Example of creating a multi-volume file system
The following procedure is an example of creating a multi-volume file system.
To create a multi-volume file system
1
After a volume set is created, create a VxFS file system by specifying the
volume set name as an argument to mkfs:
# mkfs -F vxfs /dev/vx/rdsk/rootdg/myvset
version 7 layout
327680 sectors, 163840 blocks of size 1024,
log size 1024 blocks largefiles supported
After the file system is created, VxFS allocates space from the different
volumes within the volume set.
2
List the component volumes of the volume set using of the fsvoladm
command:
# mount -F vxfs /dev/vx/dsk/rootdg/myvset /mnt1
# fsvoladm list /mnt1
devid size used avail name
0 10240 1280 8960 vol1
1 51200 16 51184 vol2
2 51200 16 51184 vol3
3 51200 16 51184 vol4
3
Add a new volume by adding the volume to the volume set, then adding the
volume to the file system:
# vxassist -g dg1 make vol5 50m
# vxvset -g dg1 addvol myvset vol5
# fsvoladm add /mnt1 vol5 50m
# fsvoladm list /mnt1
devid size used avail name
0 10240 1300 8940 vol1
1 51200 16 51184 vol2
2 51200 16 51184 vol3
3 51200 16 51184 vol4
4 51200 16 51184 vol5
