Installing Buffer optimised code on Webdav aliased hosts

Currently the Webdav optmised code is build as a set of library files (rather than packages as an RPM), and updated xrootd cfg files.

Latest configuration

Current / testing

33dfdd3_2 ; latest version running on the gateways; no known issues (aside from the generally observed stability problems).

Library files

The necessary library files are:

libXrdCeph-5.so
libXrdCephPosix.so
libXrdCephPosix.so.0
libXrdCephPosix.so.0.0.1
libXrdCephXattr-5.so

And are put into their own directory, so not to overwrite the standard files.

Installation

Below COMMIT refers to a directory containing the required library files for XrdCeph. While it doesn't have to refer to the commit version, it's probably sensible that it does.

COMMIT=33dfdd3_2
cd ~/bufferCode/${COMMIT}
mkdir /usr/local/lib64/xrootd_buffer
chown xrootd:xrootd -R  /usr/local/lib64/xrootd_buffer
cd ..
cp -r ${COMMIT} /usr/local/lib64/xrootd_buffer/.


systemctl edit xrootd@proxy.service --full
# change line to this:   LimitNOFILE=655360

cd /etc/xrootd
# udpate the xrootd-proxy.cfg and xrootd-ceph.cfg files

systemctl daemon-reload
systemctl restart xrootd@proxy && systemctl restart xrootd@ceph

# noquattor the host

echo "WebDav Optimisations" > /etc/noquattor

xrootd-proxy

Example of the proxy config file; not there are host-specific lines

xrootd-ceph

Example of the ceph config file; note there might be host-specific lines
