Ubuntu下使用tune2fs修改分区的uuid.md

August 11, 2021

• 参考
  • askubuntu.com - How do I change UUID of a disk to whatever I want?
  • CentOS / RHEL : How to change the UUID of the filesystem
  • How to change disk partition UUID in Linux

1. 先执行 e2fsck -f 之后才允许执行 tune2fs，否则会报错：This operation requires a freshly checked filesystem
sudo e2fsck -f /dev/{device}
2. 修改 uuid
   • 直接指定UUID
     tune2fs /dev/{device} -U {uuid}
   • 或者 随机生成UUID
     tune2fs /dev/{device} -U random
