FOG image drive failed. What now?


  • @george1421 do I need to move images over? or will fog notice the new blank drive and just clear out what it has?

  • Moderator

    @cammykool Ok I updated the instructions to use ext4. It looks like you just need to mount that sdc1 partition to a temp folder and copy your files over, then update fstab/mount the drive and you are done.


  • @george1421 yeah i already ran through and partitoned it for EXT through webmin.

    @cammykool ok lets make sure the drive is blank with lsblk you should just see /dev/sdc with no partition. Make sure its the size you think it should be so you have the right drive. The next steps will be destructive if you pick the wrong drive.

    Assuming /dev/sdc Do these commands as root to su to root (sudo su -)

    fdisk /dev/sdc
    
    # Print out existing partition table, should be blank
    p
    n
    1
    p
    {pick all defaults until you get back to command prompt}
    
    # display partition table
    p
    
    # if good then write it
    w
    
    #exit out
    e
    

    Now run lsblk again and you should see sdc1

    Next thing is to format it.
    mkfs.ext4 /dev/sdc1

    Now lets connect it to a temp location

    mkdir -p /mnt/nd
    mount /dev/sdc1 /mnt/nd
    

    Then run the df command to ensure its mounted
    df -h

    OK now comes the moving of data
    cp -R /images/* /mnt/nd

    So when that is done copying over you will have your original data on /dev/sdb1 (faulty drive) and on /dev/sdc1.

    The last bit is drop the currently mounted drives and update the fstab.

    umount /images
    umount /mnt/nd
    

    Now you need to update the fstab. You need to remove the line that references /dev/sdb1 (note could be by uuid so you need to pick the right drive)

    Then add in this line

    /dev/sdc1 /images ext4 defaults 0 0
    

    Save and exit fstab.

    Then run this command mount -a
    Confirm that /dev/sdc1 is mounted with df -h

    and you are done.

    EDIT: I see that it already has the partition so you can skip to the format command in the sequence

  • Sorry for the delay. Shipping was a nightmare on that drive. A 4TB bad drive is now on sdc

    @cammykool Ok when you get it in replace /dev/sdc with the 6TiB drive then run the lsblk command again. I will give you a step by step instructions to get it setup.


  • @george1421 said in FOG image drive failed. What now?:

    @cammykool OK good deal,

    The lsblk tells us you have 3 hard drives installed at the moment

    sda      8:0    0 119.2G  0 disk
    └─sda1   8:1    0 119.2G  0 part /
    sdb      8:16   0 931.5G  0 disk
    └─sdb1   8:17   0 931.5G  0 part /images
    sdc      8:32   0 931.5G  0 disk
    └─sdc1   8:33   0 931.5G  0 part
    

    /dev/sdb seems to be currently mounted on /images

    I take it that /dev/sdc is the new disk that already has a partition on it?
    Did you just create that partition or is it residue from another install?

    dev/sdc is a spare drive i had in there its even older then the drive i currently have set up for images and was in a computer running a ticker display. I don’t trust that drive at all but its in there just in case. The new drive should be here today its a 6tb surveillance drive

    On the surface replacing that drive is going to be a trivial task. It will take you longer to physically replace the drive than it will be to integrate that into FOG.

    I posted them for you!

    I don’t really care about the images. I have them set up now so they can be consolidated into just 3 or 4 images total not this huge list. so I don’t mind starting over as i have a machine ready to push new copies of images to the new drive.

    Good copy. I’ll get that to you in the morning.

  • @george1421 said in FOG image drive failed. What now?:

    @cammykool Its still not clear how you have the FOG server setup. I can read what you posted two different ways.

    Is your FOG OS installed on the 1TiB drive, or is it installed on a different disk? If the fog images and the FOG host system is on different disks then the update/replacement is pretty easy.

    Lets start out with having you run these commands and posting the output.

    1. lsblk
    2. cat /etc/fstab
    3. ls -la /images

    Lets see how you have the system currently setup.

    My apologies, the fog server is on an SSD and there’s a separate drive for storing the images. The drive starting the images have failed but the fog SSD is fine
