Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

Note: Do not mount a multi-volume system with the ioerror=disable or
ioerror=wdisable mount options if the volumes have different availability
properties. Symantec recommends the ioerror=mdisable mount option both for
cluster mounts and for local mounts.
Creating multi-volume file systems
When a multi-volume file system is created, all volumes are dataonly, except
volume zero, which is used to store the file system's metadata. The volume
availability flag of volume zero cannot be set to dataonly.
As metadata cannot be allocated from dataonly volumes, enough metadata space
should be allocated using metadataok volumes. The "file system out of space"
error occurs if there is insufficient metadata space available, even if the df
command shows that there is free space in the file system. The fsvoladm command
can be used to see the free space in each volume and set the availability flag of
the volume.
Unless otherwise specified, VxFS commands function the same on multi-volume
file systems as the commands do on single-volume file systems.
