I have an arm64 VM running FreeBSD 14.0 on Oracle's cloud. When I attach an external drive as a para-virtualized device the following messages are logged (these are also logged on reboot):
The attached storage otherwise works fine and is quite performant. I see no errors during normal usage after the initial attachment.
What do these errors mean, and should I do something to remediate them?
