Modify/etc/modprobe. conf and add the following content:

# Networking options, see/sys/module/lnet/parameters
Options lnet networks = TCP
# Alias lustre llite -- remove this line from existing modprobe. conf
# (The llite module has been renamed to lustre)
# End lustre modules

Installation is complete.

Lustre 1.6 adopts the new configuration method mountconf
Lustre 1.6 is configured through mkfs. lustre and mount. lconf, LMC, and XML are no longer used.

# Note that the following configurations of MGS, OST, and client are based on the same host
# Prepare the partition/dev/sdb1,/dev/sbd2 in advance

# Configure MDT/MGS

Mkfs. lustre -- fsname = testfs -- MDT -- MGS/dev/sdb1
