Error while extracting performance KPIs: 'disk_util' about virt-perf-scripts

[schrht]

There is something wrong in the source file: "gen1_SCSI_fs_read_4k_1_mnttmp_1.fiolog"

[cheshi@cheshi-laptop2 fio_result.rhel75]$ grep error gen1_SCSI_fs_read_4k_1_mnttmp_1.fiolog -B 2 | head -n 7
Starting 16 processes
gen1_SCSI_fs_read_4k_1_mnttmp_1: Laying out IO file (1 file / 512MiB)

The test failed and the disk_utils didn't show in the outputs, that's why we can't parse it.

Found the same issue in the following source files:

[cheshi@cheshi-laptop2 fio_result.rhel75]$ grep "err=21" * | cut -d: -f1 | uniq
gen1_IDE_fs_read_4k_1_hometmp_1.fiolog
gen1_IDE_fs_read_4k_8_hometmp_1.fiolog
gen1_SCSI_fs_read_4k_1_mnttmp_1.fiolog
gen1_SCSI_fs_read_4k_8_mnttmp_1.fiolog

These 4 files are the orphaned ones only exists in fio_result.rhel75.

In both fio_result.rhel74 and fio_result.rhel75, I can found the corresponding log files with a different name:

[cheshi@cheshi-laptop2 fio_result.rhel74]$ ls gen1_IDE_fs_read_4k_1_*_1.fiolog
gen1_IDE_fs_read_4k_1_mnt1tmp_1.fiolog
[cheshi@cheshi-laptop2 fio_result.rhel74]$ ls gen1_IDE_fs_read_4k_8_*_1.fiolog
gen1_IDE_fs_read_4k_8_mnt1tmp_1.fiolog
[cheshi@cheshi-laptop2 fio_result.rhel74]$ ls gen1_SCSI_fs_read_4k_1_*_1.fiolog

[cheshi@cheshi-laptop2 fio_result.rhel74]$ ls gen1_SCSI_fs_read_4k_8_*_1.fiolog
