No known data errors The scrub operation is reading the data from ada0 and corrects all data that has a wrong checksum on ada1.
The pool can still be used, but some features are unavailable. This is indicated by the repairing output from zpool status. This example shows a mirrored pool consisting of two devices: If a drive goes offline or a read, write, or checksum error is detected, the error counter in status is incremented.
Resilvering is interruptible and safe. The last member of each mirror unless otherwise specified is detached and used to create a new pool containing the same data. One or more devices is currently being resilvered.
Note - If you had previously set the pool property autoreplace to on, then any new device, found in the same physical location as a device that previously belonged to the pool is automatically formatted and replaced without using the zpool replace command.
If the vdev does not have any redundancy, or if multiple devices have failed and there is not enough redundancy to compensate, the pool will enter the Faulted state. Bring the log device back online.
Consider whether the pool may ever need to be imported on an older system before upgrading. After the process has completed, the vdev will return to Online status. When an entire disk is replaced, the resilvering process takes time proportional to the amount of data used on disk. To replace the disk c1t3d0 with a new disk at the same location c1t3d0then you must unconfigure the disk before you attempt to replace it.
Each device in the pool is shown with a statistics line. The network link is much to my surprise, actually capable of filling the MB in about 5 seconds, leaving a lot of dead time during the whole process.
Updates Sept 1, Although additional vdevs can be added to a pool, the layout of the pool cannot be changed once the pool has been created, instead the data must be backed up and the pool recreated.

Apr 24, · I have another setup with 4K SSDs, ashift 12 and zpool block size K (This setup is running smoothly with a very good write speed, but the setup above is terrible) Click to expand and what is the diff between the 2 setups?
La commande zpool iostat permet d'effectuer une requête de statistiques d'E/S pour un pool ou des périphériques virtuels spécifiques. Cette commande est similaire à la commande iostat. Elle permet d'afficher un instantané statique de toutes les activités d'E/S, ainsi que les statistiques mises à jour pour chaque intervalle spécifié.
Added support to zpool iostat/status -c for user provided scripts. Added zpool scrub -p to pause/resume an active scrub.
