Fresh Install of 10.8 OS X

Post by jasonturner » Sat Feb 23, 2013 2:51 pm

I'm currently using Zevo Community Edition on a ML 10.8 Mac Mini which was upgraded from Lion.

I'm going to do a fresh install of the OS.

Do I need to export my zpools or any other data and import that once I reinstall Zevo on the clean system?

Or what is the process to migrate my RAID volume to a newly installed system?

Advice

Post by grahamperrin » Fri Mar 01, 2013 3:54 pm

Just one piece of advice. Before you erase, run the following command:

Code: Select all
ls -ln /Users


Note the numeric user ID of the person who most often uses the ZFS datasets.

After you install the OS: for the person who will most often use the ZFS datasets, have the same numeric ID.

(If there's a difference – if, for example user jason is 502 now but 501 later – then it'll be naturally difficult to work with snapshots that are associated with a particular ID.)

I should add a reason for the advice.

An option that you might expect to find, in the Info window for a removable volume, is not given for file systems mounted with ZEVO Community Edition 1.1.1:

[ ] Ignore ownership on this volume

As ownership is enforced without exception, so it's necessary to give thought to the details of owners (users) within the operating systems.

Hello, just have the same problem...I need to do a fresh reinstallation of OSX. I would like to keep my 2 pools as-is with any export/import because I don't have enough space to do this. Is it possible to connect an already existing pool on a fresh install? What are the commando's to use?

Regards,

Frédéric.

I was able to do a fresh install, create the user account, and install ZEVO. The ZFS RAID mounted fine without having to run any import commands.

If you haven't already done so: update ZEVO to 1.1.1.
