I would have high-availability if I have a bonding mode 0,1 or 2. But I have
LACP bonding attached to the same switch, if I loose a switch, my OSS will be
down.

Then follow the instructions in my earlier mail.
No need to have bond0 and bond1.
You will achieve high-availability even with one bonded interface.

Yes I have two swtiches, one to the bond0 interface and other switch to the
second bond1 interface.

Hi Alf
The virtual inferface will be the OSS. A virtual IP will start in the first
interface, and if the network attached to the first interface is failed, the
virtual IP is move to the second interface.
I need have two networks, because I need to guarantee to my clients a network
in HA and minimized
Can you describe the failure in more detail?

I am not aware of any tool or method to recover from a lost MGT/MDT. Do
you have any recent backups of your MDT device?
I would hold on to your MDT device with care and see if someone can help
you resurrect it.

All,
We have a sizeable filesystem and during a hardware upgrade, our MDT disk was
completely lost.
I am trying to find if and how to recover from such an event, but am not
finding anything.
We were running lustre 2.3 and have upgraded to 2.4 (or are in the process of
it).
Can anyone point me
Hi Alfonso,
I guess, you have two switches, with 2 interfaces (bond0) connected to one
switch and the other 2 interfaces (bond1) to the second switch.

What you need to do is merge the switches using a 'stacking' cable (if the
switches are stackable) and create a single trunk using 2 ports fr
That will probably be slow - the machine you use to proxy the IPVS address
would be a bottleneck. Out of curiosity, what problem are you trying to
solve here? Do you anticipate whole-subnet outages to be an issue (and if
so, why)?

oooh!
Thanks for you reply! May be another way is a floating IP between two
interfaces with IPVS (corosync).
