Beegfs v7.4.6 to v8 upgrade issue

[Tyler]

Hello,

I am testing the upgrade process from Beegfs v7.4.6 to v8 an am running into an issue off the bat when trying to execute the step  "/opt/beegfs/sbin/beegfs-mgmtd --import-from-v7=/path/to/old/management/dir" - per the document here.

I am receiving the following error:

---

Initializing database failed: v7 management data import failed: on-disk-format (format.conf): Unexpected format.conf:
# This file was auto-generated. Do not modify it!
version=5

Error: 1
---

Looking at the format.conf file in the /path/to/old/management/dir, the contents only contain:

# This file was auto-generated. Do not modify it!
version=5

Any assistance is appreciated.

The format.conf file is missing the fields:

nodeStates=XXX 

targetStates=XXX

Hi Tyler,

The import expects your BeeGFS 7 format.conf file to match this string exactly (note the newline after `targetStates=1`):

```

# This file was auto-generated. Do not modify it!
version=5

nodeStates=1
targetStates=1

```

If you have a support contract you could open a ticket and we could dive a bit into the history of this system to make sure it is safe to manually edit this file to match the required format.conf file layout. 

Otherwise at your discretion you could just edit the file to match the required file contents. The import checks the format.conf file to ensure there is nothing unexpected about the BeeGFS 7 management data, but otherwise the format.conf file has no effect on the actual import since we only support upgrading from BeeGFS 7.4.x. Since your version field is correct and you are upgrading from BeeGFS 7.4.6 I see no reason the import would not succeed, just double check the imported configuration looks as you expect before putting the system back into production.
