An idea why it aborts _could_ be the fact that the Linux (kernel) NFS-serve= r=20 (there's also a userland NFS server, but that's not widely used, so I presu= me=20 this isn't the case for you) doesn't unlink files that are unlinked from=20 remote immediately, but moves them to a temporary (.nfs<someid>) name befor= e=20 finally truly unlinking them in case the file is still referenced by some N= =46S=20 handle (i.e., opened at the remote end), thus causing the directory to not = be=20 empty, even though all files in it have actually been unlinked from the=20 remote end. I don't know whether some performance/caching issues cause this, but as the= =20 temporary (seemingly) disappeared when bonnie++ was closed (and thus all fi= le=20 descriptors of bonnie among with any cache the OS kept freed), I'd guess in= =20 this direction. Again, this is just a wild guess, and I've never had problems running bonni= e++=20 on a Linux Kernel-NFS-server exported filesystem, but from Linux NFS-client= s,=20 that is, which might (or rather, will probably) behave differently. =2D-=20 Heiko Wundram Product & Application Development =2D------------------------------------ Office Germany - EXPO PARK HANNOVER =20 Beenic Networks GmbH Mail=E4nder Stra=DFe 2 30539 Hannover =20 =46on +49 511 / 590 935 - 15 =46ax +49 511 / 590 935 - 29 Mail wundram@beenic.net Beenic Networks GmbH =2D------------------------------------ Sitz der Gesellschaft: Hannover Gesch=E4ftsf=FChrer: Jorge Delgado Registernummer: HRB 61869 Registergericht: Amtsgericht Hannover
