Adding file system or disk devices to a non-global zone is an integral part of creating a zone. We can add different types of file systems, raw devices and disk devices as well to a non-global zone. The post describes one of the most common ways of adding different file systems, raw and disk devices to a non-global zone.
Adding a Raw Disk device
We can either add a slice or a complete raw disk to the non global zone. In case of a full disk use s2 slice or else use any other slice you want to add.
global # zonecfg -z zone01 zonecfg:zone01> add device zonecfg:zone01:device> set match=/dev/rdsk/c0t0d0s6 zonecfg:zone01:device> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01>exit
Adding a VxFS file system
1. Adding a VxVM file system
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set type=vxfs zonecfg:zone01:fs> set special=/dev/vx/dsk/datadg/datavol zonecfg:zone01:fs> set raw=/dev/vx/rdsk/datadg/datavol zonecfg:zone01:fs> set dir=/data zonecfg:zone01:fs> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
2. Adding a VxVM raw volume
global# zonecfg -z zone01 zonecfg:zone01> add device zonecfg:zone01:device> set match=/dev/vx/rdsk/dg1/vol1 zonecfg:zone01:device> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
Adding UFS file system
1. Adding UFS under SVM
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set dir=/u01 zonecfg:zone01:fs> set special=/dev/md/dsk/d100 zonecfg:zone01:fs> set raw=/dev/md/rdsk/d100 zonecfg:zone01:fs> set type=ufs zonecfg:zone01:fs> add options [nodevices,logging] zonecfg:zone01:fs> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
2. Adding UFS under VxVM volume
We can also create a UFS file system on a VxVM volume as foillows.
global # vxassist -g datadg make datavol 1g global # mkfs -F ufs /dev/vx/rdsk/datadg/datavol global # mount -F ufs /dev/vx/dsk/datadg/datavol /zones/zone01/root/data
To add the UFS under VxVM :
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set type=ufs zonecfg:zone01:fs> set special=/dev/vx/dsk/datadg/datavol zonecfg:zone01:fs> set raw=/dev/vx/rdsk/datadg/datavol zonecfg:zone01:fs> set dir=/zones/zone1/root/data zonecfg:zone01:fs> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
Adding ZFS
1. Adding a ZFS file system to a non-global zone – Make sure the mount point property of the ZFS file system getting added to a zone is set to legacy, otherwise it may get assigned to multiple non-global zones simultaneously.
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set type=zfs zonecfg:zone01:fs> set special=rpool/data zonecfg:zone01:fs> set dir=/data zonecfg:zone01:fs> end zonecfg:zone01> verify zonecfg:zone01> commit zonecfg:zone01> exit
2. Adding ZFS file system as a loopback file system (lofs)to a non-global zone :
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set special=rpool/data zonecfg:zone01:fs> set dir=/data zonecfg:zone01:fs> set type=lofs zonecfg:zone01:fs> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
global # mkdir -p /zoneroot/zone01/root/data global # mount -F lofs rpool/data /zoneroot/zone01/root/data
3. Delegating a dataset to a non-global zone – here you have a complete control of the dataset you delegate to the non-global zone. For example you can create your own child datasets under the dataset you delegate and set properties of the delegated dataset etc. The ZFS file system data will be available as a pool in the non-globa zone.
global # zonecfg -z zone01 zonecfg:zone01> add dataset zonecfg:zone01:dataset> set name=rpool/data zonecfg:zone01:dataset> end zonecfg:zone01> commit zonecfg:zone01> verify zonecfg:zone01> exit
3. Adding ZFS volumes to non-global zones
global # zonecfg -z zone01 zonecfg:zone1> add device zonecfg:zone1:device> set match=/dev/zvol/dsk/rpool/datavol zonecfg:zone1:device> end zonecfg:zone1> verify zonecfg:zone1> commit zonecfg:zone1> exit
Adding a CD-ROM to non-global zone
To adda a CD-ROM to the non-global zone :
global # zonecfg -z zone01 zonecfg:zone01> add fs zonecfg:zone01:fs> set dir=/cdrom zonecfg:zone01:fs> set special=/cdrom zonecfg:zone01:fs> set type=lofs zonecfg:zone01:fs> end zonecfg:zone01> verify zonecfg:zone01> commit zonecfg:zone01> exit
