Hello Dmitry, Thanks for reaching out. by "reproduced", you mean that you're getting the same error during randomread workloads using gfapi? This is the error that I'm getting on all the setups that I've tested (3x Replica & 2x Replica with Arbiter) during randomread + gfapi: failed fio extend file 4vm-1G-randrw.1.0 to 18446744073709551615

I didn't get the logic behind get_file_sizes(), but the job file definitely requests 1G ant not 18446744073709551615, which is -1ULL. Dmitry
