Running fsck with encrypted drive [SOLVED]

[jhanarato]

G'day,

I'm running LM 19.3 and I'd like to run a file system check. During installation I went with the fully encrypted root partition and I'm not sure how to run fsck in this situation.

Any help is appreciated.

Thanks Mike!

I put a 20.3 ISO on a USB stick, logged in and muddled my way through:

Code: Select all

mint@mint:~$ sudo su
]root@mint:/home/mint# cryptsetup luksOpen /dev/sda3
Command requires device and mapped name as arguments.
root@mint:/home/mint# cryptsetup luksOpen /dev/sda3 maindisk
Enter passphrase for /dev/sda3: 
root@mint:/home/mint# vgchange -aly
  2 logical volume(s) in volume group "mint-vg" now active
root@mint:/home/mint# ls /dev/mapper
control  maindisk  mint--vg-root  mint--vg-swap_1
root@mint:/home/mint# fsck.ext4 -nf /dev/mapper/mint--vg-root

The fsck check was pretty quick, I have a 500GB SSD. Looks pretty good eh?
