A saved dmesg from the time shows: [ 66.271468] OCFS2 Node Manager 1.3.3 [ 66.281869] OCFS2 DLM 1.3.3 [ 66.288291] OCFS2 DLMFS 1.3.3 [ 76.221164] OCFS2 1.3.3 However, this numbering doesn't seem to be the one used for the project per se. > I found a site (I don't have the URL handy at the > moment) dated over a year ago that did some stress testing with gfs, > ocfs2 and I think one or two others, and they noted that gfs was the > only one that didn't give any trouble in the testing.
