Hi Jorge. I tested nfstest_cache on the lastest kernel,there were some FAIL in the result.(It failed with all versions of nfs) Is this the cache's bug? Or i missed some arguments ? ./nfstest_cache --nfsversion=4 -e /nfsroot --server 192.168.227.10 --client 192.168.227.12 >cache4.log (version 3,4.1,4.2 had the same result). *** Verify consistency of data caching with NFSv4 on a directory acdirmin = 10 TEST: Running test 'acdirmin_data' FAIL: Directory listing should have not changed at t=0 FAIL: Directory listing should have not changed just before acdirmin PASS: Directory listing should have changed just after acdirmin TIME: 10.308059s *** Verify consistency of data caching with NFSv4 on a directory acdirmin = 10 acdirmax = 20 TEST: Running test 'acdirmax_data' FAIL: Directory listing should have not changed at t=0 FAIL: Directory listing should have not changed just before acdirmax PASS: Directory listing should have changed just after acdirmax FAIL: Directory listing should have not changed just before acdirmin PASS: Directory listing should have changed just after acdirmin TIME: 1m0.623938s *** Verify consistency of data caching with NFSv4 on a directory actimeo = 10 FAIL: Directory listing should have not changed at t=0 FAIL: Directory listing should have not changed just before actimeo PASS: Directory listing should have changed just after actimeo TIME: 11.027872s Huan Xu -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
