Hi,
I've built and installed lustre on two VirtualBoxes running Rocky 8.8
and formatted one as the MGS/MDS and the other as OSS, following a
presentation from Oak Ridge National Laboratory: "Creating a Lustre Test
System from Source with Virtual Machines" (sorry, no link; it was a
while ago I downloaded them).
I can mount the filesystems on the MDS, but when I try from the OSS, it
just times out - from dmesg:
[root@oss1 log]# dmesg | grep -i lustre
[ 564.028680] Lustre: Lustre: Build Version: 2.15.58_42_ga54a206
[ 625.567672] LustreError: 15f-b: lustre-OST0000: cannot register this
server with the MGS: rc = -110. Is the MGS running?
[ 625.567767] LustreError:

[ 625.567851] LustreError: 1789:0:(tgt_mount.c:1752:server_put_super())

[ 625.567894] LustreError:

[ 625.588251] LustreError:
1789:0:(tgt_mount.c:2365:lustre_tgt_fill_super()) Unable to mount (-110)
Both 'nmap' and 'netstat -nap' show that there is nothing listening on
port 988:
[root@mds ~]# netstat -nap | grep -i listen
tcp 0 0 0.0.0.0:111 0.0.0.0:*
LISTEN 1/systemd
tcp 0 0 0.0.0.0:22 0.0.0.0:*
LISTEN 806/sshd
tcp6 0 0 :::111 :::*
LISTEN 1/systemd
tcp6 0 0 :::22 :::*
LISTEN 806/sshd
What should be listening on 988?
