How to check PVE boot disk integrity

[kwat]

I am running PVE 7.3-4. Trying to image my boot disk with clonezilla always fails. I'd like make sure the problem is not with my system before
going to the clonezilla forums. Toward that end, I'd like to know if running fsck is the way to check my boot disk? I am suspicious since clonezilla
runs successfully on another PVE I have. Here is the output of the lsblk command:

Just wanted to provide an update. I was never able to get clonezilla to run without error so I deleted the lvm-thin storage from the boot disk and now I can back it up with out error. The was something like "Broken image. Image was corrupt or could not be checked".
