If the interface/link configured for MR with LNet is brought down then up, it causes corresponding routes created by 'setup-mrrouting' script to disappear. For example: # ip route show table ens12 192.168.122.0/24 dev ens12 proto kernel scope link src 192.168.122.134 # ip link set ens12 down # ip link set ens12 up # ip route show table ens12 # Same effect is observed if "ifdown/ifup" commands are used. The routes are added back only upon LNet module reload. It is better to make these routes persist in this case as most of users are likely to expect. |
