Harald has merged the rd.route option of semicolon as separator. This v4 post corresponds to that. On 07/30/14 at 02:05pm, Baoquan He wrote:

If one target address is not local and its route is different than default gateway, the specific route to this target address need be added. E.g, target is 192.168.200.222. sh> ip route show default via 192.168.122.1 dev eth0 proto static metric 1024 192.168.200.0/24 via 192.168.100.222 dev ens10 proto static metric 1 In this patch, get the route to the specific target address and store it as cmdline, here is /etc/cmdline.d/45-route-static.conf. And the route options are separated by semicolon like below. Then the stored route can be parsed when kdump kernel boot up. 192.168.200.0/24:192.168.100.222:ens10 Signed-off-by: Baoquan He <bhe(a)redhat.com&gt; --- dracut-module-setup.sh | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/dracut-module-setup.sh b/dracut-module-setup.sh index 5ab2997..fefbe4b 100755 --- a/dracut-module-setup.sh +++ b/dracut-module-setup.sh @@ -79,6 +79,11 @@ kdump_static_ip() { _gateway=$(ip route list dev $_netdev | awk '/^default /{print $3}') echo -n "${_srcaddr}::${_gateway}:${_netmask}::" fi + + /sbin/ip route show | grep -v default | grep "^[[:digit:]].*via.* $_netdev " |\ + while read line; do + echo $line | awk '{printf("rd.route=%s:%s:%s\n", $1, $3, $5)}' + done >> ${initdir}/etc/cmdline.d/45route-static.conf } kdump_get_mac_addr() { -- 1.8.5.3
