        @sumansaha check the "Advanced" view of your SR, you'll see if there's VDI to coalesce and how much/which depth.

        Then, you should take a look at the SMlog to see if it's moving forward or not.

              This process is running behind.

                Actually no luck in removing the base files after removing the orphand disks.

                  So you have a coalesce process. It could take some time, leave it as is and NEVER remove a base copy manually.

                    Note that the coalesce process can take up to 24 hours. If there are issues, this article might be helpful: https://support.citrix.com/article/CTX201296/understanding-garbage-collection-and-coalesce-process-troubleshooting

                        @sumansaha In summary , I've deleted Orphan VDIs from Dashboard->health . But in deletion, I've maintained the sequence of their age.It has taken 6 hours, though that depends on the VM size.
