reducing the size of LVM. I did it by using the commands, lvreduce,fsck,resize2fs.After reducing the lvm size, my system is not booting...it is saying file system corrupted error.
View 1 RepliesI've got a fresh install of RHEL5 with updates installed running on a PC104. If the machine starts up the screensaver, I can't ever get out of it. The mouse pointer comes back up on the screen, but the desktop doesn't appear or a box to enter a password. I try to reboot X and get an error that X can't be started and it drops me to a prompt. I reboot from the command line and then I get the filesystem error and have to wait 2 hours while it scans.
View 4 Replies View RelatedMy friend has a HP Pavilion dv2699ea (dv2500 series - somehow *shrugs*) that has stopped working. It's a Core2Duo laptop with a Nvidia GPU. The unit is no longer under warranty. Problems first started a few days ago with the laptop showing corrupted graphics in Windows and BSOD'ing after a few minutes of use. I tried booting to an Ubuntu LiveCD which worked for a while before succuming and crashing as well. The freezing/graphics corruption/BSODing does seem somewhat heat related (CPU runs at ~95'c under load) however I believe that if it is heat related, then it's already damaged components inside.
Now the system has corrupted graphics on bootup[1], including booting Ubuntu[2], and neither operating systems will boot at all (Windows can sometimes get logged in before showing a black screen and becoming unresponsive. Ubuntu just looks like [3] after X starts). (See comment below for links.)
The fact the problem occurs both under Linux and Windows says to me this is not a driver issue. I have run Memtest which passed fine and none of this seems HDD related as I managed to get ~30GB of data off the system before it finally gave up the ghost.
She has been using it repeatedly without giving it adequate ventilation for years (i.e. on the bed, or on a pillow), so it's my opinion that the system board has probably warped over years of cooling/heating and that's causing this current problem. If that is the case, then I can buy a replacement system board and fit it myself, saving about £200 over the cost of an out-of-warranty HP repair. Of course, I don't want to make her spend £100 on a replacement part for it to be the wrong thing, hence asking for a second opinion here!
Hopefully I've covered all the bases here. I'm a former IT support guy myself, so I've tried all the dumb stuff (driver updates, examining memory dumps from BSODs [one 'unrecoverable hardware error', three relating to the graphics card], etc).
I recently installed Suse 11.1 from the Live CD on an older PC. Suddenly, when booting up yesterday, the system announced corrupted IPtables and didn't load KDE. After login, I tried commands like KDE, run KDE but the bash didn't understand the commands.
So I booted from the live CD, but I can't find an option in the install menu to repair the existing installation. The help in the boot-up screen claims there should be an install option, but it doesn't show it at that point, only after KDE has started from the Live CD.
Since I've already made some changes (newer firefox, downloaded thunderbird etc.), I would like to keep and repair the current installation, instead of a new installation.
I don't however understand enough about the automatic partitions I'm being offered in the installation menu to know what to choose to keep the existing files. I did choose the offered automatic partitions the first time, and have now several partitions, home swap and so on.
Second question: While 11.1 was still running nicely, I could not find the option to upgrade to 11.2 in the Yast menu (I don't know any batch commands, so I only use Yast for installation). Looking at the download sites on opensuse on the internet, I saw an update option, but when I tried to add that URL to the Yast repository, it somehow didn't work. I also didn't see a nicely packed .rpm or similar update package.
Third problem: I downloaded a newer version of Firefox and Thunderbird and after some tries got Yast software repositories to install them. But the Avira antivir tar.gz package I downloaded, did not appear on the Yast repository manager. Doubleclicking to Ark didn't work, and when I went to console and tried to run the install file in the zipped package, it wanted parameters, and I didn't know what to answer.
I have installed Red Hat Linux 5 and using it. But when I uninstalled one package and booting after that, I got the following error
Error 15 : file not found
I am using Ubuntu since release 8.10, but it is first time when i can`t solve problem
when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)
After reboot mine Ubuntu say:
Code:
Errors were found while checking the disk drive for /
Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery. I pressed "F" but that had help only for a boot and doesn`t really fix error :`(
Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error) Now i can`t even boot from that partition and even mount it from other linux system.
mine fdisk -l

