fsvoladm(1M)fsvoladm(1M)NAMEfsvoladm - VxFS volume administration utility
The utility performs administrative tasks, such as adding, removing,
resizing, and encapsulating volumes in a specified VERITAS File System.
mount_point specifies the directory on which the file system is
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,
Adds a volume to a file system. The new space is available for alloca‐
Removes an encapsulated volume from a file system
and restores the original contents of the volume. This opera‐
tion 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
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 infor‐
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.
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 giga‐
bytes 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:
