Re: upgrade jewel to luminous with ec + cache pool

Yes, migrating to 12.2.8 is fine. Migrating to not use the cache tier is as simple as changing the ec pool mode to allow EC over writes, changing the cache tier mode to forward, flushing the tier, and removing it. Basically once you have EC over writes just follow the steps in the docs for removing a cache tier.

Dear all,

i am running a cephfs cluster (jewel 10.2.10) with a ec + cache pool. There is a thread in the ML that states skipping 10.2.11 and going to 11.2.8 is possible, does this work with ec + cache pool aswell ?

I also wanted to ask if there is a recommended migration path from cephfs with ec + cache pool to cephfs with ec pool only ? Creating a second cephfs and moving the files would come to my mind, but maybe there is a smarter way ?

Cheers,
Markus
