Recovering a disk from QNAP failure

TL;DR: This is what I did to recover a drive (raid array mirrored) from QNAP hardware failure: &#xA; apt install mdadm lvm2&#xA;lvscan&#xA;vgscan&#xA;vgchange -ay vg288&#xA;lvs&#xA;mkdir /mnt/recover&#xA;mount /dev/vg288/lv1 /mnt/recover -o ro,user&#xA;cp -R /mnt/recover/share_folder /backup&#xA; (where vg288 is the volume listed in vgscan that your raid is on)
