Its reproducible, I hoped it wouldn't happen again after a reboot, but unfortunately it did. Trying a newer kernel, hmm, usually a problem on server systems. I will try to test quotas on another amd64 system first(*). Thanks for your help, Bernd (*) Which would be easy, if there wouldn't be a 64bit kernel, 32bit glibc, nfsclient inode truncation bug, which forces me to run all of our amd64 nfsroot-clients with a 32bit kernel, http://lkml.org/lkml/2005/2/28/172. Well, my fault that I still didn't submit a glibc bug report. -- Bernd Schubert PCI / Theoretische Chemie Universität Heidelberg INF 229 69120 Heidelberg
