how can change this ? maybe a kernel bug ?

Yesterday, when I was trying to install TeX Live, it stopped in between saying that there is no space left in File System. Even though I have space in my hard drive volumes, space seems to be running out of my system partition which is only 9GB in size (I guess!).I am posting a few results that might help you guys. I have an unformatted 15GB partition. How can I add it to my system partition? And is my var folder too big (1.5GB)? If yes, how do I backup its contents and then delete them? Additionally, the File System shows a folder 'media' (89GB) which links the C: drive that contains Windows 7 and my personal files. Should it remain that way or should I separate it? If the latter, how? I just couldn't find any.

I know that,the graphical user interface ( using X windows , I think ) sits on top of the base system ie F1 to F6. In the Fs , xrandr replies "Can't open display ". The question is am I right in thinking that "gui" is totally independant of the base ( is that the correct word ?). I have read that messing about with resolution can wreck a monitor ( I'm using a laptop) , is there a safe way to proceed?

View 8 Replies View RelatedI am working on a C++ application, using the latest Slax as distro and CodeBlocks 8.02 as IDE.
I have a problem that is really biting me hard... And i'm sorry if my questions will sound trivial: i'm still a C++ noob...
Basically,looking with KSysGuard i can notice a constant increment of the VmRss parameter,i.e. the resident set size of my program.
While stepping with the debugger i noticed that the VmRss parameter increases by 4 (KB?) when i push_back into some STL vectors (i have this problem in various parts of the code).
While i analyze the problem with KSysGuard i'm also looking at the /proc/statm file of my process. When KSysGuard shows a VmRss increment by 4, i can actually see an increment (by 1) in the 2nd parameter of that file (which is the resident set size) but not in the 1st parameter (which is the total program size).
What surprises me most is that the VmRss is reported in KB and i really am not pushing 4 KB inside the vector all at once...
So i ask:
1)Is this a memory leak?
2)Why the total program size doesn't increase?
3)To me, it looks like VmRss increases "cumulatively" only after several insertions in the various vectors.
Based on the reading I've done over the past 48 hours I think I'm in serious trouble here with my RAID 5 array. I got another 1 TB drive and added to my other 3 to increase my space to 3 TB...no problem.
While the array was resyncing...it got to about 40%, I had a power failure. So I'm pretty sure it failed while it was growing the array...not the partition. Next time I booted mdadm didn't even detect the array. I fiddled around trying to get mdadm to recognize my array, but no luck.
I finally got desperate enough to just create the array again...I knew the settings of my and had seen some people have success with this method. When creating it, it asked me if I was sure because the disks appeared to belong to an array already, but I said yes. The problem is when I created it, it created a clean array and this is what I'm left with.
Code:
/dev/md0:
Version : 00.90
Creation Time : Sun Sep 5 20:01:08 2010
Raid Level : raid5
Array Size : 2930279808 (2794.53 GiB 3000.61 GB)

I tried looking for backup superblock locations using e2fsck and every other tool I could find, but nothing worked. I tried testdisk which says it found my partition on /dev/md0, so I let it create the partition. Now I have a /dev/md0p1, which won't let me mount it either. What's interesting is gparted reports /dev/md0p1 as the old partition size (1.82 TB)...the data has to still be there, right?
I'm currently setting up a server with 2x 1TB disks in raid1. (Centos 5.5)In the future, if the storage is insufficient and I decide to upgrade the disks to 2x 2TB, could I just:
- dump ghost image of the array on usb drive
- replace hdd's and build new array
- ghost array with image created previously
Would the above work, will the new partition automatically resize to 2TB or do I need to partition right now with LVM? would it work with LVM?

View 3 Replies View RelatedI recently installed Bio-Linux 5.0 as a dual boot system with XP for some bioinformatics applications, but Im having some problems with the amount of disk space which can be allocated specifically for the Ubuntu install.
I partitioned a 250 GB portable hard drive into:
/dev/sdb1: 154.76 GiB (with 30 GiB allocated for Ubuntu)
/dev/sdb2 : 78.13 GiB
Ive been using blastclust to analyse some very large data sets, which keeps on crashing due to filesystem running out of disk space.
When I installed Bio-Linux 5.0 from the live cd, the maximum size I could allocate to the install was 30 GiB, and I havent been able to find a way to change this.
Ive tried using System->Administration->Partition Editor using the live cd, and can view / delete the partitions, but I cant find a way to specifically alter the disk space allocation for Ubuntu.
How do I increase the filesystem size to larger than the current 30 GiB?
Is there a way to clean (reduce size of) the abrt cache (/var/cache/abrt)? Perhaps something similar to "yum clean all"?
View 1 Replies View RelatedI 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?
How do I get the L2 and L3 cache size?
View 4 Replies View RelatedDoes anybody have some thoughts about a local dns server cache size? What is the optimal one? In terms of memory consumption and number of re-enters into the cache. Lets say that default size is 150, so I've change this to 500 and after some time I see 379 re-enters into the cache. Simply put I need to increase the cache size 2 times. But due to the fact that browser preloads dns names it is not possible to interpret the number of overwrites in terms that it is not possible to say if useful cache entries were overwritten or those that the browser precached ( in other words not needed ). In this case it is ok to overwrite unwanted entries because it is not likely that I'll need these entries anyway
I'm running the dnsmasq on an embedded system with limited ram and with an umts dongle attached. It is important to keep the cache size as small as possible to reduce memory usage and at the same time to reduce number of external lookups because dns latency of the umts connection is high (1-2sec for the dns query)
I've got a server that needs more space. To achieve this we added space (by extending the VMware disk attached to it).Normally this isn't an issue, because we just add an new partition and LVM it from there, but this host predates our deployment of LVM everywhere.
Our current theory is that the unallocated sectors can not be assigned because they aren't part of the extended partition, and thus ... we go in a circle.So what i believe the way forward is to extend sda4 so that i can then create an sda10 inside of it. Anyone have any ideas on how to do this? I was thinking gparted may do the trick ... but being a server i'm in runlevel3, with no X...

View 2 Replies View RelatedI have a 30" LCD with 2560x1600 pixel resolution. I would like to make and play videos at this resolution, but software decode is too slow, and the GPU accelerated decode (VDPAU) maxes out at 2048 pixels. It might be possible to decode 2Kx2K and cut-and-paste and reorganize the rectangles to fill 2560x1600. But someday I plan on getting a 4K screen (4096x2160 pixels) and I would like to support that too. For that it seems two video streams decoded by two GPUs and exactly synchronized would work.
