[Ocfs2-users] Out of space with plenty of it

[Sergey Bolbat]

Thanks for help. I've tried to mount with localalloc=16 before but that
didn't solve the problem. Remounted with localalloc=4 and will monitor for
system's performance.

As for disk space error - I'm not recieving this error if the target
directory is local ext4 partition. That's why I assume that ocfs2 is the
reason. My application resizes images dynamicly creating new sized pictures
actually. However I receive out of space error not each time it tries to
create new image - only sometimes randomly.
