Here is a summary of the xrootd issues still open at GridKa:
(I was previously using the -d2 option but it looks like it doesn't exist
Writing fails (maybe a mistake I did in the config file):

2) DNS in recent releases
It still crashes but some tests from today morning seems to have solved
one server... we'll try tomorrow to make the same change on the others
and try to upgrade to the latest version.
3) Exporting multiple directories on GPFS
I have two servers (maybe only one in the future) and 3 directories to
export. I would be very happy if someone had an example on how to use mps
to export these.
This is not an issue but I just noticed that one of the NAS box is
actually not RH 7.3 but RH 8 so I am compiling myself there. No problem.
When all that is fixed, I'd like to learn how to use the monitoring in the
recent releases. Is it documented somewhere (I just found the CERN
presentation of Jacek)?
