Can you add Vdev to a pool?
You can add more vdevs to a zpool , and you can attach more disks to a single or mirror vdev .
How do I create a new Zpool?
To create a storage pool, use the zpool create command. This command takes a pool name and any number of virtual devices as arguments. The pool name must satisfy the naming requirements in ZFS Component Naming Requirements.
Can you remove a Vdev?
Top-level vdevs can only be removed if the primary pool storage does not contain a top-level raidz vdev, all top-level vdevs have the same sector size, and the keys for all encrypted datasets are loaded. Removing a top-level vdev reduces the total amount of space in the storage pool.
Can you add drives to a Raidz?
You can’t extend the existing raidz1 vdev by adding another disk but you can add another vdev to the pool to increase the pool’s capacity. You’ll need more than one additional disk if you want to retain redundancy. For example, you could use two disks to add a mirror vdev or 3+ disks for another raidz1 vdev.
How do I rename Zpool?
File systems can be renamed by using the zfs rename command….With the rename subcommand, you can perform the following operations:
- Change the name of a file system.
- Relocate the file system within the ZFS hierarchy.
- Change the name of a file system and relocate it within the ZFS hierarchy.
Can you expand ZFS pool?
Expanding ZFS-based storge can be relatively expensive / inefficient. For example, if you run a ZFS pool based on a single 3-disk RAIDZ vdev (RAID5 equivalent 2), the only way to expand a pool is to add another 3-disk RAIDZ vdev 1.
How do I create a new ZFS pools and file system?
How to Create ZFS File Systems
- Become root or assume an equivalent role with the appropriate ZFS rights profile.
- Create the desired hierarchy.
- Set the inherited properties.
- Create the individual file systems.
- Set the file system-specific properties.
- View the results.
How do I add a device to a zpool pool?
Adding Devices to a Storage Pool You can dynamically add disk space to a pool by adding a new top-level virtual device. This disk space is immediately available to all datasets in the pool. To add a new virtual device to a pool, use the zpool add command.
How to expand zpool after vdev?
Once the resilver completes, the old disk can be removed from the system. Once all disks in a vdev are replaced by larger ones, you can expand the pool by running zpool online -eor by having the autoexpandproperty set to on(though I wouldn’t really recommend the latter; pool expansion should be a conscious decision). So which way is better?
What is the format for specifying the virtual devices in zpool?
The format for specifying the virtual devices is the same as for the zpool create command. Devices are checked to determine if they are in use, and the command cannot change the level of redundancy without the-f option. The command also supports the-n option so that you can perform a dry run. For example:
