Hi, A nice bug on Windows : My profile is : [global] thread [random_read] rw=randread size=1024m directory=c:\temp\fio\read bs=32k fio start looks like : C:\Program Files\fio>fio.exe H:\fio\fio.win fio: c is not a directory fio: failed parsing directory=c:\temp\fio\read fio: job random_read dropped fio: file:options.c:875, func=lstat, error=No such file or directory Of course ! The : separator of the multi directory support feature does not filter the Windows drive letter Seb Sébastien BOUCHEX BELLOMIÉ Infovista® Server Technical Lead, Service Assurance R&D -- 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
