Archiving Snapshots and Root Pool Recovery. By default, a ZFS file system is automatically mounted when it is created. You can determine specific mount-point behavior for a file system as described in this section. You can also set the default mount point for a pool's file system at creation time by using zpool create 's -m option. You can override the default mount point by using the zfs set command to set the mountpoint property to a specific path.
ZFS automatically creates the specified mount point, if needed, and automatically mounts the associated file system. The mountpoint property is inherited. To prevent a file system from being mounted, set the mountpoint property to none.
In addition, the canmount property can be used to control whether a file system can be mounted. For more information about the canmount property, see The canmount Property.
File systems can also be explicitly managed through legacy mount interfaces by using zfs set to set the mountpoint property to legacy. Doing so prevents ZFS from automatically mounting and managing a file system.
For more information about legacy mounts, see Legacy Mount Points. When you change the mountpoint property from legacy or none to a specific path, ZFS automatically mounts the file system. If ZFS is managing a file system but it is currently unmounted, and the mountpoint property is changed, the file system remains unmounted. Any file system whose mountpoint property is not legacy is managed by ZFS. In the following example, a file system is created whose mount point is automatically managed by ZFS:.
When the mountpoint property is changed, the file system is automatically unmounted from the old mount point and remounted to the new mount point. Mount-point directories are created as needed. If ZFS is unable to unmount a file system due to it being active, an error is reported, and a forced manual unmount is necessary. You can manage ZFS file systems with legacy tools by setting the mountpoint property to legacy.
ZFS does not automatically mount legacy file systems at boot time, and the ZFS mount and umount commands do not operate on file systems of this type. The following examples show how to set up and manage a ZFS file system in legacy mode:. The device to fsck and fsck pass entries are set to - because the fsck command is not applicable to ZFS file systems.
ZFS automatically mounts file systems when file systems are created or when the system boots. Use of the zfs mount command is necessary only when you need to change mount options, or explicitly mount or unmount file systems.
ZFS quick command reference with examples
The zfs mount command with no arguments shows all currently mounted file systems that are managed by ZFS. Legacy managed mount points are not displayed.
For example:. You can use the -a option to mount all ZFS managed file systems. Legacy managed file systems are not mounted. By default, ZFS does not allow mounting on top of a nonempty directory. Legacy mount points must be managed through legacy tools.
An attempt to use ZFS tools results in an error. When a file system is mounted, it uses a set of mount options based on the property values associated with the file system.
The correlation between properties and mount options is as follows:. When file systems are created on the NFS server, the NFS client can automatically discover these newly created file systems within their existing mount of a parent file system. If any of the mount options described in the preceding section are set explicitly by using the -o option with the zfs mount command, the associated property value is temporarily overridden. These property values are reported as temporary by the zfs get command and revert back to their original values when the file system is unmounted.Zones provides a means of virtualizing operating system services, allowing one or more processes to run in isolation from other activity on the system.
A zone is a "sandbox" within which one or more applications can run without affecting or interacting with the rest of the system. You can configure non-global zones with a shared-IP address or an exclusive-IP address. The shared-IP zone shares a network interface with global-zone and the exclusive-IP zone does not share network interface with global-zone. In this example, I'm using a shared-IP zone on the test box.
Zones enable more efficient resource utilization on your system. Dynamic resource reallocation permits unused resources to be shifted to other containers as needed. Processes that are assigned to different zones are only able to communicate through network APIs. It's mounted in local zone in read-only mode. To change this behavior. For applications running within zones, agents run entry points inside the zones.
VCS supports non-global zones in both secure and non-secure cluster environments. If VCS is running in a secure environment using Symantec Product Authentication Service, communication from non-global zones to global zones is secure.
Use hazonesetup to configure the zone under VCS. You may want to share a VxFS filesystem between multiple zones. For example, if a configuration file is available in a particular file system and this. The value of dir is a directory in the non-global zone. The value of special is a directory in the global zone to be mounted in the non-global zone.
Use this method only when you want shared read-only access to the file system. Exclusive access of a VxFS file system can be delegated to a non-global zone by direct mounting the file system in the non-global zone.ZFS quick command reference with examples. Here is the some of the advantages listed below.
Advantages: 1. Zpool Capacity of zettabytes 2. ZFS snapshots,clones and Sending-receiving snapshots 3. Lightweight filesystem creation 4. Encryption 5. Software RAID 6. Data integrity. Integrated Volume management No need an additional volume manager. Disadvantages: 1. No way to reduce the zpool capacity 2. Here i would like to share some of the basis ZFS commands syntax.
I hope it will help you to begin on ZFS administration. To Create a simple zpool. To create a mirror zpool:. To Create a raidz zpool:. In this second task we are going to see how to create new dataset under zpool.

To set manual mount point: If you want to set specific mount point for zfs dataset,use the below command. To share dataset through NFS: We can share the zfs dataset by modifying the zfs attribute. You can enable it using zfs set command. To create dataset under dataset:. Setting reservation to dataset:. Setting quota to dataset:. To check the zpool status:.
If it is disbale,enable the service through the following command.To set manual mount point: If you want to set specific mount point for zfs dataset,use the below command.
To share dataset through NFS: We can share the zfs dataset by modifying the zfs attribute. To compress dataset ZFS has default compression option. You can enable it using zfs set command. To create dataset under dataset:. Setting reservation to dataset:. Setting quota to dataset:. To check the zpool status:. If it is disbale,enable the service through the following command.
This is the example, zeepool is an existing two-way mirror that is transformed to a three-way mirror by attaching c2t1d0, the new device, to the existing device, c1t1d0. To check the pool integity Like fsck in UFS zpool scrub datapool i. Replacing Devices zpool replace datapool c0t0d0 c0t0d1 In the above example, the previous device, c0t0d0, is replaced by c0t0d1.
The -a option can be used to mount all ZFS managed filesystems. Legacy managed filesystems are not mounted. If the sharenfs property is off, then ZFS does not attempt to share or unshare the filesystem at any time.
