As I suspected, the free space usage does not decrease with a reboot, meaning that the written-to space is not in /proc or /tmp. This is very strange then, since the find results indicate that no file is being written to rapidly, but the block_dump indicates that some blocks (not inodes) are being written to.
It seems to point to a kernel bug that spams WRITEs to contiguous free blocks but not storing any meaningful files to those locations. -- kjournald2 writes to disk about every 10 seconds https://bugs.launchpad.net/bugs/442443 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
