RHEL5.2/Centos5 kernel update may cause problems

Posted by chris Mon, 21 Apr 2008 16:20:25 GMT

This is a heads up for RedHat Enterprise Linux (RHEL) users as well as for users (like myself) of the various Centos variants.

There is a recent patch for RHEL that changes the inode data structure exposed to NFS clients from 32 bits to 64 bits in size. The basic summary of this issue is that many applications may not handle this change gracefully (such as one report with the SGE linux binaries.)

RHEL and modern Centos users should probably pay attention to (by subscribing as CC: contacts) to this issue:

A RedHat bug report discussing the issue in more detail is here:
