Ubuntu :: Disk Filling Up - Disparity Between Df And Du?
Feb 19, 2011
For a while my root partition has been filling up for no apparent reason. I I have been deleting things to find out it fills up again in a mater of days. To make it more 'interesting', there is a disparity between what I get from df and what the du command is telling me. After dismounting the other file systems and turning off applications, this is what i get:
output of df -ha
Code:
Filesystem Size Used Avail Use% Mounted on
/dev/sdf5 69G 66G 54M 100% /
proc 0 0 0 - /proc
none 0 0 0 - /sys
[code]....
du claims that I'm using 29G on that partition, which sounds about right (this is my OS and basic /home partition, everything else is elsewhere). df on the other hand is telling me here that out of 69G, 64G are in use with only 54M left.

I have a lot of data on a nfs store external to an Ubuntu machine. I've had problems with the storage becoming full and have spent a very long time deleting files to get absolutely nowhere! Over 25GB of deletions on the 80GB disk has only cleared 1.5GB of space...
You can see below the hidden .snapshot directory, the disk usage for the nfs-store is coming out at 97GB when the disk is only 80GB in size, and the two directories I want on the disk are about 22GB in size.The .snapshot directory appears to have been made on Friday, I'd like to know if I can:
1) find out what command ran to create/update it
2) re-run the command to update the directory or remove the directory
Code:
ideasadmin@ideasadmin-desktop:/nfs-store$ ls -la
total 20
drwxr-xr-x 5 500 500 4096 2010-07-16 17:35 .

Noticed that one of my partitions on openSuse 11.1, mounted as /usr, filled up suddenly with over 20 GB of something. Tracked it down to /usr/bin, in which the X11 directory contains 2353 items and another X11 directory, recursively at least 11 times that I've expanded without reaching the last X11 directory. The newest files in each directory are dated 11/24/10.
Any idea of what's happening? How to stop it before it fills the disk?

I'm running an OpenSuse 11.2 box at home which updates a mysql database 4 times a day then posts 34Mb to my website. It's exactly the same amount of data each time, and my scripts*TRUNCATEs then rewrites the database with the latest data - so the database size remains the same.
There's a problem (I think with the script) however which means that everytime the script runs, approximately 34Mb of space on my hard disk is mysteriously taken up. I'll have to get that script fixed...
I can't, however find the files which are eating up my diskspace at the rate of 140Mb per day. I've done various searches (mainly with Dolphin) including hidden files immediately after running my flaky script and looking for any files created/modified in the previous few minutes when the 34Mb has disappeared.
There are LOTS of files in /proc (which I don't think is actually on my HD right?) and also in /var. There's nothing much in /tmp (on a separate partition) or any log files that I can see. The box has been running this script daily for the last 6 weeks so I'm hoping there's a load of files somewhere I can get rid of, then fix my script.

When I run Htop on my Ubuntu 10.04 machine, the "Mem" line reads 239/992MB.
However, when I run 'top' I get:
Also, when I run 'free', I get:
It seems like Htop tells me I have more than 700MB free, but 'top' and 'free' tell me that I only have about 270MB free.

I have a RHEL5 server that hosts an apache SSL proxy and about 20 tomcat instances. As of late we've had latency issues on the system that I can't pin down. In trying to diagnose whether the local HD is being over-utilized, I started gathering disk utilization stats using iostat and sar. For Sar, I'm using the "tps" metric, and for IOStat I'm combining reads and writes per second for the raw disk device, sda. When I put the stats into excel, the profile of the graphed data points match up for the most part, but sar is reporting the values for the same data points as being many magnitudes higher. Can anybody give me a hint as to why one tool would report the same data differently when (as far as I know) both of them pull their disk I/O stats from the same place?

I have a pre-printed form that I need to fill in. Is it possible to scan it, fill it in on screen, and then put the original form in the printer and get things to print out on that original form? I know that I can scan the form and fill it in on screen and print out on a blank piece of paper, but I need to use the original form

Just today I started getting notices about lack of disk space on my system. After much digging I found that .xsession-errors and .xsession-errors.old were taking nearly 70GB of space combined. The primary message I'm getting over and over again is: SSL_Write: I/O Error I have been unable to figure out what's causing this error.

Some of my cronjobs are filling up files in my / directory. How do I make this stop? One of my cron jobs uses wget:[URL].. The bexcb0.php file writes a file and then echos a result if it is sucsesfull. These echo results are being put into bexcb0.php files in my /root folder and are piling up.
My / folder is filling up with files bexcb0.php etc bexcb0.php bexcb0.php.1 bexcb0.php.2 bexcb0.php.3 bexcb0.php.4 bexcb0.php.5 etc How do I make this stop? If I just remove the echo will they stop writing to the / folder?

