Hi all,
Recently I encountered a situation requires reliable file storage with cephfs, and the
point is those data is not allowed to get modified or deleted.
After some learning I found that the WORM(write once read many) feature is exactly what I
need.Unfortunately, as far as I know, there is no worm
feature in cephfs.
So I was wondering is there any plan or design about this feature?
Thanks.
There's a pull request for this that has been stalled since spring:
https://github.com/ceph/ceph/pull/26691
Personally, I don't see how we can get away with making file data 100%
immutable. We'll need to allow _some_ entity to un-WORM the thing, and
it was never clear to me how that would work.
