HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device

hdparm 테스트 하는데

[root@test ~]# hdparm -tT /dev/mapper/isw_ciajbcfggd_Volume1p8

/dev/mapper/isw_ciajbcfggd_Volume1p8:

위와 같이 에러가 날경우 hdparm 버전이 낮아서 그렇다.

[root@test ~]# hdparm -v

Usage:  hdparm  [options] [device] ..

Options:

버전확인 해보니 6.6이다.

다운 받은후

[root@test ~]# tar-xvf hdparm-9.9.tar.gz

[root@test ~]# cd hdparm-9.9
