The following describes the procedure for creating a file system.
The GFS Shared File System uses logical volumes of GDS as shared devices. The status of the logical volumes of GDS must be ACTIVE on each node.
GDS logical volume should be set up as follows.
- Set up the type of a disk class with which GDS logical volume belongs as shared.(Change GDS class attributes)
- Set all the nodes that share GFS Shared File System as the scope of the disk class to which logical volume belongs.(Change GDS class attributes)
For GDS disk class operations, see the applicable items under "Operation using Global Disk Services Management View" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide (Solaris(TM) Operating System)".
For the logical volume operations of GDS, see the applicable items under "Operation using Global Disk Services Management View" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide (Solaris(TM) Operating System)".
Click [Create] on the [Operation] menu and the [Create File System Wizard] screen appears. It is shown in the following "Figure Create File System Wizard (1)".
In the [Create File System Wizard (1)] screen, set the node information and enter the mount point.
In the [Node name], select the names of the sharing nodes. Be sure to select two nodes. It is not possible to deselect the local node.
In order to select host names other than the host names displayed, click the <Select> button then select the LAN host that will be used for each node in the following [Host Name Selection Wizard] screen. If you don't click the <Select> button, the displayed host name will be used.
Please choose the host name of LAN used from the left-hand side [Candidate host names]. Then please click the <Add> button in order to add to the right-hand side [Selection host names]. Note that only one host name can be selected at a time in [Selection host names]. If you want to change [Selection host names], delete the host name being selected in [Selection host names].
Specify the nodes on which the [Primary MDS] and [Secondary MDS] will be started. A single, unique node must be selected for each MDS.
Specify the full path name of a mount point in the [Mount point] field. If <yes> button is selected for [Make directory], a directory is created with the following attributes:
Owner: root
Group: sys
Access right: 775
After setting the area information items, click the <Next> button to proceed to the next screen which is shown in the following "Figure Create File System Wizard (2)".
To restore the settings to their default values, click the <Reset> button.
To cancel the file system creates operation, click the <Cancel> button.
After completing the MDS configuration, the register partition screen will be displayed. It is shown in the following "Figure Create File System Wizard (2)".
Select the partition from [Candidate partitions] field, and click the <Add> button. More than one partition can be selected at a time. However, cannot select a partition that is a part of existing file system or a management partition.
After selecting a partition, click the <Next> button to continue. The next screen is shown in "Figure Create File System Wizard (3)".
To cancel all selections of the partition currently displayed on [Component partitions] field, click the <reset> button.
To return to the [Create File System Wizard (1)] screen, click the <Back> button.
To cancel the file system creates operation, click the <Cancel> button.
If the GDS logical volume is not ACTIVE, it cannot be selected as a configuration partition. If it needs to be selected as a configuration partition, bring the logical volume into ACTIVE.
In the [Create File System Wizard (3)] screen, select the area (META/LOG/DATA) to be assigned to each partition selected in the [Create File System Wizard (2)].
The partition to which META is assigned becomes a representative partition.
For an explanation of the combinations of areas (META/LOG/DATA) assigned to partitions, see "2.1.6 Partition configuration".
After setting the area information items, click the <Next> button to proceed to the next screen which is shown in the following "Figure Create File System Wizard (4)".
To restore the settings to their default values, click the <Reset> button.
To return to the [Create File System Wizard (2)] screen, click the <Back> button.
To cancel the file system creation operation, click the <Cancel> button.
If you do not need to change extended information, detailed information and mount information, click the <Create> button to create the file system.
In the [Create File System Wizard (4)] screen, the [extended information] values should be set such that they allow for future expansion of the file system and configuration changes.
Set the maximum number of partitions and the maximum size of data area after adequately considering future data area expansion for the file system to be created. For details, see "4.2.5 For future expansion".
The above parameter for expansion setup corresponds to specific mkfs_sfcfs(1M) options of the GFS Shared File System as follows:
- [Maximum number of partitions]: maxvol=n
- [Maximum size of data area]: maxdsz=n
For details about the parameters, see mkfs_sfcfs(1M).
When the extended information items are correct, click the <Next> button to proceed. The next screen is shown in the following "Figure Create File System Wizard (5)".
To restore the settings to their default values, click the <Reset> button.
To return to the [Create File System Wizard (3)] screen, click the <Back> button.
To cancel the file system creation operation, click the <Cancel> button.
If you do not need to change the detailed information and mount information, click the <Create> button to create the file system.
In the [Create File System Wizard (5)], set the detailed information.
The above parameter for expansion setup corresponds to specific mkfs_sfcfs(1M) options of the GFS Shared File System as follows:
- [File System threshold]: free=n
- [V-data threshold]: mfree=n
- [Byte per i-node]: nbpi=n
- [Block per 1-extent]: nblkpext=n
- [Size of update log area]: logsz=n
For details about the parameters, see mkfs_sfcfs(1M).
The [File System threshold] is the value obtained by subtracting from 100 the minimum percentage of free area in the file system specified by the -o free option of mkfs_sfcfs(1M).
The [V-data threshold] is the value obtained by subtracting from 100 the minimum percentage of free area in the V-data area specified by the -o mfree option of mkfs_sfcfs(1M).
When the detailed information items are correct, click the <Next> button to continue. The next screen is shown in the following "Figure Create File System Wizard (6)".
To restore the settings to their default values, click the <Reset> button.
To return to the [Create File System Wizard (4)] screen, click the <Back> button.
To cancel the file system creation operation, click the <Cancel> button.
If you do not need to change the mount information, click the <Create> button to create the file system.
In the [Create File System Wizard (6)] screen, set the mount information.
The above each mount option corresponds to mount option of mount_sfcfs(1M) as follows:
- [setuid execution disabled]: nosuid
- [RO mount]: ro
- [noatime]: noatime
- [auto mount disabled]: noauto
For details about the parameters, see mount_sfcfs(1M).
After setting the mount information, click the <Create> button to create the file system.
To restore the settings to their default values, click the <Reset> button.
To return to the [Create File System Wizard (5)] screen, click the <Back> button.
To cancel the file system creation operation, click the <Cancel> button.
If you create a file system by clicking the <Create> button, the GFS Management View will automatically add an entry to /etc/vfstab.
Mount the file system.
For information on how to mount the file system using a command, see "11.2.4 Mount".
