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.

Here's a question that I worry about:

* If they release a patch that does not fix the problem, what is the risk that they release a patch that is detrimental (i.e. deletes data...)

If you don't know what you're doing (which you must not by releasing patches that don't work).........

50-50 depends how much you trust netgear to release a good patch.. very easy for them to have a patch that reformats the drives...

Any news?
I just experienced this problem my self yesterday and had no idea this could happen. I will call my supplier first thing in on monday morning to talk to them about a warranty claim to be able to send it back and get my money back since this is a know issue that was built into the product from the start. I love the consumer rights in Sweden, we have all rights on our side for 3!!! years if it's proven to be a product error. :) Only thing is the 4,4Tb of data that i need to put on floppy disks while i get a new NAS. (never ever a netgear again tho).
I hope they will fix this NOW, but I guess me bringing world peace has a better chance of happening.

Can you be more specific please? I need to know if I can hold off on calling the supplier or if it will take several more months? I can live with one more week, but anything else is futile.

Resistance is futile!! In the meantime to calm you down, let me read you some poetry:

Oh freddled gruntbuggly Thy micturations are to me As plurdled gabbleblotchits on a lurgid bee.
Groop I implore thee, my foonting turlingdromes. And hooptiously drangle me with crinkly bindlewurdles,
Or I will rend thee in the gobberwarts with my blurglecruncheon, see if I don't!

I tried the patch and it sort of made things a little better, now I'm having trouble reading/writing to the NAS, it'll either write/read for 30 seconds and give me a access denied message or as soon as the copy/read process starts it hangs.

I'm really annoyed with netgear, Had problems since day one, I should be given a upgrade to the new NAS.

that was very good but could you have just thrown me out of the airlock instead?

on a side note, NETGEAR aren't quick about anything....

It might just be one man/woman handling the coding for all their products, it wouldn't surprise me at all considering the lack of progress and answers you guys have had since the first thread started.
Is it all Netgear NAS'es that has this problem or just the consumer products like the nv and nv+ v2?
