Hi - Reading the man page under ioengine, it mentions that sg will do asynchronous IO if the target is the sg character device. So I'm assuming that means a job file something like > cat sgtest.fio [global] bs=512b readwrite=read ioengine=sg size=1m [/dev/sg2] but when I run it, > uname -srp Linux 2.6.34-12-default x86_64 > ls -l /dev/sg2 crw-rw---- 1 root disk 21, 2 Aug 26 17:46 /dev/sg2 > ./fio --version fio 1.43.1 > sudo ./fio sgtest.fio /dev/sg2: (g=0): rw=read, bs=512-512/512-512, ioengine=sg, iodepth=1 Starting 1 process fio: pid=3147, got signal=11 Run status group 0 (all jobs): fio: file hash not empty on exit Any idea what I'm doing wrong or might be missing on the system?