PhotoRec recover most of my files, but i need complete partition.
I think that my external hard drive was either "unsafely removed" or powered off at a critical moment because when I tried to connect it to any OS Mac, Windows Ubuntu etc. It could not be read. I forget the Windows error message but the Ubuntu one was "mount error 2".In any case I downloaded testdisk asked it to analyze my hd and about half way through it said that the number of heads per cylinder were 128 and it more than likely should be 255 (or the other way around I forget which but I know the numbers are right). So I went and changed the geometry of the external HD such that the number is what testdisk told me was and the result is that my computers can read it but it seems that all the files are missing.
I used photorec and I have recovered all the files (unnamed and disorganized of course)So this leads me to the following question: is there any way I can repair my file system or access the files so that I don't have to go through the 16,000+ files rename and reorganize them again?
is lvresize with --resizefs options re-size the Logical Volume and then re-size the file system? i mean we don't need to use resize2fs?I looked at man pages but it doesn't explain this option.

I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).
I'm going to reformat my external drives to get rid of the crud that I've built up. (Crud being incremental backups, windows software, and similar things.)(I also want to get rid of the FAT32 file system that they use.) These are USB 1TB drives. The theory is that data is written to it once, but read back a number of times. (I also burn that data to DVD. If there was software that could organize 5TB of data on DVDs, I'd be using them.)
I"m trying to decide whether to use ReiserFS, Ext4, or another file system. Basically, I want something that:
* Won't get corrupted when the power fails;
* Can handle files that are 4+GB in size;
* Uses extends --- preferably without user intervention;
The Ext 4 file system of the partition (dev/sdb1) is corrupted. When I seek to repair this using the boot repair tool it is unable to resolve this. I admit that I don't fully understand the problem - except that I'm unable to open and use programs.

View 3 Replies View RelatedI have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.
I made 272 Photos from one book. Total size was 920MB. I used than gscan2pdf to create pdf document, and reduced there quality size. Result 116 MB. Than i converted it to grayscale [URL] with:
Code:
gs -sOutputFile=grayscale.pdf -sDEVICE=pdfwrite
-sColorConversionStrategy=Gray -dProcessColorModel=/DeviceGray
-dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH color.pdf
Result: 108MB
Is it anyway possible to reduce size more? Something like Google does with their books?

View 9 Replies View RelatedI recently recieved Ubuntu 9.04 Desktop Edition CD-ROM through snail-mail after requesting a copy online and I want to install it on my laptop, although I wish to keep Vista which is on it now.
My laptop has a 250GB hard drive. Although when in Vista this is represented as two separate drives each of 110GB, (C or ACER and (D or DATA.
Using the CD, I start the installation and everything is straightforward and self explanatory, until I get stuck at step 4...
Where I am told by the ubuntu installer: "This computer has several operating systems on it." (I'm confused now, I thought it had one, Vista.)
Beneath I am shown a bar representing my disk space which is divided between...
I am given the option to use the entire disk: 'SCSI1 (0,0,0)(sda) - 250.1GB ATA WDC WD2500BEVT - 2', (and from the mention of 250BG in the name I'm assuming this is one disk and not the two separate drives named C: & D: in Vista.) ...along with a warning - "This will delete Windows Vista (loader), Windows Vista (loader), Microsoft Windows XP Embedded and install Ubuntu 9.04". (The aforementioned "several operating systems" obviously.)
But I wish to keep Vista, so I select the option to "specify partitions manually" and am brought to a screen named 'Prepare Partitions', where there is a table somewhat like this:
I am then given the option for "New partition table", and if I select any of the bottom four devices I can 'edit partition' or 'delete partition'.
Selecting the device /dev/sda3 (because it is the one that I'm guessing has no operating system data on it, judging by the previous screen) and choosing 'edit partition', allows me the following options...to create a new partition size, to select what I want to use the partition as. (There are also two options for formating a partition, which is a checkbox, and Mount point. These are both greyed out.)
When I look at the 'Use as:' option, within 'edit partition', the drop down box allows me to use the partition in the following ways:
- do not use the partition
- swap area
- NTFS
- FAT 32 file system
- FAT16 file system
- XFS journaling file system
- ReiserFS journaling file system
- Ext2 file system
- Ext4 journaling file system
- Ext3 journaling file system
