So I have a box with 2x os drives(os, cent7) + 8 drives. I mkfs.btrfs all the 8 others drives, created a sub volume, put some files inside. Then I decide to reinstall the os. btrfs filesystem show shows, the disk is not empty. I mount it to a directory, it was successful, but the subvolume and the files are no where to be found. Am I missing the zfs import equivalent of btrfs here?
