Slackware :: Options For Enlarging Root File System?
Feb 16, 2010
I need to enlarge the root file system on a Slackware 13.0 32-bit system; it's in a simple logical partition (/dev/sda6) -- no LVM, mirroring etc. This might be a good opportunity to change from ext4 to jfs, too.Routine procedure, no? No!First off I booted Knoppix 5.31 but found it doesn't have ext4 support (no efs2ck and running fsck results in "fsck.ext4: not found").So I booted Slackware 13.0 32-bit CD-1 only to get the same as with Knoppix.I do have a GParted-liveCD 0.3.4-11 but have had mixed experiences with it so am reluctant, despite having backups.

I recently cleared out some old partitions, and "/" was getting full so I made it bigger. It went from about 2Gb to 7Gb.
Now when I boot into my OS I get a dialogue saying:
Code:
The volume "Filesystem root" has only 0 bytes disk space remaining
You can free up disk space by removing unused programs or files, or by moving files to another disk or partition I don't see how this is possible. If anything it should have more free space than it had before. how I might go about diagnosing this issue?

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.

Fsck is not check any file system which are not root file system at boot time.
Normally it run: /sbin/fsck -A -R -C -a
But this command doesn't do anything.
I've tried to strace it, and looks like this:

Started slackpkg upgrade-up and went to bed. Woke up to find the power had gone out during the night. The computer booted up, but displayed a message that said something to the effect of, "Error occurred during root file system check. You will be given the option of doing maintenance......"I can get to a command prompt, but regardless of what I do a message pops saying it can't find libblkid.so.1

I have considered a range of choices, but at the end of the day the choice I make can quite easily put into a situation that requires even more thinking.
The idea is to have an enormous file system for SAMBA that can scale from terabytes to petabytes. Such as a single directory with say 4 million MP3s in my iTunes collection. iTunes cannot use multiple drives easily.
There are lots of vendors that have offerings galore, I wanted to see what can be done with a roll your own approach.

Is there some file in Linux that enumerates and describes mount options for file systems like /etc/services describes ports?

You know the system mail message that Pat leaves root welcoming them to Slackware and other things.here are some good things in there. I wanted to know how I could copy that so other user on the system could read it in a text file or something

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.

When I set up my current Debian desktop system ( currently squeeze ) in 2007 I allocated only 8.4G to my / partition. Now I find it is getting too crowded with only about 580M free space (worked around CD & DVD burning by creating a /tmp folder in my /home/username folder). My current plan for fixing this is to use gparted running from a live-cd. I will first delete my swap partition and my /home partition then use gparted to enlarge my / partition to 20G. Next I will recreate & format my swap and /home partitions and restore the contents of my /home partition from backup. I will still have lots of room to spare in my /home partition. My system has no extended partitions. My hd is 250G total. I know this will change the UUIDs of the two new partitions but am not sure if it will change the UUID of the expanded / partition. I expect it will. My next step will be to edit my /etc/fstab and put in the new UUIDs which I will get by running blkid /dev/sdb. My backup drive is an ide drive, /dev/sda. My question is am I likely to run into boot problems with grub2? Should I chroot into my / partition and run update-grub before I reboot or wait to see if it will
reboot first?

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% /

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 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 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."

Information on the net seems very sparse or outdated for how to go about booting to a RAM disk. I need to be be able to boot a PC without a hard drive in it. I want to be able to PXE boot a PC and supply it with a RAM disk image that also contains the contents of the root file system (obviously stripped down enough to keep the file size small and the boot up time fast).What I have gathered so far is that I need to extract the contents of the initrd.img file, add files as necessary, and repackage the initrd.img file. What I get confused on is how to configure the kernel line parameters to tell it to boot to RAM and not the hard drive and how to go about modifying the init script in the initrd.img to not switch to the hard drive for the root file system. I can't find anything on the net that describes concrete steps on how to go about accomplishing all of this. I'm aware of the existence of Live CD's, but I need to be able to boot the PC without relying on a hard drive, CD, or any other external media. It needs to get all of its contents from the PXE boot server and boot to RAM only. I have the PXE boot side configured successfully. Also, putting the root file system on a NFS share is also out of the question.
