Attaching and Detaching Devices in a Storage Pool. Onlining and Offlining Devices in a Storage Pool. Archiving Snapshots and Root Pool Recovery. The following sections describe different scenarios for creating and destroying ZFS storage pools:. Creating and destroying pools is fast and easy.

The zpool command configures ZFS storage pools. A storage pool is a collection of devices that provides physical storage and data replication for ZFS datasets. All datasets within a storage pool share the same space. See zfs 8 for information on managing datasets. For an overview of creating and managing ZFS storage pools see the zpoolconcepts 7 manual page. All subcommands that modify state are logged persistently to the pool in their original form. The zpool command provides subcommands to create and destroy storage pools, add capacity to storage pools, and provide information about the storage pools. The following subcommands are supported:. Available pool properties listed in the zpoolprops 7 manual page. The following command creates a pool with a single raidz root vdev that consists of six disks:. The following command creates a pool with two mirrors, where each mirror contains two disks:.

That manual page also describes the subclasses and event zpool that can be generated.

With no arguments, the zpool list command displays the following information for all pools on the system:. The amount of physical space allocated to all datasets and internal metadata. Note that this amount differs from the amount of disk space as reported at the file system level. You can also gather statistics for a specific pool by specifying the pool name. For example:. Specific statistics can be requested by using the -o option.

Connect and share knowledge within a single location that is structured and easy to search. Sorry for asking an Ubuntu concerning question, but I hope that someone here has some experience with that. I have to mount the zfs pool I created with freenas8 on Ubuntu. I tried as it was described in this archived Link. I was able to run this command without errors:. If you run the command sudo zfs get all it should list all the properties of you current zfs pools and file systems.

AMD recommend beta blockchain drivers. Nvidia only tested on If a benchmark fails you either need to run in precise mode or the miner does not work with your cards correctly. If your cards fail a benchmark in precise mode Example: Sgminer for neoscrypt then it is not compatible with your driver version so in this case just un check the box for the failed benchmark and all will be fine, the other option is to use DDU and install the recommended driver version. Currently supports everything except BCH for the Payout coin. If you cards fail a benchmark in precise mode Example: Sgminer for neoscrypt then it is not compatible with your driver version which is why I added Legacy GatelessGate. So in this case just un check the box for sgminer neoscrypt and all will be fine. Skip to content. You signed in with another tab or window. Reload to refresh your session.

Additional columns can be added to the zpool status and zpool iostat output with -c. Otherwise, it will sync only the specified pool s. Sorted by: Reset to default. Specific statistics can be requested by using the -o option. You can create a double-parity or triple-parity RAID-Z configuration by using the raidz2 or raidz3 keyword when creating the pool. All rights reserved. However, better performance might be possible by using separate intent log devices, such as NVRAM or a dedicated disk. Connect and share knowledge within a single location that is structured and easy to search. This operation informs the underlying storage devices of all blocks in the pool which are no longer allocated and allows thinly provisioned devices to reclaim the space. The following command lists all available pools on the system. Consider the following points when determining whether setting up a ZFS log device is appropriate for your environment: Log devices for the ZFS intent log are not related to database log files. SIZE The total size of the pool, equal to the sum of the sizes of all top-level virtual devices.

The zpool command configures ZFS storage pools. A storage pool is a collection of devices that provides physical storage and data replication for ZFS datasets.

NFS and other applications can also use fsync to ensure data stability. See zpool-features 5 for details. If you try to create a pool with such a configuration, you see errors similar to the following: zpool create tank c1t0d0 mirror c2t0d0 c3t0d0 invalid vdev specification use '-f' to override the following errors: mismatched replication level: both disk and mirror vdevs are present zpool create tank mirror c1t0d0 c2t0d0 mirror c3t0d0 c4t0d0 c5t0d0 invalid vdev specification use '-f' to override the following errors: mismatched replication level: 2-way mirror and 3-way mirror vdevs are present You can override these errors with the -f option, but you should avoid this practice. Legal Notices. A pool created with multiple slices across disks is harder to manage than a pool created with whole disks. All rights reserved.

Before formatting a device, ZFS first determines if the disk is in-use by ZFS or some other part of the operating system. You can use similar output on your system to identify the actual ZFS commands that were executed to troubleshoot an error condition.
