[lustre-discuss] Installing lustre 2.15.6 server on rhel-8.10 fails

[Carlos Adean]

Hi Martin,

I really appreciate the help.

My answers are inline below.

One question: are you using the precompiled Lustre RPMs (e.g. those

Precompiled RPMs.

Your upgrade scenario is similar to ours. We’re upgrading our servers from
RHEL 7 with Lustre 2.12.6 to RHEL 8.10 with Lustre 2.15.x. The clients
previously ran RHEL 7 and will now run RHEL 9.5.

Our upgrade is described in a message posted on this mailing list on April

Actually, our Lustre environment is a bit complex. It has approximately
570 TB of capacity, organized into two tiers: T0 (70 TB) and T1 (500 TB).

Its infrastructure is composed of two MDS servers connected to a Dell
ME4024 storage array, and four OSS servers. Two of these OSS nodes are
equipped with NVMe SSDs and provide the T0 tier (high-performance scratch
space), while the other two OSS nodes are connected via SAS to two ME4084
storage arrays, supporting the T1 tier (long-term data). The entire system
operates with high availability (HA) and load balancing (LB) mechanisms.


Cheers,
