[03:08] <pabs_> ok whos ready for an easy noob question :/
[03:08] <pabs_> how do i start blackbox from the command prompt?
[03:50] <pabs_> ok i figured it out lol....
[03:50] <pabs_> now i just need to get a terminal in blackbox
[03:50] <pabs_> :|
[08:26] <ealden> MarioMeyer: ping
[03:34] <visik7> why evms are started at boot ?
[03:34] <fabbione> because if you use evms you need it
[03:34] <fabbione> and the script doesn't really do much itseld
[03:34] <fabbione> itself
[03:36] <visik7> but there is no evms install options
[03:37] <fabbione> so? you can install use it later on. evms can take over lvm2 disks for example
[03:37] <visik7> ah
[03:37] <visik7> is there some guide about lvm/evms
[03:37] <fabbione> and you don't need to worry about installing the package if you start using it
[03:37] <fabbione> not that i know of
[03:38] <visik7> do u use lvm ?
[03:38] <fabbione> i am not familiar with evms myself
[03:38] <spike> eheeh, seems I'm not the only one complaining about it being there :P
[03:38] <visik7> and lvm ?
[03:38] <fabbione> i prefer lvm2 but that's a personal choise
[03:38] <visik7> I can't get the differences between lvm and evms
[03:38] <fabbione> they both do similar things
[03:38] <spike> visik7: userland tools
[03:38] <fabbione> they just get to it in different ways
[03:38] <spike> that's the only diff
[03:38] <fabbione> spike: not only
[03:38] <spike> not even that different afaik
[03:39] <fabbione> they configure the device-mapper in differnt ways
[03:39] <fabbione> evms has also the concept of raid iirc
[03:43] <spike> brb
[04:13] <visik7> fabbione: I have an external disk how can I snapshot the current system that is an ubuntu installed with lvm ?
[04:14] <fabbione> visik7: snapshot as in an lvm snapshot or a backup?
[04:14] <fabbione> because the 2 are completely different things
[04:14] <visik7> ah
[04:14] <visik7> maybe I misunderstood something
[04:14] <visik7> a copy of therunning system to restore in case of emergence
[04:15] <visik7> so yes probably a backup
[04:17] <fabbione> it's a backup
[04:17] <fabbione> but
[04:17] <fabbione> you can achieve backup via lvm snapshot
[04:17] <fabbione> the question is that with an external drive i assume you want a normal backup
[04:18] <fabbione> because playing with lvm snapshot can be tricky if you don't understand lvm
[04:18] <visik7> so if a lvm snapshot isn't a backup what is it ?
[04:19] <fabbione> visik7: it can be used as backup, but not on an external disk that you plug/unplug
[04:19] <visik7> it must be connected from the boot ?
[04:19] <fabbione> yes
[04:19] <fabbione> and you can't unplug it
[04:20] <fabbione> lvm snapshots record deltas of metadata
[04:20] <fabbione> not the entire thingy
[04:20] <fabbione> metadata and data sorry
[04:20] <visik7> yes I understand the problem
[04:20] <visik7> so
[04:20] <fabbione> example:
[04:20] <visik7> to backup using lvm the way is ?...
[04:20] <fabbione> you have your /foo on lvm
[04:21] <fabbione> and there is a file called bar
[04:21] <visik7> a kind of cow
[04:21] <fabbione> i make a snapshot of that
[04:21] <fabbione> mount the snapshot somewhere
[04:21] <fabbione> and create a file called bar
[04:21] <fabbione> baz sorry
[04:21] <fabbione> baz will appear only on the snapshot
[04:21] <fabbione> file bar is in both
[04:21] <visik7> mmm
[04:22] <fabbione> but it stored on the real system only once
[04:22] <visik7> so is not what I need
[04:22] <fabbione> you want a normal backup
[04:22] <fabbione> specially if you don't know lvm concept of snapshot
[04:22] <fabbione> that again.. can be used as backup if you know what you are doing
[04:24] <visik7> it's the root partition so it's complicate to snapshot as backup
[04:24] <visik7> I've to reboot
[04:24] <fabbione> iirc snapshot can be done live
[04:24] <fabbione> check the man page
[04:25] <fabbione> it's explained
[04:26] <visik7> which of 40 commands related to lvm ?
[04:26] <fabbione> man lvm
[04:27] <visik7> yes there's a short explaination and then a SEE ALSO section of 40 commands
[04:27] <fabbione> the 40 commands are all symlinks to lvm binaries just to help users understsand what they are doing
[04:27] <visik7> ah
[04:27] <visik7> :)
[04:27] <visik7> I think it's more complicated than a single blinary
[04:30] <visik7> is there some references on ubuntu wiki ?
[04:31] <fabbione> visik7: check lvm documentation in /usr/share/doc/lvm2
[04:32] <fabbione> visik7: these anyway are really basic questions you can ask in #ubuntu
[04:32] <visik7> ok
[09:15] <MarioMeyer> ealden_, ping
[09:32] <ubijtsa> hohum...
