I have a couple of servers that are approaching capacity, however I can't seem to find where the space is being consumed? When I run:



[root@server /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
 40G 38G 76M 100% /
tmpfs 929M 0 929M 0% /dev/shm
/dev/sda1 485M 32M 428M 7% /boot


I can see that the / mount is filling up, so I then run:



[root@server /]# sudo ls | xargs du -hs
5.8M bin
22M boot
192K dev
25M etc
36K home
122M lib
19M lib64
16K lost+found
4.0K media
4.0K mnt
4.0K opt
0 proc
124K root
14M sbin
0 selinux
4.0K srv
0 sys
54M tmp
749M usr
61M var


and can't see any real directories that are using heaps of space. The biggest one is /usr at 749M.



Can someone please suggest how I can find out where all this space is being chewed up? Thanks.

Often times when something like this happens, it is due to some process keeping filehandles open on deleted (unlinked) files. If this is the case, you can find them by using lsof, for example:



$ sudo lsof +L1
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NLINK NODE NAME
tuned 869 root 7u REG 202,1 4096 0 4194380 /tmp/ffiGemRJt (deleted)
$


If you find deleted files are consuming much of your space, then it will probably be necessary to restart the offending process that is keeping the filehandles open.

Long meetings (6-7 hours a day): Being “babysat” by supervisor

Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 31 down vote favorite 4 I hold a PhD in mechanical engineering with a 7 year background in self-guided, self-paced research including 2 years as a graduate level course instructor and a subject matter expert for various engineering projects in a university setting in the United States. For the last 10-11 months, I am working in a research industry in France where my task is to debug C++ spaghetti code written over a period of several years by my current supervisor. It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala
