No space error on RN312
Having issues on my ReadyNAS 312, running latest (6.2.2) OS.
Two Seagate 3TB drives installed.
The device is serving files just fine over SMB, but MySQL has stopped working.
It reports a "No space" error when trying to start it.. which is a bit weird.
Also, df -ih reports no inodes available on rootfs... Is that normal?
Any ideas on what's going on?

Re: No space error on RN312
The rootfs uses BTRFS on the 314, so that inode check is not relevant.
What is the output of
What is the output of
# btrfs fi df /

Re: No space error on RN312
The error is odd as there is plenty of free space. Do you get the same error starting other services? Do you still get the error after a reboot?

Re: No space error on RN312
Problem persists after reboot, and it's only MySQL causing it.
Yeah it's a bit weird...
I've started the process of moving all data to a couple of large USB drives, will then reinstall the NAS from scratch to get a clean setup.
Probably overkill, but it's usually a good idea to do that kind of cleaning every few years.
On that note: What does the "factory reset" in the web UI do, exactly?
I guess it just clears all config parameters? Or does it trigger a proper re-install of the OS (which is really what I'd like!)?
Edit: Found this: http://kb.netgear.com/app/answers/detail/a_id/20898
Which is at least a starter for the OS reinstall procedure

Re: No space error on RN312
A factory reset will trigger a wipe of your disks and a clean install of the OS. All data, settings, everything is wiped. It will use the firmware currently on the internal flash (in your case this would be 6.2.2). When you update the firmware, you are prompted to reboot the NAS and the firmware is updated on the internal flash and then on the disks.
An OS Re-install installs the OS over the top of itself and resets the admin password and some network settings but leaves your data intact. It doesn't sound like your issue is one that an OS Re-install would be likely to address.
Could you please:
1. Backup your data
2. Once you've verified you've backed it all up try starting MySQL again, then download your logs and send them to me (see the Sending Logs link in my sig).

Re: No space error on RN312
Ok I understand the distinction between firmware and OS, I still would like to start over with a fresh OS though, as I have been messing around a bit more than probably good with the OS. Nothing serious, but installing a few different software packages that I later realised I don't need, etc.
These eat up space, and even though they can be uninstalled, it's time for a house cleaning, I think.
So given that I have 6.2.2 installed already, what steps are needed to return the NAS to factory state?
I.e. if I would like to wipe current OS install and replace it with a fresh one - not just installing the OS again on top of the existing one (sounds like that could leave some issues for the new OS, if unlucky).
Or is the OS re-install wiping the old OS entirely first, before installing?
I have both online/remote backup of all data, as well as local USB drives. Should be safe.
Will try to start mysql again and send logs before doing the OS re-install, though.

Re: No space error on RN312
Factory Reset is what you want. That will wipe the disks and return the NAS to how it was from the factory except using 6.2.2 (the firmware currently on the internal flash) rather than the one that was on the unit when it left the factory. Some improvements can only be obtained by doing a factory reset on new firmware. These benefits are not essential, but can be nice to have.
An OS re-install will try to fix things leaving the data intact and only resetting settings that may lock you out of access to the NAS if configured incorrectly.
Of course if you want you can try the OS Re-install and if it doesn't fix your issue then do the factory reset.
Please note a factory reset will wipe all your data.

Re: No space error on RN312
Got it - thanks for a crystal clear explanation.
rsyncing the data over to external USB drives takes a couple of days, so I'll let that finish before I proceed.
Many thanks for the help, and all the best for the new year!
