Hi everyone,
This is potential flame bait, so I hope the worst doesn't happen. There
are a number of journalling filesystems out there for Linux, and among
them are XFS, ext3, and ReiserFS. In line with my evaluation of XFS, I'm
looking for documents that compare these three filesystems (or more
importantly, XFS vs ext3, and XFS vs ReiserFS).
I already know that for now ACLs only work with XFS (because the EA/ACL
project doesn't support ext3 yet, and ReiserFS is waiting until version 4
to start implementing ACLs). So that's one difference (with XFS winning
over the two other alternatives).
Does anyone have information on performance? Space utilization?
Reliability when recovering from unclean shutdowns?
In the area of reliability when recovering from unclean shutdowns I'm
particularly interested at how XFS deals with its cache/buffer. For
example in mail queues, with ext2 directories can be flagged using chattr
as +S so that all work done with these directories are synchronous. A
little slower, but this is much more stable especially for these queues.
With ReiserFS AFAIK mail queues currently run on a risk because perfectly
timed power downs could cause mail to "disappear". How would situations
like this be handled by XFS?
Again, thank you all in advance.
--> Jijo
