As the title suggests...I've taken a snapshot of a running KVM machine (including RAM) on my Ceph cluster. It worked, but now I'd like to know how much space it's taking on ceph cluster and if this space will remain the same forever or will grow in the future. Thank you very much!
How much space does a KVM snapshot on Ceph take?
- Thread starter lucaferr
- Start date
when you take a snapshot, it take 0 space at the moment of the snapshot.
Then, when you write new datas on an existing block, the space of the snapshot increase.
(So, the maximum size of the snapshot could be the size of the disk if you rewrite all blocks)
