i've recently purchased one of the Netgear ReadyNAS NV+ V2 units and have become very unhappy with it. it started out ok and could copy files to it at good rate, now that the unit is over 80% full i've been coming accross the smbd stall on IO Wait issue that seems to plague this unit :(after coming to these fourms i found that there are many other users with the same issues and none of the solutions they have had for them posted around converting to EXT3 has made the copy issues any better for me.i have linked the other topics i could find with same issues that have been plagueing me so far. i have logged a support case (20047616) with netgear but their "remote access policy" is very bad and i can't agree to it. viewtopic.php?f=21&t=63992 viewtopic.php?f=21&t=64739 viewtopic.php?f=21&t=67310 viewtopic.php?f=21&t=66731

Converting to EXT3 helps, does it? And what do you do if you already have all your disks in EXT3???!!!Netgear have never impressed me on quality nor performance, but the Sw engineering quality control really hits the bottom. Have they ever heard of version control? Have in gods name can an old bug pass through to a subsequent release - albeit a Beta???!!!This was the final blow for me- getting in to my car to go and by a Synology or Qnap - whatever bet never again Netgear and Readynas!

Converting to EXT3 will help. Again thank you NETGEAR for quality control.You need to download your data because it will be wiped (from what I've been told). Yes, you need to give them root OR add drives to get below 80%.. I did both ...

I'm looking into this issue, from the logs I see that you converted to ext3 yourself, and you're still running into the issue, right? I'm chasing down a few things, could you confirm, are you storing a large amount of small files on the device (checked volume stat, if my math is correct, average of 3.5MB per file)?Are you only using CIFS/SMB to copy files to the NAS?

This problem is related only to filesystem itself not to anything else.This is propably kernel bug, somewhere at journaling code. I found it on Synology and QNAP forums and people are very angry because of this.There's nothing in logs only IOWaits raises to 100% after any write is performed and system is not responsive for some seconds/speed drops to 10MB/s or lower.Maybe disabling journaling in ext4 can help, but I don't trust this filesystem for now.I saw this problem when volume is aprox. 85% full and I have a lot small files on it.When you format ext3 volume you can switch to ext4 driver and in that situation everything goes wrong.Journal must be recreated while you are going back to ext3 - if not, ext3 have same problems as ext4 (100% IOWaits).Perfomace with nearly full volume on ext3 is ~50MB/s write ~80MB/s read - not bad for ARM platform.

it was a waste of time for myself, the best resolution i've had to the 80% issue was to get a refund for my unit and get one by another vendor that doesn't have this issue and doesn't consume any space on the storage volume when freshly formatted.

performance has also been better for me with the exact same disks in the other unit, netgear i could get at most 50% utilisation over a gig network card, now im getting 90-95% utilisation of the same gig network card.

Unfortunately, by the time I realised there was a problem, it was too late to send it back :(

What did you replace it with? To be honest, I've totally lost confidence with Netgear and their quality has gone downhill in recent years. Next NAS I buy probably won't have their badge on it.

depending on your country it may not be to late, here in Australia i had at least 12mo to be able to return it under our laws. currently i've got the HP N54L, i had to install the OS myself but that wasn't hard and the unit was actually cheaper than the netgear unit.

the OS i've chosen to use is: http://openmediavault.org/ it has a simpler GUI to manage the hardware but you have complete control over how things are setup an ran. and it's got plugins/add-ons that allow you to extend the base features even further.

So my issue returned despite all the promises and firmware patches. I now get to 300GBs and then the unit crashes and has to have he power cut and started up again before it can be used. I cant even be bothered to raise it with Netgear again, they have already absorbed more hours of my life than I would care to give to a product that should have worked to begin with. I will never be buying Netgear again. I guess the appeal is their cheap products and the way that that massively undercut the competition. I would be happy to pay more for something that worked.

Robclarke41, what version of firmware are you using now?
