When I try to install anything recently, I was getting errors about "No Space". I noticed that the root drive (/dev/sda1) has 100% usage which I'm not sure how that suddenly happened.
Code:
tom@HouseMedia:/$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.0G 9.0G 0 100% /
none 1.5G 552K 1.5G 1% /dev

/dev/sdb1 294G 182G 97G 66% /mediastorage
There was a powerloss recently and I wondered if some serious corruption had occurred. Since I'm checking the root drive, I had fsck run after a restart:
Code:
sudo shutdown -F -r now
FSCK went to work, briefly, and the logs (/var/logs/checkfs and /var/logs/checkroot) remain empty. Speaking of log files, I had a look at all of them and they take up a mere 32MB, so that's not the issue...
Code:
tom@HouseMedia:/var/log$ ls -h -l
total 32M

Have already ran apt-get clean. How can I figure out what is taking up so much room? How can I go about figuring out what is huge and is safe to remove?
My requirement. We have a linux File server which was connected to SAN (IBM DS4700)now I need to increase my capacity by 50GB I've added the 50GB through the IBM storage manager to the File server, but it doesn't showing on my linux file server
bellow the detail of my drives

I need to add the 50GB on to the "mpath0p8".
I am writing some server programs. I notice that I can only connect to the server with a total of 28232 connections (clients) before I get the errno [99] "Cannot assign requested address" from the client program. I am using the same machine to do both operations. It seems like I am reaching some networking limitation outside of both programs.The server process has a maximum of 6 theads running(well below the thead limit). The client has two threads. When I add another client machine to the testing I can surpass 28232 connections). What limitation am I reaching on the server machine and how can I overcome this limitation. Again when I add a client machine to the testing, I can achieve more than 28232.
System Setup:
SUSE 11.1 64 bits
ulimit nofile=150000
I have a total of 4 hdd's, 500gb 7.2rpm that I would like mirrored using raid 10. As you can see from the image, ubuntu 9.10 server isn't recognizing the full 2tb's. In fact, I'm not even sure about the configuration as I was thinking the HDD's would come up as four 500gb hdds. Instead I have the configuration above set and ready for Ubuntu to be installed on.
1. Is this typical of a server pre-configured from Dell(perc6 raid controller.
2.Why is ubuntu not recognizing the full capacity of the drives especially when it's a server install?
Let's say I am pinging a host, and want to output to a file each reply and its timestamp of when this started.
I know that it can be done with a loop and a shell script. Something like this
DO
echo "$(date)" >> results.txt ###includes the time and outputs results to txt###
ping -c 4 HOST >> results.txt ###a total of 4 pings at a rate of 1 per second###
REPEAT UNTIL USER PRESSES CTRL-C
Now, my first issue is that I need to be able to see results real-time as well.
Is there a way one can print to BOTH a screen and output? If one uses the ">>" command, it is essentially sending everything to the file. Running another ping command in parallel is not an option.
I have 2 servers each one with a RAID and I want them mirror they data so if one of them goes down the other one take the job with out disruption. I've heard of multipath by I want to know it in detail or learn of more options.

I have a real system user say 'test', created in a number of system groups, up to 3 additional groups (including ftp of course). Its set to the usual standard directory /home/test. But what if I wanted to use /home/test as their home directory but login to what would be unknown to them to be ProFTP to make them go in say [URL] or something random like that, how is this done? Just been through things like this:

We have a production web site running apache 2.2.3 across several web servers. we also have a major problem with SPAM comments right now. our method of identifying valid IPs (whether by external clients/customers, or internal personnel) vs SPAM'ers is not ideal - its prone to erroneously labeling legit IP's as targets to be blacklisted.
What we need is.. a way to see how much distinct request traffic is coming from any given IP address to the site in real time (or very near realtime). Essentially we want to see in some graphic/chart way requests per sec to apache / per ip sorted by requests per sec.Would nTop do this? I've only used this in a limited form at a branch office, not on a production web server.
what the recommended way to set up real-time (or near real-time) folder synchronization among 2+ servers. I looked a rsync but that doesn't sound real-time and it looks like its something that you might put in a cron once an hour.
View 1 Replies View RelatedI have a 650 GB ext3 LVM partition with RAID 1 on. The partition is 85% full, but the system says "no space left on device" - where did the 15% go?I ran "tune2fs -m 0 /dev/mda1", so it is not the space reserved for the root - so Nautilus reports the same free capacity as GParted now.Some more info:- Ubuntu 9.10 x64- GParted says 650 GiB, 104.83 GiB free- Nautilus says 104.8 GiB free- The system thinks the disk is completely full - I cannot even create (touch) a new empty file

