I booted with a LiveCD, which brought md0 up in the following configuration: md0 : active raid5 sdg1[4] sdf1[3] sde1[2] sdb1[0] 3907039744 blocks level 5, 64k chunk, algorithm 2 [5/4] [U_UUU] Unfortunately it also mounted it read/write. On a subsequent reboot back to my original install I'm getting: md_d0 : inactive sde1[2](S) 976759936 blocks And when I mdadm --assemble --scan -fv: md0 : active raid5 sdb1[0] sdg1[4] sdf1[3] sdc1[1] 3907039744 blocks level 5, 64k chunk, algorithm 2 [5/4] [UU_UU] md_d0 : inactive sde1[2](S) 976759936 blocks (note the odd drive out changed from sdc to sde) Any idea WTF is going on here? I already need to repair the filesystem on there because of this. When I mount it all my data is gone. This is extremely annoying to say the very least. -- Tony Arcieri -- 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
