Hello,
I am trying to changing filename format, so run the below command to test it
fio --name=job --size=10m --numjobs=3
--filename_format=$jobname.$jobnum.$filenum
job: (g=0): rw=read, bs=(R) 4096B-4096B, (W) 4096B-4096B, (T)
4096B-4096B, ioengine=psync, iodepth=1
...
fio-3.12-17-g0fcbc0
Starting 3 processes
job: Laying out IO file (1 file / 10MiB)
fio: pid=0, err=21/file:filesetup.c:138, func=unlink, error=Is a directory
job: Laying out IO file (1 file / 10MiB)
fio: pid=0, err=21/file:filesetup.c:138, func=unlink, error=Is a directory
job: Laying out IO file (1 file / 10MiB)
fio: pid=0, err=21/file:filesetup.c:138, func=unlink, error=Is a directory
Run status group 0 (all jobs):
Got the above error, how to change the format of a file?
Then tired set the filename format like below and test works.
fio --name=job --size=10m --numjobs=3 --filename_format=test.$jobnum.$filenum

There is only one file has created --> test. .
3 process has run, why it not create 3 files?.
Thanks and Regards,
