NFS mount definition is a list of arguments separated by a ':' given in the following order if positional arguments are used (see examples): ::export:nfsversion:port:proto:sec - \--cmpopts=CMPOPTS NFS mount options used for comparing test file other than the ones specified in --nfsopts \[default: 'hard'\] ## TESTS ### test01 ``` Verify data read from file is correct ``` ### test02 ``` Verify data written to file is correct ``` ### all ``` Run all tests: test01, test02 ``` ## EXAMPLES Use positional arguments with nfsversion=3 for second mount:\ nfstest\_fcmp -s 192.168.0.2 -e /exports --nfsopts :::3 Use named arguments instead:\ nfstest\_fcmp -s 192.168.0.2 -e /exports --nfsopts nfsversion=3 ## NOTES The user id in the local host must have access to run commands as root using the 'sudo' command without the need for a password. ## SEE ALSO **[nfstest.test\_util(3)](/nfstest.test_util/3.md),** **[nfstest\_alloc(1)](/nfstest_alloc/1.md),** **[nfstest\_cache(1)](/nfstest_cache/1.md),** **[nfstest\_delegation(1)](/nfstest_delegation/1.md),** **[nfstest\_dio(1)](/nfstest_dio/1.md),** **[nfstest\_file(1)](/nfstest_file/1.md),** **[nfstest\_interop(1)](/nfstest_interop/1.md),** **[nfstest\_io(1)](/nfstest_io/1.md),** **[nfstest\_lock(1)](/nfstest_lock/1.md),** **[nfstest\_pkt(1)](/nfstest_pkt/1.md),** **[nfstest\_pnfs(1)](/nfstest_pnfs/1.md),** **[nfstest\_posix(1)](/nfstest_posix/1.md),** **[nfstest\_rdma(1)](/nfstest_rdma/1.md),** **[nfstest\_sparse(1)](/nfstest_sparse/1.md),** **[nfstest\_ssc(1)](/nfstest_ssc/1.md),** **[nfstest\_xattr(1)](/nfstest_xattr/1.md),** **[nfstest\_xid(1)](/nfstest_xid/1.md)** ## BUGS No known bugs. ## AUTHOR Jorge Mora (mora@netapp.com)
