Need simple guide for replacing system disk after failure

Hello All,

Been using OMV 4 for several years and very happy with it. Have upgraded/replaced RAID disks a couple of times without problems.

Today my system boot disk died. I replaced the system boot drive and installed OMV 5.5.11 instead of the old OMV 4. The OMV web interface of 5.5.11 shows my storage disks and RAID are intact.

Is there a simple guide for replacing a system disk? Re-adding shares and users without overwriting any data? Also, all of my users had a private folder, which I do not want to overwrite either. I did not install nor use any additional plugins on OMV 4.

I've ddg'ed and googled for replacing an OMV system disk but cannot find any guides (nor on this OMV forum). Maybe I'm searching for the wrong terms...e.g. "OMV replacing system disk/drive".

I'm a competent linux user but not confident in the OMV envvironment.

Ok, super thanks! OMV is great!

The group shares are back up.

The home directories under the PersonalFolders are not working.

I'm problably just doing something out of order but here is what I've done.

1. Access Rights Management --> Shared Folders --> Add -->

Device = Data

Path = /PersonalFolders

2. Access Rights Management --> User --> Settings --> User home directory -->

Enable = toggle switch "on"

Location = PersonalFolders [on Data, PersonalFolders]

3. Access Rights Management --> User --> +Add -->

Name = [I added a previous username and the same password as before]

4. Services --> SMB/CIFS --> Settings --> Home Directories -->

Enable = toggle switch "on" for Enable user home directories

Save and Apply changes

Using that username and password in step 3 above I am not able to acces the previous home directory for that user. That user can access the group shares.

What am I missing?

Thanks all...

I've performed some more experiments with weird, indeed security breech-like results.

There were originally 6 users on the system.

Let's call them user1, user2, ... user6.

I recreated user1 with the same password as before, but now using the new system boot disk (going from omv4 to omv5) user1 cannot access their own personalfolder but they can access the user6 personalfolder with full read-write privileges. Does that mean the UIDs are messed up then? How on earth would I set them straight, yikes?

Additionally...

Before on OMV4 the PersonalFolders share did not "exist" per se, and the only way to connect to a users private folder was to provide Windows Explorer or Samba on Linux with the username and password. Now, on OMV5 the PersonalFolders share is showing up like all the rest of the regular/normal shares. However, as stated in the previous post, the wrong users have access to the wrong personal folders.

Okeedokee...

Did some more experimentation and got the following results...

new username on OMV5 = (grants access to) old username on OMV4

new user 1 = old user 8
new user 2 = old user 2
new user 3 = old user 4
new user 4 = old user 3
new user 5 = no old user access
new user 6 = old user 5
new user 7 = old user 1
new user 8 = old user 7

Soooo, I'm no expert here but this looks like the new and old UIDs are not matching up maybe?

Does anyone know of a **SAFE** way to change UIDs so as to NOT lose any data?
