Mounting BeeGFS v7 Storage on BeeGFS v8 Rocky Linux 9 Server for Data Migration

[John]

Hi all,

I'm migrating data from an existing live BeeGFS v7 setup (storage on 3 nodes, with one of them as the management server) to a new BeeGFS v8 cluster on Rocky Linux 9 standalone node with RoCE working.  I’d like to use the new parallel copy feature in BeeGFS 8, so my goal is to mount the v7 storage on the v8 server to copy data directly between clusters.

I’ve already installed BeeGFS 8 (client and storage) on the new storage. I attempted to install the BeeGFS v7 client in parallel using the bee-client-compat package as suggested in the docs, but the v7 client doesn’t seem to be buildable on Rocky 9—likely due to kernel/compiler compatibility issues.

Has anyone successfully mounted a BeeGFS v7 filesystem from a BeeGFS v8 client on Rocky 9, or is there an alternative method to perform this cross-version, cross-cluster migration-copy efficiently? 

Any guidance or examples would be much appreciated. Otherwise, is it a case of rsync the old fashioned way?

Thanks,

John
