I see.  I thought it was physical disks.  Yes, I have four logical volumes.

Thank you again for all your help.

The "dev253" entries are the logical volumes (or other device-mapper
devices), not the physical devices themselves.

I see you have three PVs in the volume group (sda1, sdb2 & sdc1), but

Just post the output of the "lvs" command if you're unsure.

Kind regards,
Bryn.
