xcp used dellr640 dis pool as vm store, 4TB, single disk. it was local SR.
Brought in trunas, set a SR device: /dev/sda, rebooted Dell, now VMs wont start.
Current issue:
Your SR metadata is partially lost.
Specifically:
The VDI files exist
But XAPI has lost the VM VDI attachment records (VBDs)
That is why:
SR scan complains
VMs have no disks
XO only shows “Other install media”
This is classic SR metadata desync, usually caused by:
SR delete/recreate
Interrupted SR introduce
xapi restart during SR changes...
How can I still use my current VM data?

I am deep in the chatGPT hole.
Any help is greatly warranted .
