Geom mirror warning

[fluca1978]

Hi all,
I've configured geom to mirror a couple of SATA 250 GB Seagate Barracuda, but I've got a list of warnings as follows:

ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=9874455
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=17327503
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=9893999
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=9887279
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=12055951
ad6: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=1141295

Should I worry about? I mean, is my disk faulty and going to die or has just a few bad blocks?

Since the LBAs are different and don't repeat, it's more likely either a DMA bug, a controller issue, or a flaky SATA cable.

Can't rule out a flaky drive, but you can always pkg_add -r smartmontools and then run smartctl -a /dev/ad6

It can also run drive tests, it should print out a list of options if you just run 'smartctl'.
