Hi, I have been trying to use gfapi to read files written using fio gfapi engine, but don't see anything getting read. When I check disk activity using iostat or low level tools for my PCIe SSD, there is no activity.
Is the below sequence of fio correct way of using it? Am I missing something? [root@vsan-blr4 prashanth]# fio --name=seq_write.1.0 --filename=seq_write.1.0 --rw=read --ioengine=gfapi --direct=1 --bs=4K --iodepth=1 --numjobs=8 --group_reporting --volume=pvol --brick=192.168.1.3 --time_based=40 --size=1G fio: time_based requires a runtime/timeout setting seq_write.1.0: (g=0): rw=read, bs=4K-4K/4K-4K/4K-4K, ioengine=gfapi, iodepth=1 ... fio-2.2.10 Starting 8 processes Jobs: 8 (f=0): [R(8)] [inf% done] [0KB/0KB/0KB /s] [0/0/0 iops] [eta 1158050441d:07h:00m:13s] [ Note: As soon as I start the fio job, I see a huge ETA number which seems fishy and fio exits in less than 5 seconds. ] Thanks Prashanth HGST E-mail Confidentiality Notice & Disclaimer: This e-mail and any files transmitted with it may contain confidential or legally privileged information of HGST and are intended solely for the use of the individual or entity to which they are addressed.
