Good Afternoon,
While getting lustre 2.10.8 running on a RHEL 7.7 system I found that the
RPM install was putting a file in /etc/modprobe.d that was preventing lnet from
starting properly.
the file is ko2iblnd.conf, which contains the following...
alias ko2iblnd-opa ko2iblnd
options ko2iblnd-opa peer_credits=128 peer_credits_hiw=64 credits=1024
concurrent_sends=256 ntx=2048 map_on_demand=32 fmr_pool_size=2048
fmr_flush_trigger=512 fmr_cache=1 conns_per_peer=4
install ko2iblnd /usr/sbin/ko2iblnd-probe
Our system is running infiniband, not omnipath. So I'm mot sure why this file
is being put in place. Removing the file allows lnet to start properly.
w/r,
