[gentoo-user] KDE plasmoids/widgets collapsing on the floor?
I have no idea what is causing this. This is a new installation with a KDE desktop. The PC has two monitors and was set up to have different widgets in each desktop - this was necessary with the current KDE version to be able to have different wallpapers for each virtual desktop. Only the first virtual desktop has widgets (plasmoids). The left monitor is connected to the PC with DVI, the right monitor with HDMI. No monitor is set as the primary monitor, but I have also tried it with the left being the primary monitor. All desktop widgets are locked so they don't move around. Every time the user logs out/in all widgets in the left hand monitor have moved/dropped from the top of the *left* screen only to the bottom and overlap each other. The right screen behaves as it should. When the user reboots, rather than logout/in the widgets stay in their assigned positions on the left desktop. :-/ I am not sure why this happens. Why it happens in the left monitor only (DVI connector). Why they fall all the way to the bottom behind the KDE toolbar. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

ZFS apparently can do such things --- yet what's the difference in performance of ZFS compared to hardware raid? Software raid with MD makes for quite a slowdown. Well, there is certainly no reason that you couldn't serialize a logical volume as far as design goes. It just isn't implemented (as far as I'm aware), though you certainly can just dd the contents of a logical volume. You can use dd to make a copy. Then what do you do with this copy? I suppose you can't just use dd to write the copy into another volume group and have it show up as desired. You might destroy the volume group instead ... You can dd from a logical volume into a file, and from a file into a logical volume. You won't destroy the volume group unless you do something dumb like trying to copy it directly onto a physical volume. Logical volumes are just block devices as far as the kernel is concerned. You mean I need to create a LV (of the same size) and then use dd to write the backup into it? That doesn't seem like a safe method. How about ZFS as root file system? I'd rather create a pool over all the disks and create file systems within the pool than use something like ext4 to get the system to boot. I doubt zfs is supported by grub and such, so you'd have to do the usual in-betweens as you're eluding to. However, I suspect it would generally work. I haven't really used zfs personally other than tinkering around a bit in a VM. That would be a very big disadvantage. When you use zfs, it doesn't really make sense to have extra partitions or drives; you just want to create a pool from all drives and use that. Even if you accept a boot partition, that partition must be on a raid volume, so you either have to dedicate at least two disks to it, or you're employing software raid for a very small partition and cannot use the whole device for ZFS as recommended. That just sucks. And how do I convert a system installed on an ext4 FS (on a hardware raid-1) to ZFS? I can plug in another two disks, create a ZFS pool from them, make file systems (like for /tmp, /var, /usr ...) and copy everything over. But how do I make it bootable? I'm pretty sure you'd need an initramfs and a boot partition that is readable by the bootloader. You can skip that with btrfs, but not with zfs. GRUB is FSF so I doubt they'll be doing anything about zfs anytime soon. Otherwise, you'll have to copy everything over - btrfs can do in-place ext4 conversion, but not zfs. Well, I don't want to use btrfs (yet). The raid capabilities of brtfs are probably one of its most unstable features. They are derived from mdraid: Can they compete with ZFS both in performance and, more important, reliability?

