most failstates arent worth preserving in a SMB environment. In larger environments or ones equipped for it a snapshot can be taken before rebooting- should the issue repeat.

Alternatively, if it doesn't happen again it's not worth fixing, if it does happen again then you can investigate it when it happens again.
