I posted <https://github.com/ceph/ceph-build/pull/2282> to work around it
Pre-built Boost packages are just an optimization, their absence shouldn't be fatal (and it isn't for other PR checks)
We still need to determine why <https://chacra.ceph.com/r/libboost/master/55f34507d322314fb0294629b7c0bb406de07aec/ubuntu/jammy/flavors/default/> started throwing 403 Forbidden last week
@Dan Mick or @Adam Kraitman Any ideas?

<Adam Kraitman> @Ilya Dryomov Now it's reachable, a remount solved the issue

<Joseph Mundackal> <https://github.com/ceph/ceph/pull/59389> - what would the next steps be here... for this backport. Original reviewers and author has signed off on it

<Casey Bodley> thanks Joseph. that didn't make the 19.2.0 release, so it probably won't see any movement until we start testing for 19.2.1. in the meantime i added the core and needs-qa labels to make sure it gets picked up for the rados suite eventually

<ljon> Hi, I have question about rbd_diff_iterate2 function. When using this function, we can get diff blocks from say snap1 to snap2. I want to know in ceph object storage, does it commit the data block first then create the header of the data block? Consider the following: I want to write something to a rbd image. if I write a 4MB data block into a rbd image at offset 128. When 2MB is successfully written into the ceph object storage, the ceph is down. Once the Ceph is back online, I do a rbd_diff_iterate2, what block information do I get for the data I want to write at offset 128? Even more, if no data is written to offset 128, what block information do I get for that? Could you explain more about how does it work? when to create header and when to write data?
