I hate to be a newbie on this list, and ask a question but I am really at a loss. I have a raid 10 that I have had working and was throwing no errors, and I rebooted and now I cannot get it to come back. I am running a live CD and trying to get it to mount, and I am getting errors about bad superblocks, invalid bitmaps, and invalid partition tables. I have been scouring the interwebs for the last few days and ran across the archive on http://www.spinics.net but cannot find anything that has worked there for me so I figured I would join and at least hope. Last chance for me to take it to a data retrieval office which I really don't want to do. Here is my setup. 4x1tb disks in raid 10. I can get the array to mount - but it tells me the file system is invalid. I have the following from commands I have seen people ask below. The devices are currently sitting unmounted and not in an array until I can go forward with some confidence I am not going to loose my data. mint dev # mdadm --examine /dev/sd[abde] /dev/sda: MBR Magic : aa55 Partition[0] : 1953521664 sectors at 2048 (type 83) /dev/sdb: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : 5a2570f4:0bbaf2d4:8a3cc761: 69b655ba Name : mint:0 (local to host mint) Creation Time : Wed Nov 14 20:55:09 2012 Raid Level : raid10 Raid Devices : 4 Avail Dev Size : 1953263024 (931.39 GiB 1000.07 GB) Array Size : 1953262592 (1862.78 GiB 2000.14 GB) Used Dev Size : 1953262592 (931.39 GiB 1000.07 GB) Data Offset : 262144 sectors Super Offset : 8 sectors State : clean Device UUID : e955cd6f:96e08ba2:c40bddae:ac633f0d Update Time : Wed Nov 14 21:15:27 2012 Checksum : 5b7c4f1e - correct Events : 9 Layout : near=2 Chunk Size : 512K Device Role : Active device 1 Array State : .A.A ('A' == active, '.' == missing) /dev/sdd: Magic : a92b4efc Version : 1.2 -- 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
