Hi List,
I'm trying to get numbers for LSI's CacheCade2.0 feature in block mode. I do record a fio run with this job-file:
UltraBitch CC-testing # cat cc-create.fio
[global]
disable_lat=1
disable_clat=1
disable_slat=1
clat_percentiles=0
size=${SIZE}G
nice=10
prio=5
ioengine=libaio
iodepth=16
direct=1
iomem_align=4M
verify=crc32c-intel
verify_async=2
do_verify=1
verify_dump=1
[iSCSI]
rw=randwrite
bsrange=4k-4M
filename=${ISCSI_DEVICE}
write_iolog=iolog_${SIZE}.log
write_bw_log=creator_${SIZE}
The variables SIZE are properly set ISCSI-DEVICE. fio records a _bw.log and an iolog.log as one would think. BUT: it does never verify written data - is that intended?
I'm trying to replay this test after enabling CC2 with this jobfile:
UltraBitch CC-testing # cat cc-test.fio
[global]
disable_lat=1
disable_clat=1
disable_slat=1
clat_percentiles=0
#size=${SIZE}
nice=10
prio=5
ioengine=libaio
iodepth=16
direct=1
iomem_align=4M
verify=crc32c-intel
verify_async=2
do_verify=1
#verify_dump=1
[iSCSI]
read_iolog=iolog_${SIZE}.log
replay_no_stall=1
replay_redirect=${ISCSI_DEVICE}
write_bw_log=testor_${RUN}_${SIZE}
But those tests fail with the following error and I do not understand the reason.
iSCSI: (g=0): rw=read, bs=4K-4K/4K-4K, ioengine=libaio, iodepth=16
fio 2.0.3

Run status group 0 (all jobs):
fio: file hash not empty on exit
What might be the problem, how can I get a few figures?
P.S.: the array is attached via iSCSI, with a proper MPIO setup.
