Standby Sup synchronization verification

Question

My redundant supervisor crashed sometime back. The following error was observed
%SYS-3-SYS_LCPERR3:Module 2: Bus Asic #0 out of sync error:
Module requires attention - troubleshoot or contact TAC for assistance
This problem was resolved later.
My question is how do i verify that my standby sup will function properly when the active one fails? This is a production network, can't bring it down for testing.
I tried to verify if the bootflash in module 2 had synchronized with the image in the active sup using the command
show flash 2/bootflash:
But this command gives me the message File system in use (8). Try again later.
Is this normal? should i be concerned?
Is there any other way to check if the standby sup will function properly in the event of the primary failing

Hello,
From the output you're seeing from the dir 2/bootflash: it appears that the bootflash is being locked by another process. I've provided a sample of the same outputs for your review from another switch to compare.
SR3-Cat6509a (enable) dir bootflash:
