Hi,
I have one server for MGS/MDS function and 4 server for OSS. All
machines are identical. MDS is connected to back and storage that is
serving two data LUN's. OSS's are connected to back end storage that
is serving 24 data LUN's. each server has two network interface
configured as follows.
OSS1(hostname=storage07) [EMAIL PROTECTED]
OSS1(hostname=storage07) [EMAIL PROTECTED]
OSS1(hostname=storage08) [EMAIL PROTECTED]
OSS1(hostname=storage08) [EMAIL PROTECTED]
OSS1(hostname=storage09) [EMAIL PROTECTED]
OSS1(hostname=storage09) [EMAIL PROTECTED]
OSS1(hostname=storage10) [EMAIL PROTECTED]
OSS1(hostname=storage10) [EMAIL PROTECTED]
MDS1(hostname=mds01) [EMAIL PROTECTED]
MDS1(hostname=mds01) [EMAIL PROTECTED]
MDS2(hostname=mds02) [EMAIL PROTECTED]
MDS2(hostname=mds02) [EMAIL PROTECTED]
tcp0 is 10GbE
tcp1 is 1GbE
I would like to configure lustre in such a way that if tcp0 interface
will fail on the OSS or MDS, lustre will be able to use secondary
network to keep communication alive and at least some of the clients
could. Primary network should be 10GbE and secondary network 1GbE
I have prepared following makefs.lustre lines:

Will this work as I suppose?
