a few items from my wish list....

2- There is indeed an 8Tb expansion limit for old models. I believe this is an addressing problem and I am not sure this could be addressed by doing an offline expansion. I am not specialist of the question though.

The 16 TB volume size limitation is an addressing problem (32 bit vs 64 bit inodes). OS4 will automatically format using 64 bit inodes in some cases, but not all. One consequence is that some disk configurations cannot be used even with a factory reset. 1x3TB+5x4TB is one of several examples that fails. The simplest solution would be to always use 64 bit inodes, but that would increase filesystem overhead.

The 8 TB growth limit is not addressing, and off-line expansion can be used to overcome it. https://www.readynas.com/forum/viewtopi ... 6&p=356612 Netgear does not recommend this method, and I believe there are at least some users who found it failed in their case.

I don't expect to see either of these expansion issues addressed in OS4, though Netgear has surprised me before :)

3- There is a way to change linux permissions with OS6, the file access tab on the settings for a share gives you some possibilities.

I agree with alexofindy that the OS6 GUI is inadequate here. OS4 lets you change all file permissions and owners within a share to values you can set. OS6 "reset" is closest to that feature, but the owner/group and permissions are not settable. At present the only way to overcome this is to use ssh.
