Hi Jens, First of all many thanks for this great tool! I wanted to test the performance of a samba network share with fio, file server access pattern. I can execute it on a local directory without any issue. Too bad, that is not the case when I run fio on a directory mounted from a samba share. I get this error: ste@ubuntu:~/.gvfs/fio on localhost$ ~/Downloads/fio-1.50/fio ~/iometer-file-access-server.ro --timeout=120 iometer: (g=0): rw=randread, bs=512-64K/512-64K, ioengine=sync, iodepth=64 fio 1.50 Starting 1 process fio: pid=4999, err=22/file:filesetup.c:495, func=open(iometer.1.0), error=Invalid argument Run status group 0 (all jobs): I even tried to use a normal sync engine, but the error is still there. Any idea? Many thanks in advance. -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
