You must ignore the VALUE and WORST columns for drive temp. These are "normalized" values only the smartmon idiots understand. The actual temp of 45C is a bit high, but well within the operating range for that drive. The WDC drives have a max temp (failure) of 80C IIRC, and a normal max operating temp of 65C. So you don't need to worry about this drive's temp. > The logs from the restart show > Jan 7 17:19:09 markov kernel: [ 2.928055] ata2.00: SATA link down (SStatus 0 SControl 0) > Jan 7 17:19:09 markov kernel: [ 2.928102] ata2.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) > Jan 7 17:19:09 markov kernel: [ 2.944459] ata2.01: ATA-8: WDC WD2003FYYS-02W0B1, 01.01D02, max UDMA/133 > Jan 7 17:19:09 markov kernel: [ 2.220056] ata1.00: SATA link up 3.0 Gbps (SStatus 123 SControl 300) > Jan 7 17:19:09 markov kernel: [ 2.220103] ata1.01: SATA link down (SStatus 0 SControl 310) > Jan 7 17:19:09 markov kernel: [ 2.228670] ata1.00: ATA-8: ST3750330NS, SN05, max UDMA/133 > the SATA link down messages > sound a little odd. No mystery here. These ports (links) are down because no drives are connected to them, apparently. Show full dmesg output, and tell us the SAS/SATA controller and port count on each for the system in question. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
