    [all variants] Re: Two RAID1 questions

    Okay, thanks; understood (so if one copy gets 'corrupted', the other will too and that's why the need to have a known working backup)

    I am hoping someone will throw light on the 2nd query as...

    [all variants] Two RAID1 questions

    1. How is RAID1 different from a backup copy updated constantly? I am asking this in the context of various comments I encountered in different forums by people saying that RAID is not backup and...
  3. [lubuntu] RAID1 (linux softraid using mdadm), data lost in disk with data when added to RAID1

    I had two disks with dedicated data partitions which were kept in sync using periodic rsync (not RAID). One of the disks failed. I bought a new disk and decided to switch to RAID1 instead of using...

    [ubuntu_studio] Re: No sound except in xbmc

    What's interesting is there are no system sounds (though I could not find setting for that anywhere). Applications like Virtual MIDI keyboard do not produce any sound either.

    That said, I did...

    [ubuntu_studio] No sound except in xbmc

    I have two users configured on my computer. For one of them, there is no sound. The other one I only use for XBMC in fullscreen mode and XBMC plays the music just fine.

    Ubuntu Studio 12.04.
  7. [all variants] Re: 64-bit kernel panics if memory remap enabled in BIOS

    I would have done that compromise (actually wanted to use the SATA RAID option, not AHCI, but the computer fails with RAID too, same/similar error), except for the fact that with IDE, the computer...
  8. [all variants] Re: 64-bit kernel panics if memory remap enabled in BIOS

    Made some progress. It could be the SATA controller. The SATA controller has 3 modes: AHCI, IDE and RAID. For modes other than IDE, Ubuntu boot-up fails with kernel panic when memory remapping is...
  9. [all variants] Re: Bonding (link aggregation) and/or bridging makes bridged mode in VMs unusable

    Added isc-dhcp-relay, now getting DHCP allocations, but contrary to what I thought, that does not result in success in getting internet connectivity from the guest! However, isc-dhcp-relay and...
  10. [all variants] Re: 64-bit kernel panics if memory remap enabled in BIOS

    ATI Radeon HD 5450.

    Time to switch back to Ubuntu default non-proprietary driver?

    [update] Uninstalled proprietary ATI fglrx driver to no avail. The problems remain. If I set the memory...
  11. [all variants] Bonding (link aggregation) and/or bridging makes bridged mode in VMs unusable

    This is about VMs created using VirtualBox and libvirtd (virtual-machine-manager)

    I have wireless wlan0 interface bonded to wired eth0 interface. wlan0 interface is the active interface - the...

    The output is as expected:

  13. [all variants] Bonding (link aggregation) with wireless roaming, how should I set this up?

    How to configure the bonding to work with wireless roaming as well?

    wpa_action is used to control roaming with list of networks defined in the wpa_supplicant configuration file. wlan0 interface...
  14. [ubuntu] Re: bond0 using wlan0 and eth0 with ifplugd, hangs on system shutdown

    Update: Since switching to Ubuntu Studio, I no longer have the problem of unstable (frozen) shutdowns: well, either switching to Ubuntu Studio OR not using ifplugd anymore did that.
  15. [all variants] Re: 64-bit kernel panics if memory remap enabled in BIOS

    I shall try your script later tonight.

    memtest offers so many options! it ran fine with the default options selected and remapping enabled in BIOS. But it fails when I select some of the options...

    [ubuntu] Re: partrouted tap device and virt-manager

    I know this is way too old and you would have arrived at a few ways of achieving this, but the simplest thing which comes to mind is: if libvirt is expecting a bridge interface, well create one in...
  17. [all variants] Re: 64-bit kernel panics if memory remap enabled in BIOS

    I installed 64-bit because 32-bit OS was not using the full 6 GB...(the latest ubuntu 12.04 that is). Specifically, I used ubuntu business remix 12.04 32-bit.

    Ubuntu, Ubuntu Studio, Xubuntu all...
  18. [all variants] 64-bit kernel panics if memory remap enabled in BIOS

    I have total 6 GB of RAM installed.

    Ubuntu 12.04 64-bit flavours refuse to install with a kernel panic indicating hardware failure if I enable memory remap in BIOS (which led me to change the...
  19. [ubuntu] Re: bond0 using wlan0 and eth0 with ifplugd, hangs on system shutdown

    Is it useless to have both bond0 and ifplugd running simultaneously since, in the configuration above, both end up doing the same thing anyway. Could having both be the reason for the instability at...
  20. [ubuntu] 9p (Plan 9) shares using libvirt - random garbage returned

    I have a host folder containing photos shared across to my guest vm configured using libvirt (virt-manager).

  21. [ubuntu] Getting Network Manager applet to show status of interfaces defined in interfaces

    Is it possible to let the configuration reside in /etc/network/interfaces, but then use some sort of GUI indicator to show the network status?

    I am not sure if Network Manager can deal with...
  22. [ubuntu] VirtualBox - using existing bonded connection for networking

    I have bonding set up with wlan0 and eth0 as members. This works okay in the sense that I can connect to the internet successfully.

    I now wish to setup VirtualBox VM such that internet...
  23. [ubuntu] bond0 using wlan0 and eth0 with ifplugd, hangs on system shutdown

    I have bonded wireless and ethernet together in fallback mode, so that only one IP address is used for both (so my port-forwards from router to a given IP address continue to work irrespective of...

    It is a file, but I want to use tail -f so I can see updates happening in real-time - the main purpose is to view live log. Using...
