Description Wendy Cheng 2007-02-20 15:26:26 UTC
Description of problem: Glock assertion failure found in '07 NFS connectathon. One of the NFSDs was doing a "readdirplus" procedure call. It passed the logic into gfs2_readdir where the call obtained its directory inode glock. It then subsequently tried to construct the filehandle based on the contents of the directory lising that invoked lookup and comes down to gfs2_drevalidate(). It hit the assertion failure while trying obtain the inode glock again. Version-Release number of selected component (if applicable): All How reproducible: Each time and every time Steps to Reproduce: * Run cthon04 test suite Actual results: System panic Expected results: No panic Additional info: Patch had submitted to cluster-devel and has been in Linux tree since sometime after Feb. 12.

Comment 7 Mike Gahagan 2007-09-12 20:10:11 UTC
Confirmed the fix is in, and I hit what looked like this panic with the GA kernel just by having a nfs exported gfs2 mounted using nfsv3 and trying to do an ls of the directory. nfs3 mounts when the system hosting the gfs2 fs is running the -45 kernel seems to work fine.
