tune2fs: Bad magic number in super-block while trying to open /dev/nvme0n1p3
|
|
/dev/nvme0n1p3 contains a crypto_LUKS file system
|
|
...
|
|
I expect you have to perform tune2fs on this /dev/mapper/xxx-xxx, there is the visible ext4 filesystem.
|
|
|
|
l /dev/disk/by-label
|
|
good
|
|
luks@ ⇒ ../../nvme0n1p2
|
|
root@ ⇒ ../../nvme0n1p1
|
|
bad
|
|
NO_LABEL@ ⇒ ../../nvme0n1p1
|
|
|
|
l /dev/mapper
|
|
before
|
|
control
|
|
after (by label)
|
|
luks@ ⇒ ../dm-0
|
|
and after that it is available:
|
|
/dev/dm-0
|
|
blkid
|
|
/dev/nvme0n1p2: UUID="..." LABEL="luks" TYPE="crypto_LUKS" PARTUUID="..."
|
|
after (by uuid)
|
|
luks-788e6b7d-18de-4c73-973a-27126348c4cb@ ⇒ ../dm-0
|
|
blkid
|
|
/dev/mapper/luks-...: UUID="..." BLOCK_SIZE="4096" TYPE="ext4"
|
|
|
|

|
For changing the file system UUID you have to decrypt /dev/sda1
|
|
sudo cryptsetup luksOpen /dev/disk/by-uuid/788e6b7d-18de-4c73-973a-27126348c4cb luks-788e6b7d-18de-4c73-973a-27126348c4cb
|
|
and then run tune2fs on the decrypted device mapper device.
|
|
|
|
To change the UUID of the LUKS volume, use cryptsetup luksUUID --uuid=<the new UUID> /dev/sda1.
