Description of problem: Windows Server 2019 guest paused after an IO error. Storage based on IBM Spectrum Scale, volumeModefilesystem and accessMode ReadWriteMany. How reproducible: Steps to Reproduce: 1. Start a Windows Server guest 2. Run some storage stress test. 3. VM paused because IO error. Version: Openshift 4.11.3 IBM Spectrum Scale 2.7
VM paused because of IO error is an expected behavior. And could you please describe the vm/vmi events to check when it started to pause
Are you able to resume the VM after paused by virtctl or UI? we need to understand why the IO error from the storage
By the way, the image size issue suggests another test: Boot the VM without configuration changes but increase the image size to a multiple of 4,096 bytes first (e.g. "truncate %4096 /path/to/disk0/disk.img"). If the guest runs successfully with just the image size change, then we can be fairly sure the issue is caused by the image size. Maybe some component should print a warning if the disk image is not a multiple of at least 512 bytes.
