Lost packets and dead/warntime

[Sebastian Vieira]

Hi again,


I've disabled the onboard NIC on both nodes and placed 2 new NICs: one 3Com
2000T and another Intel Gigabit card. So far (+/- one hour running) there's
not a single lost packet, which makes me very happy. The cards still run on
100Mbit but that'll change later this week. I don't think this will matter
much but since the cards support it, why not use it?

Anyway, thanks for the suggestions. I'll let it run for another week and if
the failover goes smooth too, i'll put it into production env.

Hmm .. as i'm composing this mail, i just noticed some lost packets on the
inactive (backup) node with the 3com card. I've set the keepalive value
(heartbeat) to 100ms. This is for Remote Desktop connections (Windows
Terminal Services). I don't suppose anyone has a similar setup and would
like to tell me what their value is?

kind regards,

Sebastian
