Hi, I lost one of my disk in a gmirror, so I inserted a fresh one. And thusfar things went rather smoothly,it started rebuilding automagically. That's good,but what isn't is: Jul 31 16:43:15 www kernel: ad2: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=16344448 Jul 31 16:43:15 www kernel: GEOM_MIRROR: Synchronization request failed (error=5). mirror/mirror[READ(offset=8368291840, length=131072)] Jul 31 16:43:40 www kernel: ad2: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=16910976 Jul 31 16:43:40 www kernel: GEOM_MIRROR: Synchronization request failed (error=5). mirror/mirror[READ(offset=8658354176, length=131072)] and ad2 is the original disk. So somewhere I'm left with corrupt files. And what's worse, once this happens, geom_mirror does not continue with the remainder of the disk... It claims it is, but there is no activity at all on the disks. So what to do???? Hard way out would be to make a backup, reinstall the basic system with another/second fresh harddisk, and recover the backup. But that is a lot of work. Why doesn't geom_mirror continue with the remainder of the disk? --WjW
