Server :: SAN Mount Going To Read Only - FS Errors
Mar 28, 2011
I have a server that has a Fibre Channel mount that is having issues. When I can in this morning I found that it had switched to read only. Now looking through /var/log/messages I see that there are errors reported on the disk. I know that i will need to run fsck on it, but I do see lines about the device mapper failing for mpath0 first, which is the device which is mounted. I am wondering if someone can take a look and see if this is just a drive issue, or an issue with the fibre channel connection.

I have a Windows 2003 server with fiber attached volumes (NTFS) that I would like to mount readonly on a linux system to back it up to tape. The fiber device will allow me to present the volume R/W to one host and R/O to another, however, the R/O system doesn't see any of the changes made by the R/W server. In other words, how can I make a readonly volume refresh, scan for changes, or update without un/re-mounting it?
Is the "mount -o --bind" option what I want? From the MAN is doesn't seem right... the option "sync" seems slightly more promising but I think I'm just grasping at straws here. The best I have come up with is a cron job to unmount then mount the volume periodically.
The install 9.10 CD has a bug and I can't continue with the install after booting up and selecting the language. My screen ends up having vertical green bars. Also get a bunch of sr0 read errors. I used the same CD to install on my laptop, which went well. I am currently using 9.04 and it work flawless

Recently my Ubuntu system decided to crash. Sometimes the mouse freezes, sometimes I just can't open anything, and other times I can access the terminal but can't write. I can open files as read only both in my /home partition and in /var/log, but I can't write at all. Sometimes I get Bash: input/output error. I *can* "ls /proc", if that makes any difference.
I find that if I reboot, the problem goes away for a few minutes and then reoccurs. I can read/write to my other (windows) drive, although when I did a chkdsk in win7, I get a "An index entry from index $0 of file 25 is incorrect" message. Is the disk failing? Just a few bad sectors? Maybe the filesystem is corrupt? Why can I read but not write?
I have a VIA EPIA motherboard with a VT1612A integrated soundcard. With Linux Kernel 2.4.22 I have no problem reading from the soundcard using a custom application. With Linux Kernel 2.6.30 I am getting read errors that present themselves as corrupt samples.First, a small, pseudocode version of the application ...
I'm designing an embedded USB device. When I connect the device to the computer, I get the following messages:
usb 1-3: device descriptor read/64, error 2 usb 1-3: device descriptor read/64, error 2 usb 1-3: device descriptor read/64, error 2 usb 1-3: device descriptor read/8, error -71 usb 1-3: device descriptor read/8, error -71 usb 1-3: device descriptor read/8, error -71
Note that other USB devices work fine. I am fairly certain that the problem is with my hardware. I'd like info on what these error messages mean to help my debug. Searching Google I wasn't able to find any explanations about what these errors mean exactly.

