    Description

      When attempting to run sgpdd-survey on raw devices it refuses to continue after sg_readcap, returning:

      read capacity(16): pass-through os error: Inappropriate ioctl for device
READ CAPACITY (16) failed: Inappropriate ioctl for device
sg_readcap failed: Inappropriate ioctl for device
sg_readcap on device localhost:/dev/raw/raw1 failed,  setting block size to 512
device localhost:/dev/raw/raw1 not big enough:  0 < 8388608.
Consider reducing $size

       

      In testing this could be bypassed by commenting out the relevant device size check (lines 217-221) and sgpdd-survey proceeds normally otherwise.
