Amahi Forums

Hi,

I added a 3TB hard drive to my new Amahi 10 server. It had about 2TB of files on it. I added it using the Disk Wizard, and didn't format it but just gave it a label. I think I chose the ext4 option. But I don't see any files on the disk when I use the ls command in a ssh terminal. I tried adding a share to the disk and it created the sharename folder, but no files visible. When looking at the Add page of the Disk Wizard, I can still see 2TB in use.
I am not sure now what file system the disk was formatted with, although it was part of my old Amahi 9 server. I think I may have formatted it with NTFS, would that give the symptoms I described? If so, what should I do? Is it safe to unmount it, then mount it as an NTFS disk using the Disk Wizard?

I would like to be able to get at the data. I have a backup, but to restore from that would mean trashing my new server and reinstalling Windows on it, a long process.

Thanks for your help,
Steve

Unmount the drive first.

You need to determine the file system for the drive. Then try mounting it using the correct file system based on the output.

Hi, I don't think it's mounted. When I do umount /dev/sde or /dev/sde1 it tells me it's not mounted.

Here's the output from your command:

• [steve@localhost ~]$ sudo df -Th

  tmpfs tmpfs 196M 0 196M 0% /run/user/1000

As you can see, sde isn't there, neither is sdb, sdc, or sdd. I'm using greyhole, but the disk I can't view is sde, which isn't in the pool.
Thanks

OK, so I rebooted, and the drives seemed to be mounted this time.

Here's the output. I unmounted it and then ran df -Th, but it didn't show me what filesystem it was.

You have to unmount the drive at it's mount point: Then try running the command to see if it identifies the file system.

BTW all commands when dealing with drive mounting and unmounting have to be done with elevated privileges.

Hi,

So I shut my new server down, took the drive out and put it back into my old server and booted that up. It WAS ext4, not ntfs or anything else, and it turns out that the problem was the share name. In my old server it had been shared out of location:
/var/hda/files/drives/drive1/wsse1copy
On the new server I decided to use:
/var/hda/files/drives/HDD4/WSSE1Copy
But that didn't work, because Linux is case sensitive and WSSE1Copy is completely different to wsse1copy.
So I used:
/var/hda/files/drives/HDD4/wsse1copy as the share location.

Now I can see all of my data!

Thank you for your help, it's very much appreciated.

Steve

Glad you sorted it out.

Marking this one solved.
