I am a new Ubuntu user running Lucid Lynx and since some time suddenly my /home filesystem (mounted as ext3 on /dev/sda2) goes read-only.Is there a way to mount back the filesystem in the correct way without rebooting the system? I assume I won't be able to unmount the filesystem when I am logged on.

View 3 Replies View RelatedI have a Linksys WRT54G with the Tomato firmware on it. So the system running on the router is Busybox 1.14., which as far as I know is Linux-based. I want to update the busybox to the newest version, using ipkg which is the only package manager it has installed on it. By the way, I use telnet to access the router. So I use # ipkg install (the url to newest busybox release) but at some point it stops and says:
mkdir: cannot create directory '//opt/usr/': Read-only file system
so what can I do? How can I make the filesystem read-write?
I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?

I have never seen anything like this before. Starting up today my usually completely free of clutter desktop is showing all of my home directory folders!If I delete folders from the desktop, they are also deleted from my home directory. If I create a new home directory folder, it also appears on my desktop. In effect my desktop has become my home directory and I don't like it.

When I click on "Places --> Desktop" it's as if I've clicked on "Places --> Home Folder" (the "File Browser" directory opens, the location is set at "/home/rj", and the title at the top is "File Browser").
Elementary stuff for a lot of you, I'm sure, but I'm blanking on how the Desktop folder can be restored to what I'd like it to be (basically empty, except for a "Downloads" folder), and my folders and files kept off the actual desktop (except for the "Downloads" folder).
My usually blank and happy background suddenly lists the things in my home directory. Well, it has icons for them.I have tried the gconf-editor, apps->nautilus->desktop drill, but the stuff is still there. Showed up suddenly about a day ago

When I mount on the server its self, it works fine. But on other computers. Such as my windows 7 machine, the connection times out. It seems to make the inital connect, then none after that. (The windows 7 machine does have the NFS files installed).
View 3 Replies View RelatedWhat is the recommended filesystem to use when creating a home server/nas?
I'd be sharing files using SAMBA, DLNA Server or some sort of streaming. I'll have two win7 laptops, 2 ubuntu desktops and ps3 accessing the files. Most of the time the server will just 75% read from 25% writing.
Would ext4 be an ideal?
why my df -h command is telling me I'm missing 18G?
***
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_aikifedora-lv_home
357G 272M 339G 1% /home

This was 'df -h /home' straight after a fresh install. It says it's 357G in size, but even though 272M is in use, it's telling me I have only 339G left available. Where did that extra 18G go?
I'm looking for the best distributed filesystem to share my home directory among all my computers, and I'm interested in what advice I could get here.
Here are my requirements:
1) It must be completely POSIX compliant, because I've noticed that many programs will break if not.
1a) Must support file locking (i.e. flock()) preferably sharing lock advisories between the clients
1b) Must support hard links, and be able to recognize a hard link connection by looking at the number of references
2) It must have encryption, and security suitable for it to be exposed to the internet.
2a) I would like to use password-less authentication. Preferably SSL client certs (HTTPS style). Static keys (SSH style) are also fine. I would begrudgingly accept a password authenticated system if it used a fairly secure challenge/response algorithm if it met all of my other requirements. (Extra points if it supports PKCS#11 and thus supports smart cards)
2b) Encrypted traffic must be an option.
2c) No thanks to kerberos. It was too annoying to maintain when I tried it before and I don't like passwords.
3) Preferably, it should be stable and fairly easy to maintain.
4) Optionally, it should be tolerant of network drops, and reconnect automatically as needed, because my laptop wireless is a little flaky sometimes.
have a Debian server which I use to hold my home directory for my user account. I used to use Windows 7 and connect to my /home/username directory via Samba which worked great. I could access all of my files as if they were sitting on my local PC, but they were actually sitting on my Debian server.
Now I have decided to give Ubuntu 10.10 a try (looks promising so far!).One thing I'm not sure how to do is to mount my home directory from my server! I am able to open an sftp connection to my server, but not able to access them natively as they were /home/username on my local machine.I'm assuming I need to mount my home directory somewhere in my fstab before it starts up, but which protocol should I use? I'm used to using windows networking, but am trying to get more into linux.Should I use NFS?
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
I am trying to write a file to a SD card in my card reader.When Ubuntu first boots in and I open up the SD card It gives the option to create folders and files. However after a second or two the window closes and then will only let me vew the files.Does anyone know how I can fix this so that the SD card is able to be written to?The lock is not on the SD card, and under permissions it states that I have permission to create and delete files.I am using an up to date version of Ubuntu Lucid Lynx 10.04I have tried searching for a solution but cannot find anything relevant that works
Edit :
output of syslog from removing and reinserting the SD card

I installed fedora 13 64 bit and it works great but I encountered several issues when setting up guest OS with KVM. The problem seems to be related to selinux. But let me first ask question about logical volume. By Default fedora created logical volumes:
[Code].....
"If you expect that you or other users will store data on the system, create a separate partition for the /home directory within a volume group. With a separate /home partition, you may upgrade or reinstall Fedora without erasing user data files." seems to suggest I have to create a separate physical partition and assign that to /home. But reading elsewhere it seems to suggest logical volume acts like a partition. My goal is to make it easy in case fedora is hosed and I have to re-install it without affecting /home where my cirtical data resides. Given above do I need to create a separate physical partition or I am just fine?
I have a second hard disk that originally had windows and all my data. Windows is hosed but I can see my data from within Fedora and Windows is gone and I created created new partition in its place which used ot be the C:/ drive appears as 53 Gb filesystem. My data which was originally D drive appears as 215 GB filesystem. As given in [URL] I want to create a new logical volume in 53 Gb filesystem which I want to use as space for virtual disk to install guest OS's in KVM. Currrently 53 GB filesystem is mounted as /media/3467BH89JK789 but this does not work well with KVM. how do I create this logical volume out of 53 Gb filesystem partition and add proper selinux info and do I add to vg_vostrolx volume group and in a different volume group?
I am following a gtk2-perl tutorial, so I wrote the test program, installed gtk2-perl, and got this error:

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.
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.

I try ext3:

dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?
