Choosing maxAllowedIOError is arbitrary and prone to errors, when drives might be perfectly capable of taking I/O with only few locations return I/O error. This is a hindrance of sort where backend filesystems like ZFS can automatically fix and handle these scenarios. The added problem with current approach that we take the drive offline, making it virtually impossible to bring it online without restart the server which is not desirable on a busy cluster. Remove this state such that let the backend return error appropriately to caller and let the caller decide what to do with the error.
