Fedora :: Root File System Out Of Memory?
May 22, 2011
I have worked in linux for a long time but never managed the system until I got my own server, which is running Fedora 14. I have a 3 TB Drive and apparently can only handle 2 TB. At least the Disk Analyzer is telling me that 2TB is 100% max capacity. Also viewing disk analyzer, I am only using 50GB of my 2TB but I am out of memory in the Root file system. If I run df -h, I get he following:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_dev1-lv_root
50G 40G 7.2G 85% /
[code]....

I am interested in making the root file system is read-only. I've moved /var and /tmp file systems to another partitions. There are two files in the /etc directory that need to be writable.
These are:
I've moved this files to /var and linked it. I've added command to the /etc/rc.d/rc.local file:
That's it. Are there other solutions to make the root file system is read-only?

I have a fedora 14 system. I booted a suse installation that existed on an external harddisk and wanted to access my original fedora user home directory using non-root preveliges(so that i can use the gui file manager), so I searched on the internet and made a command to (chown -R mysuseUser:Users *) thinking that it will only affect the current mount permissions (not permenantly) put it did change the file system... i realized and cut it in the middle but some corruption was done. and then my fedora gui login screen was missing any username. tried to fix that by going to my fedora and executing chown (once using --from , and once without --from) and changed all root file system recursively to be owned by root and then changed my /home/myuserName ownerships all recursively to be owned by myUserName after that... still the system is corrupted..... when i login to genome i have several crash messages (gdiskutility is one of them) and networking is disabled (i cannot connect to neither wireless nor wired nor wireless broadband). also when i plug USB/esata harddisks nothing happens
now i can only do work from my external harddisk`s suse linux. what can i do to restore my system ? I have a previous dd image of my entire harddrive, but it is more than one month old and also I don`t want to do a restore to my entire harddrive.. can i clone some ownerships from files in dd image to their corresponding ones in my fedora system ? if so, how can i even mount a dd image ?

I have a LiveCD (DVD with many linux versions on it) and no other software on my computer at the moment. The computer specs are as follow:
When I use the live cd I get the following message: Cannot find root file system
I have tried the suggestion along the lines of:
Then it either goes back to Bash or I get "Kernel panic - not syncing: Attempted to kill init"
Then my install just freezes there and I need to restart my computer.

I have tried to write my files to 2 (2GB each) USB sticks and both turned into a Read-Only-File-System. Then I tried with my Memory Stick Duo and it also turned into that. So I give my last try with my SanDisk HC Memory Card (from photo camera) and resulted the same. I can copy the files of those portable storages into my HDD fine but not write into them or delete any files inside those portable storages.

To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?

I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.

I just installed Fedora 13 onto a "new" (to me) box, and everything seems mostly fine, except that I only seem to be able to use about 900.2 MiB of 991.4 MiB of RAM memory, according to System Monitor. I haven't set up a swap partition yet, so the problem became very, very, very obvious. When I get to about 890 MiB usage, everything goes very quickly downhill, locking up, etc. The peak I saw was 900.2 MiB. What's going on? Does this have anything to do with the system being 64-bit? Might the memory be bad?

the terminal and logged in as root i was changing file permissions and happened to change the root folder to 700. Now my icons have gone and i can't even access the terminal.
I was just wondering if it is possible to go to rescue mode using the cd and restore all the appropriate file permissions to root/ users if possible

I have been using Ubuntu 9.10 Desktop version for around 1 month then i stoped using after installing windows 7, as I knew that there were the 10.04 version coming. So when it was released i went to torrent download the file and burned it on a cd. After that i insert the cd and use the wubi installer in there as i want to install them side by side. so after installing ubuntu i restarted the system and got into it. After a few minutes it appeared this error message "Not root file system is defined. Please correct this from the partitioning menu." So i was expecting it to be downloading problems. I went on to ubuntu website requested for a CD and it came today. So i inserted the cd did the same thing again.

