Not only. There is an UUID in the header of swap partitions (and files). Swap is not a file system. There is an UUID in the header of LVM physical volumes. PVs are not filesystems. > Of course, if the RAID system allows to attach individual "things" (perhaps > UUIDs?) to each of its components you could do that (no idea whether Linux > RAID allows that, though). Of course it does. MD raid devices contain both an UUID for the array and an UUID for the device. I will let somebody with more time than me to spend on find the right invocation of lsblk or other to print both. Regards, -- Nicolas George
