OK, so Ubuntu should be up to date. I created a virtual instance to try to reproduce it with a 20MB jfs filesystem, but no success so far. I could reproduce the root note corruption reported In another post, but that trashed only the /usr directory but did not lead to stale nfs locks so far. > > Jfs log extracted from system suffering problems after hard power down: > > This is with jfsutils-1.1.15, right? No ubuntu comes with ii jfsutils 1.1.12-2.1 utilities for managing the JFS filesystem > Also, do you see any errors in your syslog for the disks in question? No, everything seems normal, but I might search the logs again for any anomalies.
