Hi Peter, For the EL 10.1 client I was using version 17.0 which was the only version to support EL 10. After upgrading to EL 10.2 the client lost the storage mount. I'm not updating the EL9.7 clients, not to risk losing the storage mount. They are running the 2.15 LTS Lustre. On the servers I am still using the 2.15 version on EL 8.10 as I prefer to use the LTS version, and there is no LTS server support beyond EL 8.10. This complex matrix just emphasizes how much Lustre is a restrictive factor for upgrades.
