--=-RsWQwdMtceoboNcgqBCz Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi again, I also have a problem when I mount an exported filesystem through the carp VIP. When I do that: mount <real IP or alias>:/data/user /mnt while true; do time df -H /mnt > /dev/null; sleep 5; done 2>&1 | grep ^real real 0m0.004s real 0m0.004s real 0m0.004s real 0m0.004s real 0m0.004s ... But when I do that: mount <carp vip>:/data/user /mnt while true; do time df -H /mnt > /dev/null; sleep 5; done 2>&1 | grep ^real real 0m0.005s real 0m0.207s real 0m0.206s real 0m52.150s real 0m0.004s real 0m0.004s real 0m0.002s real 0m0.204s real 0m0.206s real 0m0.614s real 0m0.004s real 0m0.207s real 0m0.205s real 0m0.206s real 0m0.206s real 0m0.613s real 0m0.003s Every now and then I have a long delay with the vip that I don't have with the real IP or an alias...
