I have one disk of a 2 disk raid1 array that failed in the raid device. The manufacturer and subsequent investigation indicates it is formatted as a linux disk.
fdisk -l displays
Device Start End Sectors Size Type /dev/sdb1 41 1953 1913 956.5K Microsoft basic data /dev/sdb2 ... ... /dev/sdb9 6504448 8503295 1998848 976M Microsoft basic data /dev/sdb10 8503296 7814035254 7805531959 3.6T Microsoft basic data
sudo mount /dev/sdb10 /media/seagate
mount: /media/seagate: unknown filesystem type 'linux_raid_member'.
Following the advice here I ran
sudo mdadm --assemble --run /dev/md0 /dev/sdb10
mdadm: /dev/sdb10 is busy - skipping
mdadm --examine produces

One final question was posted here but according to @Ian, the question was never answered satisfactorily.
I am at an impasse it seems. Can anyone point me in the right direction for mounting this partition and (hopefully) recovering the data on it?
Thanks in advance.
Well, made some headway. Used these instructions and I can see the LVM both in terminal window and in GUI interface.
mount /dev/vg8/lv8 /mnt/sd1
Generates: “Wrong fs type, bad option, bad superblock on /dev/mapper/vg8-lv8, missing codepage or helper program, or other error”
Followed the advice and used
But got message
/dev/vg8/lv8 contains a ext4 file system last mounted on /shares/public on Tue Sept 16 20:00:52 1975 Proceed anyway?
JerryFrey suggested using a file recovery such as foremost. But don't I have to mount the partition first?
