Re: RAID Recovery

Hi.

While I agree with Shachar about the advantages of software RAID, this is not true. All modern RAID controllers maintain a replica of their configuration on all disks. This allows easy RAID controller migration between *similar* RAID controllers.


If you ship the disks to another server using the same RAID controller (for HP servers, interoperability is available between almost all RAID controllers, but for Dell I don't know), and you insert them _at_the_original_slot_order_, there should be no problem. You will be able to Import/Activate your array and be happy with it.

One of the greatest problems with hardware raid is that you need the actual controller in order to access the disks. Sorry.

Re: RAID Recovery

Hi Ez,

Thanks, I will try it

Worst case if it doesn't work I will have them RescueCD boot and I will 
install remotely via VPN tunnel or SSH tunnel - which I don't like and not 
sure if it is possible.

persistent disk numbering

hi

i have 2 sata disks. i boot from both (one at a time of course)

when i disconnect the second, all is persistent, the first stays sda
however when i disconnect the first, the seconds changes from sdb to sda

is there a way to make it persistent ?
(something like UID= or LABEL= as is done in fstab )

The sd? names are not persistent that's why you may use either
the UUID=, LABEL= etc. or alternatively you may want to look
at:
  /dev/disk/by-label
  /dev/disk/by-uuid
  /dev/disk/by-id
  /dev/disk/by-path

Re: RAID Recovery

If it doesn't work, let them place the OS DVD in the drive, and remotely install it (unless you use Kickstart or similar methods).

You should have remote console for any modern server-class hardware.

Linux for an association I work for.

Greetings,


I need your help regarding convincing the vice president of an association to shift from MS XP to Linux. What I did till now was install Ubuntu on two machines that were phasing out and failed to run MS. We got all services we needed including connectivity to external resources.

Currently the objection to my initiation is in three items:

  1. Make Linux connect to IPVPN (thought it is straight forward).
  2. Maintenance cost.
  3. Getting his approval for my test (seems like a small man).
I need information to try to overturn his stubbornness.

Re: Linux for an association I work for.

Not to take the wind out of your sails, I would probably advise against switching to Linux for anyone who's not a Linux expert. While it took me some years to reach this conclusion, I now believe that Linux is not a viable choice for anyone who's not an advanced user. My reasons follow:
 1. Mainstream desktop environments (KDE, GNOME) have gotten slower and buggier over the years. As I bought faster hardware, KDE and GNOME seemed slower and crashed more often.
 2. Linux distributions don't work. Even Ubuntu and other mainstream distributions simply do not work. Package testing is poor, and various programs do not integrate with one another. I often find myself having to fix things manually, usually by digging deep into various scripts/configuration files. Additionally, at least with Ubuntu, upgrades tend to break horribly, requiring a clean reinstallation.
 3. Usability as a whole is becoming less viable. Applications (at least with my recent Ubuntu distrubutions) tend to crash often, work more slowly and have less features.

Windows suffers from the same problems, only it's not as slow as Linux. On the other hand, I've been using OS X lately, and the thing works. The UI is simple, relatively powerful and does not randomly crash. I'm guessing OS X is not a valid choice for you, due to the prohibitive cost of Mac hardware.

Anyway, that's what I think.

Good luck, though.

Dear Mr. Brace,

Thank you for contacting Logitech’s Electrical Support.

I understand that Quickcam Chat is not working properly with your Skype Linux.

Mr. Brace, with regards to your issue, I am sorry that we do not provide support for Linux operating system. Therefore we do not have any working software drivers for Linux as well.

You can try google for some third party Linux software drivers which might solve your green image issue.

If you have any additional questions or comments regarding your product, please feel free to visit our website at http://www.logitech.com and update this incident.

Happy a nice day!

As makers of this Webcam can you please give me assistance? I have tried

Today it worked once and once only with:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

When I typed the above into System Control Panel - Console with root password the Logitech Quickcam worked OK... However I doubt that without root the camera will work in Skype. Is there away to set Mandriva to do this without having to type this each time?
Any Ideas?

Thanking you in advance
Moshe

========================
Before:

No go with the Mandriva 2009.0 regarding the Webcam. I unfortunately don't remember what I did but for one time I actually got a picture in the Preview.

I think in the /etc/modprobe.d I added a line

"options quickcam compatible=6" as I saw in www.linuxquestions.org

I also tried both

LD_PRELOAD=/usr/lib/libv4l/v4compat.so Skype

LD_PRELOAD=/usr/lib/libv4l/v42convert.so Skype

I don't feel that way. I've been happily using KDE-3.5.x on an ageing Pentium 
4-2.4 GHz machine for quite some time now. It didn't get any slower. GNOME is 
even faster than KDE 3, but I don't like it, so I'm not using it. If you can 
get used to it, then it is a viable option, of course. KDE 4 is also OK here 
(Mandriva Cooker), but still has many warts, so I'm still using KDE 3, but 
with many KDE 4 apps.

KDE 3 itself crashes very rarely, if at all. Applications I'm running on top 
of it, crash sometimes (but not too often), but that is expected. Are you 
using proprietary video drivers by any chance? They tend to make X crash and 
hang.

Don't know about Ubuntu, and I'm using Mandriva Cooker, whose purpose is that 
users will witness the breakages before they reach the main release, so I 
cannot comment how well it suffers from this problem. But it's probably not 
worse than Windows, in case you have an expert ready. Many simpletons ("Aunt 
Tillie"'s and other) users will be perfectly happy in Linux. More so than 
Windows anyway.

Applications here on my system, don't crash often, work fast enough (I don't 
recall them being substantially slower than before) and they don't have less 
features. GUI Applications I use often are: KDE4's KMail, Firefox, XChat, 
KDE4's Kopete, gvim, KDE 4's Kate, and Amarok 1.x.
