got a mdadm puzzler

[gene heskett <gheskett@shentel.net>]

Greetings all;

I just had a bad time rebooting with 2 combined problems.

1. A brand new acer wireless mouse was found of on powerups, but refused 
to move the pointer even in the bios, until that mouse was replaced with 
and older logiteh, and the cable leading to its rx dongle was plugged 
into a usb2 interface on the mobo. Its not found if plugged into a usb3 
port.

2. I've had since the last of about 20 installs of bullseye, a very early 
boot message about ata6 at the 10 and 20 second marks of the reboot  IF 
it was not a full powerdown reboot.
3. My home partition is I believe, ata6, which is 4 Samsung EVO-870 1T 
ssd's supposedly assembled as raid10, but recent reboots are mentioning a 
raid6.

So how do I go about querying mdadm to determine whats going south here? 
The man pages are quite verbose, but I can't seem to find how to query 
what it has, without supplying the device names of all drives that s/b 
part of the array. 

And why do I see the ata6 error on a reboot, but not on a full powerdown 
reboot?

This is my first experience at software raid, so I am a new bee. My 
fingers are at your command.

Thank you.

Cheers, Gene Heskett.
