geo-rep: Rsync tunables for performance improvements
Flag: --ignore-missing-args
This Rsync flag reduces sync failures if the source file is
unlinked but present in --files-from list. This reduces
Rsync retries in Geo-rep and improves the performance
Flag: --existing
Rsync in Geo-rep never creates target files. Using RPC Geo-rep creates
entry in Slave and rsync --inplace used to prevent creating temporary file
and rename.(To avoid different GFID in Slave). If the entry is missing in
Slave then Geo-rep Rsync gets Permission denied errors when it tries to
create file with name as GFID inside .gfid dir.(Geo-rep rsync syncs data
using GFIDS with aux-gfid-mount)
To disable these flags,
gluster volume geo-replication <session> config \
rsync-opt-ignore-missing-args false
gluster volume geo-replication <session> config \
rsync-opt-existing false
Thanks Kotresh for finding these awesome tunables.
