• Cant access ephemeral storage on Amazon ubuntu instance

  I want to utilise my ephemeral storage as mentioned in this question but I seem to be falling at the first hurdle.

• sysctl.conf ignore net settings

  - by Steffen Unland

  I have a little problem with sysctl on a Ubuntu 10.04 LTS system. When I set the sysctl values with "sysctl -w " all work fine, but when I try to use the sysctl.conf file. the net settings will be ignored. For example my sysctl.conf # /etc/sysctl.conf - Configuration file for setting system variables kernel.domainname=findme.sysctl # Corefiles information fs.suid_dumpable=2 kernel.core_pattern=/cores/core-%e-%s-%u-%g-%p-%t ##############################################################3 # Functions previously found in netbase net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait=1 net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait=1 when I grep to the values, I can see that the sysctl settings for net.ipv4.netfilter don't set. [host:~ ] $ sysctl -a | grep domainname kernel.domainname = findme.sysctl [host:~ ] $ sysctl -a | grep "core_pattern" kernel.core_pattern = /cores/core-%e-%s-%u-%g-%p-%t [host:~ ] $ sysctl -a | grep "timeout_fin_wait" net.netfilter.nf_conntrack_tcp_timeout_fin_wait = 120 net.ipv4.netfilter.ip_conntrack_tcp_timeout_fin_wait = 120 [host:~ ] $ sysctl -a | grep "timeout_close_wait" net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60 net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait = 60 can somebody help me to solve the problem? If you need more information I can post it. Cheers, Steffen

• How does btrfs RAID work in degraded mode?

  - by turbo

  My idea was that (using loopback devices) it works like this Create the raid array sudo mkfs.btrfs -m raid1 -d raid1 /dev/loop1 /dev/loop2 You mount them sudo mount /dev/loop1 /mnt and mark them touch goodcondition You unmount and simulate disk failure (remove disk or delete loopback device loop2 in my case) You mount degraded -o degraded and mark again touch degraded You add the bad disk again sudo btrfs dev add /dev/loop2 You rebalance sudo btrfs fi ba /mnt And Raid 1 should work again. But that's not the case. sudo btrfs fi show: Total devices 3 FS bytes used 28.00KB devid 3 size 4.00GB used 264.00MB path /dev/loop1 devid 2 size 4.00GB used 272.00MB path /dev/loop2 *** Some devices missing The file degraded lives on loop1 but not on loop2 when loop2 is mounted in degraded mode. Why is that?

• Yippy &ndash; the F# MVVM Pattern

  - by MarkPearl

  I did a recent post on implementing WPF with F#. Today I would like to expand on this posting to give a simple implementation of the MVVM pattern in F#. A good read about this topic can also be found on Dean Chalk’s blog although my example of the pattern is possibly simpler. With the MVVM pattern one typically has 3 segments, the view, viewmodel and model. With the beauty of WPF binding one is able to link the state based viewmodel to the view. In my implementation I have kept the same principles. I have a view (MainView.xaml), and and a ViewModel (MainViewModel.fs).     What I would really like to illustrate in this posting is the binding between the View and the ViewModel so I am going to jump to that… In Program.fs I have the following code… module Program open System open System.Windows open System.Windows.Controls open System.Windows.Markup open myViewModels // Create the View and bind it to the View Model let myView = Application.LoadComponent(new System.Uri("/FSharpWPF;component/MainView.xaml", System.UriKind.Relative)) :?> Window myView.DataContext <- new MainViewModel() :> obj // Application Entry point [<STAThread>] [<EntryPoint>] let main(_) = (new Application()).Run(myView) You can see that I have simply created the view (myView) and then created an instance of my viewmodel (MainViewModel) and then bound it to the data context with the code… myView.DataContext <- new MainViewModel() :> obj If I have a look at my viewmodel (MainViewModel) it looks like this… module myViewModels open System open System.Windows open System.Windows.Input open System.ComponentModel open ViewModelBase type MainViewModel() = // private variables let mutable _title = "Bound Data to Textbox" // public properties member x.Title with get() = _title and set(v) = _title <- v // public commands member x.MyCommand = new FuncCommand ( (fun d -> true), (fun e -> x.ShowMessage) ) // public methods member public x.ShowMessage = let msg = MessageBox.Show(x.Title) () I have exposed a few things, namely a property called Title that is mutable, a command and a method called ShowMessage that simply pops up a message box when called. If I then look at my view which I have created in xaml (MainView.xaml) it looks as follows… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF MVVM" Height="350" Width="525"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <TextBox Text="{Binding Path=Title, Mode=TwoWay}" Grid.Row="0"/> <Button Command="{Binding MyCommand}" Grid.Row="1"> <TextBlock Text="Click Me"/> </Button> </Grid> </Window>   It is also very simple. It has a button that’s command is bound to the MyCommand and a textbox that has its text bound to the Title property. One other module that I have created is my ViewModelBase. Right now it is used to store my commanding function but I would look to expand on it at a later stage to implement other commonly used functions… module ViewModelBase open System open System.Windows open System.Windows.Input open System.ComponentModel type FuncCommand (canExec:(obj -> bool),doExec:(obj -> unit)) = let cecEvent = new DelegateEvent<EventHandler>() interface ICommand with [<CLIEvent>] member x.CanExecuteChanged = cecEvent.Publish member x.CanExecute arg = canExec(arg) member x.Execute arg = doExec(arg) Put this all together and you have a basic project that implements the MVVM pattern in F#. For me this is quite exciting as it turned out to be a lot simpler to do than I originally thought possible. Also because I have my view in XAML I can use the XAML designer to design forms in F# which I believe is a much cleaner way to go rather than implementing it all in code. Finally if I look at my viewmodel code, it is actually quite clean and compact…