I am using my ubuntu server as my home router.Everything is working as expected with one exception.y DSL modem is a POS and every now and again it looses connection to the router. Sometimes it needs to be reset and sometimes it does not.Either way, when this happens my ubuntu server needs to reacquire an IP from my ISP. If it screws up when I'm at home it's no big deal, but if it happens when I'm not around my housemates have taken to hitting the reset switch on the server. I'm not a big fan of this so I wrote a script to ping my ISP's gateway. If it's unavailable it bounces the eth0 interface and tries to get an IP. I am running this script every couple of minutes in a cron job. Now I'm getting syslog entries like

I have a number of servers I manage, and one of them is archiving old data that is never modified on a separate partition. This partition is at 100% capacity. A friend of mine says this is an unsafe way to keep this partition, even tho I don't plan to add any more data to it or change anything within. I know I can archive the data to dvd, but I'd like to keep the data online for my users.
What are your opinions on this? Can I keep this archive partition at 100% capacity? Or do I risk some sort of data corruption? Should I mount this partition as read-only to help prevent any corruption?

I'm booting to Kali 2.0 live from USB and wanted to add persistence, but I can't get OpenVAS setup. The setup script runs and eventually fails due to no more disk space. Here's my df -h output:
Here's gparted:
When the setup runs it fills up root (/) which is only 872mb. This is a 16gb USB so I'm wondering if there's a way to allocate some of the 11gb of unallocated space to root? I couldn't tell how to do this with gparted, would I need to build a custom Kali iso or something with different partitioning?

I'm getting the following messages sent to my root account mailbox. It appears to be reporting an issue finding ntpdate, however when running the following command:
aptitude show ntpdate | grep State
It shows as installed and any ntpdate commands work with no issues, so I have no idea why this is getting regularly reported?

I have Lucid 64 connected to my 27" TV with 4:3 aspect ratio via s-video from an nVidia NV4 GeForce 6200SE TurboCache 256 MB card using the 173 driver set at 800X600. After hours (don't get on my case, this is the first time I've had hardware that would run well on a TV) and hours of tinkering I've gotten a feel for how to do this and have some pretty good results. However, I have two problems.
.01 The display isn't quite filling the entire screen. It's leaving about a .25 inch black bar all the way around the screen. This is negligible and if I can't fix it with only minor adjustments then so be it. I can live with it.
.02 This one isn't so minor. Many of the Windows are opening with portions of themselves cut off of, usually, the bottom of the screen. This makes, among other things, getting to the Close button rather impossible.

I have some ideas about writing a small game in terminal ( just for fun ) using ncurses library. I want to use some kind of menus (in Midnight Commander's style), but there are some problems with rendering windows, that I don't understand. I create a window with newwin(), assign a color pair to it calling wattron() (for example, I want to fill a window with blue background), and then I call my own function wnd_fill() :
Code: void wnd_fill (WINDOW* wnd)

I would expect this behavior if "domain.com and anotherdomain.com" wasn't a domain that I hosted. But this is a valid domain that this server should be answering for. In my named.conf I do have the
Quote:
allow-query { any; };
option on every zone. This is my slave server and I have the primary shut off so I can test this slave server. FYI: So far queriers still seem to be working. The pages for the sites are still coming up via the internet.

I'm at a web page for an organization and I want to get a bunch of information -- say the addresses of 20 members of the organization. The web page presents a javascript form looks something like:
First name: (textbox)
Last name: (textbox)
State: (textbox)
Member status: (radiobutton)
Find: (button)
It then provides the mailing address and telephone number of the member. I don't want to enter the data by hand 20 times, but would prefer to fill out the form automatically from data in a text file or database or script or whatever. Is there a tool in linux for doing this? I looked up curl, but it seems that I can do it in curl only if they are html forms, but not js forms (or more correctly, I haven't figured out how to do it). Moreover, the page returned by curl is not the page that comes up in firefox; I don't know why.

I know that this issue has been brought up before but I can't quite find the answer I am looking for. I have several servers where /var/spool/clientmqueue is filling up with unsent messages. I know this is because I have disabled sendmail on these servers. My question is how do I get it to stop and leave that poor directory alone?

In the last week email delivery had slowed down to taking approximately 24 hours and investigation has revealed that there were 45000 emails in the mailqueue. I flushed the mailqueue yesterday but mail delivery is slowing down again because emails are again being queued by the thousand.
The mails are mainly spam sent to ficticious users at a genuine domain hosted on the server.
My setup is running Courier IMAP with Postfix, Spassassin is installed along with Amavisd-new but I just don't understand why this has suddenly become a problem based on my setup not having changed for the last 6 months.
Should these spam emails be being discarded by spamassassin before reaching the mail queue? Are my discard score settings too high (6.9)?

I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.
