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

[Srinivas Eeda]

then your application shouldn't get enospc error. I would suggest you to 
look into your application for why it reports "out of disk space" error.

As for poor write speed, I guess your file system might be fragmented 
heavily. Umount and remount your file system with mount option "-o 
localalloc=4" If 4 didn't help then go down to 2 and see if that helps.

Thanks,
