Hello,
I am in a situation in which I have a bunch of lustre clients which may
access two different lustre
infrastructures. One is working on TCP and the other on infiniband.
So I have 2 OSS groups. One group is reachable thought TCP/Ethernet and
the other group through infiniband.
The problem is that I am not able to have both of them working client side.
Clients can mount both OSS groups via TCPnd
options lnet networks=tcp(ens1d1),o2ib(ib0)
but I'd want to be able to use infiniband for the OSS which has
infiniband interface.
So if I set infiniband as first option
options lnet networks=o2ib(ib0),tcp(ens1d1)
only the OSTs related to infiniband OSSs are mounted while the OSTs
belonging to OSSs
reachable through Infiniband are not available.
I am not able to deploy a configuration which would allow me to do both
things at the same time.
I Tried also to do this:
options lnet 'ip2nets="o2ib0(ib0) 172.21.49.[224-229]"' 'routes="o2ib0
172.21.49.[224-229]@o2ib0"'
where 172.21.49.[224-229] are my o21b network IDs (IPoIB) regarding the
OSSs in the infiniband group.
but this still cannot fix.
What do I need to do to have my clients to be able to mount one group of
OSS through TCP and
the other group of OSS through infiniband ?
thank you
Riccardo
