[lustre-discuss] Using Ubuntu 24.04 as client

[Andreas Dilger]

You never need to reformat a Lustre filesystem when upgrading.

Cheers, Andreas

Peter,

Sorry about my way of putting t'he question, but I ment that when upgrading from 2.16.1 to  next LTS series (say 2.18.X, or whatever), no need to reformatting OSTs and recover data, right?

Best regards

I’m not 100% sure that I am understanding your question correctly here but, if you are asking “will 2.16.x be an LTS branch then the answer is that this is not the plan of record”. The 2025 OpenSFS survey will be out shortly and the results of that may result in more clarity around our plans in this regard…

Hi Peter,

Thanks for yor answer. I suppose, migrating for 2.16.1 to next LTS series is supported, right?

Best regards

There are no plans to backport Ubuntu 24.04 support for2.15.7 – we’ll still focus on Ubuntu 22.04 as our primary Ubuntu release for that. 2.16.1 was considered to be suitable for production usage with Ubuntu 24.04 clients at the time of its release so that could be an option for you, but please be aware that there will not be ongoing updates for that branch. The next LTS series would certainly focus on a newer Ubuntu version.

Regards

Peter

Hi all,

We are interested in upgrading our Lustre 2.15.X cluster to use Ubuntu 24.04 LTS as client and we see that Lustre 2.16.1 is supporting it.
Is that version stable enough to be in production or should we wait for the next LTS suporting Ubuntu 24.04 LTS?
Will Lustre 2.15.7 LTS be supporting Ubuntu 24.04 LTS or must we wait for the next LTS series?

Thanks in advance
Best regards