• Unable to mount 1TB USB external HDD - Error

  - by superbDeveloper

  Hi, I'm getting an error when I plug in my 1TB USB external HDD, the wierd thing about this is that it was working fine before and I've been using it for about a couple of months now. yesterday I compressed one of the folders which had about 120GB of data but the compression failed after an hour and I decided to unmount the drive and shut everything down. Today when I tried to plug in the drive I got the following error: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so output of cat /proc/partitions below muzikayise@muzikayise-supercom:~$ sudo fdisk -l /dev/sdc Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x39dcba64 Device Boot Start End Blocks Id System please will someone kindly assist with this? thanks in advance,

• How can I repair a corrupt kernel if no others are installed?

  - by Willi Ballenthin

  I've been running Ubuntu 10.04 on my laptop for quite some time. When I went to boot it up this morning, BAM! kernel panic (which immediately lead to human panic) when loading the kernel. So I've spent much of the day troubleshooting, and my current theory is that the FS is fine, but that the kernel image may be corrupt. Let's go with this current theory for the sake of this question, as I am interested how it is done. How can I replace the kernel image if I have no bootable kernels? Can I boot to a 10.04 live CD, copy the the vmlinuz-2.6.3x... to the HD and go from there? Wouldn't I want to copy the initramfs as well, but configured for the desktop system? Can I generate this from the live CD?

• Is it possible to auto-mount sshfs

  - by Mark D

  Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

Now I'm trying to install it using the live cd: This is my sudo fdisk -l: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x6af447e6 Device Boot Start End Blocks Id System /dev/sda1 * 2048 781459455 390728704 7 HPFS/NTFS/exFAT /dev/sda2 781459456 789272575 3906560 82 Linux swap / Solaris /dev/sda3 789272576 976773119 93750272 83 Linux After mounting and chroot the linux partiton, I give grub-install /dev/sda command, and I get: /usr/sbin/grub-setup: error: hd0 appears to contain a iso9660 filesystem which isn't known to reserve space for DOS-style boot. Installing GRUB there could result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup (--skip-fs-probe disables this check, use at your own risk). (same error even with grub-install --recheck /dev/sda) What can I do? I also tried boot-repair, but I get this error: http://paste.ubuntu.com/1069353/

• Resize hard drive partition to make more space for /var

  - by user3357381

  I am running out of space in the /var partition. I have plenty of space in my /home partition. How do I shrink the /home partition to make more space for the /var partition? I have read some blogs that say to use the GParted Live CD. As a new user, I'm not quite sure if this is the ideal route. What is the best way to create more space for /var ? Output of df -h : Filesystem Size Used Avail Use% Mounted on /dev/sda2 19G 7.1G 11G 41% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 7.9G 8.0K 7.9G 1% /dev tmpfs 1.6G 1.5M 1.6G 1% /run none 5.0M 0 5.0M 0% /run/lock none 7.9G 624K 7.9G 1% /run/shm none 100M 60K 100M 1% /run/user /dev/sda4 454M 75M 352M 18% /boot /dev/sda5 2.3G 2.1G 36M 99% /var /dev/sda3 178G 1.3G 168G 1% /home /dev/sda6 2.8G 5.8M 2.6G 1% /tmp /dev/sdb1 3.7T 401G 3.3T 11% /hdd

• Ubuntu VM cannot start after Kernel upgrade

  - by AAz

  Several Ubuntu 10.04 VMs were restarted after few months and began getting "Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" message. Restoring those VMs from backup (to the "paused" state) allows to boot normally. However restarting the VM again results in the mentioned error message. I suspect it's the updated kernel version (2.6.32-37-server, 2.6.32-38-server) that misbehave - another Ubuntu VM (that's used as template for those failing VMs) still has 2.6.32-24-server and reboots fine. We're using HyperV (2008R2) as the server host. Nothing were changed in it's configuration. Has anyone faced this issue, please advise the solution. Many Thanks in advance!
