* Make sure that Trond Myklebust's seekdir (or dir) kernel patch is

applied. The latest version (for 2.4.17) is located at:

  * IRIX servers do not always use the same fsid attribute field across

reboots, which results in inode number mismatch errors on a Linux client if the mounted IRIX server reboots. A patch is available from:

  * Linux kernels v2.4.9 and above have problems reading large directories

(hundreds of files) from exported IRIX XFS file systems that were made with naming version=1. The reason for the problem can be found at:

[http://www.geocrawler.com/archives/3/789/2001/9/100/6531172/] http:// www.geocrawler.com/archives/3/789/2001/9/100/6531172/

The naming version can be found by using (on the IRIX server):

xfs_growfs -n mount_point

The workaround is to export these file systems using the -32bitclients option in the /etc/exports file. The fix is to convert the file system to 'naming version=2'. Unfortunately the only way to do this is by a backup/ mkfs/restore.

mkfs_xfs on IRIX 6.5.14 (and above) creates naming version=2 XFS file systems by default. On IRIX 6.5.5 to 6.5.13, use:

mkfs_xfs -n version=2 device

Versions of IRIX prior to 6.5.5 do not support naming version=2 XFS file systems.

Irix versions up to 6.5.12 have problems mounting file systems exported from Linux boxes - the mount point "gets lost," e.g.,

        # mount linux:/disk1 /mnt                                            
        # cd /mnt/xyz/abc                                                    
        # pwd                                                                
        /xyz/abc
