Create a new crush rule with the correct failure domain, test it properly and assign it to the pool(s). -- Beste Grüße, Joachim Kraftmayer ___________________________________ Clyso GmbH Am 05.05.2021 um 15:11 schrieb Andres Rojas Guerrero:

the crush rule with ID 1 distributes your EC chunks over the osds without considering the ceph host. As Robert already suspected.
Yes, the "nxtcloudAF" rule is not fault tolerant enough. Having the OSD as failure zone will lead to data loss or at least intermediate unavailability.
The situation is now that all copies (resp. EC chunks) for a PG are stored on OSDs of the same host. These PGs will be unavailable if the host is down.
