[GFS2] NFS fix - gfs2 filldir issue
Last modified: 2007-11-30 17:07:42 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):
Steps to Reproduce:
Patch submitted to cluster-devel and is currently under discussion.
Patch and discussion thread archived at:
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 ?
