Excuse me if this has been covered already, though I did try to read through the archives. I am running md raid5 (software) over several drives and importing that into LVM and using reiserfs. It's worked fine for some time, but now I want to start snapshots. I've learned about the VFS lock patch, yes, but my real question is: why is the raid5 buffer cache constantly thrashing back and forth? I assume this has to do with a conflict between reiserfs's 4096 byte blocks and LVM's 512 SECTOR_SIZE. Or did I configure something wrong somewhere? Is it safe to just change SECTOR_SIZE in lvm.h or will that mess up on-disk structures? Thank you. -- chris jantzen kb7rnl =-> __O Insert witty comment here. _`\<,_ http://www.maybe.net/ (*)/ (*) _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
