ReadyNas NV+ v2 fails to write beyond 90% capacity
I have a ReadyNAS NV+ v2 running firmware 5.37.
It contains 4x2Tb drives in an XRAID array giving a total capacity of 5.4Tb. It's connected over a wireless network.
I'm running WIndows 7 64 bit and using filezilla in passive mode to transfer files to it.
Everything was fine until recently - it's currently showing 507.6Gb free which is approx 90% full. If I try to transfer a file over FTP, it transfers about 15-18Mb and then freezes signifying connection timed out. I get the same if I try to copy using Windows Explorer. This happens with large files (1.5Gb) and smaller files (30Mb).
If I delete a file ~2Gb from the box, it doesn't make any difference, so the 90% thing is probably a red herring.
I can copy files from the device without issue.
Any idea why it is behaving like this?
Note I have a ReadyNAS Duo sitting next to it, connected to the Pc in exactly the same way and this behaves fine.

- the write performance is low when almost full, we are trying to come up with a solution.
viewtopic.php?f=21&t=63992 - Well I wouldn't really descibe half a tera-byte of free space as "almost full"!
On the other thread you cite fragmentation as a possible cause - that wouldn't stop small files from being copied over unless there was a serious issue with where it tried to locate the files - it's almost as if there's a space on the drive that is approx 15Mb in size and it writes until this is full and then gets stuck thinking about where to put the next part of the file. - 90% is almost full.
- Is there a timescale for this rather critical fix? The other thread is over 6 months old!
If not I will be returning the box as unsuitable as sold and demanding a full and immediate refund. - I have 2 Readynas NV+ and 3 Readynas NV+ v2 units all with 4x2TB drives conected via a copper gigabit network.
All 3 of the NV+ v2 units exhibit the same symptoms you have described (I have tried WinXP 32bit and Win7 32 and 64bit).
Neither of the NV+ units exhibit the limitation.
When writing through either FTP or Windows Explorer file copy, the transfer halts and any further copy attempts fail.
In addition to the failed copy, mapped network drives (in windows explorer) report as disconnected for a while before reconnecting.
Once reconnected, I am able to read fine, delete fine, but not copy more until I have deleted space from the Readynas.
When attempting to copy the files again (or different files assuming my files were the cause), when reaching approx 500GB free space the copy fails as per before.
As for fragmentation being a cause, I have factory defaulted one of my NV+ v2 units and tried to directly copy (both FTP and windows explorer copy) more than 5TB of data to the drive and the same symptoms occur. Not sure if this helps anyone diagnose the fault. - I got a message asking me to reformat it to ext-3 as a "temporary measure".
I'm currently awaiting a response to my demand to know what the time-scale is for a fix. - I have exactly the same problem, in fact 3 issue's since i've had this NAS, support isn't good either. Its been a month since I contacted them about a MKV/DLNA issue, fix was provided to them, they haven't implemented it, the issue in this thread and no support for my 3TB WD My Book USB 3
- Now the workaround is format the data volume to ext3.
- Not exactly a option when the NAS is full.
They need to sort this issue out. - Netgear are now lying to the retailer I purchased the device from.
They have told them, that there is a firmware fix, when in fact there is not. There is a workaround that degrades the capabilities of the device.
Time to start spreading the word regarding this issue.
