I understand that option will impose a pretty large performance
overhead but it is currently a working trade-off/solution/workaround
;)  It is better to have that trade-off than having an unstable host
server for those of us who need LVM snapshots related... IMO.

Hopefully you or Konrad can have a look into the related codes and if
need some testers... I always will try my best to test any new patches
if available to test its stability in this... ...

Thanks.

Kindest regards,
