How can your disk be full when df shows otherwise? "Inode" the answer!

Sorry, I just couldn't resist.  That's probably the only time I'll ever get to use that joke.  I had a situation recently where I had a system that kept giving errors that the root volume was full, yet df -h showed plenty of available space.  After doing a bit of digging, I found that there were hordes of tiny files chewing up inodes far faster than the space on the drive.  Essentially, this would be like filling a file cabinet full of folders with only a post-it note inside each folder.  The majority of the volume of the cabinet would be taken up with folders rather than "data."

I could detail how to diagnose and fix this issue, but someone has already written an excellent blog post on how to do just that.

No space left on device – running out of Inodes

Thanks to Ivan Kuznetsov for taking the time to post his tutorial!

If you've gone the virtual route, take note:

Virtualization is cool... literally

I happened to notice that removing yet another rack of equipment  that our ambient temperature in the data room has dropped even more.  It doesn't seem like that long ago when we would struggle with keeping the temp under 85.  Going the VM route sure took care of that issue.

Remmina won't connect to Windows machines?

If you're like me, you still have to deal with Windows servers in your environment.  I typically RDP over to the ones in my environment with Remmina.  Every so often I run into an issue where a saved RDP connection will stop working and I have to blow it away and recreate it.  I finally had my fill and looked for a solution today.  Apparently the fix is to just change the security method from 'Negotiate' to 'TLS'.  Amazing what you can find when your annoyance level exceeds your laziness level.

Take a look at the original post where I found the fix over at Bauer-Power.net.
