-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 If I recall, there was a bug or two that was found with cache tiers and snapshots and were fixed. I hope it is being backported to Hammer. I don't know if this exactly fixes your issue. - ---------------- Robert LeBlanc PGP Fingerprint 79A2 9CA4 6CC4 45DD A904 C70E E654 3BB2 FA62 B9F1 On Mon, Sep 21, 2015 at 6:09 AM, Andrija Panic wrote: Hi, depending on cache mode etc - from what we have also experienced (using CloudStack) - CEPH snapshot functionality simply stops working in some cache configuration.
