actually we are using samba and that it was mounted in usb device which is read/write mode for sharing a file to all the system,it was properly working in half an hour,then after that it was automatically changed in read mode .if this problem occurs we are going to reboot the system then the problem will be resolved.
View 1 RepliesSetup1: Two rack mounted servers with a common storage device serving as the home directories for users on the servers. The storage device is a gfs partition mounted on the servers as the home directory using SAS cables. These servers have RHEL 5.4 as the installed operating system.
Setup2: A standard tower server with Debian 6 as the operating system used for tape backups. This has a tape drive connected to it.
Question: How to mount the storage device of setup1 using NFS on the server in setup2.
I have installed live cd on usb pendrive. Everything works great. How can I find out which device driver it is using? Where are the device driver files stored? How do you specify the device driver when mounting a device?
View 3 Replies View Relatedi am using ubuntu studio karmic and i have a digitech vx400 audio effects pedal which serves as an audio in/out midi in/out device via usb. i can sucessfully set it as the system sound device in system>preferences>sound for both input and output. but, when i play audio through it it only works for a few minutes before the sound stops completely. if i leave the system settings set to the internal sound card and configure jack audio connection kit to go to the usb device, i get the same results on the usb sound. a few minutes of playback at the most.i can restart sound with either "pulseaudio --kill && pulseaudio --start" or "alsactl init" in either situation. just requires restarting the programs. same results after restarting. i think this is alsa related as i have both the system sound and jack using the alsa driver, but i don't truly understand the relationship between pulseaudio and alsa.

Having some troubles mounting my DVD-RW after a reinstall of ubuntu. Now using 10.10.
Code:
root@Johnsky:/# wodim --devices
wodim: Overview of accessible drives (1 found) :
-------------------------------------------------------------------------
0 dev='/dev/scd0'rwrw-- : 'HL-DT-ST' 'DVDRAM GH20NS10'
-------------------------------------------------------------------------
So there's my scd0 sitting pretty.
Trying to mount it.
Code:
root@Johnsky:/# mount -a /dev/scd0 /media/cdrom0
mount: /dev/sr0: unknown device
root@Johnsky:/#
sr0?
Code:
root@Johnsky:/# ls -l /dev/
total 0 .....
Lets try mounting sr0 directly instead.
Code:
root@Johnsky:/# mount -a /dev/sr0 /media/cdrom0
mount: /dev/sr0: unknown device
sr0 is still an unknown device.
I'm thinking when I reinstalled Ubuntu, it made some screwy links between devices. But I have no idea how to resolve this... and there's no point in my mind to adding the DVD-RW to /etc/fstab until I can actually mount it manually to know it mounts successfully. Back when I installed Ubuntu 9.x on this machine, I never had any of these issues. It picked up the DVD-RW automatically, appended it to fstab during installation, and done. But 10.10 seems to be having some troubles my 9.x installation didn't.
I recently had one of my computers motherboard die and so I moved the hard drive to another linux machine so I could access the data. The hard drive is installed correctly and I've mounted several logical volumes on the drive ok, but I'm having trouble with the two volumes which were encrypted. The LVM Gui in Fedora is ignorant to any encrypted LVMs so I looked around to see if others have solved this problem and found the following command:
# cryptsetup luksOpen /dev/vg_delldesk/lv_home luks-fedora
My Logical volume container is vg_delldesk and the encrypted volume is lv_home - when I execute this command I get the following error:
Device /dev/vg_delldesk/lv_home is not a valid LUKS device.
I have access to the root partition from the old box so the config files are there to reference the old setup if needed. My current box is Fedora 14 x_64, I have dm_crypt mod installed in the kernel as well.
configure my raid devices so it can be started and mounted at start-up.

I'm trying to use the most-base install of opensuse 11.4 and so i'm using the text-only interface. I looked up some guides on using the 'mount' command but I'm encountering problems. I tried doing.
mkdir /tmp/flash
su
mount /dev/sdb /tmp/flash
but first off, I don't even know if sdb is my flash device, there's ~60 things in my /dev/ directory, and ~10 things that look like 'sdb' but I try anyway, and I generally get an error telling me that either /dev/sdb is busy, or /tmp/flash is busy but I wanted to check here and clarify first, how do I even know which /dev/ item is my flash drive? When I plug in my flash drive, no less than 3 new entries appear in /dev/ so, I'm a little confused. What do I do?

