1. The (0,4) and (0,5) two extents logic disks take ineffectiveness:
2. The “smart” information of the (0,4) disk displays there are 1449 bad slots, as the following displayed:
The reason of the (0,4) disk is invalid is there are rather many bad slots, the number of IO which has delayed more than 10s in 30 minutes reaches at 10, so the system consider it is a slow disk and then separate it from the other.
3. The reason of the (0,5) disk is invalid is the hard disk returning back the 5101 (AMNF：Address Mark Not Found) error bit, this error has been discarded in the ATA-8 protocol, but the ** has been used, and finally causes the IO which reading the (0,5) disk failed and can’t be redden and written;
This error bit has displayed in the “smart” information, it is “Aborted Command” in the log:
