Veritas™ File System 5.0.1 Administrator's Guide

Note: Steps 5, 6, 7, and 8 are optional, and can be performed if you prefer to remove
the wrapper of the volume set object.
Converting to a single volume file system
1
Determine if the first volume in the volume set, which is identified as device
number 0, has the capacity to receive the data from the other volumes that
will be removed:
# df /mnt1
/mnt1 (/dev/vx/dsk/dg1/vol1):16777216 blocks 3443528 files
2
If the first volume does not have sufficient capacity, grow the volume to a
sufficient size:
# fsvoladm resize /mnt1 vol1 150g
3
Remove all existing allocation policies:
# fsppadm unassign /mnt1
4
Remove all volumes except the first volume in the volume set:
# fsvoladm remove /mnt1 vol2
# vxvset -g dg1 rmvol vset1 vol2
# fsvoladm remove /mnt1 vol3
# vxvset -g dg1 rmvol vset1 vol3
Before removing a volume, the file system attempts to relocate the files on
that volume. Successful relocation requires space on another volume, and no
allocation policies can be enforced that pin files to that volume. The time for
the command to complete is proportional to the amount of data that must be
relocated.
5
Unmount the file system:
# umount /mnt1
6
Remove the volume from the volume set:
# vxvset -g dg1 rmvol vset1 vol1
