Full Discussion: Empty directory, large size and performance
Operating Systems Linux Red Hat Empty directory, large size and performance Post 302591722 by verdepollo on Friday 20th of January 2012 11:30:40 AM

Well, that thread belongs to HP-UX and I wouldn't expect an inode to work the same on VxFS and Ext3/Ext4; things can be a lot different from platform to platform.

In RHEL, a file or a directory (which by strict linx definition is also a type of file) only uses a single inode, no matter what.

For a better overview of the real disk usage you can use "df" or "du".

clri

CLRI(8) 						    BSD System Manager's Manual 						   CLRI(8)

NAME

     clri -- clear an inode

SYNOPSIS

     clri special_device inode_number ...

DESCRIPTION

     Clri is obsoleted for normal file system repair work by fsck(8).

     Clri zeros out the inodes with the specified inode number(s) on the filesystem residing on the given special_device.  The fsck(8) utility is
     usually run after clri to reclaim the zero'ed inode(s) and the blocks previously claimed by those inode(s).  Both read and write permission
     are required on the specified special_device.

     The primary purpose of this routine is to remove a file which for some reason is not being properly handled by fsck(8).  Once removed, it is
     anticipated that fsck(8) will be able to clean up the resulting mess.

SEE ALSO

     fsck(8), fsdb(8), icheck(8), ncheck(8)

BUGS

     If the file is open, the work of clri will be lost when the inode is written back to disk from the inode cache.
