FOG image drive failed. What now?

@george1421 said in FOG image drive failed. What now?:
@cammykool I’d still like to see the output of the commands I asked for.
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.
Good copy. I’ll get that to you in the morning.

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.

I posted them for you!

@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? -

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

@cammykool ok lets make sure the drive is blank with
lsblkyou 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 eNow run
lsblkagain and you should seesdc1Next thing is to format it.
mkfs.ext4 /dev/sdc1Now lets connect it to a temp location
mkdir -p /mnt/nd mount /dev/sdc1 /mnt/ndThen run the df command to ensure its mounted
df -hOK now comes the moving of data
cp -R /images/* /mnt/ndSo 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/ndNow 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 0Save and exit fstab.
Then run this command
mount -a
Confirm that /dev/sdc1 is mounted withdf -hand you are done.
EDIT:I see that it already has the partition so you can skip to the format command in the sequence -
@george1421 yeah i already ran through and partitoned it for EXT through webmin.
-
@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 do I need to move images over? or will fog notice the new blank drive and just clear out what it has?
-
@cammykool Well if you do it will FOG will not even know you played with its files.
So what you are doing is copying the files from /dev/sdb1 to /dev/sdc1. Then finally mounting /dev/sdc1 in place of /dev/sdb1 (with the fstab changes). FOG only knows about /images directory and now how the OS gets there. It should work just like magic.
-
@george1421 I’d like to clear out that long list and thin the heard. Most of those entries are for hardware we dont even have anymore.
-
@george1421 or wopuld it be better to move everything over and thin it out using the FOG UI?
-
@cammykool said in FOG image drive failed. What now?:
I’d like to clear out that long list and thin the heard.
I guess two points here.
- Cull the herd after the move. Save /dev/sdb1 in case something happens to the new drive.
- FOG images are constructed of the meta data (in the fog database) and the raw files in /images. You have to delete both to clear everything out. The easiest way is via the web ui and GO INTO THE IMAGE definition and pick delete image from there. When you are in the image definition you have the ability to delete the raw data files. If you delete the image from the image list view it will only remove the metadata. This is by design.
-
I have started the drive transfer to cull the heard after. The state of the drive is showing itself though.
cp: error reading '/images/1-22RAMIED/d1p2.img': Input/output error -
@george1421 I have gotten a few more R/W errors. hopefully not enough for fog to not know they are there, and delete them.
-
Woohoo!
-
@george1421 I tried to delete some images now that its all said and done and it just keeps saying Attempting to perform actions. with a Delete and cancel button. Do i let it sit there or do i click delete again? if i do click delete again it just says “Invalid Login”
