First: Make sure to shut down the virtual machine or to unmount the disk inside it. Once finished you can start to extend the logical volume on the hypervisor: lvextend -L+400G /dev/vg0/disk e2fsck -f /dev/vg0/disk resize2fs /dev/vg0/disk There might be a chance you need kpartx, growpart (provided by cloud-guest-utils) followed by resize2fs to grow the mounted partition. In case you shut down the virtual machine you may start it again with...

Recent versions of Firefox include the ability to sync your bookmarks, passwords, preferences, etc. with a remote server. You can choose between a server provided by Mozilla or a custom server. There seem to be two solutions to deploy a custom server: Firefox Sync Server http://docs.services.mozilla.com/howtos/run-sync.html FSyncMS https://github.com/balu-/FSyncMS/ Firefox Sync Server requires Python 2.6 and Virtualenv. Since there are no packages for Debian you will have to use make and install some libraries to get it running....

setup: server with configured software RAID1 and LVM. If you have configured mdadm monitoring correctly you might receive an email like the following one day: A Fail event had been detected on md device /dev/md/0. It could be related to component device /dev/sda1. This requires immediate action because one of your hard disks is possibly broken. # cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0](F) sdb2[1] 2929739071 blocks super 1....
If you’re running ownCloud on a server with FCGId you might wonder why login to the web interface work flawlessly but your sync client keeps saying that the provided credentials aren’t correct. The problem is, that the webdav auth done via remote.php (this is actually used by the sync client) is not able to process the credentials because of FCGId. The following .htaccess in the root folder fixed this problem for me, you need to enable mod_rewrite for this to work....
byobu basically is a wrapper for screen or tmux and is available via the repositories. You don’t have to mess around with the various screen/tmux options anymore since byobu provides an easy to use interface. Added bonus: byobu displays status notifications like time, RAM usage or uptime in its footer. One can add or remove more notifications by pressing F9 and selecting “Toggle status notifications”.

It’s even possible to mail the changelogs to a provided email address.

I’ve always been looking for a command-line based download manager but the few available solutions didn’t satisfy my requirements. Today I stumbled upon Cuddle which code is somewhat old (files on SourceForge are from 2007) but seems to be the most simple and usable tool I have seen so fare. Cuddle makes use of Wget , provides a download queue, supports multiple downloads and allows the usage of wgets limit-rate feature....
