fsvoladm - VxFS volume administration utility SYNOPSIS
[bias] DESCRIPTION
The utility performs administrative tasks, such as adding, removing, resizing, and encapsulating volumes in a specified VERITAS File Sys- tem. mount_point specifies the directory on which the file system is mounted. volname specifies the volume within the volume set. By default, size, bias, and newsize are specified in units of disk blocks bytes). However, you can append or to the number to indicate that the value is in kilobytes, megabytes, gigabytes, or terabytes, respectively. Keywords Adds a volume to a file system. The new space is available for allocation. Removes an encapsulated volume from a file system and restores the original contents of the volume. This operation can fail if there were significant changes to a file's allocations on disk since encapsulation. A volume encapsulated with a bias cannot be deencapsulated. Adds a volume to a file system, making the contents of that volume, starting from offset bias, available as a file instead of free space. The size of the encapsulated file is size - bias. bias must be smaller than size, and be a multiple of the file system block size. The default value of bias is 0. Displays the volumes in a file system. Removes a volume from a file system. Resizes one of the volumes in a file system. In some circumstances, the command cannot resize a 100% full file system due to lack of space for updating structural information. Check VxFS file systems on a regular basis; increase their size if they approach 100% capacity. This problem can also occur if the file system is very busy. Free up space or reduce activity on the file system and try the resize again. EXAMPLES
The following command adds the volume that is 10 gigabytes in size, to the file system The following command removes the volume from the file system The following command resizes the volume in the file system from its current size to 20 GB: The following command displays the volumes in the file system The following command encapsulates the volume The volume is ten gigabytes in size, resides in the file system and has the file name The following command de-encapsulates the volume that was encapsulated in the previous example: SEE ALSO