In reality you create just the directories you need. Global stuff goes in the top level (like inventory). Variables for groups and individual hosts go into suitably named files inside group_vars and host_vars. Roles have a definite structure, in practice you'll use tasks/ and templates/ a lot, everything else only when you need them. This is a good design I feel. If a file describes variables, you don't have to tag it as such or explicitly include it anywhere. Instead, files inside a *vars/ directory contain variables, the system knows when to use them based on the name of the file. It's really stunningly obvious once you train your brain to stop thinking in terms of complexity :-) Thanks a lot ... I spent some time with it already and learn to like it ;) I am nearly done with setting up an inventory file for all the customer boxes I am responsible for. Just using the ad-hoc-commands is very useful already! For example I could store the output of the setup module for local reference ... this gives me loads of basic information. I know it is not a backup program but I think I could also use it to rsync all the /etc directories to my ansible host? Or trigger a git push on the remote machines to let them push their configs up to some central git-repo I provide here (having /etc and the @world-file is quite a good start here and then ... ). It is also great to be able to check for let's say shellshock-vulnerability by adding a playbook and running it to all/some of the servers out there ... I am really starting to come up with lots of ideas! My current use case will be more of an inventory to track all the boxes ... deploying stuff out to them seems not so easy in my slightly heterogeneous zoo. But this can lead to a more standardized setup, sure. One question: As far as I see the hostname in the inventory does not have to be unique? I have some firewalls out there without a proper FQDN, so there are several pfsense lines in various groups (I have now groups in there with the name of the [customer] and some of them have child groups like [customer-sambas] ...). I would like to be able to also access all the ipfires or sambas in another group ... so I would have to list them again in that group [ipfires] ? Thanks for the great hint to ansible, looking great so far! Stefan Ansible is a not a backup solution. You don't need to download your /etc from the machines because you deploy your /etc to machines via ansible. I was also thinking about putting /etc in git and then deploying it but: - on updates, will you update all configurations in all /etc repos? - do you really want to keep all the information in git, is it necessary? Opposite to this, you can define roles like apache, mysql, common-gentoo, firewall etc. where you describe how to install that software and do some basic configuration that is to be shared among the most of your machines. You can also define default values (like the bind address, the listen port) and then override it in your machine group role (if it's used with multiple servers). If you have all the software pieces written down in roles and you use the defaults of that role, you simply get to that a server configuration is just a compound of that roles (plus some configuration copy). Like this an apache+php application server with firewall and centralized logging is just like around 20-30 lines. You don't need to use roles, you can put all this information in task files and then you include this files, however then you don't have encapsulation and the default values. It really doesn't matter how your servers diverge, if you keep the details split up in roles, you just cherry-pick the roles, overriding their defaults and copying configuration. However it is true that ansible tries to keep your configuration identical among server (for example to not install apache absolutely differently on two machines, but to use as much common pieces as possible). Check out ansible galaxy and search for some roles (like apache, cron, redis etc.). Regarding configuration, you can template or just copy the configuration to a server (like when installing postfix for example) but you need to keep the template up to date with the shipped configuration (or ship your own configuration and diverge from mainstream). An alternative is to just make some changes to the default configuration (replace line, add some line). Then you don't need to update your templates, on updates you can copy over the new configuration from ._cfgXXX and make the same changes as before, most probably it will work. A good trick is to use include directories where possible (don't edit /etc/sudoers but copy your

I can't say whether any code from mdraid was borrowed but btrfs raid works completely differently and has about as much in common with mdraid as zfs does. I can't speak for zfs performance, but btrfs performance isn't all that great right now - I don't think there is any theoretical reason why it couldn't be as good as zfs one day, but it isn't today. Btrfs is certainly far less reliable than zfs on solaris - zfs on linux has less long-term history of any kind but most seem to think it works reasonably well. With ZFS at hand, btrfs seems pretty obsolete. You do realize that btrfs was created when ZFS was already at hand, right? I don't think that ZFS will be likely to make btrfs obsolete unless it adopts more dynamic desktop-oriented features (like being able to modify a vdev), and is relicensed to something GPL-compatible. Unless those happen, it is unlikely that btrfs is going to go away, unless it is replaced by something different. -- Rich

[gentoo-user] Is it wrong to install a specific version
Hi. I wanted to install plasma 5 on my laptop, but I encountered a lot of problems regarding dependencies, masking and other stuff. Since I felt a little stubbornness in myself, and didn't want to back off ! I took another approach. I checked that what packages will be installed. After that I removed the qt4 and installed all of the required qt5 packages from qt-5.4.0 one by one and using the specific version. After that I did the same with qt-framework packages and so on. I think that this is generally a bad idea, because the it makes the World set much bigger. However I am wondering what will happen when the tree updates? I mean for examples when another version of qt5 comes out, portage will try to update it ? thanks.

I think you can edit the world file and make the qt packages look something like this: dev-qt/qtcore:5 Basically, remove the specific version and just tell it you want the 5 slot. Then when something new comes out, it should upgrade. Of course, those versions will either have to be stable or in the needed keyword/unmask file. Just a thought.
