Overflow filesystem mounted as /tmp in linux


If your “/tmp” mount on a linux filesystem is mounted as overflow (often sized at 1MB), this is likely due to you not specifying “/tmp” as its own partition and your root filesystem filled up and “/tmp” was remounted as a fallback. To fix this after you’ve cleared space, just unmount the fallback and it should remount at its original point:

sudo umount overflow

  1. I had a client whose mail was being delayed for un-explainable reasons, and found the “overflow” mounted /tmp, which was the culprit.

    I really want to thank you for the information – I’d never HEARD of overflow before. You’re a life-saver! (Well, my client and I both think so!)
