Hi all, (Sorry if this shows up twice - I got auto-unsubscribed and so first attempt was blocked) I'm keen to read up on some performance comparisons for replication versus EC on HDD+SSD based setups. So far the only recent thing I've found is Sage's Vault17 slides [1], which have a single slide

Re: [ceph-users] PGs in peered state?

I'm using the default (host level) crush map so that shouldn't be the case. Nothing was misplaced, etc. And yes, judging by the pg dump output these OSDs were on different hosts. I was thinking, maybe this has to do with OSDs not having a consistent state somehow? Or some pgmap issues? 6 сент.

[ceph-users] RBD: How many snapshots is too many?

Hi everyone, with the Luminous release out the door and the Labor Day weekend over, I hope I can kick off a discussion on another issue that has irked me a bit for quite a while. There doesn't seem to be a good documented answer to this: what are Ceph's real limits when it comes to RBD snapshots?

Re: [ceph-users] ceph OSD journal (with dmcrypt) replacement

Did the journal drive fail during operation? Or was it taken out during pre-failure. If it fully failed, then most likely you can't guarantee the consistency of the underlying osds. In this case, you just put the affected osds and add them back in as new osds. In the case of having good data on
