Hello, all:

I may be being stupid here, but:

I'm in the initial phase of messing around with xrootd here at
Glasgow, and I can't seem to get my diskserver to add itself as
writeable.

The arrangement is:
svr025.gla.scotgrid.ac.uk running as a redirection server (xrootd on
port 2525 and olbd on 2526)
disk042.gla.scotgrid.ac.uk (for example) running as a data server
(same services on same ports)

The config for the two is:

redirector:
#
# redirectserver.cf
#
# xrootd
xrootd.port 2525
xrootd.fslib /root/20090202-1402/lib/libXrdOfs.so
xrootd.export /gridstore4
#oss.readonly
odc.manager svr025.gla.scotgrid.ac.uk 2526
odc.trace redirect
# olbd
olb.port 2526
olb.allow host disk042.gla.scotgrid.ac.uk
olb.allow host svr025.gla.scotgrid.ac.uk
ofs.redirect remote svr025.gla.scotgrid.ac.uk
xrootd.allow host svr025.gla.scotgrid.ac.uk


dataserver:
#
# dataserver.cf
#
# xrootd
xrootd.port 2525
xrootd.fslib /root/20090202-1402/lib/libXrdOfs.so
xrootd.export /gridstore4
#oss.readonly
odc.manager svr025.gla.scotgrid.ac.uk 2526
# olbd
olb.port 2526
olb.subscribe svr025.gla.scotgrid.ac.uk 2526
ofs.redirect remote svr025.gla.scotgrid.ac.uk
oft.redirect target


However, when disk042 connects to the redirection server, I see:

090506 14:19:21 31690 olb_Manager: server disk042 defaulted r /

and on the disk:
090506 14:18:01 001 olb_Meter: Warning! No writable filesystems found;
write access and staging prohibited.

and, indeed, xrdcp to disk042 fails (but copying from it works perfectly).
The exported filesystem (/gridstore4) is writable by the user owning
the xrootd processes, however (indeed, it is owned by the same user,
with mode 770).

This is probably something stupid, but... any help appreciated.
