[LU-60] mkfs.lustre's --mgsnode=nid:nid syntax not working

Wed, 28 Feb 2018 20:06:30 +0000

Given the following node mapping:

192.168.122.147	oss1
192.168.122.160	oss2
192.168.122.89	mds1
192.168.122.115	mds2

When I format an OST with the following syntax:

oss1# mkfs.lustre --ost --reformat --mgsnode=mds1:mds2 --failnode=oss2 /dev/vda

and then try to mount it, the mount fails with dmesg reporting:

Lustre: 2876:0:(client.c:1476:ptlrpc_expire_one_request()) @@@ Request x1359778535178425 sent from MGC192.168.122.89@tcp to NID 192.168.122.115@tcp 5s ago has timed out (5s prior to deadline).

However if I format with the following syntax:

oss1# mkfs.lustre --ost --reformat --mgsnode=mds1 --mgsnode=mds2 --failnode=oss2 /dev/vda

mounting succeeds.

Just for good measure I tried a , instead of a : between the NIDs and the result is the same as for the :.
