I am running SVN v140 of IOMeter with the O_DIRECT fix (which gives the correct NFS bandwidth measurement). However, running the build on a Linux machine with a mounted SMB share gives the following error:
Set_Sizes: Open on "/smb_test_mount/iobw.tst" failed (error Invalid argument).
There is no such error when using IOMeter 1.1.0rc1 (But, in that, NFS bandwidth measurement has too much cache effect).
My platform is:
Hyper-V VM running CentOS 6.2 x86_64
I will be happy to provide any further information, if necessary.
