Adding a New File System to a Volume

Procedure 5-1 To add a new file system to an existing volume

1. Select the volume to contain the file system.

2. Choose Actions > File System > New File System.

3. Complete the New File System dialog box as follows:

   File system type:	Select the file system type from the options shown.
   Create Options:	See Table 5-1 “Allocation Unit/Block size” for allocation and block and settings. To specify create details, click New File System Details and specify any additional options in the New File System Details dialog box (see Table 5-2 “Create Options”).
   Compress (checkbox)	If your platform supports file compression, then you can select Compress to compress the files on your file system.
   Mount Options:	Enter the mount point for the file system, if you want the file system mounted at system startup. Select the Create mount point checkbox if you want the system to create the mount point if it does not already exist. Select the Read only and Honor setuid checkboxes, as required. Select the Add to file system table and Mount at boot checkboxes to update the system table file and mount the file system at system startup. Select the Add to file system table checkbox, and leave the Mount at boot checkbox unselected to update the system table file, and not mount the file system at system startup. To specify mount details, click Mount File System Details and specify any additional options using the checkboxes and Extra Options entry in the Mount Details dialog box (see Table 5-3 “Mount Options”).

   After you have provided all necessary information in the dialog box, click OK.

   File System	Allocation Unit Values	Block Size Values
   ufs	512, 1024, 2048, 4096, 8192	4096, 8192
   vxfs	same as block size	1024, 2048, 4096, 8192
   jfs, jfs2	512, 1024, 2048, 4096	512, 1024, 2048, 4096
   ext2, ext3	1024, 2048, 4096	1024, 2048, 4096

   Table 5-2 Create Options

   Option	File Systems	Description

   logsize	vxfs	Activity logging area size.

    

   Table 5-3 Mount Options

   Option	File Systems	Description
   largefiles/nolargefiles	vxfs, jfs, fs2	File system contains/does not contain files equal or greater than 2 GBytes.
   Quick I/O (checkbox)	vxfs	Enables/disables the VERITAS Quick I/O for Databases option for the filesystem.
   QuickLog device (checkbox)	vxfs	Enables the filesystem to use VERITAS QuickLog. Select also the log device number to be used (1 to 31).
   Cluster mount (checkbox). This is present in the Mount File System Details dialog only if the optional cluster functionality is available.	vxfs	Mounts the filesystem in shared mode. Select the nodes to be mounted.
   log/delaylog/tmplog	jfs, jfs2	Controls intent logging. To maintain filesystem integrity after a system failure, logging must be enabled.
   blkclear	vxfs	Clears all data extents before file allocation.
   mincache	vxfs	File system caching policy Note that, while the tmpcache option to mincache improves performance, it reduces integrity.
   noatime	vxfs	Disables access timerecording.

    

   • The New File System task requires a file system type.

   • If the file system is to be mounted at startup, a file system mount point is required.

   • If the Add to file system table checkbox is selected, then the file system table is automatically updated when the file system is mounted.

   • The mount point must be an absolute pathname (that is, it must begin with /).
