While trying to recover a directory from backup, I ran into an issue with duplicate uuids when trying to mount a recovered volume. The problem was the recovered volume had the same uuid as boot.
Here’s the original mount command I ran, but I was getting a wrong fs type error.
mkdir
mount -t xfs /dev/nvme3n1p2 /recover
mount: wrong fs type, bad option, bad superblock on /dev/nvme3n1p2,
missing codepage or helper program, or other error
It turned out to be a duplicated uuid. To get around this problem, I ran -o nouuid.
mount -t xfs -o nouuid /dev/nvme3n1p2 /recover
Once the files were recovered, I unmounted volume and detached it from the instance.
