Please Help, 5Big Network 2 upgrade attempt gone wrong

Indeed, you need to do it as you reset fully the disks.

and you need to do it with the real sda device.

Finished the process with the following:

Then it was back online and back into the web interface! While online I inserted the other 4 4TB drives and it after some processing recognized them all as "New". I then configured a RAID5 array and it stated that it would result in 16TB of space during the setup but after the setup that's not at all what it's presenting.

I had not ensured the other drives were erased or that their partitions were removed before reinserting them as I figured it would wipe whatever information when it detected and configured them... I'm guessing now that was a bad idea, but I'm not sure if I should wipe them now? Break the raid first in the working web interface?

I did try formatting it from within the web interface but that didn't change anything.

As you don't have data,to use the web interface to break and rebuild the raid may be a good choice.

I reconfigured it from 5 disk RAID5 to 1 disk basic. Then tried to go back to 5 disk RAID5. The LaCie seemed to have a method for doing this "without data loss" it showed but the process failed through it's multiple steps (2 disk RAID1, 2 disk RAID5, 5 disk RAID5 it showed). I then tried the 5 disk RAID5 process again which was successful but I'm left with the same small space again.

With the 1 disk basic configuration it did show the full 3.6TB available of the 4TB drive.

Hi hvymetal,

maybe use fvdw-sl console and try to assemble the raids can be useful to understand what is the issue.

And I reread your topic and I don't understand you why you did not reset the other disks as you wrote:

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.

And I reread your topic and I don't understand you why you did not reset the other disks

By reset do you mean just repeat the full process with each one in slot 1 (far left) in turn or just the initial part of removing any existing partition table?

I'm wondering at this point if I should redo the first drive just to make sure the content on the others didn't change it at all.

[Jocko]

What I meant it was to repeat the process for each disk in slot1.

But why did you not try to do a factory reset directly with your new disks ?

[hvymetal86]

Well I erased the partition tables on the 4 additional drives in turn, then recreated the RAID 5 and it still showed the wrong capacity. I then attempt the factory reset with data loss method like you linked and it appeared to work from the indicator lights LaCie's article describes, but then the system wouldn't load the web interface anymore. I then tried LaCie's OS re-install but after it stated it found the device and was re-installing it ended saying it actually couldn't find the device.

I'm now going to repeat the steps that got them working OS with all 5 drives. If that doesn't get it to where it can make a RAID with the proper size I'm guessing my options are:

1. Manually examine the RAID configuration via standalone kernel and attempt to fix from there
2. Try the restore process with all 5 2TB drives to see if the size issue stems from 4TB vs 2TB
3. Attempt to load the fvdw firmware/os on all 5 4TB drives

[Jocko]

Sorry to read this.

Just an idea :
For some manufacturers, the disks have a slightly larger size, for example 4.1TB to 4TB and maybe 5 big2 can not handle fs bigger than 16TB (usual limit). So check the real size of your disk and calculate the raid size with the partitions 2.

(raid5 size with 5 partitions = 0.8*partition size)

[hvymetal86]

Well now I'm confused. I ran through the same steps I did before get it working and it won't get into the web interface. It gets an IP meaning DHCP must be working but the front light flashes blue continually. Going through it all again now. I intended to test each disk one by one as I reset them.
