Description Wendy Cheng 2007-02-20 15:20:12 EST
Description of problem:
While reading the directory, Linux NFS readdirplus procedure call also 
includes an optimization logic to build the file handles for all the 
files within that directory based on the directory contents at the same
time. Unfortunately, GFS2 passes NFSD on-disk ino address (no_addr - the
2nd 64 bit of GFS ino structure) to NFS in readdirplus but expects formal 
inode number (the 1st 64 bits) in lookup code when filehandle is actually 
used. This causes a large portion of NFS lookup failure when these file 
handles are actually used. A very significant issues when running NFS with 

Version-Release number of selected component (if applicable):

How reproducible:

Comment 2 Wendy Cheng 2007-02-27 16:13:41 EST
We'll tentatively set aside no_formal_ino and make lookup code consistent with
no_addr. Not sure whether we need a new bugzilla for not-NFS related changes ?
