Обсуждение: Anyone using ReiserFS in production work? (or advise against it?)

The title says it all: Is this a foolhardy or prudent and wise move at this time?

Has anyone run Postgres databases on ReiserFS volumes under heavy enough load and for long enough to get a sense of how
stableit is?  

Anyone tried pulling the power plug under heavy load to find out if ReiserFS is less prone to volume corruption than
ext2under these circumstances?

I myself have NO experience with it, but I read somewhere that
sourceforge is running with it as we speak :-)  They are a big Open
Source (tm) repository wth CVS and other access, so it is presumably
pretty robust.

Not very heavy load, but for long enough time.

Less. I never had "bad" corruption with reiser. On other hand, I never had
'bad' corruption with ext2 either. ;) But theoretically, its possible with
ext2 and avoidable with reiser.

Well, not in production yet, but on my machine running a copy of our
message switch on a reiser partition. I currently have a "stuck on
TLB" (if I remember the error correctly) but this is not reiser
specific (and a patch exists which I have to try when I get time).

Hmm, pulling plug, no, but the machine has hung up 2 or 3 times while
trying out pre versions of 2.2 Linux and has come up without any
problems.

We have just ordered 2 new servers and I am going to put reiserfs and
RAID through its paces, try pulling a disk while running, pulling the
power, etc. to get a good idea of what can go wrong and whats needed
to fix it.

I suggest you try something similar before going to production.

Sincerely,

Adrian Phillips
