You don't want to know. Anyway, I attempted to do tests on other i686 machines, similar but not identical. I did a lot of trials (dd if=/dev/zero of=/net/$HOST/mathtest/oink.dat bs=1M) with both kernel 3.11.10-11.1 and 3.11.10-0, The NFS client had 3.11.10-11.1 and mounted with Nfsvers=3 in /etc/nfsmount.conf. The target filesystem was ext3 but was actually a 1Gb file attached to a loop device, on both servers, whereas on Ocelot the bare metal was ext3. Hiss, boo. On 3.11.10-11.1, 77 trials. Most got EDQUOT (quota exceeded). Two got EIO (I/O error). 14 got Stale NFS Filehandle, but those shouldn't count because I removed the target file on the server before the client had closed it (even though the server was refusing to write anything because the user was over quota). (I messed up a test script.) I was hoping to get consistent misbehavior, which could then be shown to be cured by the test kernel, but that's not how it worked out. On 3.11.10-0, 12 trials, most got EDQUOT, one got EIO (I/O error). In all EDQUOT outcomes, writing was cut off exactly at the quota limit, although the files were sparse, i.e. the last written block was further along, sometimes quite a bit, i.e. over 1Gb when the quota was 750Mb. So the conclusion has to be, kernel 3.11.10-0 is no worse than 3.11.10-11.1, and given that you fixed a bug, we should move forward with this patch. But I'm afraid we haven't seen the last of the NFS problems. Next week when I can get at the original test machine (Ocelot) I'll re-test, and I'll post something if the results are significantly different from the above. If I hit something in the future and can come up with a procedure to reproduce it, I'll open a new bug. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
