Asking the mailing list for help
There is a whole bunch of stuff you need to do first, before asking the list, however. And, studied carefully, this will hopefully enable you to solve your own problem.
smartctl
smartctl --all /dev/sda
Run smartctl on all drives. Most requests for help to the list turn out to be because the drives do not support TLER or SCT/ERC. This is easily fixed. If the --all option does not provide sufficient information, use the --xall option.
mdadm
mdadm --examine /dev/sda
Run --examine on all drives. This scans the drive for informtion about what arrays are on the drive.
mdadm --detail /dev/md0
Run --detail on all arrays. This scans the array for information about the drives or partitions which make it up.
lsdrv
Download Phil Turmel's lsdrv utility with
git clone git://github.com/pturmel/lsdrv.git lsdrv
It uses Python 2.7 so if your system defaults to Python 3 you will need to edit the shebang line, and then it should work fine. Run it and then save the output!
/proc/mdstat
cat /proc/mdstat
