I tried to upgrade a LaCie 5Big Network 2 today from 2TB drives to new 4TB drives. I went into it knowing it was unsupported by LaCie and that the firmware/OS was on the drives. I used the method someone reported was successful in this post: http://forum.nas-central.org/viewtopic.php?f=146&t=651#p6870
Getting 4 of the 5 new drives in with one old one and having them show up as new in the web interface worked. But it went off the rails when I turned it off and replaced the last disk and it wouldn't come back online. I swapped the old disk from slot 1 back in and it did come back up for web access. Repeated the same two swaps and got the same results. I figured there might be some priority to slot 1 boot order wise so I switched the new slot 1 disk which hadn't show up as new like the rest had to slot 2 and put the new disk from slot 2 which theoretically should have the firmware/os on it to slot 1. Still no dice. I then thought that maybe I needed to get the first disk to have the same done to it as 2-5 had so put the old disk from slot 1 in slot 1 and new disk 1 and slot 2. Now I don't remember exactly what else I tried but I had also at some point put old disk 2 back in with the new disks in slot 2, done a factory reset at one point and old disks 1 and 2 back in with 3 new disks, but basically it's no longer even getting an IP on the network. I also tried LaCie's steps for LNA recovery mode to reinstall a Network V2 Device OS and it said it found it but then at the end errored basically saying it had been unable to find a device to connect to (meaning it's previous message was wrong).
I last tried putting all 5 old drives back in in the same order they were before and it still will not get an IP. I now have it at home but when I was at the client's site with managed dell switches it's MAC wasn't being listed in the dynamic address table, let alone being issued an IP via DHCP. At home it's not showing up on my router's LAN client's table either (running DD-WRT).
I don't need to worry about data loss on the old drives, the upgrade was started with important stuff copied off, and only backup data remaining. If I can get it working with the new drives I don't care about getting it working on the old ones. I'll need it to use RAID5. If there's a reason why 4TB drives won't work on this (Seagate NAS drive on LaCie's compatability list), then I'd at least like to get it working again with the 2TB drives so it's usable.
I've read a bunch of stuff on here and forum.nas-central.org but everything seems to require that it get an IP first even the tools for installing the fvdw-sl firmware which makes sense but I need help getting it to do that. I'm in a bind here especially because this was for a client.
Please help! :please
