Some days ago I found this in the logs: Apr 1 02:12:05 x2100 kernel: ad6: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=612960533 Apr 1 02:12:05 x2100 kernel: ad6: FAILURE - WRITE_DMA48 status=51 error=10 LBA=612960533 Apr 1 02:12:05 x2100 kernel: GEOM_MIRROR: Request failed (error=5). ad6[WRITE(offset=313835792896, length=4096)] Apr 1 02:12:05 x2100 kernel: GEOM_MIRROR: Device gm0: provider ad6 disconnected. Normally it looks like a disk error, but I think our half year old disks (WD RE2) shouldn't fail after this short time. Of course they have moving parts so they MAY fail. :( Yesterday I tried to reinit the sata channel and insert the disk back into the mirror. I got this: Apr 3 23:00:32 x2100 kernel: GEOM_MIRROR: Device gm0: provider ad6 detected. Apr 3 23:00:32 x2100 kernel: GEOM_MIRROR: Device gm0: rebuilding provider ad6. Apr 3 23:00:36 x2100 kernel: ad6: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=245760 Apr 3 23:00:38 x2100 kernel: ad6: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=392576 Apr 3 23:00:38 x2100 kernel: ad6: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=392960 Apr 3 23:00:53 x2100 kernel: ad6: FAILURE - device detached After this, the disk disappeared from the sata channel completely. The wierd is that we used the onboard nvidia-raid and the very same error occured, but there was no report in the kernel the machine just don't asked for operating system. Later I found out that the disk was forgotten ~2 weeks before that reboot (data was ~2 week old on it). Otherwise that "forgotten/failed" disk was also half year old and was fine without a problem. Is there anybody who experienced something similar with SUN X2100 or any other servers running FreeBSD 6 and sata? Regards, Andras
