Creating new ZFS filesystems

[cah]

Code: Select all

mkdir /apps

zfs create rpool/apps
zfs set mountpoint=/apps rpool/apps
zfs set quota=10G rpool/apps

zfs get all rpool/apps

NOTICE: At least one pool has to be created first before any filesystems can be created. In this case, the rpool was created when installing the OS. zpool is used to create new pools with devices.

Increase quota from 10GB to 20 GB on /export/home file system:

Code: Select all

zfs set quota=20G rpool/export/home

After quota change, get all values from the file system:

%zfs get all rpool/export/home

From global zone (orazone01), create mount point for non-global zone oradev05:

Code: Select all

cd /zonepool/zones/oradev05/root
mkdir oradev05_vol
zfs create oracledatapool/oradev05_vol
zfs set mountpoint=/zonepool/zones/oradev05/root/oradev05_vol oracledatapool/oradev05_vol
zfs set quota=300G oracledatapool/oradev05_vol
zfs get all oracledatapool/oradev05_vol

The quota has been configured on this newly created file system.

I then logged onto oradev05 to see if I need to mount the file system.
On non-global zone (oradev05):

Code: Select all

The new file system has already been mounted. I checked /etc/vfstab and it does NOT have the entry in there. It must be mounted automatically.

If unmount is needed, try the following command in global zone:

Code: Select all

zfs unmount oracledatapool/oradev05_vol

If device is busy, force can be applied:

Code: Select all

zfs unmount -f oracledatapool/oradev05_vol

Legacy umount provides the same power on zfs mount points:

Code: Select all

umount oracledatapool/oradev05_vol

Vice versa, manual mount command is:

Code: Select all

zfs mount oracledatapool/oradev05_vol
