I am still having this weird problem with nodes hanging while I'm running OCFS. I'm using OCFS 1.0.9-12 and RHAS 2.1 I've been working on tracking it down and here's what I've got so far: 1. I create a file from node 0. This succeeds; I can /bin/cat the file, append, edit, or whatever. 2. From node 1, I do an operation that accesses the DirNode (e.g. /bin/ls) 3. Node 0

...there are any database files in that directory. The fix is to basically move all the files to a new directory then delete the old and rename the new. Step 2 sounds kinda weird, but it's actually the crucial step that will prevent the bug. Step 2 changes "file_lock" (in step 3) from OCFS_DLM_ENABLE_CACHE_LOCK to OCFS_DLM_NO_LOCK. 1. create a new directory. 2. create a file in the new directory and /bin/cat the file from a different node than the one where you created the directory. delete the file. 3. debugocfs -D /relative/path/to/newdir/from/mountpoint/ /dev/device -- confirm that "file_lock =...
