ext2-fs md0 error unable to read superblock Elberfeld, Indiana

On the other drives examine says no RAID superblock on /dev/sdX. This also gives you some additional flexibility when replacing failed members. My /etc/sysctl.conf files have nothing in them about the hostname, and rc.sysinit is a system script automatically run at boot time, so I'd back out any changes there.

The closest thing I found to my problem was this thread, which suggested running mdadm --create /dev/md0 -v -l 5 -n 4 /dev/sda /dev/sdc /dev/sde /dev/sdd and checking for a valid They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

The first thing was just doing an e2fsck. cat /proc/mounts lists a line "/dev/md0 /mnt/md0 ext3 rw 0 0" 10. U kunt dan proberen een ander superblok te gebruiken, bijvoorbeeld: e2fsck -b 8193 [[email protected] etc]# sudo dumpe2fs /dev/md0 | grep superblock dumpe2fs 1.42.7 (21-Jan-2013) dumpe2fs: Ongeldig argument tijdens openen van /dev/md0[[email protected] IF you are still with me, could you look over my RAID notes.

Please also show the results of running the getinfo_disk.sh script from "How to provide information about your system". From the dmesg output you can see that it had to finish the reshape after you rebooted: [ 9.542918] md/raid:md0: raid level 5 active with 4 out of 5 devices, algorithm Consider it a birthday present😉 75 Amida_Kun on October 14, 2011 said: Estuve por lo menos dos horas intentando recuperar mis datos, ya al final di con tu post, y salvaste If anything, it's worth a shot. 107 Ted on June 6, 2012 said: [email protected]:~# fsck.ext4 -cDfty -C 0 /dev/sda5 e2fsck 1.42.3 (14-May-2012) ext2fs_open2: Bad magic number in super-block /sbin/e2fsck: Superblock invalid,

If you're running such an important "raid", maybe arch''s more stable "LTS" kernel would be a better/safer environment, since everything had worked before for you, and in future, would be worth

To try and save some time and since this is a second partition, not the boot partition, I think I should be able to attempt to mount the device.
