Migrating 6/f14 to 7/f19 - Advice on order of doing things

[frodemann]

Hi,

I had 3x2TB pooled disks in Amahi6. Two of them reported lots of bad sectors, so i took them out using the "greyhole-going" command.

I now have Amahi7 up and running on new harware. On my desk i have the surviving disk from Amahi6, and two new disks.

From reading the wiki and forum I think I understand what needs to be done is:

- install Greyhole
- recreate exactly the shares from Amahi6
- install / mount the surviving disk
- install / mount the new disks
- add old disk to pool
- add new disks to pool

1. What order should i do these steps?
2. Am I missing something?

Thanks

F

That sounds about right. The wiki guidance should be fairly accurate.
https://wiki.amahi.org/index.php/Fedora ... _migration

Although this is for Fedora to Ubuntu, it is relevant.

Here's another one that is good.
https://wiki.amahi.org/index.php/Reconn ... orage_pool

Thanks, I have read those links now but, since Greyhole must be installed manually, i cant figure out wether to install the greyhole software, or put the disks in first? Or, maby it doesn't matter?

Edit: Now reading your ansver again, I realise perhaps you ment the order i listed the steps seemed reasonable?

Cheers

Is this considered resolved? Please let us know how it goes.

[frodemann]

No, not resolved due to other parts of life keeps me from spending time on computers these days. This might take some time, but please bear with me, i promise to report back.

Greyhole now up and running. Data from the old disk restored.

I chose to install / initiate the two fresh WD 2TB Red disks first. Then install greyhole and get it to run properly before introducing the old disk with data from Amahi6.

Got a little frustrated at first when i tried to run a fsck and nothing happened. I then tried:

Code: Select all

greyhole --fsck --find-orphaned-files

witch got things back in business.

[bigfoot65]

Good to hear it's all working good now.

... or maby not

Maby this should have been a new topic in another forum. Just say so if i should move it.

After starting to copy all my photos back on to greyhole, the greyhole daemon is constantly working an the hda goes down from time to time.

tail /var/log/greyhole.log:

Using LogAnalyzer i found the last three entries in the greyhole syslog before the server went down

I have moved the landinzone to "/home". Is that a problem? (Was the partition with most free space after automatic install)

Edit:
I'll make a new post following this: "https://wiki.amahi.org/index.php/Greyho ... leshooting" if the above is not enough to resolve the problem ...

Need to look more into it, but I now suspect Microsoft SyncToy and Greyhole together caused the trouble.

[bigfoot65]

Try FreeFileSync. That's what I use and have no issues. There's a portable version too.
