Hello,
We'd like to configure AFS Fileserver using heartbeat in active/
passive mode.
The servers have been installed using the Big Box Linux ES46 (based on
RedHat) with OpenAFS 1.4.7, heartbeat 2.1.3 and DRBD 8.3.0.
The test layout consists of two servers and two partitions ( one is /
vicepa and the other is /usr/afs). The disk/partitons are visible
through the SAN on both servers and DRBD takes care about that.
On the heartbeat side we have the following haresource file
afsitfs3.roma1.infn.it IPaddr2::Y.Y.Y.Y/24/eth0:0
afsitfs3.roma1.infn.it drbddisk::r0 Filesystem::/dev/drbd1::/
vicepa::xfs
afsitfs3.roma1.infn.it drbddisk::r1 Filesystem::/dev/drbd2::/usr/
afs::ext3
afsitfs3.roma1.infn.it Y.Y.Y.Y afs
On the afs side we've also configured the NetInfo and the NetRestrict
file, in the NetInfo we put the IP address stored on VLDB server ( in
this case Y.Y.Y.Y) while in the NetRestrict put the IP addresses of
the two servers.
The problem is that everything is working fine inside the LAN but If
I try to execute a simple command like "ls" from outiside the LAN I got
Connection Timed Out
If we look at the FileLog file we saw that the Fileserver takes the IP
and hostname as the real server instead of the virtual one.
....
Mon Feb 2 13:18:37 2009 FileServer host name is 'afsitfs3.roma1.infn.it
Mon Feb 2 13:18:37 2009 FileServer afsitfs3.roma1.infn.it has address
141.108.26.29 (0x1d1a6c8d or 0x8d6c1a1d in host byte order)
.....
We really appreciate any suggestion for solving the problem
Thanks in advance
cristina
