ReadyNAS 214 volume is set to Read Only, please help.
My ReadyNAS 214 suddenly set to Read Only, And when I go to the logs, it just said "Volume: The volume data encountered an error and was made read-only. It is recommended to backup your data." I h...
Hi,
Funny enough I have the same problem....
It started around september 3.
After fooling around with my TimeMachine space in the evening, the next morning I got the 'volume data01 encountered an error and was made readonly.' error next morning.
The system also triggered a daily message that a USB device was connected. This normally doesn't happen, but since then it does everyday (like a service is started everyday).
I looked through the disklogs but didn't find any error's. Nothing on the disks either.
Making data backups was/ is not possible, because the system has to wright something to a readonly disk... 🙂
A reboot made no difference and a reinstall of the OS either.
I also performed a extensive disk test from the boot-menu.
Now, I am not eager to do a complete new setup and restore, since the system does not make a backup of the system itself (which I always found strange....) and it needs lots of manual configuration (like folders and so on).
But if that's what it takes, I will bite the bullet 🙂
I can share my logs if that is any help.
The system is a RN214 with 4 x 3TB - Seagate ST3000VN007
OS: 6.10.8
PS. I just looked at the system and kernel logs and they are filled with error's.... It doesn't mean anything to me, but perhaps it gives a clue to an expert 🙂
Thx!

Not the case. You can back up the data from a read-only volume. That can either be done from ReadyNAS backup jobs, or by copying the files with other tools (one of several examples is freefilesync running on a PC). The backup job config files are in the OS partition (not on the data volume), and that should still be writable.
Your data is definitely at risk, so backing up the data ASAP is really important. Rebooting the NAS often results in the volume not mounting at all. Even if you are really careful not to shut it down or reboot, all it takes is a power glitch to force a reboot. Also, a corrupted file system can trigger a crash.

I am willing to take a look. Put the full zip in cloud storage (dropbox, etc), and send me a private message (PM) with a download link. Send the PM using the envelope icon in the upper right of the forum page. Make sure the permissions are set so anyone with the link can download.
In most cases I will recommend a factory reset, as this is the best way to make sure you have a fully clean file system.
Hi StephenB,
Thx for replying so quickly.
I made a copy of the changed files to a Folder on my Mac, so that together with my backups will do.
But the Backup tool on the ReadyNAS is not working... The Backup tool does not see my attached USB backup drive. The external drive does show up as a volume, but does not show up in the tool.
I will put a link to the log-zip in a message.
I am pretty sure what the recommendation will be, but I can always hope 🙂
I am just curious on what the issue is.
Jackvd It seems I have exactly the same problem as you. I also do some TimeMachine space updating or deleting. After that, the data volumn is locked.
If you could fix the problem instead of restoring the NAS, please let me know.
StephenB did look at my logs, but he couldn't find the root cause because the data didn't go back far enough.
That was probably my fault since I did perform a reinstall of the OS from the Bootmenu.
The other thing that didn't help is that my volume is encrypted and StephenB explained to me that he never had a setup like that.
Anyway; the logs showed massive checksum errors while writing so somehow the OS had a hick-up.
So I did a factory reset and reinstalled the complete system....
I did it before a couple of years ago after two of my disks got corrupt in my Raid5 setup 😞
I have backups of all my data and the system restored 2.7TB up until now. Probably another two days for it to complete.
Maybe your issue is different and if you have the complete logs, StephenB can have a look at them.
If you have to do a factory reset, make sure you follow the right sequence. There are instructions in the community that you can follow.
Sorry I couldn't help and good luck!
PS. it is weird though, that your problem sounds just like mine.....
