e2fs unstable on powerdown

[David Zejda <dvid@atlas.cz>]

Hi!
I'm facing severe problems with e2fs on low-volume server with Postfix 
and NSD running. Every time the power goes off, the / is mounted ro 
(which is meaningful) and is a bit corrupted (10-20 files with 0 size, 
bad owners, completely lost etc.). I know, the best solution would be to 
buy the UPS, but is a such unstability common? I wouldn't be surprised 
in case of Raiser with cache enabled, but ext2 is known as a relative 
stable fs. Should I tune something or is the UPS the only way? Thanks 
for hints!

With regards
David
