Hi,
I'm running into some issues when trying to set up a new IB cluster.
I've got machine A which has connections to machine B and C via a
single two-port ConnectX card. A and B are connected and have no
known problems. I just set up machine C (installed OFED-1.5.1) but
whenever I run ibv_devinfo I get:
libibverbs: Warning: couldn't load driver 'mlx4':
/usr/local/lib/libmlx4-rdmav2.so: symbol ibv_cmd_get_eth_l2_addr,
version IBVERBS_1.0 not defined in file libibverbs.so.1 with link
time reference
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs2
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs1
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0
No IB devices found
The machine does have 3 HCAs. For reference OFED 1.5.1 has
deposited the following RPMs on the system:
libmlx4-1.0-0.7.g2432360
libmlx4-devel-1.0-0.7.g2432360
libibverbs-1.1.3-0.6.g932f1a2
libibverbs-devel-1.1.3-0.6.g932f1a2
libibverbs-devel-static-1.1.3-0.6.g932f1a2
So you only have some installation problem on machine C. By default, OFED
installation script will install to /usr and I see that in C the
prefix is /usr/local - is this what you intended? I think you may have
old libraries in the library path so you may need to remve them.
Ah, that's probably it. I did install my own libmlx4. I guess I
thought it went to the same place that the OFED installer put things, so
when it said it was uninstalling previous version of OFED it would get
rid of that too. I'll clean it out more thoroughly and try again.
Thanks.