View 1 Replies View RelatedI can use dvd+rw-mediainfo to report the capacity of a loaded blank recordable DVD. Does anybody know of an equivalent program for CDs?
View 10 Replies View RelatedFirst of all, this isn't really a problem for me, but I'm just curious. In the past when I started a data CD project, I remember that k3b used to start me with a "blank CD" of 700MB and then expand to a "blank DVD" of 4.4GB when the amount of data exceeded the capacity of a CD. Normally I just make an ISO image for the CD and burn on another machine (for a reason not relevant here).
Today, it started me off with a "blank DVD" right away. It's not a problem because the ISO format isn't different and the data is under 700MB anyway. How come? Ah wait, I think I know what it is, there's a DVD+RW in the drive at the moment so k3b got too smart and assumed that I wanted to write to it, even though I selected Create image only.

my laptop battery capacity has gone low due to constant charging or whatsoever reason. previously it was at 62% and within 2 months its gone down to 32%. I use the laptop atleast for 18hrs every day. so is ther any solution to prevent my battery from losing the capicity.

I've recently completed a fresh install of 10.04 on a home file server and upgraded the hard drives in my storage array. My PREVIOUS hardware was:
Old version of Ubuntu (I forget which one exactly, but I know I had missed a few upgrade cycles)
3X 500 GB Seagate Baracuda's (for the array)
Areca 1220 Hardware RAID controller
Intel Core 2 Duo 6600
320 GB Seagate for the boot drive
I was running that hardware for about five years or so and it was rock solid. After the upgrade the hardware specs are:
Ubuntu 10.04
Areca 1220 hardware RAID controller
4x 1000GB Samsung
Intel Core 2 Duo 6600
320 GB Seagate for the boot drive.
The fresh install of Ubuntu 10.04 went remarkably well. The drivers for that raid controller are in the kernel, which is great. I was able to access the old array after upgrading Ubuntu. Now I am trying to create a new array with the four 1000 GB drives in a RAID 5. Obviously that gives a maximum storage capacity of 3 TB, greater than the 2 TB threshold that seems to be so important. I've been doing some digging and here is where my questions start:
it appears as though gparted doesn't support file partitions greater than 2 TB, correct?
it also doesn't seem as though parted supports ext3 or ext4, is that correct?
If this is the case, how do I create a partition with ext4 that is greater than 2 TB?
I can see the array volume in gparted (which is a relief) but it lists the size as 2.73 TiB, which I find curious because that is over 2 TB, but not the full capacity of the volume. I can also get to the volume in parted. But I see in the parted documentation that using the makepartfs command is discouraged and instead, one should use the command mkpart to create an empty partition, and then use external tools like mke2fs ( to create the filesystem.
how to proceed from here. What does the community think is the best course of action to create a partition of 3TB in ext4? Then I need to change fdisk to automatically mount the array at every log in, right?
I have window 7 and Ubuntu 10.04 on my laptop.As you know if I extend the capacity of my ubuntu partion in window, I will lose ubuntu and I should reinstall it.I want to know if there is a way for extending my ubuntu partition from 20 Gb to 30 Gb without loosing ubuntu and windows?

I just bought a laptop with a T4400. Looking through lshw output turned up the following for the L2 cache:
Code:
*-cache:1
description: L2 cache
physical id: 6
slot: L2 Cache
size: 1MiB
capacity: 4MiB
capabilities: burst internal write-back unified
I'm curious as to why the size (1Mib) and capacity (4MiB) are different. Surely it can't be possible to stick something on the CPU to increase the L2 cache size, right?? So what does this mean?
I'm running 64-bit Linux Mint (derivative of Ubuntu). The kernel config says CONFIG_X86_L1_CACHE_BYTES=64 but I found nothing about the L2 cache.
Can I somehow unlock more cache to get a 4MiB L2 cache for free?
My specs: Debian Lenny i686, 7gb ram, 1tb hdd, Pentium 4 2.2 the rest not important.
Now, i did clean install of Debian on to my 1tb hdd as such:
- 14 gb swap (as far as I understood it has to be twice as ram)
- / root 25 gb
- /home the rest
I don`t know if it`s important, but I am under Gnome+Compiz+Emerald.
So the first question is: There is a program in: Applications/SystemTools/Disk Usage Analyzer It tells me thisScreenshot-Disk Usage Analyzer.png
Correct me if I am not right, but i am running out of disk space on /home?
i have a macbook air, just recently got it. and i am trying to experiment a little bit and use DSL instead of a full fleged version, I have the ISO, and a pen drive, and acsess to startup manager, but the pen drive never shows.
