Label missing or mounting issue from my HDD (can't found the data anymore)

  • Hi,


    I was doing some test on the transfer speed on my HDDs and the ones i was testing seems to have lost their mapping with their labels, that's really weird i hope i didnt erase them by accident...


    By running:

    Code
    blkid -o full

    I have the results:

    Code
    /dev/sdg1: LABEL="Autre" UUID="380b65e9-771c-4996-abbe-3efbe4c64981" TYPE="ext4" PARTUUID="44672ec2-e421-4871-911d-a4489debb0f5"
    /dev/sdb1: PARTUUID="fc2dc338-bce2-4760-9b90-816cd3980796"
    /dev/sdc1: PARTUUID="b6a51930-60e2-493a-a901-f9f8f0fc199a"


    and by running:

    Code
     ls -la /srv


    I have:

    Code
    drwxrwxrwx  3 root root    4096 févr. 14 14:58 dev-disk-by-label-Films
    drwxrwxrwx  3 root root    4096 févr. 14 14:58 dev-disk-by-label-Telechargement
    drwxr-xr-x  4 root root    4096 oct.  23 18:51 dev-disk-by-label-Autre


    As you can see sdb1 and sdbc1 are not mapped to their system file "Films" and "Telechargement"


    Code
    lsblk
    
    
    NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
    sdb      8:16   0  10,9T  0 disk
    └─sdb1   8:17   0  10,9T  0 part
    sdc      8:32   0   1,8T  0 disk
    └─sdc1   8:33   0   1,8T  0 part
    sdg      8:96   0   3,7T  0 disk
    └─sdg1   8:97   0   3,7T  0 part /srv/dev-disk-by-label-Autre


    How to remapp them without loosing my data (if they are still there)?


    Thank you

    Hat das Label OMV 5.x hinzugefügt.
  • I don't think it's the label it appears to be the file system look at the output on blkid you could run fsck /dev/sdb

    I already tried to fixed it without success

  • Look at the output, the superblock is corrupt, doing a search I've found this which might be helpful

    The process stopped quickly:

    Code
    dumpe2fs /dev/sdc | grep superblock
    dumpe2fs 1.45.5 (07-Jan-2020)
    dumpe2fs: Bad magic number in super-block while trying to open /dev/sdc
    Found a gpt partition table in /dev/sdc
    Couldn't find valid filesystem superblock


    Is my data lost?

  • run it again but as dumpe2fs /dev/sdc1 | grep superblock

    Code
    dumpe2fs 1.45.5 (07-Jan-2020)
    dumpe2fs: Bad magic number in super-block while trying to open /dev/sdc1
    Couldn't find valid filesystem superblock.

    Same without the gpt info
