traverse the file directories, there's a few things I need to check on it. If needed I can dispense with the whole loopback setup and just directly connect the server hard drive again using the IDE to USB cable, but I'd rather not do that; it's imperative that the drive doesn't get altered, or at least as little as possible.

CentOS 5 :: Extra Root Filesystem Folders For Mounting Device

Oct 26, 2009

I was looking at the root filesystem folder for mounting a device when I noticed extra folders. I'm using an encrypted filesystem so I'm not sure if it's that, a break in or the default Red Hat layout. I searched these forums and Google to no avail on extra folders. The root system contains the following:

bin {fda00e13-8c62-4f63-9d19-d168115b11ca} media opt selinux usr
boot home misc proc srv var
dev lib mnt root sys
etc lost+found net sbin tmp

Networking :: Mounting Unique Filesystem Or Directory By Network Booted Host?

Apr 6, 2010

I have a number of diskless hosts which are to bootth PXE and mount their root filesystem on an NFS share. Most of the NFS share will be common to to all of the diskless hosts. No problem with that part.I also need part of the NFS shared filesystem to be unique to each individual host. The only difference between the hosts is the ethernet MAC. I use it in the DHCP server to key a specific unique IP to each host. I would like to be able to use either the MAC, or the IP, or any other unique identifier that can be derived very early in the boot process to access a filesystem or directory that is unique to each diskless host.

I need/want to do this because I need/want to isolate all of the system maintenance to one small part of the boot host. Modifying the hardware (these are VME CPUs) in any way is not an option; they must be field swappable, with all maintenance isolated to the boot host(s).I know I could run ifconfig and parse its output to derive an IP &/or MAC, but that seems a bit kludgey and fragile. The DHCP server is presently assigning IPs. I know I can arrange to pass a unique option value via the DHCP server, but don't know if or how this can be retrieved on the diskless nodes. I am presently passing the 'root=' kernel argument from the bootloader, but I don't think there is any way to pass other filesystem information using that mechanism.

I know I can pass some kernel arguments from the bootloader, but there doesn't seem to be any generic message that can be retrieved in userspace as part of the boot process. I've scanned around in the /proc filesystem, looking for the IP or anything else that seems to uniquely identify the host, but don't see anything there, either.The init process has not yet been cast in stone, but is very likely to be a BusyBox built-in

I'm running CentOS 4.3 on a VM which is an application server for Quinstreet. trouble is when i keep coming in during the mornings it seems to keep making this root filesystem read only. There is no pattern for this and neither is it clear in the messages log why this keeps happening.
