 Hi all,

 Function is_global_system_inode checks whether the type is
 in the range [OCFS2_FIRST_ONLINE_SYSTEM_INODE ,
 OCFS2_LAST_GLOBAL_SYSTEM_INODE ].
 But why the range does not include GLOBAL_INODE_ALLOC_SYSTEM_INODE ??

 enum {
   
    GLOBAL_INODE_ALLOC_SYSTEM_INODE,
     SLOT_MAP_SYSTEM_INODE,
 #define OCFS2_FIRST_ONLINE_SYSTEM_INODE SLOT_MAP_SYSTEM_INODE
     HEARTBEAT_SYSTEM_INODE,
     GLOBAL_BITMAP_SYSTEM_INODE,
     USER_QUOTA_SYSTEM_INODE,
     GROUP_QUOTA_SYSTEM_INODE,
 #define OCFS2_LAST_GLOBAL_SYSTEM_INODE GROUP_QUOTA_SYSTEM_INODE
     
 }

Hi Larry,
I think GLOBAL_INODE_ALLOC_SYSTEM_INODE system file is a reserved space 
for allocating inodes representing local allocater, etc.

So there is no chance for us to modify it since it has no relation with 
file space allocation and declaim.

So I suppose you are right, we won't use it anymore after mkfs until you 
have to tune it.

Thanks，
Changwei.

So it won't be used as an allocator after mkfs.ocfs2.  Is that true??

GLOBAL_INODE_ALLOC_SYSTEM_INODE is used for system files inode
allocation, you can refer to ocfs2-tools for details.

Thanks,
Joseph

[Ocfs2-devel] a puzzle about is_global_system_inode function

2017-10-24 Thread Larry Chen 
Hi all,

Function is_global_system_inode checks whether the type is
in the range [OCFS2_FIRST_ONLINE_SYSTEM_INODE , 
OCFS2_LAST_GLOBAL_SYSTEM_INODE ].
But why the range does not include GLOBAL_INODE_ALLOC_SYSTEM_INODE ??

enum {
   
    GLOBAL_INODE_ALLOC_SYSTEM_INODE,
     SLOT_MAP_SYSTEM_INODE,
#define OCFS2_FIRST_ONLINE_SYSTEM_INODE SLOT_MAP_SYSTEM_INODE
     HEARTBEAT_SYSTEM_INODE,
     GLOBAL_BITMAP_SYSTEM_INODE,
     USER_QUOTA_SYSTEM_INODE,
     GROUP_QUOTA_SYSTEM_INODE,
#define OCFS2_LAST_GLOBAL_SYSTEM_INODE GROUP_QUOTA_SYSTEM_INODE
     
}