Is it possible to run fsck on the root file system?
My Ubuntu 10.04 seems to be checking it's fs at boot...
It shows that the file system is in use and can get severely damaged!
Or the only possibility is to run it from a live CD?

My current installation setup has a separate partition for /, /boot, /home, /tmp, /usr, and /var. The problem I have is the root partition / is 98% full (4.3GB full). Cleaning temp files and log files won't help since they are on their own partition (and clean). I've removed all but two linux-images. Linux images seem to run at a size of roughly 105M. My root partition is 4.6GB. I can't seem to find any other options for cleaning up space on this partition. I have no idea what is taking up 4.6GB of space.
Disk Usage Analyzer has not been helpful since I have not been able to reconcile 4.6GB of memory with what it claims the total size of the remaining directories occupy. I've tried localepurge, gtkorphan, apt-get clean, apt-get autoclean, apt-get autoremove. I've removed all packages listed under Status -> Not Installed in the package manager. My root file system is still 98% full (4.3GB full).

Classic partition problem apparently. What do I do? the 11.04 wubi doesn't give a lot of installation options, so i just selected C drive, and gave it 10GB of space. instilled it, and when it goes to the desktop menu, that pop up appears saying No root file system is defined. Please correct this from the partitioning menu
In dual booting with XP. what do I do?

I would like to know if there is a way to do an unattended check on the root file system on my servers, *and* send emails in case of errors.
I know you can schedule a root file system fsck during boot time - but the root file system will be mounted read-only - so if fsck finds any problems - it can't email away a warning, or write the result to a file - or can it?
Essentially I would like my servers to do a self-check of the root file system periodically - and to email me if it fails. I just can't think of a way to get it done.

I have a problem that is probably simple, but have not yet found the answer on any forums or by Googling. First my system specs:Tyan 2610 motherboard w/ 2 x PIII 9334 gig PC133 SDRAM
1 x 5 gig hd (system)4 x 500 gig hds w/ 3Ware 7500 controller set to RAID 5, (1.5 TB) mounted as /homeCentOS 5.3 running my smb and nfs mountsMy problem is that I have run out of space on my / (root) file system, (the 5 gig). Since I am planing to rebuild my file server with larger hard drives, (2 x's 60 gig SATA's set to RAID 1, 6 x's 1.5 TB at RAID 5), within the next 2 months, I would like to try to clean out any unneeded crap rather than adding a hard drive and expanding my root file system. I have done the following:
Removed old unused kernels
cleaned up /var/log/
cleaned up /tmp

I had Fedora 13 64 bit before which was correctly reporting memory as 4GB. After I wiped off Fedora 13 and did a fresh install of Fedora 15 32 bit, the memory is reported as 3.2 GB in the system Info and also in free -mt command code...
Where is 600MB memory gone missing? I checked the BIOS setting and it correctly says total memory is 4GB.
The hardware is exactly same and I did not change anything.

I would like to start off by saying this: I am very new to Linux, and this is my first time installing it, therefor I am having some very newb-like issues. Please bear with me.I am currently at step five of the installation process of Ubuntu, and I clicked on the partition which I have set aside to install Ubuntu onto, but when I proceed by hitting forward, I get the following error message:"No root file system is defined.Please correct this from the partitioning menu."My question to the community is, how would I correct that? How do I turn my 20GB partition into the root file system?P.S. I searched the forum for this issue, and being that it sounds so simple, yet I found nothing about it being previously asked, I feel sort of dumb....

I'm having a problem and it seems like partitions during the dual boot install.
Here's EXACTLY what I get...
Menu: Allocate drive space
Erase and use entire disk
X Specify partitions manually (advanced) [X denotes I chose this option]
I have 3 partitions on my gateway laptop...
[graphical bar across the top]
sda1 NTFS - 10g - weird partition w/recovery software or something from Vista
sda2 NTFS - 140g - Windows Vista
47g FREE SPACE [this is where I want ubuntu]
[Code].....
I click "Install Now" and I get this error:
"No root file system is defined. Please correct this from the partitioning menu."
