Subject: [Ocfs2-devel] Why ocfs2 haven't implemented "steal" for local_alloc system files?
Date: Sat, 27 Jul 2013 18:27:29 +0800 [thread overview]
Message-ID: <51F3A091.4090605@huawei.com> (raw)
Hi,
While analyzing ocfs2 block allocation, I found:
When claiming space from inode_alloc (or extent_alloc) system files,
if there is no enough space in inode_alloc (or extent_alloc) and
global_bitmap, it could steal space from other slots.
But when claiming space from local_alloc system files, and no
enough space in local_alloc and global_bitmap, it returns -ENOSPC.
Why ocfs2 haven't implemented "steal" for local_alloc system files?
Is there any some reasons?
