Hi list, we have a ceph cluster running ubuntu 22.04 and quincy packages from ubuntu. To keep up with the releases of Ceph, we want to upgrade to a more recent stable release... We could upgrade to ubuntu 24.04 LTS (re-install actually) but the ceph version then skips 18.2.x and goes directly to 19.2.x, if this is a supported upgrade, that would be the least amount of work, since upgrade of the OS will be needed at some point anyway. We are not planning a move to cephadm yet. I suppose if we need to install 18 before 19, we'd need to add the ceph repo for ubuntu package to upgrade and then upgrade to ubuntu 24.04's ceph 19.2.x after reinstalling all the ceph servers... Has anyone successfully upgraded from 17.2.x to 19.2.x in one upgrade step? (And is this supported?) Cheers /Simon -- I'm using my gmail.com address, because the gmail.com dmarc policy is "none", some mail servers will reject this (microsoft?) others will instead allow this when I send mail to a mailling list which has not yet been configured to send mail "on behalf of" the sender, but rather do a kind of "forward". The latter situation causes dkim/dmarc failures and the dmarc policy will be applied. see https://wiki.list.org/DEV/DMARC for more details
