ssd wearout n/a on pbs but on pve

hi folks,

- on my PVE cluster and the PBS the same version of smartmontools is installed (7.2-pve2)
- both have the same file in /var/lib/smartmontools/drivedb/drivedb.h
- for one model of ssd (crucial mx500) the PVE shows the wearout, but the PBS shows N/A.
- other disks wearout is shown as expected.

(all packages are up to date - non subscription repo)

as smartctl shows me the "Total_LBAs_Written", maybe its a calculation issue from the PBS gui?

do you have any ideas?

regards
stefan
