NFSTEST_CACHE(1)				 nfstest_cache 1.0.1				     NFSTEST_CACHE(1)

NAME
nfstest_cache - NFS client side caching tests
SYNOPSIS
nfstest_cache --server <server> --client <client> [options]
DESCRIPTION
Verify consistency of attribute caching by varying acregmin, acregmax, acdirmin, acdirmax and actimo. Verify consistency of data caching by varying acregmin, acregmax, acdirmin, acdirmax and actimo. Valid for any version of NFS.
OPTIONS
--version show program's version number and exit -h, --help show this help message and exit -f FILE, --file=FILE Options file -s SERVER, --server=SERVER Server name or IP address -p PORT, --port=PORT NFS server port [default: 2049] --nfsversion=NFSVERSION NFS version [default: 4] --minorversion=MINORVERSION Minor version [default: 1] -e EXPORT, --export=EXPORT Exported file system to mount [default: '/'] -m MTPOINT, --mtpoint=MTPOINT Mount point [default: '/mnt/t'] --datadir=DATADIR Data directory where files are created [default: ''] -o MTOPTS, --mtopts=MTOPTS Mount options [default: 'hard,rsize=4096,wsize=4096'] -i INTERFACE, --interface=INTERFACE Device interface [default: 'eth0'] -v VERBOSE, --verbose=VERBOSE Verbose level [default: 'none'] --nocleanup Do not cleanup --rmtraces Remove trace files [default: remove trace files if no errors] --keeptraces Do not remove any trace files [default: remove trace files if no errors] --createlog Create log file --bugmsgs=BUGMSGS File containing test messages to mark as bugs if they failed --ignore Ignore all bugs given by bugmsgs --nomount Do not mount server --basename=BASENAME Base name for all files and logs [default: automatically generated] --tverbose=TVERBOSE Verbose level for test messages [default: '1'] --filesize=FILESIZE File size to use for test files [default: 32] --nfiles=NFILES Number of files to create [default: 2] --rsize=RSIZE Read size to use when reading files [default: 4096] --wsize=WSIZE Write size to use when writing files [default: 4096] --iodelay=IODELAY Seconds to delay I/O operations [default: 0.1] --offset-delta=OFFSET_DELTA Read/Write offset delta [default: 4096] --warnings Display warnings --nfsdebug=NFSDEBUG Set NFS kernel debug flags and save log messages [default: ''] --rpcdebug=RPCDEBUG Set RPC kernel debug flags and save log messages [default: ''] --sudo=SUDO Full path of binary for sudo [default: '/usr/bin/sudo'] --tcpdump=TCPDUMP Full path of binary for tcpdump [default: '/usr/sbin/tcpdump'] --iptables=IPTABLES Full path of binary for iptables [default: '/sbin/iptables'] --messages=MESSAGES Full path of log messages file [default: '/var/log/messages'] --tmpdir=TMPDIR Temporary directory [default: '/tmp'] --runtest=RUNTEST Comma separated list of tests to run [default: 'all'] --client=CLIENT Remote NFS client that mounts server used for multiple client tests --client-port=CLIENT_PORT NFS server port for client to mount [default: value given in 'port' option] --justbefore=JUSTBEFORE Time in seconds to test a condition just before it is expected to come true [default: 2] --acmin=ACMIN Comma separated values to use for acregmin/acdirmin/actimeo [default: 10] --acmax=ACMAX Comma separated values to use for acregmax/acdirmax, first value of acmin will be used as acreg- min/acdirmin [default: 20]
TESTS
acregmin_attr Verify consistency of attribute caching by varying the acregmin NFS option. The cached information is assumed to be valid for attrtimeo which starts at acregmin. acregmax_attr Verify consistency of attribute caching by varying the acregmax NFS option. The cached information is assumed to be valid for attrtimeo which starts at acregmin. An attribute revalida- tion to the server that shows no attribute change doubles attrtimeo up to acregmax. An attribute revalidation to the server that shows a change has occurred resets it to acregmin. acdirmin_attr Verify consistency of attribute caching by varying the acdirmin NFS option. The cached information is assumed to be valid for attrtimeo which starts at acdirmin. Test that this is so. acdirmax_attr Verify consistency of attribute caching by varying the acdirmax NFS option. The cached information is assumed to be valid for attrtimeo which starts at acdirmin. An attribute revalida- tion to the server that shows no attribute change doubles attrtimeo up to acdirmax. An attribute revalidation to the server that shows a change has occurred resets it to acdirmin. actimeo_attr Verify consistency of attribute caching by varying the actimeo NFS option. The cached information is assumed to be valid for attrtimeo which starts and ends at actimeo. acregmin_data Verify consistency of data caching by varying the acregmin NFS option. acregmax_data Verify consistency of data caching by varying the acregmax NFS option. The cached information is assumed to be valid for attrtimeo which starts at acregmin. An attribute revalida- tion to the server that shows no attribute change doubles attrtimeo up to acregmax. An attribute revalidation to the server that shows a change has occurred resets it to acregmin. acdirmin_data Verify consistency of data caching by varying the acdirmin NFS option. The cached information is assumed to be valid for attrtimeo which starts at acdirmin. Test that this is so. acdirmax_data Verify consistency of data caching by varying the acdirmax NFS option. The cached information is assumed to be valid for attrtimeo which starts at acdirmin. An attribute revalida- tion to the server that shows no attribute change doubles attrtimeo up to acdirmax. An attribute revalidation to the server that shows a change has occurred resets it to acdirmin. actimeo_data Verify consistency of data caching by varying the actimeo NFS option. The cached information is assumed to be valid for attrtimeo which starts and ends at actimeo.
EXAMPLES
Required options are --server and --client $ nfstest_cache --server 192.168.0.11 --client 192.168.0.20 Testing with different values of --acmin and --acmax (this takes a long time) $ nfstest_cache --server 192.168.0.11 --client 192.168.0.20 --acmin 10,20 --acmax 20,30,60,80
NOTES
The user id in the local host and the host specified by --client must have access to run commands as root using the 'sudo' command without the need for a password. The user id must be able to 'ssh' to remote host without the need for a password.
