Any ideas as to why some > nodes could see the VIP and others couldn't? GARP is not a reliable protocol. By itself, it does not retry. Have a look at the keepalived.conf documentation. There are several settings which enable the master periodically re-sending the GARP packets. For me, that solved the issue once and forever. The settings go into each vrrp_instance section you use. I run with: garp_master_refresh 5 garp_master_refresh_repeat 1 These settings send one (repeat setting) GARP every 5 (the other setting) seconds. best regards Patrick ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot
