oh,

...
# pvs /dev/sda2
  Found duplicate PV b79x0kLXR9mAC0z0IZUxyJG1VC24Crl7: using /dev/md1 not /dev/sda2
  PV         VG     Fmt  Attr PSize PFree  
  /dev/md1   vg_sys lvm2 a--  1.36T 553.16G

# pvs /dev/sdb2
  Failed to read physical volume "/dev/sdb2"
...

smart status tells me

...
5 Reallocated_Sector_Ct   0x0033   001   001   036    Pre-fail  Always   FAILING_NOW 4095
...

smartd did not send warning mail, selftests are successful, only in the logfiles is

...
Device: /dev/sdb [SAT], FAILED SMART self-check. BACK UP DATA NOW! 
Device: /dev/sdb [SAT], Failed SMART usage Attribute: 5 Reallocated_Sector_Ct.
...

I think I will replace sdb.
