It wasn't clear from your rail which message(s) are you concerned about? These
look like normal mount message(s) to me.
The "error" is pretty normal, it just means there were multiple services
starting at once and one wasn't yet ready for the other.
LustreError: 137-5: lustrevm-MDT0000_UUID: not available for connect
from 0@lo (no target). If you are running an HA pair check that the
target
is mounted on the other server.
It probably makes sense to quiet this message right at mount time to avoid this.

Hello Lustre community,
Have someone ever seen messages like these on in "/var/log/messages" on a
Lustre server ?

This happens on every boot on a Lustre server named vlfs (a AlmaLinux 8.9 VM
hosted on a VMware) playing the role of both MGS and OSS (it hosts an MDT two
OST using "virtual" disks). We chose LDISKFS and not ZFS. Note that this
happens at every boot, well before the clients (AlmaLinux 9.3 or 8.9 VMs)
connect and even when the clients are powered off. The network connecting the
clients and the server is a "virtual" 10GbE network (of course there is no
virtual IB). Also we had the same messages previously with Lustre 2.15.3 using
an AlmaLinux 8.8 server and AlmaLinux 8.8 / 9.2 clients (also using VMs). Note
also that we compile ourselves the Lustre RPMs from the sources from the git
repository. We also chose to use a patched kernel. Our build procedure for RPMs
seems to work well because our real cluster run fine on CentOS 7.9 with Lustre
2.12.9 and IB (MOFED) networking.
So has anyone seen these messages ?
Are they problematic ? If yes, how do we avoid them ?
We would like to make sure our small test system using VMs works well before we
upgrade our real cluster.
Thanks in advance !
