Date: Fri, 27 Apr 2012 16:04:22 -0400 Message-ID: <4F9AFBC6.7070803@weboperative.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: "linux-raid@vger.kernel.org" List-Id: linux-raid.ids I have a strange issue on my raid10 8x400GB array. I cannot assemble my array anymore and it's gotten to a point that I don't know what to do to recover my data. I was hoping I could get some advice on it. Below is some info which I hope will help troubleshoot this issue. > mdadm -Esv ARRAY /dev/md/1 metadata=1.0 num-devices=0 UUID=828ed03d:0c28afda:4a636e88:7b29ec9f name=Darkside:1 spares=7 devices=/dev/sdg3,/dev/sdf3,/dev/sde3,/dev/sdd3,/dev/sdc3,/dev/sda3,/dev/sdb3 ARRAY /dev/md/1 level=raid10 metadata=1.0 num-devices=8 UUID=828ed03d:0c28afda:4a636e88:7b29ec9f name=Darkside:1 devices=8:131 > mdadm --version mdadm - v3.2.3 - 23rd December 2011 > for i in /dev/sd{a,b,c,d,e,f,g,i}; do fdisk -l ${i};done Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x4644f013 Device Boot Start End Blocks Id System /dev/sda1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sda2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sda3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e460f Device Boot Start End Blocks Id System /dev/sdb1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdb2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdb3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x7d10530f Device Boot Start End Blocks Id System /dev/sdc1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdc2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdc3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdd: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x81a213ab Device Boot Start End Blocks Id System /dev/sdd1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdd2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdd3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sde: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x4644f00e Device Boot Start End Blocks Id System /dev/sde1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sde2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sde3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdf: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x4644f00c Device Boot Start End Blocks Id System /dev/sdf1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdf2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdf3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdg: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x327d8d82 Device Boot Start End Blocks Id System /dev/sdg1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdg2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdg3 73779200 976773119 451496960 fd Linux raid autodetect Disk /dev/sdi: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e460f Device Boot Start End Blocks Id System /dev/sdi1 2048 2099199 1048576 82 Linux swap / Solaris /dev/sdi2 2099200 73779199 35840000 fd Linux raid autodetect /dev/sdi3 73779200 976773119 451496960 fd Linux raid autodetect > uname -r 3.3.3-gentoo Thanks in advanced.
