#922 closed patch (fixed)

-l devstat does not work if gp devstat log is 256 sectors

Reported by: oddbondboris Owned by: Christian Franke
Priority: minor Milestone: Release 7.0
Component: smartctl Version:
Keywords: ata Cc:

Description

smartctl does not use the 9 bit value from the directory properly and instead reads the value 256 as zero

Steps to reproduce:
smartctl -l devstat /dev/sdX on any drive that has a directory such as this

0x04       GPL     R/O    256  Device Statistics log

Expected behavior:
print device statistics
patched version shown

#smartctl -l devstat /dev/sdd

Device Statistics (GP/SMART Log 0x04) not supported

fix:
included patch, enable already existing code to parse >8bit values in GetNumLogSectors? when reading gplog devstat logs.

Does this device actually support Device Statistics page 255 (Vendor Specific Statistics) ?

If possible, please provide smartctl [-q noserial] -x -l devstat,0 ... sample output for an affected device.

another drive that exhibits similar behavior unpatched, i'll try to get output of devstat,0 and run patched (i don't have access to this one but might be able to get it's owner to run it)
