If the node has died, this information is no longer available, and so the
attachment cannot be cleaned up properly. Is there any way to handle this

Hi Eduard,
According to the error you had, I assume your volume format is sparse

the format to 'raw', which increases its size. I believe the 'size'

So while doubling the timeout will fix some cases, there will be cases with
