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.

I use Microsofts iSCSI initiator on 32-bit win7, and the very same iSCSI partition gets 40 MB/s in writes just formatted as NTFS. So TrueCrypt means 1/10 write speed. Read speeds are the same. Machine speed is not an issue here.- No ideas off-hand. Is there an option to choose a larger block size on the client side?
- Hmmm this indeed looks like a problem with small blocks, XTS and MDRAID... NTGR's off the hook... for now. ;) Tried upping stripe_cache_size but that didn't help at all.
BTW, was there ever talks (or even performance comparisons) of replacing the file-based iSCSI container with a device-based one? - It's been discussed. But you just lose so much flexibility (space must be pre-allocated at volume creation time, deletion immediately frees up space on the main volume) and features (snapshots, compression when using thin provisioning) that it was considered to be more trouble than it was worth. The performance gain in our testing was not significant. But I'm certain there are certain workloads where it would be beneficial.
- How do you solve the performance problem with your own encryption? Larger blocksize?
Where in the process does the decryption take place, and are there possibilities other than USB keys to unlock the volume? Specifically, how much of the OS boots before decrypting the volume? - Has anyone attempted to add a signed SSL certificate to OS6? I've been browsing through configuration files, but haven't really had much luck finding where the certificate is added.
- Can someone summarise the pros and cons of upgrading a pro to OS 6.
Are there any speed benefits or specific enhancements that make it worthwhile?
If you do so is it fairly easy to drop back?
thanks - I'll let someone else summarise the differences but you can easily go back (though you do have to backup your data before downgrading as a factory default is required). I'll send you a PM with instructions on how to downgrade.
- Something I noticed on my Ultra 6.. I't not using swap at all. The swap is always at 2094844 total, 0 used, while physical memory is pretty much always at 1009592 total, ~22000 free. Did I break something by chance? Could this be the cause of very slow copy actions? Load is currently at 11 for a simple par2 action, while under OS4 I never saw those numbers.. now the default load seems to be 3 instead of the ~0.7 I was used to.
- If you were using swap that would be an indication that you don't have enough memory installed. Not using swap is a good thing. I assume a fair bit of your memory is currently being used for caching (this is good for performance and memory is freed up when needed)?