I have installed previous versions of ubuntu on this same computer but using the wizard inside windows.
I recently noticed a bug with ndiswrapper in Ubuntu 10.4 which would prevent the mounting of new USB device classes. This bug has been noticed somewhere else, in particular in at least one older Ubuntu version, but has been carried over. This doesn't seem to be widely discussed, or the solution worked anecdotally, but the problem is actually more general in nature. At the moment I found a workaround that always works, but I don't have a permanent fix.
The problem kicks in only after ndiswrapper module is loaded into the kernel. Devices of the same USB *types* that were recognized *before* ndiswrapper is loaded will continue to work. For example, an USB memory stick will be mounted fine if an USB hard disk had already been used at some point before ndiswrapper was loaded. However, if one plugs in any other new type of device, for example, an USB mouse, after ndiswrapper is loaded, the new USB device will not be mounted. The workaround solution is to disable ndiswrapper before introducing a new type of USB device by doing:sudo modprobe -r ndiswrapper
Then, plug in the USB device. After it is successfully mounted, do: sudo modprobe ndiswrapper
The corollary is that if ndiswrapper is loaded into the kernel upon boot-up, only USB devices which were present at the boot stage will be recognized. But performing the above kludge will allow new devices to be recognized.It'd be nice if someone can come up with a more elegant fix.
let's say this system has 3 hard drives. Drive #1 and #2 are RAID 0 and Windows7 lives there. It is a hardware RAID, not software.
On Drive #3 Ubuntu has been installed using WUBI - it boots up and works okay - but it does not see the RAID array.
Do I just need a linux driver to be able to see & mount my "Windows" RAID0 array? Or is this even possible? Can anyone point me in the right direction?
I posted a similar problem sometime last week...but a little has changed(mainly I can access my files now): I recently performed the auto upgrade to Ubuntu 10.04 and upon restart of my machine I am presented with 3 screens. The first is a simple "GRUB loading". The second is "mount: mounting none on /dev failed: no such device". The third screen is a series of initializations, i.e. /dev/sda1:
clean, (number of files), (number of blocks)
*setting preliminary keymap...
and so on until it hits the line:
*checking battery status
at which point it will cease loading until i press the power button. The next thing that occurs is it kills all the processes it just initialized and shuts down the computer. I read that this is likely a problem from loading the wrong kernel and I can get into my files (using a boot 9.10 boot key). The problem is I don't know what files to change in order to get my system booting the right kernel.
I have created a logical partition (/dev/sda5) and have formatted it with an ext3 filesystem and given it the label PHOTOS.
# mkfs.ext3 -L PHOTOS /dev/sda5
If I mount it to my /PHOTOS directory manually, it does so correctly. However, when I try to automount, it gives me this message:
# mount -a
mount: special device PHOTOS does not exist
I've entered this line in my fstab file:
PHOTOS/dev/sda5ext3defaults0 0
I'm just not sure what's happening; I've never had trouble mounting a filesystem before. Oh and it's a RHEL 5 installation.
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
I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.
How do I go about mounting a device if I don't know the file system type (e.g ext3, NTFS)?
View 4 Replies View RelatedRecently I installed a Linux distro (Pardus) which boots using initramfs. I am completely novice here. In the former configuration I used lilo to boot OpenBSD, Debian and W2k (it is easy for me to configure lilo to boot OpenBSD). But initramfs is a something completely new for me. As I understand it is a virtual file system with a standard directory tree and the information stored on that system is used (to boot the kernel?) to mount the true (physical) root device. The first question is how to properly describe a system (kernel image) booted with initramfs in the lilo.conf.
View 7 Replies View RelatedI'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69

sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

This is from ane external USB HDD I use as a backup device. I've tried formatting it as ext4 ane encrypting it from the command line
# mkfs.ext4 /dev/sdc1
# cryptestup luksFormat /dev/sdc1
which run without errors but an attempt to mount throws up the above error as well as saying - you must specify the file type (tried that) - and fails to mount. I've tried using YaST to format and encrypt it which throws up the same error when I run mount but actually does actually mount the filesystem Googling around has brought up info saying that it's probably a race condition brought on by invalid udev rules. I've got a (mostly) working system and the udev rules documentation leaves more confused than when I started.
Since May 12,2009. Our system lifekeeper has the error log "lifekeeper error: DEVICE FAILURE on SCSI device '/dev/add'", but it ran normally. Until last week, it failover to the standby server. The disk still running, the error still come out.
View 3 Replies View RelatedCentOS 5.3 has been running fairly good except for a slow ethernet connection so I thought I would upgrade to CentOS 5.4 to see if that improved things. I had previously changed fstab and menu.lst to use UUID instead of LABEL in order to insulate myself from partition label changes I wanted to make. This worked fine in CentOS 5.3. When I attempted to upgrade from 5.3 to 5.4 using the installation disk and telling it to upgrade rather than do a new install, the installation correctly found my root partition as /dev/sdb8. When I proceeded with the upgrade I received the error:
"Error mounting device UUID=cee298a0-9c47-4a3a-ac84-23db4d20edd5 as /. No such file or directory. This most likely means the partition has not been formatted."
But of course it has been formatted and is my / partition running CentOS 5.3 as I type. how to fix this to get CentOS 5.3 upgraded ? Di I have to use LABEL in fstab and menu.lst for my partitions,or perhaps just for my root partition ? Any other ideas why this is failing ?
How would I set a cron job to run every 7 minutes between 7pm and 11pm?
