ext2-fs sdb1 previous i/o error to superblock detected Flora Vista, New Mexico

If you really want to, there's a donate button at the bottom of the page. I have now bookmarked your site. And my fault was that i want to test the performance with: dd if=/dev/zero of=/dev/md0 bs=1G count=1 oflag=direct, after that i realised that all my data a somewhere ;( now i Reply Link Phillip October 7, 2009, 5:06 pmAwesome.

For this though, we just need the partition number, such as /dev/sda3 or /dev/hdb1. The lettering system in /dev for block devices is not guaranteed; in other words your /dev/sda could be /dev/sdb the next boot.*edit: made saving data the first step. The output you described is the ‘correct' output for a corrupted superblock. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck

Follow him on Twitter. UPDATE heap table -> Deadlocks on RID Why is absolute zero unattainable? Thanks again for your help. If the device is valid and it really contains an ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck

I just wanted the OS to boot. fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb1 and e2fsck reports a similar error: $ sudo e2fsck /dev/sdb1 Password: e2fsck 1.42 (29-Nov-2011) e2fsck: Superblock invalid, trying backup blocks... all with the same e2fsck error message. Could any body tell me what is this and how could I get rid of it?

I believe we will be able to mount the fs using a diff super block "only" if we r running system in rescue mode with cd media mounted, I could not Zurücksetzen? What's the most recent specific historical element that is common between Star Trek and the real world? So that I can confirm is there any data loss or not.Thanks in advance Satish Amrutwar Reply Link Manish December 21, 2015, 8:30 pmHi !

That maybe the superblock for the md device though. >.< Might be worth trying a few more superblocks, and trying to mount the raid device between attempts. 89 qurczak on January Code: Jan 1 04:00:13 kernel: scsi 0:0:0:0: Direct-Access IC25N060 ATMR04-0 0014 PQ: 0 ANSI: 0 Jan 1 04:00:13 kernel: sd 0:0:0:0: Attached scsi generic sg0 type 0 Jan 1 04:00:13 kernel: Recovery flag not set in backup superblock, so running journal anyway.

With a little bit luck you can find some fragments of your lost files in the lost+found directory of the sda1 partition. What is a type system? the only drama i seem to have encountered is that whatever stuffed up my system also made a mess of my postgresql install too, seemed to nuke a few files needed On the plus side - I have two hard drives so I have two attempts.Testdisk has a function to locate superblock backups on ext file systems, you may want to give

thanks Caro 43 Smess on March 27, 2011 said: My projects are recovered! There are four partitions - 2 are RAID components, one ‘unknown' and the last one says ‘3TB'. After a couple of days of searching for answers and failed restore attempts, including redhat tech support, I was able to recover my 16TB partition with the TestDisk link. 81 evidex I've also ran a testdisk deep search if anyone can decypher the log.

Jan 1 04:00:28 kernel: JBD2: I/O error detected when updating journal superblock for sda1-8. what do you think? the information of "the device is gone" or "has problems" should be logged by every layer from the bottom up to the top However I am only able to see the I have this problem..

And I see this is not the case with asus routers. You can't solve everyone's problem, but I think you are the only one willing to give it a go. Actually I don't need it, I just want easy optware install. and running testdisk /dev/loop0, I didn't find anything interesting.

yes According to the instructions I'm supposed to reboot and see if the partition can be correctly read. But this takes even more time! But first came to other help pages and messed up the rescue a bit. And afterwards we can't boot the system anymore.

Is it "eĉ ne" or "ne eĉ"? (Somewhat) generalised mean value theorem Are there any rules or guidelines about designing a flag? I need my sdb1's data back plz help me 59 Rogério Madureira on July 5, 2011 said: Thank you very much for the reply.
