      @florent I did a git update again (to commit aa261) and it works! Maybe I missed and update?,,,,

        @Andrew the problem occurs only during resuming a merge

        Does your S3 provider apply some rate limits to queries ? We do a lot of copy / delete query during merge

          @florent For local testing I'm using MinIO and there is no limit or throttling enabled.

            @Andrew I am testing on another user with less concurrency during merge ( today there is 16 blocks merged in parallel) , and it seems to solve the problem

            I will make it configurable soon ( today it's a parameter in the code 😰 )

              @florent I see the fix-s3-merge branch is gone. I updated to current master (commit d8e01) and delta backup S3 is not working (same problem as before).

                @olivierlambert @florent The s3.js program has different code between the fix-s3-merge branch and master.

                      @Andrew yes The timeout are not fixed for now, only the nosuchkey

                      the fix will allow you to at least let you set a custom concurrency limit or maybe to calculate a value in a smarter way

                          @Andrew yes, we will reduce default concurrency while waiting for the parametrized version

                          here is the branch if you want to test it https://github.com/vatesfr/xen-orchestra/pull/6400

                          also , can you monitor the minio resource usage ? I'm curious to where is the bottleneck during a rename ( cpu / ram or disk usage)

                          fbeauchamp opened this pull request in vatesfr/xen-orchestra

                          closed fix(vhd-lib/merge): reduce concurrency to protect slower backends #6400

                            @florent Limiting concurrency did not fix my S3 backup problem, but it's working again after updating the build. So I guess it's resolved.
