@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?
-

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”
-
@cammykool It almost sounds like the permissions on /images and below is now allowing the files to be deleted. The service account fogproject is used to remove the files. If they are owned by root and have the standard permissions of 755 then that would keep the service account from deleting the files. You could change the permission to 777 for the image directories then the ui should be able to delete them. Understand the goal is getting the job done and not security at this point.
-
@george1421 do i just run sudo chmod 777 imagefolder

Just tried pushing my first image. File copy went off perfectly It is hung on Updating Database Another permissions issue?

@cammykool Try rerunning the fog installer script that may fix the permissions on the /images directory. If not, while this is terrible for security you could run
chmod -r 777 /imagesThat will set everything in images to read/write. But see if the installer script fixes the perms first. -

@george1421 doing that changed the error I was getting when uploading and it trying to update the database but it didn’t fix it I’m getting a new error now.
