I hope someone can help with this weird issue I ran into.
I have a VM that suddenly began failing to start with this error:
Failed to operationname the virtual machine vmname. Error: The disk/snapshot resource with id resourcegroupname/providers/Microsoft.Compute/disks/osdiskname'>osdiskname cannot be resized down. Reducing disk/snapshot size is not supported in Azure to prevent data loss. If you do need to reduce the size of the disk, please create new snapshot/disks with the appropriate size. More information is available at https://aka.ms/AzureDisksFAQ. Target: '/subscriptions/subscriptionid/resourceGroups/resourcegroupname/providers/Microsoft.Compute/disks/osdiskname'.
This is really unexpected, because there have been no changes to any part of that VM since the last time it worked normally. I tried redeploying and reapplying, but those operations fail with the same error.
Anyone seen something like this or have any ideas?
