Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


OK I upgraded both my blades to the latest stable kernel 2.6.24.
Rebuilt drbd 8.0.8 and restarted the sync.

I noticed off hand the connection to get sync was quicker than before

Apr  4 15:49:35 mailserv1 drbd0: conn( Connected -> WFBitMapS )
Apr  4 15:50:18 mailserv1 drbd0: conn( WFBitMapS -> SyncSource )

normally it used to take 5 or more minutes.

But as that was quick.. so was the "network failure" see below

I don't know if this will help, but this is the 'dmesg | grep eth0' output

eth0: Broadcom NetXtreme II BCM5708 1000Base-SX (B2) PCI-X 64-bit
133MHz found at mem dc000000, IRQ 17, node addr 00:1a:64:8c:91:e6
bnx2: eth0: using MSI
ADDRCONF(NETDEV_UP): eth0: link is not ready
bnx2: eth0 NIC SerDes Link is Up, 1000 Mbps full duplex
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present

I have "ping-timeout 20" and "rate 10M"  in my drbd.conf file.

Thanks
