BTRFS read-only state, OS 6.8.10, ReadyNAS Ultra 4
Hello, everybody! It seems like I have met the same problem as a few other people here, namely BTRFS becoming read-only. Background Machine is Ultra 4, with 2GB memory, converted to run OS6. Capac...
Hello, Sandshark! THANKS for the answer. 🙂
I noticed that while I was writing Stephen B also answered with some more information. Thanks, Stephen, I will read and see what I can understand of it.
OK, I get it. 🙂 I was probably a bit too impatient with the power off. Well, you never cease learning; I thought - correct or wrong - that a NAS would and should survive an unexpected power off. I was wrong and stand corrected. Guilty as charged.
The curious and "funny" thing is that it seems like I cannot even do "ls" on my /data directory (I/O error), but I can access /data/Pictures without problems, while /data/Videos gives me I/O error. Nevertheless, I have full backups of stuff.
As far as installed applications go, it is not a problem either, as I have downloaded the binaries long time ago and actually only use ssh and possibly MySQL with PHP.
I am adding to this discussion because I am looking for an answer to the exact same question.
My ReadyNas 516 accidentally filled up to the max (due to an emergency backup of another drive) and threw an error because of No Space Left. The Log reflects this to be the only case and there is NO hardware issue, which has been confirmed. SO there is NO backup needed of the system, which I already have (mirrored NAS).
I just need to be able to delete files again.
The system however keeps switching to ReadOnly mode when I reboot due to lack of space, and due to ReadOnly mode I cannot create more space by deleting files...
So, with all the hardware being just fine, how do I tell the system to let me erase files so I can create more space?
I am SSH inept, but I can follow instructions if I have to.
I can enter SSH via Putty and I find myself at the prompt:
What can I do next?
tijgert , I answered your question in the other thread where you posted it. Note that it's best to open a new thread so different advice to two users doesn't get confused and posting the same query is certainly unnecessary.
Got it.
I was trying to avoid asking a similar question in a new thread.
Doing that twice actually created the clutter I was trying to avoid...
I'll ghost this thread and kindly request anyone to forward any replies to the other thread.

But when it turns out the symptoms are similar but the root cause is not, then the advise for each person diverges, and it can get messy and confusion.
It's great that you first searched for a solution. Too many don't and post a question that's been answered a dozen or more times. But when you don't find a solution, it's usually best to make a new post, especially if the original post is still active.
