거래소 UUID를 찾는 방법

급습을 조직하고 있어요. 설치 중에 사용하기 위해 다음과 같이 sda파티션 테이블을 복사했습니다 .sdasdb

$ sudo sfdisk -dL /dev/sda > partition_table_sda
$ sudo sfdisk /dev/sdb < partition_table_sda

그러나 나는 sda스왑 공간에 UUID가 있지만 sdb그렇지 않다는 것을 알았습니다.

$ sudo blkid
/dev/sda5: UUID="vvvvvvvv-wwww-xxxx-yyyy-zzzzzzzzzzzz" TYPE="swap" 
/dev/sda1: UUID="vvvvvvvv-wwww-xxxx-yyyy-zzzzzzzzzzzz" TYPE="ext4" 
/dev/sdb1: UUID="vvvvvvvv-wwww-xxxx-yyyy-zzzzzzzzzzzz" TYPE="ext4"

하지만 파티션은 올바른 것 같습니다. 단지 uuid가 누락된 것뿐입니다.

$ sudo fdisk -l

그렇다면 스왑 공간에 uuid를 할당하는 방법은 무엇입니까 sdb5? 아니면 이미 UUID가 있는 경우 어떻게 인쇄할 수 있나요?
