I've already moved the /home partition on my development box in the
apartment to ReiserFS from ext2. I'm running Linux kernel 2.2.16 patched
with ReiserFS 3.5.23. So far everything's doing great, and while it could
be a figment of my imagination, performance on files in /home seems to be
much better than before. No formal benchmarks were performed, though, so
this is non-conclusive. I plan to give myself some time then will
hopefully do some radical changes to our "production" server in the
office. We deal with a number of small files on a single 20GB EIDE hard
drive (I know, we're crazy and poor, bad combination), especially with
everyone's e-mails being stored in Maildirs. Together with this move I
will install a fresh installation of RedHat 6.2, and hopefully clean out
some stale files and applications still lying around from my wild
experimentations of installing from tarballs. I read about the possible
issue with QMail, though, so I will move the system to Postfix.
Would anyone know of the issues between ReiserFS and NFS? I saw an NFS
patch for SuSE boxes on the download page, but read nothing of an NFS
issue in the FAQ. I plan to retain the Maildirs, but will use Postfix as
the MTA (Maildrop as my MDA, with filtering capabilities). I hope this
will be okay. So far so good with my dev't box handling Maildirs.
The system will also be serving files via Samba. Anyone tried this?
Supposedly no issues, but just want to double check.
Budget-permitting I'll be granted funds for a second EIDE hard drive
(UltraATA/33) that I will set up as a mirror disk, using software RAID
level 1 for additional peace of mind. If this upgrade pushes through I'll
have both hard drives as masters on the first and second UltraATA/33 IDE
controllers respectively. I wonder how software RAID with ReiserFS will
perform on a setup like this. Will performance drastically drop,
theoretically? The box only has a single Celeron 400MHz CPU.
Hope some of you can share your views. I'll keep the list posted if and
when I upgrade this "production" Linux box to ReiserFS. In the meantime I
have to continue struggling with my 20 unit academic load. Argh! (I don't
know what the hell I'm doing playing with ReiserFS on my computer and
staying up until the whee hours of the morning, actually. And yes, the
timestamps are accurate, I sync my time with the US Naval Observatory's
timeservers regularly. Hahaha!!!)
