Hit 8Tb limit - how to expand to 18T physical?
Hi all, hoping for suggestions here for an easy(ish) fix... first let me stress that I've had experience in UNIX and I'm not stupid, but my training is out of date and to be honest I find all the tech...
You'll find that the predictions aren't that accurate. It does take a while though.
~15TB would be your final volume size with 6x3TB xraid, so you are correct in your thinking
I would have done the backup before the expansion myself, but of course that is in play already. One small modification - if you have add-ons installed you need to reinstall them before you restore the OS config. Remove any you don't need prior to the backup.
1 Upgrade drive 4 to 3Tb, making 4x3Tb + 2x2Tb (but still limited to 8Tb volume)
2 Uninstall any un-needed add-ons
3 Back up the data (plus the OS and config) over the LAN
4 Factory reset and firmware update
5 Reinstall any add-ons you had remaining after step 2
6 Restore the OS and config
7 Restore the data
8 Upgrade the final two drives from 2Tb to 3Tb
It sounds to me like you can backup and restore data with normal AFP. Then reset owners/permissions as desired after the install via the "advanced options" tab for each share. If you can locate a file utility that verifies after copying, you might want to use that. Teracopy will do that for Windows - but (being a non-mac guy) I don't know what you could use with OS X. It's reassuring to know that all your data got onto the JBOD with no problems (and equally reassuring when you restore it!).
