NAME SUNW.qfs - Resource type implementation for the Sun QFS shared file system in an Oracle Solaris Cluster environment AVAILABILITY SUNWqfs DESCRIPTION The SUNW.qfs resource type implementation supports the Sun QFS shared file system installed in an Oracle Solaris Cluster environment. It defines a failover resource for the shared file system's metadata server (MDS). The Sun QFS shared file system must be configured to use Sun Cluster did devices in the mcf(4) file. Additionally, the Oracle Solaris Cluster node-private hostnames (see scconf(1M)) must be used in the shared hosts file (see hosts.fs(4)) for the host IP addresses. Standard Properties See r_properties(5) for a complete description of the following resource properties: Validate_timeout Minimum: 60 Default: 180 Boot_timeout Minimum: 30 Default: 300 Prenet_start_timeout Minimum: 60 Default: 300 Fini_timeout Minimum: 60 Default: 120 Update_timeout Minimum: 60 Default: 120 Retry_Count Maximum: 10 Default: 2 Tunable: Anytime Retry_Interval Maximum: 3600 Default: 300 Tunable: Anytime Thorough_probe_interval Maximum: 3600 Default: 60 Tunable: Anytime FailOver_Mode Default: SOFT Tunable: Anytime Thorough_Probe_Interval Maximum: 3600 Default: 60 Tunable: Anytime Extension Properties QFSFileSystem Type: string array Default: none Tunable: Anytime This property lists the mount points of the file systems under the control of the resource type. The mount points must appear in the /etc/vfstab file. The associated file systems must be samfs file systems. Monitor_retry_count Default: 4 Tunable: Anytime This property controls the restarts of the fault monitor. This property indicates the number of times that the fault monitor is restarted by the Process Monitor Facility (PMF) and corresponds to the -n option passed to the pmfadm(1M) command. The number of restarts is counted in a specified time window (see the property Monitor_retry_interval). Note that this property refers to the restarts of the fault monitor itself, not the Sun QFS daemons. Monitor_retry_interval Default: 2 Tunable: Anytime This property indicates that the failures of the fault monitor are counted and corresponds to the -t option passed to the pmfadm(1M) command. If the number of times the fault monitor fails exceeds the extension property Monitor_retry_count, the fault monitor is not restarted by the process monitor facility. Probe_timeout Default: 120 Minimum: 2 Tunable: Anytime This property indicates the time out interval (in seconds) that the probe method is allowed. Child_mon_level Default: -1 Tunable: Anytime This property indicates to the PMF monitor the level of child process monitoring indicated. -1 disables child monitoring; Values of zero or larger enable PMF -C monitoring of the specified level. EXAMPLES Example 1. A shared hosts file. This example shows a shared hosts file for file system sqfs1, an already existing, unmounted, idle file system, and replacing its shared hosts file with one suitable for use with the SUNW.qfs agent. example# samsharefs -R sqfs1 # # Host file for family set 'sqfs1' # # Version: 4 Generation: 317 Count: 3 # Server = host 0/ash, length = 83 # ash ash-qfe0 1 - server elm elm-qfe0 2 - oak oak-qfe0 3 - example# cat /etc/opt/SUNWsamfs/hosts.sqfs1 # # Host file for 'sqfs1' # ash clusternode1-priv 1 - server elm clusternode2-priv 2 - oak clusternode3-priv 3 - example# samsharefs -uR sqfs1 # # Host file for family set 'sqfs1' # # Version: 4 Generation: 318 Count: 3 # Server = host 0/ash, length = 110 # ash clusternode1-priv 1 - server elm clusternode2-priv 2 - oak clusternode3-priv 3 - example# samd config Example 2. Instantiating a Failover MDS Resource. This example assumes that the data service is installed. This example instantiates a failover Sun QFS MDS resource named qfs-rs in a resource group named qfs-rg. The qfs-rg resource group is assumed to contain at least one logical host name resource, which identifies the logical host names associated with the resource group. example# scrgadm -a -t SUNW.qfs example# scrgadm -a -g qfs-rg -j qfs-rs -t SUNW.qfs \ -x QFSFileSystem=/global/qfs1,/global/qfs2 The qfs-rg resource group must contain a valid Sun QFS mount point as its QFSFileSystem property. NOTES The mount point provided must be the mount point of a Sun QFS shared file system. The file system should be mounted on all resource nodes when the resource group is brought online. Sun QFS file systems that are not shared must use the HAStoragePlus resource type.
