Heya Greig, I had checked both our usual area for our d-cache logs (/var/log/d-cache) and where all the other logs are kept (/var/log), but neither seemed to have any full-bodied d-cache log files in them. There was however a strange symbolic link in /var/log/d-cache. I killed it and set the logArea variable in dCacheSetup was to /var/log/d-cache (also setting all printouts to 3), restarted everything, and my log files are filling up nicely. As to the pnfs dir permissions thing, I think I agree with the general consensus. The directory was created around midnight, things seemed a little busy, so whatever gremlin causes this feature cropped up. Thanks for the help and advice chaps, Matt
