We did recently have a failed drive that finished rebuilding a few days ago.

Okay this is the error I get when I rescan all disk

SR_BACKEND_FAILURE_47(, The SR is not available [opterr=directory not mounted: /var/run/sr-mount/4e765024-1b4d-fca2-bc51-1a09dfb669b6], )

So when I grep this comes back.

24347 pts/4 S+ 0:00 _ grep --color=auto coalesce

And checking the XOA VDI to Coalesce page and I will see the progress?

I'm trying to migrate these servers off of this pool since this pool is having some sort issue with the VDI chain being overloaded, but when I try to migrate them it says the snapshot chain is too long. What does migrating have to do with snapshots when its two completely different actions?

And by a lot do you mean 1 day? 2 Days? 1 Week?

So is there a way to speed this up or do I just have to wait for it?

So in the ISCSI virtual disk storage pool 1 there are 606 items I do not see the option for coalesce at all. Here's some screenshots.

Also after researching I have found that there are 352 Items that need to be coalesce.

On the VDI to Coalesce page what is the Depth?

Also getting this log error on the Xen Orchestra Web Interface.[0_1629315103732_2021-08-18T19_31_00.542Z - XO.log](Uploading 100%)

SR_BACKEND_FAILURE_47(, The SR is not available [opterr=directory not mounted: /var/run/sr-mount/4e765024-1b4d-fca2-bc51-1a09dfb669b6], )

One question does the Xen Orchestra manager have to be ran on XCPNG or can get rid of XCPNG all together?

In the XCP-NG Center GUI we have 16 VM's with 41 snapshots currently in the snapshot section on the center.
