Furure of ReiserfsV3?

Furure of ReiserfsV3?

[Christian Mayrhuber]

Hi,

if someone looks at the feature matrix of the major filesystems in 
kernel 2.6.0 it tells you the following:

FS        data ordered   EA   ACL   Quota   sec. labels   ext. journal
======================================================================
ext2             N       Y     Y      Y         Y            N
ext3             Y       Y     Y      Y         Y            Y
xfs              N       N     Y      Y         N            Y
jfs              N       N     Y      ?         N            Y
reiserfs         N       N     N      Y         N            Y
(reiserfs)       Y*      Y**   Y**    Y         N            Y

* data logging patches by Chris Mason (SuSE)
** EA/ACL patches by Jeff Mahoney (SuSE)

The current feature situation does not look great for reiserfs.
 From my point of view the latest data logging patches seem to behave 
very solid and are desireable to have in 2.6.x.
I have no experience with the EA/ACL patches from Jeff Mahoney, but
SuSE uses them for a long time.

What can be expected to be seen in reiserfs V3 before reiser4's big 
time? Or has reiserfs V3 entered a hard feature freeze.

We got bug reports for EA/ACLs.  I don't know what the status is of the 
fixes for them because we don't support them. SUSE does.

V3 is in feature freeze.  Use it, it won't break as a result of a new 
feature being added to it next month.  The data logging patches are 
probably the last significant change that will go into the vanilla 
kernel (and I would have preferred that they go in quite some time ago 
but.....)

New features are in V4.  It will be stable "real soon now". ;-)

SuSE is actively porting all of this.  Even though I've been saying this
for over a year now, it really is happening ;-)  Basically as we migrate
to 2.6 for our products, we'll be pulling in all the features we added
during the 2.4 kernels.

v3 has a lot of users, so we've no intention of leaving them behind in
the 2.6 series kernels.

Short summary of Hans and Chris Mason:

FS        data ordered   EA   ACL   Quota   sec. labels   ext. journal
======================================================================
reiserfs         Y       N     N      Y         N            Y
reiserfs_suse    Y       Y     Y      Y         N            Y

which is, IMHO, pretty good.
Great work developers!

Kernel 2.4:
Logging + Quota ftp://ftp.suse.com/pub/people/mason/patches/data-logging
EA/ACL for 2.4 http://acl.bestbits.at
EA/ACL for reiserfs ftp://ftp.suse.com/pub/people/jeffm/reiserfs/aclea

or use the SuSE/UnitedLinux Kernel

Re: Furure of ReiserfsV3?

Very interesting for your suggestion, does anyone got a benchmark to
compare XFS with reiserfs3 for large amount data process ? ( I am talking
about 20-30GB data pulling at once ) Thanks

XFS Will most likely win that benchmark.

I would not say that this is pretty good... I wonder why it isnot in
2.6. yet ?! Maybe it will make it for 2.6.x (x<5) ... ?
