Hello RAID-Experts, I have three RAID5 consisting of different partitions on 3 disks (Debian stable) running the root-filesystem on a md (/boot is a separate non-raid partition) which is running rather nicely. For convenience I plugged all drives into the first ide controller making them hda, hdb and hdc. So far, so good. The partitions are flagged "fd", i.e. Linux raid autodetect. As I have another builtin-ide-controller onboard, I'd like to distribute the disks for performance reasons, moving hdb to hde and hdc to hdg. The arrays would then consist of drives hda, hde and hdg. This should not be a problem, as the arrays should assemble themselves using the superblocks on the partitions, shouldn't it? However, when I switch one drive (hdc), the array starts degraded with two drives present because it is still looking for hdc, which of course now is hdg. This shouldn't be happening. Well, then I re-added hdg to the degraded array, which went well and the array rebuilded itself. I now had healthy arrays consisting of hda, hdb and hdg. But after a reboot the array was degraded again and the system wanted its hdc drive. And yes, I edited /boot/grub/device.map and changed hdc to hdg, so that can't be the reason. I seem to be missing something here, but what is it? -- YT, Michael - 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
