Recovering from a failed vxresize shrink operation

The vxresize command operates on both the file system and the underlying volume. For a shrink operation, the vxresize command calls the fsadm command to resize the file system and then calls the vxassist command to resize the underlying volume. In some cases, the file system shrink operation succeeds but the volume shrink operation fails. This situation may occur if you specify an invalid medianame operand to the vxresize command. A medianame operand may be invalid if the disk does not exist or if the disk is not in the specified disk group. The vxresize command passes the invalid parameter to the vxassist volume resize operation, which then fails. A message is displayed similar to the following:

VxVM vxassist ERROR V-5-1-18606  No disks match specification 
for Class: dm, Instance: vmr720-10_disk_14
VxVM vxresize ERROR V-5-1-4703 Problem running vxassist command for 
volume vol1, in diskgroup testdg 

The operation results in a reduced file system size, but does not change the volume size. This behavior is expected; however, you need to correct the volume size to match the file system size.

Workaround:

Repeat the vxresize command with the required size but without any disk parameters. The file system is not resized again when the current file system size and new file system size are the same. The vxresize command then calls the vxassist command, which reduces the volume size. The file system size and the volume sizes are now the same.
