Ceph stretch pools in squid

[Gilou]

Hi,

Has anyone experimented with ceph stretch pools that seem to have appeared in squid? (not stretched clusters)

It seems rather new, but rather interesting, as it may not require the whole cluster to be set to stretched, while still dealing with the guarantee of OSDs and monitors being on the same side, and duplication of the data on both sides… However, documentation is scarce on that subject, so I plan on investigating a bit, but if if anyone already has... I'd be happy to read about it!

ah, just read @ https://docs.ceph.com/en/latest/rados/operations/stretch-mode/#individual-stretch-pools that netsplit cause IO block with individual stretch pool, so, not exactly the good usecase..
