ReiserFS vs ext3 vs anything else?
As i'm sure you all know, ext2 (and then ext3) is the most widely used linux fs... but some distros (SUSE & Debian) are now chosing to either use by default, or at least give the option of using ReiserFS.
What is it about ReiserFS that's so great exactly? I understand that it has a limitless number of inodes, but surely there's more to it than this, right?
Also, just out of interest, are there any other fs types that other distros are using apart from ext[2,3] and reiserfs?

Hi,
My current linux server's filesystems is reiserfs. Unfortunately I need to enable quota for my users and as far as I know quota won't run on reiserfs.
So, can I convert the filesystem types to ext2 from reiserfs without having to re-install my o/s?
Or, is there any quota applications... (1 Reply)

resize_reiserfs
RESIZE_REISERFS(8) System Manager's Manual RESIZE_REISERFS(8)
NAME
resize_reiserfs - resizer tool for the ReiserFS filesystem
SYNOPSIS
resize_reiserfs [ -s [+|-]size[K|M|G] ] [ -j dev ] [ -fqv ] device
DESCRIPTION
The resize_reiserfs tool resizes an unmounted reiserfs file system. It enlarges or shrinks an reiserfs file system located on a device so
that it will have size bytes or size=old_size +(-) size bytes if the + or - prefix is used. If the -s option is not specified, the
filesystem will be resized to fill the given device. The size parameter may have one of the optional modifiers K, M, G, which means the
size parameter is given in kilo-, mega-, gigabytes respectively.
The resize_reiserfs program does not manipulate the size of the device. If you wish to enlarge a filesystem, you must make sure you expand
the underlying device first. This can be done using cfdisk(8) for partitions, by deleting the partition and recreating it with a larger
size (assuming there is free space after the partition in question). Make sure you re-create it with the same starting disk cylinder as
before! Otherwise, the resize operation will certainly not work, and you may lose your entire filesystem.
The resize_reiserfs program allows to grow a reiserfs on-line if there is a free space on block device.
If you wish to shrink a reiserfs partition, first use resize_reiserfs to shrink the file system. You may then use cfdisk(8) to shrink the
device. When shrinking the size of the device, make sure you do not make it smaller than the reduced size of the reiserfs filesystem.
OPTIONS
-s [+|-]size
Set the new size in bytes.
-j dev Set the journal device name.
-f Force, do not perform checks.
-q Do not print anything but error messages.
-v Turn on extra progress status messages (default).
RETURN VALUES
0 Resizing successful.
-1 Resizing not successful.
EXAMPLES
The following example shows how to test resize_reiserfs. Suppose 2Gb reiserfs filesystem is created on the device /dev/hda8 and is mounted
on /mnt. For shrinking the device we need to unmount it first, then run resize_reiserfs with a size parameter (in this case -1Gb):
df
umount /mnt
resize_reiserfs -s -1G /dev/hda8
mount /dev/hda8 /mnt
df /mnt
