ReadyNAS NV+ v2 Raid Sync OK, Volume expansion failed?
Hi,
I've been using a ReadyNAS NV+ v2 for a few years. Over the past few years, I had reached 3 x 4TB Seagate drives (ST4000VN000-1H4168) and 1 x 2TBWestern Digital Red (WD20EFRX) using X-RAID2 giving 9TB. Since I received a "90% capacity" alert, I decided to swap out the last 2TB for a 4TB drive.
Since the 4TB Seagate already in use is no longer made, I purchased a 4TB Seagate IronWolf (ST4000VN008-2DR166) to replace the 2TB WD Red drive. The new drive sync'd succesfully, but the front panel still showed '0.9/9.0T Free' so I suspected something wasn't right. The log reported "Volume expansion failed", followed a little while later by "Incomplete file system expansion detected. Resuming...". This was repeated a couple of times.
Can anyone help/advise what is happening and what I should try next?
Many thanks!

But the sharing protocols and their settings have not restored to their previous setting, despite backing up everything except 'Everything' and 'Data Volumes'. Thankfully I took some screen captures of some of the protocol settings pages, but I would have thought these should have been restored?
Have I done anything daft?!
I've never owned a v2, so I don't have first-hand experience on what settings it saves. I've have also expected protocol settings to be saved/restored though. FWIW, I have seen that not all settings are carried over with OS-6 NAS too, so it is good that you took the screen captures.
Anyway, nothing daft.

As a side-note, I'd love to know what settings/permissions are recommended for NFS and SMB... I'm using the ReadyNAS purely to serve all music and videos to an Nvidia Shield and my Windows PC; all on the same network.
One challenge here is that the software manual doesn't say what settings 5.3.x firmware lets you change. But I'd start with the default settings for both protocols. They will be set to allow anyone on your local network to access the NAS (which sounds like it should be ok for your environment).

Do you recall the starting size of the data volume?
I'm asking because legacy NAS do have expansion limits - one being that the volume can't expand more than 8 TiB from it's starting point. If you started with a single 2 TB or 2x2TB volume, you might have hit this limit.
Netgear documentation is incomplete when it comes to expansion limits for OS5.x, but I believe it is still limited by the 8TiB max expansion of other legacy models. Depending on what drive configuration you started with all those years ago, you may be hitting that limit. If that is the problem, the only solution is backup, factory default with the new capacity in place, and restore.
StephenB and Sandshark Thank you for the fast reply!
Ahh, the 8TB 'expansion limit' could be the issue... I wasn't aware of that! Dissapointing. But this would explain why RAIDar (and the Dashboard) both show the drive 'green'/OK, but with no extra capacity (the total useable size is unchanged since the 2TB was swapped out for the 4TB).
I now have some decisions to make... factory re-set and install from backup (a huge amount of work, but yes... I do have backups of everything, thankfully) and hope that the unit is capable of using the 4 x 4TB drives.
Or,
Bite the bullet and upgrade to a new NAS. The second option would probably take marginally less time as I could transfer from the existing ReadyNAS to the new one without having to mount all the backup drives (spread over several smaller drives).
Unless there is a neat way to switch out the drives from my existing unit to a new one?
Do the newer ReadyNAS have any similar expansion limits?
Another quick thought... I assume it would be OK to take out the new 4TB drive and replace the 2TB drive since I am not gaining any capacity? This was I have a spare 4TB for use elsewhere (or in the same unit after re-configuring).