I've got a Lucid system (normal Ubuntu, not any of the derivative distros) which has been throwing up the following error message this morning when trying to boot:
Code: error: couldn't read file. error: you need to load the kernel first.
I have a problem in my ubuntu 10.01 that it can't load a drive/volume in ubuntu. When I tried, it said: "Unable to mount location Error mounting: mount: /dev/sda1: can't read superblock". And when I boot my pc with 'Windows', it said : "UNMOUNTABLE_BOOT_VOLUME" under a blue screen. What can I do to solve this problem?
I am using 9.10 Karmic Koala Oct 2009 release. Gtkpod does not show my ipod touch, and I can not mount the ipod. I realise there were problems with the ipod touch syncing/mounting but gtkpod has the touch option, and I have all the files from synaptic for using an ipod touch. When I run gtkpod its just blank, no music files show up. If I click load ipod I get the error:
I have two mount points that used to work. I have them defined as cifs shares in fstab, and they map to a Windows machine, which I am able to ping from my Fedora machine, but for some reason I get a mount error 2, and the destination is not accessible. The man page doesn't really give any troubleshooting steps. Since I am mounting by IP address (which as I said has worked before), nothing has changed, although the IP address did change, which I updated in the fstab file to the new IP address (and since I have reserved this new IP address so it can't change again!)
I ran a test and shared a folder from another one of my computers, and added a line in fstab to auto-mount that, and I get a "permission denied" error 13, which is different than the error 2 I get on the other 2 shares. What should I be looking for as far as actual connectivity between the machines? I have verified that the windows machine is on and I can access the same shares from another computer.
Update: Added the host and IP address to my hosts file, and replaced the IP address with the name, and still get the same error. Also, the share name has a space in it, so I replace that with a "�40" space character (which worked in the past). I tried replacing that with an actual space, and putting quotes around the URL, but then I get a "bad URL" error.
This appears to mount correctly, however there are some filenames on the server with the bullet character() in their name, and by mounting via fstab, the bullet shows as a question mark, but mounting from nautilus shows the bullet.
Anyway I can mount with fstab, and have all characters show properly in the filename?
In this case what is the return value of mount. I want to run e2fsck only when either mount fails or mount succeeded but with errors . Is there some way to detect this situatin "mounting fs with errors" in code/script .
What can I change in my pendrivlinux as to having it to mount an additional, mnt/win_e/, usb as read-only? I seems like if all usb thumbdrivers are mounted writable in mandriva. It must be possible to change this somewhere.....but where?
I am having problems with an old laptop I have. It had windows xp on it, and after loaning it to a friend it wouldn't boot up. I decided to try linux, but I'm having problems loading it. If I try to run the liveCD it halts because its unable to mount root. If I try to install it just doesnt work well (will stop at different points).
So I figured a mem test would help. I am running the test, currently its on test #6, but it is coming up with a ton of errors. Does this mean I need to replace the RAM?
If so, this is the computer I have. Will this RAM work? I've been out of the tech game for awhile so not really following hardware anymore, and just want to double check.
I can NOT mount my CDROM. I see several under the /dev folder cdrom, cdrw, dvd, scd0, src, how do I kow which drive to mount? I would like to load KDE fom a slackware disk,
I recently formatted my memory stick in windows. It works properly in windows. I have a dual boot with ubuntu 10.04 and the usb automounts in read-only mode. I cannot write anything to the usb stick in ubuntu. sudo chomod does not work.
sudden of all all USB drives and sticks I put into a PC will not mount with read/write permissions (they did before). I can still copy to them, but only when I am root. I am on Maverick I've noticed though that if I run disk utility, then UNMOUNT the partition, Check File System, Mount the partition back, I get read/write access..
While I had the case open to swap out a network card I thought I would drop in an old USB card (previously used with no problems on a machine running Debian) however on boot I'm now getting some errors showing up. The card has been sitting around for a while so it could be an issue with the card.
I can install the system, start setting it up, but eventually the system will halt with "Read only" errors, Input/Output errors on the drive the Distro is installed on and crap out. everything is working fine in Windows 7. It is just linux, seemingly. I've checked the hard-drive, memory, etc. I'm at an utter loss as to what is going on!
so what i did first was obviously use wubi to download and install ubuntu. after a 14 minute download, i was finally ready to proceed with the installation. i was excited, however, little did i know the installation would soon be a complete train wreck with little children aboard.here i am, sitting down, rebooting my LAPTOP computer (Acer Aspire 5336, Intel(R) Celeron(R) CPU - 900 @ 2.20 GHz 2.19 GHz, 3.00GB RAM, 64-bit operating system -- bought it at walmart because my desktop is still at my parent's house),and then i choose to boot up ubuntu instead of windows 7. everything looks like it goes fine so far.
there were a few errors but it went by so fast i could only read the "error" part. i wait for the installation thingy to show, but it doesn't! the screen goes completely blank after a few more words show up and disappear all in a blink of an eye, so i wait a very long time. it shows a purple screen, and asks me to choose a boot thing or w/e. i choose linux (there were other options like windows 7, linux recovery, i forgot the rest), then it just restarts the computer and i choose ubuntu and it does it again, however it never shows the purple screen!
I recently got a computer donated to me for free from my Computer Science class, as the teacher couldn't figure out what the problem was that was preventing him from booting to the startup screen (all I could figure out was that the slot the memory card was in was bad, so I switched slots and got it working). The hard drive on the computer was wiped with a disk nuker called DBAN. Now I would like to install a Linux OS on the computer, but whatever disc or distro I try gives me similar "unable to read" errors. I would like to know if there's anything software-wise I need to do before attempting to replace any hardware. An example of the error I'm getting is as follows (using a mandriva livecd):
/etc/rc.d/rc.sysinit: line 1281: /var/log/dmesy: Read-only file system SQUASHFS error: sb_bread failed reading block 0xa6e58 SQUASHFS error: unable to read cache block [29b963ea:782] SQUASHFS error: unable to read directory block [29b963ea:782]
Anyone know what I need to do to get this fixed so that I can install a Linux distro?
After a motherboard crash I have a problem. i have a LVM2 partition that is placed on 2 different physical disks that i need to read. Since I am pretty new to Linux/Fedora a friend helped me to install the system on my old system so i am not sure if the disk is formatted as ext2,ext3 or xfs. How do I mount these 2 disks to be able to read the files? when i run fdisk -l I got:
I am completely new to Linux and picking things up slowly. I have a question about mounting my NAS NV+. When I mount it, i use the following commands when logged on as user "matt":
sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Matts /home/matt/GRUMPY/Matts sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Torrents /home/matt/GRUMPY/Torrents sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Media /home/matt/GRUMPY/Media sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Programs /home/matt/GRUMPY/Programs
GRUMPY is the name of my NAS by the way! It mounts properly, BUT i cannot delete or rename files, so basically the user "matt" has read only privileges, and root has ownership of the mount. How do I go about mounting these so that user "matt" has RW privileges?
When I log on as root user and mount them, I can read and write as required, so this has led me to believe that my problem lies in my permissions for matt when mounting them... I posted on the netgear forum and was asked to try and mount using the following command:
I'm currently setting up a laptop for my grandparents to use. They have never used a computer before, so I'm trying to make this as fool-proof as possible. The system will be setup with Ubuntu 10.10. In order to save them the hassle of having to unmount USB drives before disconnecting them, I would like to have all USB drives auto-mounted as read-only (possible use cases for now only include them getting data from people, not them copying anything to the drive). I have so far found that gnome-volume-manager is responsible for the handy auto-mount, but I didn't find any way to set options, like always mounting drives read-only.
I have 4 partitions. One is Ext4 for Karmic, one is NTFS for WinXP, and the other two are Ext4 where I keep all my stuff.When I boot into Karmic and open Nautilus, none of the last three are auto mounted. When I click on one of them, instead of a window popping out asking me for a sudo password, I get a message as shown below.f I try to mount via sudo in terminal it works, but the files for me are then all read-only. Again, if I open Nautilus as root, all works fine.What I want is the following:- for all 3 partitions to automount on startup;- for all 3 partitions to be owned by me and not by root.I tried editing /etc/fstab, but to no avail. Neither did running "chown" help.
/etc/fstab: # /etc/fstab: static file system information. #
