I'm no programmer but if I understand [1] correctly it's an unsigned long long:
int ImageCtx::snap_set(uint64_t in_snap_id) {
which means the max snap_id should be this: 2^64 = 18446744073709551616 Not sure if you can get your cluster to reach that limit, but I also don't know what would happen if you actually would reach it. I also might be misunderstanding so maybe someone with more knowledge can confirm oder correct me.

Hi,
There is a snap ID for each snapshot. How is this ID allocated, sequentially? Did some tests, it seems this ID is per pool, starting from 4 and always going up. Is that correct? What's the max of this ID? What's going to happen when ID reaches the max, going back to start from 4 again?
Thanks! Tony _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
