CentOS 5 :: Need To Move Space From Root File System To Swap

Apr 7, 2009

I currently have a server with the default VolGroup00 that contains logical volumes for the root file system and swap using logical volumes LogVol00 (root) and LogVol01 (swap.) I need to take space from LogVol00 and move it to LogVol01. I have found documentation for increasing the swap, and the resizing the logical volumes. However in the documentation and the man pages it says that I have to reduce the size of teh file system on the logical volume I am going to shrink. I have found documentation resizing the logical volumes but not the file systems.

Ubuntu Installation :: Cannot Make Enough Space / No Root File System?

Jun 27, 2011

I've been trying to install ubuntu 11.04 64 bit on a partition next o windows 7 64 bit.When I use the default option (no matter how large I make the partition) I get the error message that not enough space could be created. I read this could e solved by defragmenting the hard drive which I did, but the problem persists.I next tried to partition manually but go the error message that there was "No root file system is de or something similar

General :: Move And Utilize Root /boot And Swap Dir To Temporary Location?

Oct 16, 2009

I'll start by explaining what my system layout currently is. I have Fedora 11 X64 installed on my system, it is an HP Dv9380ca laptop. My system has 2 hdd /dev/sda /dev/sdb. During the setup i set my home directory to reside on /dev/sdb. After booting i realized that my root and swap partition are part of a volume group name vg_sharpfed and are set in fstab as:

/dev/mapper/vg_sharpyfed-lv_root / ext4 defaults 1 1
/dev/mapper/vg_sharpyfed-lv_swap swap swap defaults 0 0

Output of Fdisk -l /dev/sda

Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x1aecda8d


My /dev/sda2 partitions is 100gigs and set as an LVM. Essentially what i am getting at is, if it's possible to temporarily copy / /boot and swap to my second partition, edit grub if needed and fstab to mount to the temp locations, format sda to ext4 create partitions for / /boot and swap partitions, then copy back the original directories edit required fstab to mount the original locations and no longer have them contained in a Logical volume.

CentOS 5 :: Move System And File Structure To New Box

Feb 7, 2011

I am new to Linux and not sure how to explain what I want to do, but I will give it a try. I have a system running CentOS 5.x on a system the is dying. Is there an easy way to migrate the system over to a brand new system that I recently purchased? I only have / and swap partitions, so nothing fancy; however, I have read that Linux is nothing like Windows when it comes to applications, and I could simply drag and drop files on the new server; however, I suspect that there is more involved than that. I hope I can just move the files over, and the system will boot; however, I am worried about new hardware on the new system. I am looking for recommendations to this issue. I am not sure if I have described it correctly; however, just point anything out that I need to change.

General :: No Space On Root After Large Move Operation?

Feb 16, 2010

I tried to move 2.7TB of data from my /var/webroot/ partition (4.5TB total in size). I left it to run over night, this morning when I came to check I saw that all data on / paratition is used up and no operations can be done because of the "no space left on device" message.


Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p7 911G 911G 0 100% /
tmpfs 7.9G 0 7.9G 0% /lib/init/rw


I freed up several hundred MB from / but still the usage is at 100% and I cant free up any more space or complete the transfer ?

250GB on / (root)
4.2TB on /home

Ubuntu :: Force System To Use Swap Space Instead Of RAM?

Jul 6, 2011

Is there any way to force the system to use swap space instead of RAM? I just upgrade form 512 to 1 gb. And when I installed ubuntu I give the swap space 1gb according to 512mb RAm requirement. Now I have 1 gb. When I use heavy applications i-e firefox, office, any game etc at a time the processing go to 100% and the RAM use 50+% of the memory. No swap memory will be use. Any way to use swap instead of RAM?

OpenSUSE Install :: Move Swap File To A 8GB SD Card?

May 24, 2010

I just got a new laptop and installed 11.1, and I want to move my swap file to a 8GB SD card I have. It seems to run very fast, so it will improve swapping speed. I created a swapfile with Partitioner, and I can delete the existing swapfile with GParted during a reboot - but I'm afraid I will make my system unbootable by doing that - don't I need to first tell OpenSuSE what swapfile (on the new sdb) to use? I'm pretty sure it will detect the new swapfile automatically during boot, but it might choke on a missing (old) swapfile.

