mount: you must specify the filesystem type
Try
mount -t ext4 /dev/sda2 /mnt/mountpoint
sh: copy: not foundDid I really write copy? The command is cp.

Apparently it's not ext4. Try ext3 instead.

Right. So sda2 doesn't contain a valid ext[12345] volume. (ext5 doesn't exist, AFAIK, and ext1 was called ext. Don't know if that is still supported. ext2 is old).Your first post on June 17 tells md0 contains an ext[234] filesystem, and your last post on June 18 tells sda2 is (the only) member of md0. So I must be mistaken in my assumption that the start of the partition is also the start of the filesystem.Can you post the output of
mdadm --examine /dev/sd?2
How old was the existing raid array, before you converted it?0 -

As you can see it is created in 2012, andt uses metadata version 0.90.00, while your linear array sdb2, created in 2019, uses metadata version 1.2. So apparently ZyXEL switched default metadata version somewhere in this years.That matters, as you can read here. For 0.9 the header is at the end, and for 1.2 the header is at the start. So if the firmware converted an 0.9 linear array to an 1.2 raid1 array by simply re-creating the array, it has overwritten the start of the filesystem.I think that can be repaired, ext3/4 is quite a robust filesystem, but repairing a filesystem from an wrong assumed data start is not a good idea, of course.Do you have an extra (external?) harddisk of at least 1TB which could be used? In that case we could create a bit-by-bit copy of the disk from the start of the partition, and try to repair that, and if that fails create a copy from the current start of the filesystem, and try to repair that.
