Programming :: C Program - Getting The Raw Size Of A Block Device
Oct 16, 2010How do you go about getting the raw size of a block device under Linux from within a C program? And I mean the raw size of the block device itself, not a file system that may or may not be installed on it. And I'd like to be able to get the raw size of any block device, from hard drives (e.g., /dev/sda) to LVM partitions (/dev/mapper/vg0-home) to loop devices to anything else that is a Linux block device.

Jan 23, 2011I found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

Aug 20, 2011i'm calculating the size of directories using "du"
PHP: function du($path)

exec ('du -sb ' . $path, $res[]);
$size = $res[0][0];
[Code].....
But then again, it doesn't calculate the actual file size, but rather a size aligned to 1024 bytes just as Windows does that with 4096 bytes cluster size. Is there a way to calculate the actual file size? eg. 1021 bytes
General :: Dd Block Input/output Size?

Ubuntu :: Mounting NTFS Changing The Block Size?
Mar 31, 2010I have reformatted my hard drive with allocation size 64K for a better performance on my WDTV HD media player(dealing with large files). When I mount this drive on Linux, the mount tells me that "blksize=4096".If I keep writing files usinghis default etting(blksize=4096) to my NTFS formatted hard drive, will my WDTV be able to benefit from the performance improvement of 64k allocation size ? Should I try and mount my hard drive with a larger blksize ?I did some research on google but couldn't find an option to increase the blksize when mounting an NTFS pre-formatted drive.

The results of the script would be that someone would kick off "linux_hosts.sh" r whatever you want to call it, then a top "folder" of options (with hosts contained within each of these top menu choices), then, based on which number corresponds to that top level, they're presented with a set of linux hosts that are relevant to that top level name.

General :: Cannot Mount Hard Disk: Block Count Exceeds Size Of Device
May 11, 2011I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:
Code:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:
Code:
dmesg | tail
[ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 122096646 blocks
The physical size of the device is 122096381 blocks
[code]....
this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?
General :: Generate Random List And Determine Size Of Arbitrary Block Of Files In Dir?

A cleaned-up and radio-ready portion of the list looks like

What I'd like to be able to do is zip all the files in the list into a single archive, to avoid the step of having to copy them to the same location (presumably another folder on the HD) and then zip that folder. I'm more inclined to make provisions about extracting to a single folder at some other time. Is this possible in BASH, or would I have to consider a faster, more robust scripting language such as python or perl?

Is there something that would tell me about mount points in Yast partitioner? So far I haven't been able to find that information anywhere. I don't want to lose information on existing drives and partitions but do want to be able to access them.Some of them appear under disk information in "My Computer" but if I try to mount them I get this error message.There is no application installed that can open files of the type block device (inode/blockdevice).I was trying to edit fstab,his didn't seem straightforward either. I've been hacking this about in other Linux distros - so not entirely clueless
