Hi all,
We're looking at using Ceph's copy-on-write for a ton of users'
replicated cloud image environments,
and are wondering how efficient Ceph is for adding user data to base
images -
is data added in normal 4kB or 64kB sizes, or can you specify block size
for volumes
(so you can have video partitions with large content and email/chat/web
cache partitions with small files)
Is Ceph's behavior & configuration for copy-on-write documented well
somewhere?
Thanks.
