[Bug 1319667] Re: root file system 100% full, goes 52% after reboot

[Sergei Vorobyov]

1. I don't keep many files open forever, they are duly closed after
being used. Many created, filled up, closed, uploaded, and erased.

2. FIles get created on /home

3. / get overflown, not /home

4. If your explanation were correct, /home would have been overflown.

5. I think you explanation (not my report) is invalid. Please return the
status to "to be investigated/explained"

Title:
  root file system 100% full, goes 52% after reboot

Status in “e2fsprogs” package in Ubuntu:
  Invalid

Bug description:
  I am running several I/O intensive applications creating and deleting
  many files on the separate /home partition. After about a day of
  operation my root file system / containing everything except /home
  goes 100% full, although running ncdu -x from / shows just about 50%
  fullness. 100% goes down to (correct) 52% after a reboot. Note that
  all my files are created within the mounted /home partition. I do not
  run any specific process as a root (beyond those of a stock Ubuntu
  14.04 distribution).

  $ df -h
  Filesystem              Size  Used Avail Use% Mounted on
  /dev/sda3                23G   12G   11G  52% /
  /dev/sda6                98G   67G   27G  72% /home

  3) I expect my file systems to be cleaned up withoutr rebooting

  4) the root file system overflows just after 1 day of normal operation
