Hello dear ceph users:
We are running a ceph cluster with Luminous (BlueStore). As you may know
this new ceph version has a new feature called "Checksums". I would like
to ask if this feature replace to deep-scrub. In our cluster, we run
deep-scrub ever month however the impact in the performance is high.
Source: ceph's documentation:
Checksums
BlueStore calculates, stores, and verifies checksums for all data and
metadata it stores. Any time data is read off of disk, a checksum is used
to verify the data is correct before it is exposed to any other part of the
system (or the user).
Sincerely,
Eddy Castillon
