How to resize / remove the snapshot reserved space ?

Hi there,

I've got a question about the snapshot space on ReadyNAS Pro.

I saw on this topic (viewtopic.php?f=66&t=35266) that since 4.2.7 firmware, the "resize snapshot" option has disapeared from the frontview. Unfortunately my RNDP is in 4.2.9 Smiley Sad

But ... (because there is a but Smiley Tongue) I got an ssh access to my NAS, and I found a script called "resize_snapshot" into /frontview/bin directory. This script seems to be used to manage the snapshot volume space (increase it or reduce it).

My question is simple, can anyone of you tell me how to use this script ? Is it as simple as "/frontview/bin/resize_snapshot <arg>" where <arg> is the volume space desired in % ??

I read that space cannot be set under 1% of total volume space (viewtopic.php?p=54465#p54465) when the operation is made from the frontview.. Is there a chance here that we can set the size to 0% ??

Thanks for your help !

Do you have a Pro Business Edition or Pro Pioneer?

I think the advice I've read elsewhere on the forum for your issue is to either backup all your data and factory default or wait for the re-enabling of snapshot resizing in a future version of the RAIDiator x86 firmware

OK thanks!

I'll wait till this option is re-enabled unless one of the readynas master give me the right syntax of the script command Smiley Happy

Re: How to resize / remove the snapshot reserved space ?

I would like to add to this....I also have a ReadyNas Pro and I am running 4.2.9....Well I am adding disks to the original 3 disk config and EVERYTHING is being allocated to the snapshot! I now have more snapshot space than I have online storage space and I still have one more disk to add. WTHeck?????

This needs to be fixed ASAP or this system is useless. I need drive space, not snapshot space!

Knothaid:

Have you try this?

Step(s):
1. Make sure disk spindown feature is disable.
2. Make sure "Disable Journaling" Feature in System->Performance tab is uncheck.
3. Reboot the unit. You might needs to reboot twice.. but make sure you give 5-10mintues between each reboot.

Yes, in fact, it would not grow the volume until those things were done. I now have 1.9T of Snapshot space and 1.7T of storage space and one spare drive. All disks are exactly the same model Seagates.

Edit> Of course it would only grow one disk at a time and it took a reboot each time to make it happen. It reported one disk had data on it and I needed to either remove for 10 seconds and reinsert or reboot. There was no data on it that I could tell, it was new out of the package same as the other two. Each disk took about 48 hours to resize the volume.

You can contact technical support (see link in my sig) for help if you like. Post your case number in this thread.

Re: How to resize / remove the snapshot reserved space ?

I find the relay to support kinda confusing. You are asking me to go pay for them to fix something that was not broke until they "fixed" it. Yet here we have a support forum for just such answers and many time you direct folks away...So perhaps there is no point to the forums????
