    Buenas,

     

    Lo he intentado con dos servidores placas Supermicro raid 1 de dos discos, todo el hardware identico, sin exito. Se queda realizando el cluster y termina fallando. ¿Alguien lo ha conseguido?

    I replicate your scenario, with the 2 super micro boards , raid 1 in both servers, and both with different macs on eth0 and eth1, serial different too, but unfornately no luck.

     

    Please any help would be greatly appreciated.

     

    Thanks

    Hi all,

     

    I´m trying to do the same setup with HA on 2 Supermicro boards Atom onboard, same hardware on both servers. Did you get it to work finally?

     

    Please share your results.

     

    Did the Mac address change and vendor solve the problem?

     

    Thanks in advance.

     

    Regards.

     

     

     

    I had a play with this today

     

    for testing

    2 x Supermicro 1RU servers

    20g ram

    2 x 250g drives in each, setup as a mirror (High Availability doesnt allow SHR)

    2 x Intel Lan ports

     

    setup 1st one with 4.3 3810 v1.0 from trantor

    once installed, I broke the SHR config and rebuilt as a mirror set RAID1

     

    setup local time properly

    added a user

    made sure networking was setup properly

     

    edited grub.conf to reflect the propery mac address's in each server and both had different serial numbers

     

    Set static IP's

     

    Server 1

    lan port 1 = 10.0.0.52, 255.255.255.0 <

    lan port 2 = 192.168.0.1 255.255.255.0 <<< which doesn't matter as HA software changes this later too 169.254.1.1 255.255.255.252

     

    Server 2

    lan port 1 = 10.0.0.53, 255.255.255.0 <

    lan port 2 = 192.168.0.2 255.255.255.0 <<< which doesn't matter as HA software changes this later too 169.254.1.1 255.255.255.252

     

    Connected a cable direct from Server 1 to Server 2 both on Lan port 2

     

    Double checked that all ports were running @ 1000Mbps......as 2 were not 1st off.....swap some cables around until all 4 ports were up @ Gigabit

     

    Then off to install HA package (which 1st need you to install the python package)

     

    Tested the setup, but yes it fails at the end

     

    Then I thought, as each server has two ip addresses on Lan port 1.....eg one that you setup, then I guess a virtual / bridged one that you type in in the setup.... it must need bridging enabled??

     

    had a looksee and it seems the bridge module isn't loaded...

     

    /lib/module/bridge.ko

     

    is there

     

    so lets load it

     

    insmod /lib/module/bridge.ko

     

    fails as it need also /lib/module/stp.ko and /lib/module/llc.ko

     

    now with all three loaded lets try again......

     

    now it fails with

     

    Jan 1 23:03:50 SUPER1 ha.cgi: write to uart2 error, error=(5)Input/output error

    Jan 1 23:03:50 SUPER1 ha.cgi: ha.cc:1712: SYNOHWExternalControl failed 8192

     

    which I wonder is something to do with the serial port?

     

    which I will enable next.... tho I wonder if the REAL hardware has something attached to a serial port inside it?
