Fedora 26 No Space Left on Device with Plenty of Space Available
-
So my question is: Why did a reboot fix this? @scottalanmiller's available inodes should be exactly the same, unless he has a container running that is creating and deleting files very frequently
-
Thanks for the explanations. It helped me search better, and I eventually found this: https://www.ivankuznetsov.com/2010/02/no-space-left-on-device-running-out-of-inodes.html
Shows how to check available inode space and how to fix it as well.
As for Scott's problem, I'm guessing something creating a lot of temp files that are cleared during a reboot.
-
@tim_g If it's the same file system wouldn't that keep the number of temporary files down to a minimum? Legitimately asking, not being snarky

Usually comes from orphaned INodes. Can happen if the process halts or server is shutdown incorrectly. This is what the lost+found directory is for.

It did not. Deleting millions of unneeded files did.

Seems weird to me that this can happen. This inodes thing is completely new to me. I had to look it up, and know almost nothing about it. Seems like a major Linux turn-off if this happens for no reason.
Maybe I need a good explanation, if someone doesn't mind.
It's one of those weird things that on tests and in classrooms people talk about constantly as if it is an every day thing. But in the real world, with thousands of servers over decades of use, I've actually had this happen now... once. I am an idiot for not checking that straight away, but it is so insanely rare in the real world that it never occurred to me that it was a real possibility. Especially when the system had no reason to be making so many files.

@scottalanmiller I could've sworn there was a post here related to a reboot solving it

It's not Linux related. It's filesystem related. And it is so insanely rare that it's not a thing to worry about in the real world. Windows has inodes too, they call them File ID.

Someone mentioned rebooting to try to solve it. But it did not (had already done that.) It was real files causing the issue, nothing orphaned. Literally, we were making 30K files an hour or so.

Tiny files to, right?

That is not relevant except for that fact that large files would have filled drive space and likely been noticed.

Empty I think. Tons were just folders.

How is that not relevant? More files = more inodes being used

Size of the files is not relevant. Pay attention to what is said.

It actually makes sense that @scottalanmiller said it was mostly directories. Files of any size will almost always run out of drive space before inodes run out in 99.9999% of situations. This is the first time I've actually heard of this happening, ever.
Only not relevant for those who actually know about inodes already. The only reason I even know about them is they got mentioned in SGI's IRIX Sysadmin courses.

Ya I've never run into it in the real world only on trick questions

The one major exception is marker files. "touch thishappened" as a file automatically and never clean up and you are using inodes without using any space. That's who you can easily learn about inode depletion. But who does that?

People writing bad scripts that use lock files and forget to remove them.
That wouldn't create enough to do this though.

I understand. I've done a lot on Linux over the years and I've never run into anything having to do with inodes. That's why I was clueless and had to ask.
