OS6 now works on x86 Legacy WARNING: NO NTGR SUPPORT!
Update: It is now unofficially possible using NTGR images to update legacy hardware to os6.X
See Post #3, for directions to install 6.2.1 on x86 Ultra and Pro Models. (ARM NOT SUPPORTED by this OS)
Be forewarned, this requires a SYSTEM WIPE and likely voids any warranty support from NTGR
Supported so far: pro 2/4/6, ultra 2/4/6, old pro / Pioneer Pro, 2100v2
Not Supported: NVX and 2100v1
Thanks go out to "HomeBrew Anonymous" for making this possible.
Update 2: A firmware image to downgrade back to 4.2.26 is now available. See this thread. While this downgrade should get you a working system again on the supported firmware, be forewarned this requires a SYSTEM WIPE and NetGear also does not provide support for this downgrade. If you have issues seek help on these forums.
Original Post/Gripes
I have been reading these forums since Monday's announcement and there has been a resounding "ooof" regarding the fact the Ultras and Pros are unsupported for future OS improvements.
To clear the air: it would appear Netgear will never support os6 on past hardware. I have almost come to grips with this, and at least they have been open and honest with their forward direction and aren't stringing us along. viewtopic.php?f=138&t=70131
The upside is our devices still work and are mostly stable and eventually we can upgrade to a new shell that has os6 support, but in the meantime our $500-1000 investment is unable to take advantage of modern features we all desire.
I don't think I can add a poll here at RN forums, but I would like to garner support for a 100% unsupported home brew of the os6 on Pro6 units.
If we get enough support perhaps a talented member(s) here would help release a homebrew of sorts.
The 3 main caveats are:
1. Netgear will never be held responsible/your warranty is void
2. A format is required (new FS and OS)
3. Data loss is highly possible
If you are still interested please post a reply to this thread.
mdgm and I have decided that its time to lock this thread. So please do post any new OS6 on Legacy issues on their own threads.

Might have been 80, now that you mention it... My v1 backup units are running a bit over 80%, and I don't recall exactly when I first saw the warnings.mdgm wrote: Was the threshold 70% on older products before warning about the volume getting full or was it 80%?
Possibly they reduced it a bit to account for the dynamic snapshots?StephenB wrote: (a) neither mdgm nor I work for netgear. We are users/customers just like you, so we have no vested interest in making "NTGR look better".
mdgm is paid by Netgear for consultancy work by his own admission. I'm sure you have no vested interest, but I haven't seen any defensive reflexes from you, neither. ;)
What on earth are you talking about here? All those RAID modes are available in OS6.[/quote]mangrove wrote: Why in the world of (multiple expletives) would I choose "slick, almost-working snapshots" over real redundancy? Only a crazy person would do that.
I think you need to read my argument again, as you seem to have missed my point. In different words: if I can only use 6.3TB of my 12TB disks (RAID5-array so 9TB x 0.7) for "performance reasons" or whatnot, why shouldn't I buy a competing product without the 70% "limitation" and throw the additional storage waste on a higher/faster RAID level?
As tony539 points out, It is just a notification that the disk is filling - not a limitation. You can fill it to 90% or higher if you want. You might run into problems, but folks have run into issues with ext when they exceed 90% also.mangrove wrote: In different words: if I can only use 6.3TB of my 12TB disks (RAID5-array so 9TB x 0.7) for "performance reasons" or whatnot, why shouldn't I buy a competing product without the 70% "limitation" and throw the additional storage waste on a higher/faster RAID level?
Though I think your real concern is Netgear's decision to use btrfs in OS6 instead of ext.
It was an unexpected choice. Though despite the caveats in the wiki, I'd say it seems to be working out reasonably well.
Yes, there have been some performance issues and lockups. However, there also were performance issues and lockups with various OS4 and OS5 NAS firmware releases, so that does not appear to be unique to btrfs.
And there was the recommendation to do the factory reset to improve performance. Annoying, but it was not without precedent. OS4 also reccommended a factory reset (to get 4K alignment).
AFAIK there are no cases reported here that show that bugs in btrfs itself caused data corruption or loss. Certainly I haven't seen any instance of that with my RN102. I have had my share of OS6 growing pains, but nothing that definitively points to btrfs.
The main drawbacks seem to be (a) small-block writes are slower than ext and (b) moves between shares turn into copy/delete, which is much slower.
Though I find the snapshots to be useful (unlike the older NAS), and the elimination of the xraid2 ext expansion limits is a significant plus.- I'm not being paid by NetGear at this time, but yes I have been in the past.
- Isn't it possible to move data between shares directly with BTRFS?
Each share is set up as a btrfs subvolume. That allows you to control snapshots on a share-by-share basis.Xophile wrote: Isn't it possible to move data between shares directly with BTRFS?
A direct consequence is that moving files from one share to another is done as a copy/delete - the same as moving files between two disks on a PC.- I confirm what Stephen says about 'moving' data from a share to another : it makes a copy/paste process. And it's slowness is truly irritating (even if I understand the necessity because of the different subvolume for the snapshot settings).. I end up copying to my PC through gigabit (wJBframe) and then copy back to the NAS, because it looks much faster in all cases...
- Hi all,
I just installed genie+ marketplace by mistake on a readynas po 6 running OS 6.1.6.
How can I uninstall it? (using putty with moderate Unix skills) :-)
Looks like this has to be done manually. Appreciate any help!! StephenB wrote:

Well, not exactly. You can "instantly" copy files around between subvolumes using cp --reflink, and then remove the original. So, to move a file from the Backup share to the Documents share, you could do:
# cp -a --reflink /data/Backup/file /data/Documents/
# rm /data/Backup/file
Good to know, thx. So with ssh, you can overcome that issue.Skywalker wrote: StephenB wrote:
