similar to: Ext3: changes to increase the speed?

I've been thinking recently that we should re-enable DIR_INDEX in mke2fs by default. When it first came out, we had done this and were bitten by a few bugs in the code. However, this code has been in heavy use for several thousand filesystem years in Lustre, if not elsewhere, and I'm inclined to think it is pretty safe these days. Likewise, RHEL/FC have had RESIZE_INODE as a standard

I am running into performance issues with ext3. Historically we had our image files (pictures of cars, currently 5.3 million) sub divided into a directory structure [0-9]/[0-9]/[0-9]/[0-9], where we would take the first 4 letters/numbers of the file name and use that to put it into this structure. Letters [a-cA-C] would become a 0, [d-fD-F] a 1, etc. As the file names used to be based on VIN

We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

I'm setting up a new fileserver. It has two RAID controllers, a PERC 3/DI providing mirrored system disks and a PERC 3/DC providing a 1TB RAID5 volume consisting of eight 144GB U160 drives. This will serve NFS, Samba and sftp clients for about 200 users. The logical drive was created with the following settings: RAID = 5 stripe size = 32kb write policy = wrback read policy =

I made a filesystem (mke2fs -j) on a logical volume under kernel 2.6.20 on a 64-bit based system, and when I try to mount it, ext3 complains with EXT3-fs: dm-1: couldn't mount because of unsupported optional features (80). I first thought I just forgot to make the filesystem, so I remade it and the error is still present. I ran fsck on this freshly made filesystem, and it completed with

Hello! I read the Split access and Load balancing sections into LARTC (Chapter 4). However I have one gateway only and the LARTC says about 2 links. I need to know how to make a load balance with my links. Thanks in advance. Eriberto - Brazil

All, I'm requesting comments from the expert readers of ext3-users on these notes for tuning ext3 for performance. Most helpful would be feedback pertinent to RHEL 5; as XFS isn't supported under Red Hat Enterprise Linux these items are an attempt to match XFS performance with ext3. These items were culled from a number of sources. Will they be effective for achieving the performance

Hello, How to upgrade existing ext3 partition to new features? Moved from RHEL3 to RHEL4. I had to install from c0d0p6 so partition could not be reformated during install.

After a (hardware) crash yesterday, I was unable to boot up due to unrecoverable ide errors (according to the printk()s) when accessing the root filesystem's journal for recovery. Unable to recover, I tried deleting the has_journal option, but that was disallowed given that the needs_recovery flag was set. I saw no way to unset that flag. Unable to access the backups (they were on a fw

Hi! I am studying HTB. I used the topology showed below: 10.1.0.1 ------ 10.1.14.25 (eth1) / 192.168.10.10 (eth0) ----- 192.168.10.11 (host 1) (router) (host 2) All machines use Debian Etch. Has a Iptables masquerading rule to eth1 in the router machine . The NICs are 100 Mb/s. The host 1 has Apache 2 and a file with 670 MB (CD ISO image) to download. When I used

Hi, I'm about to roll out a whole bunch of Redhat Enterprise 4 workstations and have run into problems cloning from the original. Normally I would use ghost (v7.5) because it does a nice job when cloning to a different sized disk.Unfortunately it comes up with read error 29004. Looking around it seems that Symantec don't support Fedora Core 3 (with Ghost v.8 - don't know if v.9 works

Is there a document anywhere offering guidance on the optimum use of ext3 filesystems? Googling shows nothing useful and the Linux ext3 FAQ is not very forthcoming. I'm particularly interested in: 1. The effect on performance of large numbers of (generally) small files One of my ext3 filesystems has 750K files on a 36GB disk, and backup with tar takes forever. Even 'find /fs -type

I have an ext3 filesystem that has several directories and each directory gets a large number of files inserted and then deleted over time. The filesystem is basically used as a temp store before files are processed. The issue is over time the directory scans get extremely slow even if the directories are empty. I have noticed the directories can range in size from 4k - 100M even when they are

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Searching in the ext3 filesystem mailing list I have seen that there is an indexed directory extension for it. Is this extension stable code ? Has anyone test it ? How may I obtain and install it ? Is it available in any of the last kernel releases ? Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34

That's definitely good advice, but even with e2fsprogs 1.35, if e2fsck -f is

Hi! I installed Debian in a pendrive and I used extlinux. I need a boot for multiples machines. When I use the config file below, my pendrive works fine: DEFAULT linux LABEL linux KERNEL ../vmlinuz APPEND ro root=/dev/sda1 initrd=../initrd But I need a boot for any machine. Then, I tried it: APPEND ro initrd=../initrd but the boot stops after discover the correct location of the root

Hi, I want to use an ext3 Partition (~1TB) for Mail Storage, this means tons of small files. Has anyone recommendations about blocksize, inodes, etc. for mkfs.ext3 ?

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.

Hi Guys, I am running ext3 on kernel v2.6.5. I have an ext3 filesystem with dir_index and data=journal for /var/spool/exim Today I noticed in the exim logs a bunch of 'failed to unlink /var/spool/exim/input/P/1BRbSP-0006hy-Jp-D' I also noticed these in the kernel logs: EXT3-fs warning (device hda12): ext3_unlink: Deleting nonexistent file (612870), 0 EXT3-fs warning (device hda12):
