Hi all. System: ubuntu 10.04 x32 and x64 I'm trying to use xtreemfs (distributed file system), which I got it successfully mounted (it uses fusermount, current version I have is 2.8.1), so I can write, read, (including gnome drap drog, etc) and do some file benchmarks using dbench (testing windows file server) to that mounted directory, without any problems. Also, I've used iozone benchmark without a problem, so it appears that the filesystem works fine. However, when I tried to run fio (including the latest version 1.44-rc1), I keep getting an 'Invalid argument error', I have no idea because this does not happen on other file systems, (e.g., nfs, etc) I think the error occurs somewhere getting the file information.. randread: (g=0): rw=randread, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1 Starting 1 process fio: pid=12627, err=22/file:filesetup.c:493, func=open(/media/xtreemfs/afile), error=Invalid argument So I've ran the --debug=all , and it appears that files are not found in 'hash' ?
