[lustre-discuss] Question About Mellanox-RDMA On Lustre

[Brad Merchant]

It looks like your mkfs commands are not quite complete. The "failnode"
option is deprecated and specifying only one will make that target only use
that IP address. So it's timing out because it doesn't have an LNET address
available to contact the MGS. It would likely work if you tried to mount
from the other server.

Assuming some topology here so it might not be completely accurate, but I
think the mkfs commands you want are:


mkfs.lustre --fsname=ltfs1 --mgs --mdt --index=0
--servicenode=192.168.19.14 at o2ib1 --servicenode=192.168.19.15 at o2ib1
 --reformat --mkfsoptions "-E stride=32"
/dev/disk/by-id/scsi-3600b3420371420b645dde4066c0000a8
