Welp! Help!

[modem7]

Hey guys,

I was trying to replace a hard drive (1tb for a 2tb), and followed the instructions here:

So I did:

sudo greyhole --going=/var/hda/files/drives/gh

and Greyhole started copying files over. All good so far.

Tried
sudo greyhole --gone=/var/hda/files/drives/gh
But it said it didn't exist anymore

Removed the drive, unticked it from the dashboard, edited the fstab in accordance to the Wiki, and things have kinda gone pete tong.....

Halp?

[bigfoot65]

I presume you specific which drive as being gone since your post does not indicate. Did you umount the drive before removing it? Also did you ensure Greyhole was done?

Not sure what happened, but might want to ensure the structure to mount the drives still exists in /var/hda/files/drives.

[modem7]

Right - mild(?!) panic over - I put the old drive back in and everything is working again.

Now to do it properly.....

It seems that the drive I wish to move, is mounted at var/hda/files/drives

How would I go about doing this without breaking things?

/dev/sdd1 is the chap I want to get rid of.

Would it be best if I changed the mount point of SDD first?

Thank you!

Yes you don't want to remove /var/hda/files/drives/ That is actually a bad choice for a mount point. That's where all the mount points live and breath.

Should always be a folder inside drives that you point your Greyhole drives to. You will need to carefully rework all this to keep from breaking anything. I would recommend you copy the drives folder to your OS drive, into a share.

Then once you unmount this one, move the drives folder back into /var/hda/files directory. When you mount the drives, they others should return. Then make the new drive a different folder inside the drives folder.

Does that make sense?

This is what I feared. Unsure how it was mounted there in the first place to be honest....

However, won't everything in the drives folder include everything in the greyhole system? All 7tb's worth (granted, I can half that by killing the replication, but still going to be 3-4tb or so)

[bigfoot65]

No you need to unmount each one first. Then all that would be left is drives is folders. Copy it to a share after that.

Ah! I THINK I understand it now

[modem7]

Just to clarify (aka, I'm bricking myself! Sorry for being a noob here):

I run the following first:

umount /var/hda/files/drives/drive7
umount /var/hda/files/drives/drive2
umount /var/hda/files/drives/drive4
umount /var/hda/files/drives/drive3

(can't run umount /var/hda/files/drives/ as it's busy (umount: /var/hda/files/drives: device is busy.) and it's obviously what we want to copy).

I then copy the /var/hda/files/drives folder into a share on /var/hda/files (or can I just copy it to /usr)?

Then I unmount SDD, follow the standard process of removing it, then move back the files from /usr?

[bigfoot65]

Yes that sounds about right. You can put the drives folder anywhere as long as it's put back in the right place when you are done.

You may need to comment out the drives in /etc/fstab as well. Then when you have the drives folder back in place, uncomment them. Might have to reboot to get the SSD to umount.
