Hi Postfix-Users!
I know, there is enough written on the net and on the mailinglist too, but
have found only old results, maybe the meanwhile something is different,
also I would ask you...
Which filesystem do you use on your mailserver?
I'm going to migrate a mailserver with EXT3 (and qmail) to a new postfix
mailserver (virtual domains on mysql, ...).
I would create the system on EXT3 (RHES) and the following partitions on
rieserfs:
I would never use reiserfs for anything except our disposable Squid
Cache. Stay with ext3, it works.
But ext3 does have problems -
All our production boxes are 100% reiserfs, and have been for some
years, based on performance testing. They have been rock solid, and most
of them have 800 day uptimes at this point. I did some performance
comparisons a few months ago and reiser still has a large lead over
ext3. As reiser has always been the default filesystem on suse
enterprise linux, it stands to reason that it has been well vetted.
Of course, the legal woes of the reiserfs creator have put the future of
the filesystem in doubt. The future seems to be btrfs. ext4 might be a
good stepping stone along the way, when it's ready, but if I had to pick
a filesystem to deploy today, it would be reiserfs - xfs could get some
consideration as well, but we just really don't want the performance hit
that comes with ext3.

But it also is one of the most used and tested file systems for Linux.
We also used reiserfs under Suse and had so many problems with it in an
iscsi SAN environment. I can remember 2-3 full 6 hour recoveries had to
be done with lost data as the prize in the end and this for the
mailserver only. We had several servers with fs corruption to the point
I preached against using reiserfs and they finally listened. Switched to
ext3, on all servers which I wanted to do for years, and haven't had an
issue yet except one fsck that was performed and it did not loose data.
Even if you want the fastest filesystem for your needs, what is the true
bandwidth you are seeing currently? What is your iowait? I bet it isn't
really isn't that much overall where reiserfs vs ext3 vs whatever will
make a huge improvement.
Thanks,
