I want to make a bootable DVD and nothing I read works. The syslinux.cfg seems to be the most important. I get most of my info from www.syslinux.com of course and Arch linux's page. Nothing seems to work. I am using fedora codre 17 right now. Bill

I have just jined this list. I can't seem to boot from a USB and my BIOS recognizes my sandisk USB by name. I can't figure out what modules to use. mbr.bin and parted is one method. Then syslinux is run and a syslinux.cfg is needed. Is this sufficent for syslinux? LINUX bzImage //kernel image INITRD initrd // initial ramdisk to boot a small liinux system on a USB. Bill Thanks for any

I hope this is the right list. I have created an ext2 filesystem and removed the dir_index feature. I don't know if this kind of experimentation is going to help me learn something about filesystems or not. Well what is dir_index? Then I ran e2fsck -f -v -pD and the /dev file. Now what did I remove? Htree. I guess it can always be put back and it's on an experimental filesystem.

Thanks for you help. I also tried adding some other informations as you suggest: I can also take into account: - "Reserved block count: XXXXXXX" from tune2fs that gives me the number of blocks reserved for root - Reserved GDT blocks: XXX But I didn't thought about the FS journal. How can I gather information about it? (it's size and any other information?) 2013/9/16

OK. Thanks for the journal information. I thought tune2fs -l and dumpe2fs were the same. In reality it's almost the same but not entirely ^^ I hear you about all the internal mecanisms that make the FS working or give it some features, and I do understand that it takes some place on the disk. However what I don't understand is why the number given in the "available column" is

Hello guys, I have some difficulties to understand what really are the numbers behing "df" and tune2fs. You'll find the output of tune2fs and df below, on which my maths are based. Here are my maths: A tune2fs on an ext3 FS tell me the FS size is 3284992 block large. It also tell me that the size of one block is 4096 (bytes if I'm not wrong?). So my maths tell me that the disk

Hello, As a Virtuozzo users we have majority of our diskspace formatted with -i 1024 -b 1024. Lately I discovered that on CentOS 4.6 ext2online barfs when I try to grow such filesystem. Running it with -v -d, it prints lots of lines like: ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: 873646830 is a bad size for an ext2 fs! rounding down to 873644033 ... group NNN inode table has

Hi, I have a system with an ext4 filesystem with its journal on an other device (an SSD). Now this SSD dropped of the sata bus so the filesystem went r/o. I would like to remove the journal but it says it can't because needs_check is set. I can't run fsck because the journal is not reachable. Is there any way to solve this? I understand I lost any pending changes in the journal. regards

All, We are encountering spurious errors with ext3. After some period of heavy IO we may see messages similiar to: EXT3-fs error (device cciss/c0d0p5) in start_transaction: Journal has aborted When this happens the filesystem is remounted read-only. If it's the root filesystem the system becomes unresponsive and must be rebooted. An fsck on the affected filesystem shows lots of corruption.

Today, I had to uncleanly shutdown one of our machines due to an error in 2.6.28.3. Durin the boot sequence, the ext4 partition /home experienced a journal replay. /home looks like this: /dev/mapper/volg1-logv1 on /home type ext4 (rw,noexec,nodev,noatime,errors=remount-ro) Filesystem Size Used Avail Use% Mounted on /dev/mapper/volg1-logv1 2,4T 1,4T 1022G 58% /home Filesystem

hello everyone. i guess this has been asked before, but haven't found it in the faq. i have the following issue... it is not uncommon nowadays to have desktops with filesystems in the order of 500gb/1tb. now, my kubuntu (but other distros do the same) forces a fsck on ext3 every so often, no matter what. in the past it wasn't a big issue. but with sizes increasing so much, users are

This lays the groundwork for setting Root and RootBackup onto individual partitions for multiple disk installations in the future. Install, removal, upgrade testing has been performed and all seems to work at this point. --- scripts/ovirt-config-boot | 15 ++++++++------- scripts/ovirt-config-storage | 28 +++++++++++++++------------- scripts/ovirt-config-uninstall | 2 ++