CentOS 5 :: How To Cleanup Root File System

Jan 31, 2010

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

CentOS 5 Server :: Unattended Reboot With An Encrypted Root File System?

Mar 31, 2009

Centos 5.3 includes Ext4 and improved support for encrypted file systems but it appears to be aimed at laptop/desktop systems, in that a password must be entered at boot time.

Is it possible to have a server with an encrypted root file system boot up without entering a password?

Mandos will do it...
...by serving up the password from another server...
...to a client loaded into the initial RAM disk environment...
...but it's not available on CentOS, and is only in Debian unstable.

Is there a similar (or any) solution for CentOS?

In particular, I'm envisaging encrypted virtual machines being served passwords from their virtual host.

Alternatively, the data that *really* needs to be protected could be encrypted while the system core remains unencrypted. But then the keys to decrypt the file system must be stored in the unencrypted portion, so this is not an effective method.

CentOS 5 Networking :: Add "Root File System On NFS" To 5.5 ?

I'm trying to add "Root File System on NFS" to overcome some issues that I seem to be having putting VM's on an NFS share. I'm trying to configure the kernel, but can't for the life of me find the option to add Root FS on NFS. Is this removed from the configurator with CentOS 5.5/Xen, or is it configured already?

Ubuntu :: Incorrect File System Space Reported By System Monitor?

Apr 3, 2011

In System Monitor, on the File Systems tab, the "Total", "Available" and "Used" columns don't seem to add up, and the "Used" percentage doesn't seem correct either.

My config:
/dev/sda1 = 80 GB SSD drive, / partition.
/dev/sdb1 = 50 GB FAT32 partition of an external 500 GB USB hard disk.
/dev/sdb2 = remainder of the 500 GB USB hard disk encrypted using luks.

Screenshot: The /dev/sda1 figures don't really add up well, but they're close at least (how you get "50% Used" from any of those figures I don't know!).

However, for /dev/sdb2, they're miles off:
"Free" = 146.2 GiB
"Total" = 409.7 GiB
"Available" = 125.4 GiB
"Used" = 263.5 GiB

Ubuntu Installation :: Dual Boot Partitioning \ What File System Should Use For Windows Swap Partition

Sep 1, 2011

I am about to get a new laptop here soon and I was planning a dual boot like I have on my current laptop (Win7 and Ubuntu), but I have something special in mind. I looked around the forum to see if there was anything like what I had or if it was even possible but I didn't see anything quite like this.I was wondering if this was even possible, and if so, would anyone be able to tell me what filesystem I should use for my windows swap partition?

Ubuntu :: How To Move The Swap Location

Apr 28, 2011

can you move your swap to a new location after a install and if it is possible will it give any kind of performance boost if it is moved to a separate hard drive? I did this on my XP machine and it made a pretty big difference in over all speed of the machine and wanted to try this on my Ubuntu machine, assuming it will even make and difference in performances.

Ubuntu :: Move Swap From Pendrive To HDD?

May 30, 2011

Just moved/reinstalled my HTPC setup (XBMC Live + extras) to a 8GB USB pendrive to simplify future reinstalls and upgrades. Everything works fine so far and I've not had any issues setting up everything for my needs. The system is very responsive in use in XBMC (and other) but slow down quite a bit occasionally when doing to much at the same time.

Since a USB pendrive have its limitations, a concern I have is regarding the swap partition that is currently on the pendrive. Should I move the swap to a swap partition on my HDD to ease the stress on the pendrive; and could I expect any gain in performance? I have 2GB of RAM.

General :: File System Is Out Of Space

i just installed Fedora 12 (via vbox 3.1.4). stupidly i started with 8G and, of course, ran out of space on the / filesystem. i added 8G to the drive which now shows as 17G.based on the below outputs, it looks like i have 8G more space available on the drive. based on reading other posts it looks like i need to use parted to increase the size but not sure how to do that.

Ubuntu :: Swap Or Swap File On Flash Memory?

Aug 16, 2010

RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.

By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).

A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.

So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
