Hey Guys,
I've been running OMV for a couple weeks now, a mixture of 4 older 3TB WD Red drives, and 4 new 3TB WD Red drives, using SnapRaid and MergerFS to pool them.
But I've noticed weekly I get hard drive reports stating the ATA error count has increased,
Device: WDC_WD30EFRX-68EUZN0_WD-WMC4N1021445 [SAT], ATA error count increased from 5 to 6
Device: WDC_WD30EFRX-68EUZN0_WD-WCC4N4RR3U8L [SAT], ATA error count increased from 8 to 9
Device: WDC_WD30EFRX-68EUZN0_WD-WCC4N7TACJ0Z [SAT], ATA error count increased from 5 to 6
Device: WDC_WD30EFRX-68EUZN0_WD-WCC4N7TACULH [SAT], ATA error count increased from 3 to 4
Device: WDC_WD30EFRX-68EUZN0_WD-WCC4N0EP7C5R [SAT], ATA error count increased from 5 to 6
Device: WDC_WD30EFRX-68AX9N0_WD-WCC1T1153741 [SAT], ATA error count increased from 5 to 6
Device: WDC_WD30EFRX-68EUZN0_WD-WMC4N0942489 [SAT], ATA error count increased from 5 to 6
Device: WDC_WD30EFRX-68EUZN0_WD-WCC4N76L03FY [SAT], ATA error count increased from 9 to 10
I used to run a QNAP before OMV with 4 of the drives in Raid5, so these errors are definitely new.
I do understand a couple of my drives have a high Load_Cycle_Count. 2 out of 4 of my original WD Reds were from the batch that had the head park set to like 7 seconds, so they racked up quite a count.
As for my system, I'm running:
Intel Xeon E3-1220V3
SUPERMICRO MBD-X10SL7 (Flashed to IT mode for running the 8 x 3TB drives)
16GB Cruial DDR3 SDRAM ECC Unbuffered Ram (2 x 8GB Sticks)
Can anyone provide some insight or suggestions as to what might be happening, or if this is a concern? I don't see any Offline Uncorrectable errors or bad sectors, so that has to mean a good thing right? All my drives are within warrenty, including my 4 original ones (until the end of this year)
Any help or input is very much appreciated!
I'll post one of the smart results in a reply to this, as I'm running into Message Too Long to post.Scratch that, my reply don't seem to be showing up. Please find each drive's full Smart Extended Attributes attached here, with each filename being the drives serial number.
