Cannot unplug SR Citrix Hypervisor 8.2

[Radu Silviu-Ionut]

I have an old SR (iSCSI) that I have to upgrade all of its disks from HDD to SSD. But before do that, I want to sr-forget it. But I cannot.

I tried:

]# xe pbd-unplug uuid=a3d32d6f-c4e2-e928-a7c5-67275049e136
This operation cannot be performed because this VDI is in use by some other operation

I also tried to unplug VDI

# xe vdi-destroy uuid=a88fa7d3-1273-4f6f-87f9-6f4540e351d9
This operation cannot be performed because this VDI is in use by some other operation
vdi: a88fa7d3-1273-4f6f-87f9-6f4540e351d9 (WSDB 0)
operation: destroy

I looked in to my XenCenter and all the VDI are dom0. This SR have been used since XenServer 7.2 and servers were updated till today.

How can I make this SR be forgettable, in a secure manner?

 

Thank you

Hi, 

 

When Dom0 is locking the files, most of the times a reboot of the host is necessary. 

I also see that the Metadata is on there, please change the location of the metadata backup.

Hi,

 

Thank you for the answer.

I have rebooted two of the three hosts with no change in the Dom0 disks. They are the same, nothing changed.

I have changed the Backup Virtual Machine Metadata to the new SR through xsconsole and still my old SR is populated with the same disks.

I don't know how to approach this issue.

Please guide me to a documentation if you can.

 

Thanks again.

Why just two of the three hosts? Maybe the one you have not rebooted is the offender ?

Before I edited my above message, I have rebooted the third host too.

Still the same issue.
