I am doing a dd on two identical drives with this command:
dd if=/dev/sda of=/dev/sdb bs=4096
Both hard drives are the exact same model number, and both have 1TB of storage space. /dev/sda uses a blocksize of 4096.
Is there a way to run this drive copy that takes less that 96 hours? I am o...
you don't really "speed up" dd. clonezilla is faster probably because it ignores empty space, so it doesn't copy each block. not sure if making block-sizes match read/write sizes would speed it up or not, but there was some discussion of that not mattering in Travis Goodspeed's goodfet talk.
@NathanOsman my laptop had an outage earlier when i hit 100% disk usage and didn't notice... so nothing was working right. still freeing up space. there should be a service that monitors that and pops something with notify-osd when you get close...
Is there a way to have Linux read ahead when cloning a disk? I use the program named "dd" to clone disks. The last time I did this it seemed as though the OS was reading then writing but never at the same time. Ideally, the destination disk would be constantly writing without waiting that's of...
There's been a number of questions regarding disk cloning tools and dd has been suggested at least once. I've already considered using dd myself, mainly because ease of use, and that it's readily available on pretty much all bootable Linux distributions.
What is the best way to use dd for clonin...
On occasion I've seen comments online along the lines of "make sure you set 'bs=' because the default value will take too long," and my own extremely-unscientific experiences of, "well that seemed to take longer than that other time last week" seem to bear that out. So whenever I use 'dd' (typic...
@NathanOsman I'm toying with docker and lxc. I like lxc giving me more control over the nuts and bolts, but I'm sure docker would be easier for orchestration.
The problem is shared storage on other platforms with boot2docker requiring setting up something to jump through virtualbox to the host.
@NathanOsman boot2docker lets you run a linux box inside of vbox and sets up basic networking for you... then docker runs in that vm, and it lets you run dockerized stuff on non-linux platforms with another layer of pain.
@Whaaaaaat They want to remove files from /dev/sda7. Of course the correct way to do this is to remove them from inside wherever it's mounted. But instead they have removed, or attempted to remove, /dev/sda7 itself. The other factor in play appears to be that they are unaware many commands, including rm, succeed silently, and are interpreting the absence of output as failure.
@Whaaaaaat Well if the only bad stuff they did was delete nodes in /dev, that should be fixable. I'm just not sure how / what the best way is to restore those nodes. There's a mknod command for this, but I'm not sure that's the best way. I wonder if udev would just put them back on reboot.
On the other hand, I'm not confident the system will actually boot back up, depending on what else they've changed in /dev. I think it will, but my knowledge in this area is not strong.
@Whaaaaaat Yes, that is strange. My guess is they saw some message that mentioned the volume by device name. But I'm not sure what.
systemd is a system management daemon designed for Linux and programmed exclusively for the Linux API. For systems using it, it is the first process which is executed in user space during the Linux startup process. Therefore, systemd serves as the root of the user space's process tree. The name systemd adheres to the Unix convention of making daemons easier to distinguish by having the letter d as the last letter of the filename.
== Components of the systemd software bundle ==
Systemd is not just the name of the init daemon but can also refer to the entire software bundle around systemd. This...
@NathanOsman A related source of confusion is that bash (since version 4 I think) accepts {0m..0n} syntax for generating 0-padded ranges, but still treats multi-digit numerals with leading 0s as octal in numerical evaluation.
ek@Ilex:~$ for i in {010..020}; do echo $i, $((i)); done 010, 8 011, 9 012, 10 013, 11 014, 12 015, 13 016, 14 017, 15 bash: 018: value too great for base (error token is "018")
I am trying to select a GUI for Ubuntu. If I just asked which one is best, I'd probably get a religious debate until the question was closed. But I'm asking which is the best fit for my needs, so here's a list of background details:
I just bought a used laptop (Intel Core 2 Duo, 2.1 GHz, 3 GB m...
double-click GUI sudo actions are not really secure, that's why we can't recommend them. (but of course we could also run Nautilus as root as long as we are not insane with what we do and rememer to quit Nautilus after finished...)
Sometimes I am forced to use really narrow Internet bandwidth of 56kbps. On my Ubuntu desktop I have too many programs, that frequently check something on the net - and hunting and disabling them one-by-one is really troublesome.
I'd like to have some tool, that would deny internet access (by w...
my History
I installed Ubuntu 14.04 LTS at /dev/sdb1 and Arch Linux at /dev/sda1.
Both swap onto /dev/sdb2. I tried (with succes) to install Arch Linux onto a SD-Card for my raspberry pi. There I tried to install vim to the SD-Card using pacstrap. This produced a few errors. After rebooting my ...
As many manufacturers of Notebooks do not offer any Notebooks without Windows preinstalled anymore, the next best thing would be a Chromebook.
I'd like to know how well do/will other Linux Distributions like Ubuntu and Fedora work on these new Chromebooks?
I talk about all kind of drivers, bat...
I guess someone could hotpatch the relevant socket calls and just error out if the md5 of the process binary isn't in the whitelist or something... but why would you need to?
Does we have any (single) canonical question about changing or setting default directories like:desktop,download,.. etc by XDG dirs? then give link of it. (~/.config/user-dirs.dirs or xdg-user-dirs-update)
The one you edited seems fine. It's good enough for now. That doesn't mean start hunting down all the xdg questions you can find and start duping them though.
@hbdgaf Is it not possible to provide single one which includes all option (so-that new users can find all info/dirs from that)? (or it is not Right way?)
I didn't have a problem with A ping. I had a problem with repeatedly editing a ping message ... so I get that irritating ding.ding.ding.ding.ding. sets to ignore
yeah - this commercial video playing in one of these tabs always makes me hate the webmasters of the site, and may lead to a permanent ban of the site from my side. :)
No. one reason I muted my speakers here at the office.
I have installed xubuntu-desktop in Ubuntu 14.04 so, starting & login screen changed to Xubuntu. Now how can I get back (return) default (Ubuntu) starting & login screen ?
hi every body. I have a new problem. I installed fresh ubuntu 14.04 and now I typing in terminal and pressing <Space> I get with delay and not real time
about ~0.5 seconds delay then reaction <Space> key

I still suspect it's a resource constraint. Like your disk is full or you're listening to one to many streams and listening to youtube while it happens.
Happened to me yesterday. "Why am I so laggy and idiotic errors?".... 2 hours later "crap, my disk is full"
