Clearing Transient Errors
If the device errors are deemed transient, in that they are unlikely to effect the future health of the device, then the device errors can be safely cleared to indicate that no fatal error occurred. To clear error counters for RAID-Z or mirrored devices, use the zpool clear command. For example:
# zpool clear tank c1t0d0
This syntax clears any errors associated with the device and clears any data error counts associated with the device.
To clear all errors associated with the virtual devices in the pool, and clear any data error counts associated with the pool, use the following syntax:
# zpool clear tank
For more information about clearing pool errors, see [Clearing Storage Pool Devices].
