DPM SRMv2 Tweaks

Got back from holiday to find that FDR transfers to Glasgow were failing with a "permission denied" error. Looking through the logs it seemed that the srmMkDir call was failing (unlike SRMv1 you need to make the path before transferring data into the SE).

However, it seems the default umask for DPM srmMkDir is 022, which leaves the directory unwritable. As I had tested the /dpm/ path I left it unwritable by Mario's certificate.

I fixed this with a dpns-chmod, but then I wrote a script to patch up the space token directory tree area using DPM ACLs to ensure the directories are group writable by the production role.

You can get the script here:
