Hello, I am almost sure that unclean shutdowns happen in those systems. We have tried to reproduce removing power each 5 minutes and the filesystem wasn't suffering corruption. Perhaps it's related, but I don't know.
I have talked about 'Datalogging patches' because it's the only thing different from our system. I have searched a lot and few people have corruption with reiserfs standalone... so, it may be datalogging patches. what do you need from reiserfsck? I guess the output of 'reiserfsck --check device' of perhaps you need the output of reiserfsck --rebuild tree. Regards, Paco On Thursday, 13 de July de 2006 16:34, Vladimir V.
