Inode/Blocksize questions
Hi!
I'm going to build a maildir-based mailserver with a ~56 gb
mail-partition. What blocksize/bytes-per-inode/number of inodes should i
use (i don't want to ran out of inodes and don't want to sacrifice too
much space for filefragments)?
Is there a drawback when lowering the blocksize/increasing the number of
inodes (except the maximum filesystem size)?
The inodes used by a file is

dealing with mke2fs -T option
Hi,
I have a doubt if I use the mke2fs option the right way.
I formatted two different disks, one with
$ mke2fs -b 4096 -E stride=16 -m 1 -T news /dev/sdd
and the other with
$ mke2fs -b 4096 -E stride=16 -m 1 -T largefile4 /dev/sde
sdd is supposed to get files between 8k and 16k.
sde will handle files with a fixed size of 32Mb.
Then I tried this :
$ dd if=/dev/zero of=/mount-sdx/file bs=4k

Centos 5.1 ext3 filesystem limit
Centos 5.1 documentation states that the supported ext3 filesystem limit
is 16TB, yet I have a 9.5TB partition that is claimed to be too large:
mke2fs 1.39 (29-May-2006)
mke2fs: Filesystem too large. No more than 2**31-1 blocks
(8TB using a blocksize of 4k) are currently supported.
Am I missing something?

whoops, corrupted my filesystem
Hi all-
I corrupted my filesystem by not doing a RTFM first... I got an automated
email that the process monitoring the SMART data from my hard drive detected
a bad sector. Not thinking (or RTFMing), I did a fsck on my partition-
which is the main partition. Now it appears that I've ruined the
superblock.

About Names
Hello all,
I've been using ext3 since it was released for 2.2 kernel, and I've
always wondered about the name.
Calling it 'ext3' implies that it's a brand-new filesystem, not just a
journalling add-on for ext2. I guess I understand that you want to be
able to use ext3 and ext2 in the same kernel, but why not make it a
mount option, since the journal code is separate in the

another seriously corrupt ext3 -- pesky journal
Hi Ted and all,
I have a couple of questions near the end of this message, but first I have
to describe my problem in some detail.
The power failure on Thursday did something evil to my ext3 file system (box
running RH9+patches, ext3, /dev/md0, raid5 driver, 400GB f/s using 3x200GB
IDE drives and one hot-spare). The f/s got corrupt badly and the symptoms
are very similar to what Eddy described

Filesystem won't mount because of "unsupported optional features (80)"
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

[RFC] make extlinux work without mount the filesystem
Hello syslinux,
I'm a newbie to extlinux, and I'm a developer from yocto project
(an embedded linux project).
The device or filesystem must be mounted before we can install the
bootsector to the device if I understand correctly, for example:
$ mount /dev/sdcX /tmp/mnt
$ extlinux -i /tmp/mnt
Usually, the mount command requires the root privilage, we may not
have the root privilage when

[PATCH node] split root filesystems out of HostVG and onto their own partitions
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.

How to create a huge file system - 3-4TB?
We have a server with about 6x750Gb SATA drives setup on a hardware RAID
controller. We created hardware RAID 5 on these 6x750GB HDDs. The effective
size after RAID 5 implementation is 3.4TB. This server we want to use it as
a data backup server.
Here is the problem we are stuck with, when we use fdisk -l, we can see the
drive specs and its size as 3.4TB. But when we want to create two different

large_file feature- where is it?
I recently ran into an issue where I couldn't create a file larger than
2GB on a particular ext3 filesystem. I was under the (mistaken)
impression that >2GB support went in before ext3 support, and all ext3
filesystems would therefore support >2GB files on ia32.
So, I started poking around and found that some of my ext3 filesystems
have the "large_file" feature flag set on

Question About Relocating Journal on Other Device
Hi. I'm using e2fsprogs 1.23 on a Roswell system with a patched 2.4.7
kernel (using patch ext3-2.4-0.9.5-247) and am trying to create an ext3
filesystem whose journal is located on another device. The incantation I'm
trying is:
mke2fs -j -J device=/dev/hdc2 /dev/hdc3
I keep getting an error along the lines of "mke2fs: Journal superblock not
found". I've tried creating
