Each device can fall into one of the following states:
ONLINE
The device or virtual device is in normal working order. While some transient errors might still occur, the device is otherwise in working order.
DEGRADED
The virtual device has experienced failure but is still able to function. This state is most common when a mirror or RAID-Z device has lost one or more constituent devices. The fault tolerance of the pool might be compromised, as a subsequent fault in another device might be unrecoverable.
FAULTED
The device or virtual device is completely inaccessible. This status typically indicates total failure of the device, such that ZFS is incapable of sending or receiving data from it. If a top-level virtual device is in this state, then the pool is completely inaccessible.
OFFLINE
The device has been explicitly taken offline by the administrator.
UNAVAIL
The device or virtual device cannot be opened. In some cases, pools with UNAVAIL devices appear in DEGRADED mode. If a top-level virtual device is unavailable, then nothing in the pool can be accessed.
REMOVED
The device was physically removed while the system was running. Device removal detection is hardware-dependent and might not be supported on all platforms.
The health of a pool is determined from the health of all its top-level virtual devices. If all virtual devices are ONLINE, then the pool is also ONLINE. If any one of the virtual devices is DEGRADED or UNAVAIL, then the pool is also DEGRADED. If a top-level virtual device is FAULTED or OFFLINE, then the pool is also FAULTED. A pool in the faulted state is completely inaccessible. No data can be recovered until the necessary devices are attached or repaired. A pool in the degraded state continues to run, but you might not achieve the same level of data redundancy or data throughput than if the pool were online.
