I created a VM disk image with kvm-img, but I forget what was the max size of that disk image when I created it. Currently, its size is 6.2G, I want to install some large packages in that VM, so I want to make sure the disk image can expand to an adequate size.

View 2 Replies View RelatedFirst off all, I'm booting from a large MEMDISK using PXE (900MB) . Due to our environment, I cannot decrease the size, nor move files to a nfs/iSCSI/... environment. Everything needs to be in that MEMDISK.
Now, when I try to run the OS, I get out of vmalloc space. How do I increase it to a number which allows such a large image to be mapped? I tried the parameter "vmalloc=1280M", but with that parameter, I don't get past the Booting the kernel screen.
Memory should not be an issue, since the machine(s) have at least 2GB RAM. (900MB MEMDISK + 256MB for other kernel stuff + 768MB for user stuff). The machine(s) have a Pentium 4 Extreme Edition processor, with hyperthreading and SSE2, but no EM64T.
How can I boot the system, and get past that message? Decreasing the MEMDISK size is not possible too. It is at the smallest we can get with our userland + kernel + modules.
How do I change the size of the available shared memory on Linux?evidently 4GB is not enough for what I am doing (I need to load a lot of data into shared memory - my machine got 8GB of RAM).
View 2 Replies View RelatedI'm using fc14 and the SG driver to test some SCSI (SAS) targets. In doing so, I'm bumping up against what appears to be a 512KB maximum transfer size per command. Transfers up to 4MB sometimes work, but often they result in ENOMEM or EINVAL returned from the write() function in the SG driver. I could not find any good documentation on how the SCSI system in Linux works so I've been studying the source for drivers in drivers/scsi.
I see that there is a scsi_device struct that contains a request_queue struct that contains a queue_limits struct that contains an element called max_sectors. The SG driver seems to use this to limit the size of the reserve buffer it is willing to create. I see that there are several constants used to initialize max_sectors to 1024 which would result in the 512KB limit I see (with targets having 512 byte sectors). At this point I have several questions:
1) When the open() function for the sg driver gets called, who initializes the scsi_device struct with the default values?
2) Can I merely change the limits struct to arbitrary values after initialization and cause the SG ioctls to set the reserve buffer to allow greater values?......

I have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk?
For example:
> du -s --si --apparent-size Jimage.image
120G Jimage.image
> du -s --si Jimage.image
121G Jimage.image
This actually only has 50G of real data on it, though, so the second measurement should be much smaller.
This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.
I know there are many threads about recovering damaged superblocks. I've spent 3 evenings reading them and trying what they suggest. Invariably the commands do nothing except to report bad or missing superblocks. I've removed the physical disk from the machine and am working with a dd image file (/mnt/image). I can mount what used to be hdc1 and read its files with no problem. I'm trying to recover partions hdc6 and hdc7.$ mmls /mnt/image -b

I have written a script.
#/bin/bash
a=`du -sh /root/samplefolder | cut -f1`
echo $a > testfile
[code]....
The aim of this script is, when the folder reaches 20M then attributes will be set to that particular folder so that no newfiles and folders cannot be created or copied to that samplefolder. whenever i copy a file morethan 20M to that folder its getting copied fully and then the attributes were applied. But i dont want this to happen, when the folder reaches its maximum current write operation to that folder should be stopped automatically with a error.
I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:
View 2 Replies View RelatedAfter screwing up an update to Ubuntu 11.04 I decided to do a clean install. I tried downloading the AMD64 DVD image of 11.04 but I have found that some of the files cannot be downloaded and appear to have bad file size. In several mirrors and repositories I found the image size to be only 46.1 MB! (Yes, thats "Mega"-bytes, not Giga-bytes. I ftp'd to the repositories/mirror sites and confirmed this.) Yet in many of the HTTP pages it shows as 4.0 GB.I can't believe that the true size is 46.1 MB as the i386 DVD image is over 3 GB. 4.0 GB sound right, but doesn't match the actual file size. So, how long until it gets updated?

It's not an option to clone the HDD again, I know how to do it if I had only cloned the single partition by itself. I hope it's still possible with the current image.
I have created an image out of 2 other images using the "montage" command. I want to then print it using "lpr". I view the output from montage in XV and it looks fine however when I try to print, it prints the bottom half of the first image then the second and then the bottom half again.
E.g., imagine this:
Code:
<< end of top image
<< end of bottom image
The above is how it looks in xv however when printed, it looks like:
Code:

I really can't understand it, I've tried opening and saving the image again but it still prints as above. I don't know if montage is outputting it incorrectly or something, however it looks right on the screen!

When I try to burn some .flv files onto a DVD iso using K3B, it gives me the message: "Could not determine size of resulting image file"
View 1 Replies View RelatedI am having trouble both installing or even just booting the live CD. I have to interrupt the boot to give the nomodeset boot option.
Once I get the Ubuntu splash with the oscillating red and white dots for several moments, I get the Busybox with the error message "Unable to find a medium containing a live file system"
If I do a dmesg I then see a lot of sr0 errors. I have an onboard SCSI controller but no scsi devices. I am not sure if this matters.
When I first installed K3b it burned the first track with no GUI user configurations.The second time it says that the file name is too long and asks if you want to catenate (shorten) it even if it is the same file you have already burned that didn't ask for this shortening of the file name before. Than it gives you an error of "Could not determine size of resulting image file". So my question is how do you use K3b I guess. Brasero won't do multi-session as far I can deduct. It will ask if you want to do it but after ask if you want to erase the disc.If you force it there is no entry of the previous burns.If I could get Brasero to muli-session it would sovle my problem as well. Here's the debugging stuff. I'm using this on Gnome.
