Clearing Transient Errors

If the device errors are deemed transient, in that they are unlikely to affect the future health of the device, they 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 c1t1d0

This syntax clears any device errors and clears any data error counts associated with the device.

To clear all errors associated with the virtual devices in a pool, and to clear any data error counts associated with the pool, use the following syntax:

# zpool clear tank
