Hi everybody,
I don't get why one of our compute node cannot start GPFS over IB.
I have the following error:
[I] VERBS RDMA starting with verbsRdmaCm=no verbsRdmaSend=no verbsRdmaUseMultiCqThreads=yes verbsRdmaUseCompVectors=yes
[I] VERBS RDMA library libibverbs.so (version >= 1.1) loaded and initialized.
[I] VERBS RDMA verbsRdmasPerNode reduced from 1000 to 514 to match (nsdMaxWorkerThreads 512 + (nspdThreadsPerQueue 2 * nspdQueues 1)).
[I] VERBS RDMA parse verbsPorts mlx4_0/1
[W] VERBS RDMA parse error verbsPort mlx4_0/1 ignored due to device mlx4_0 not found
[I] VERBS RDMA library libibverbs.so unloaded.
[E] VERBS RDMA failed to start, no valid verbsPorts defined.
I'm using Centos 7.3, Kernel 3.10.0-514.21.1.el7.x86_64.
I have 2 infinibands card, both have an IP and working well.
[root at rdx110 ~]# ibstat -l
mlx4_0
mlx4_1
[root at rdx110 ~]#
I tried configuration with both card, and no one work with GPFS.
I also tried with mlx4_0/1, but same problem.
Someone already have the issue ?
Kind Regards,
Frank
