Best inode_ratio for maildir++ on ext4
Hi,
This might be a silly question: which would be
the best inode ratio for a 5 Tb filesystem dedicated to Maildir++
storage? I use ubuntu server, which has a preconfigured setting for
mkfs.ext4 called "news" with inode_ratio = 4096, and after formating the
fs with that setting and then with the defautl setting I see this
difference of space (wasted space, but more inodes):

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

Faster mkfs.ext3
I'm currently working with a testing system that involves running
mkfs.ext3 on some pretty large devices on a regular basis. This is
getting fairly painful, and I was wondering if there was some way to
speed this up. Understood that the end result might be a filesystem
that has less of a safety factor (say, fewer superblock backups) but
the tradeoff might be worth it in this case.

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

Shrink ext3 filesystem , running out of inode questions
Hi,
I have an ext3 file system created with -T largefile4 option. Now it is
running out of inode but it's only about 10% full.
- Is there a way now to increase the number of inode without making a
new file system?
- If not, I am thinking about shrinking the file system, and then use
the free up space to create a new file system with more inodes, and move
the data over. Since I am

ext3 +2TB fs
I've got a 3.3TB ext3 on a FC3 64-bit system, running kernel
2.6.10-1.766FC3smp. I create the partition with parted 1.6.21, and I make
the fs via:
mkfs.ext3 -m1 -b 4096 -T largefile4 /dev/sda1
Works fine. bonnie++ running on it multiple times for days on end, no
problems.
However, I do the exact same setup on a RHEL4-AS i686 system, 32-bit, and

RFC: Tuning ext3
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

[PATCH] make-fs: Don't use du --apparent-size to estimate input size.
When calculating the initial size of the disk we must estimate
how much space is taken by the input. This is quite difficult.
For directories we used ‘du --apparent-size -bs DIR’. This is wrong
because ’-b’ implies ‘--apparent-size --block-size=1’. But also
‘--apparent-size’ causes du to count the file size rather than number
of blocks used by files.

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

[PATCH nbdkit v2 02/11] blocksize: Implement filtering of .can_multi_conn (forcing it to false).
I examined each filter to see which ones implement a cache and do not
properly consider consistency across clients for flush requests. For
these filters we should force .can_multi_conn to return false.
I believe only one filter (blocksize) needs to be updated and all the
other ones are safe.
