        @manilx They get stuck for me on Delta Backups too (not just CR).

        Sometimes I have to do a Restart Toolstack to free it.

        Check for running tasks that are stuck. Or try a Restart Toolstack on the master (it normally does not hurt anything to do that just to try it).

          Hi,

          We added 2 fixes in latest commit on master, please restart your XAPI (to clear all tasks), and try again with your updated XO 🙂

              Can you try without any previous snapshot?

                @olivierlambert I reverted to previous version and backups OK.
                Then I updated again, deleted all snapshots (had to wait a while for garbage collection) and run fresh backups:

                1st full: backup progress bars not updating, staying at 0% (I can only check progress by seeing data written to the NAS). Backup finished OK using NBD.

                next delta: also run OK, without progress and all VM's showed ' cleanVm: incorrect backup size in metadata'

                So, some progress 😉 progress bars are really missing now 😞

                Speed still saturating the 2,5G management interface, so good.

                  @olivierlambert P.S. After delta backup I have all VM's with 'Unhealthy VDIs' waiting to coalesce but no Garbarge Collection job running.....

                  running cat /var/log/SMlog | grep -i coalesce on host gives:

                    @olivierlambert After 15min still nothing. No coalesce. Even after rescanning storage.

                    So still something broken.

                    Will revert as I need backups working reliably.......

                      @olivierlambert I had to reboot hosts to remove the Unhealthy VDIs.

                        @olivierlambert Each time I tried the new version(s) and I had trouble with coalesce stopping to work I have to reboot the hosts to get things going.

                        And I find the following in the log:

                        When there are entries with .cbtlog coalesce stops. These are created by the new NBD/CBT backups and somehow are left over....
