Jumping from FC10 to FC11

Finally I had enough spare time to sit down and carefully upgrade my VPS to Fedora Core 11 using the recommendations to steer clear of any possible issues. Needless to say everything went without a hitch. The only thing that should be redone is clamav which I setup in hast but that’s trivial.

MPxIO unveiled

Another must see video has been published on Sun Video Blog and this time it’s all about MPxIO. So if you been looking for in-depth explanation of how things work from multipathing perspective in Solaris you’re more than welcome to follow to this link.
I decided to embed the videos into this post just in case if the above link goes down.

Sun – HTTP/1.1 301 Moved Permanently

As you certainly know Sun Microsystems Co. doesn’t exist anylonger and now it’s just another part of our history. So it’s not a surprise to see that all requests to www.sun.com are now redirected to a new home place www.oracle.com

Btw, I encourage you to watch Larry Ellison speaking about the future steps that Oracle is planing to make not only because it’s cognitive but because it also might affect you directly. Oracle is focusing on direct sales and thinking about uncoupling 4,000 top customers from their current partners unless you’re not a VAP (Value Added Partner).

Let all of us be prepared for the changes and don’t forget that every cloud has a silver lining.

iPad that iFails

Don’t know how you feel, but my opinion is that newly introduced Apple device, called iPad, is at the very least… ugh… strange… controversial… questionable… but certainly not what most of us have been awaiting for. I’m scratching my head trying to imagine a reasonable usage-case for such a device but constantly failing. To add a simple corollary: this ipod/iphone on steroids is definitely out of my personal interest and as far as I can tell, from reading other peoples’ blogs and forum posts, I’m not the only one.

Mending VxVM

Last night I was upgrading a domain on our SF6900 box to Solaris 10 and since we use VxVM to mirror our root disk there was no use in preparing dedicated backup neither on tape nor on separate disk because it’s much easier and accurate to split rootdg into two disk groups, e.g. rootdg and rootdgold, and later import rootdgold, i.e. our saved copy of rootdg, to restore every single file. But when I tried to start the volumes it only revealed that not everything went off smoothly:

# vxvol -g rootdgold startall
VxVM vxvol ERROR V-5-1-11804 Volume coredump is empty and cannot be started
VxVM vxvol ERROR V-5-1-11804 Volume oem_home is empty and cannot be started
VxVM vxvol ERROR V-5-1-11804 Volume var is empty and cannot be started
VxVM vxvol ERROR V-5-1-11804 Volume rootvol is empty and cannot be started
VxVM vxvol ERROR V-5-1-11804 Volume swapvol is empty and cannot be started

Looking at the volumes I found that all of them were really in EMPTY state:

# vxprint -g rootdgold -v
v  coredump     fsgen        DISABLED 62918208 -        EMPTY    -       -
v  oem_home     fsgen        DISABLED 4202688  -        EMPTY    -       -
v  rootvol      root         DISABLED 8395200  -        EMPTY    -       -
v  swapvol      swap         DISABLED 50330496 -        EMPTY    -       -
v  var          fsgen        DISABLED 8395200  -        EMPTY    -       -

Actually, not much should be done to overcome this situation. You could use both “vxvol init clean” or “vxmend fix clean” as a remedy to set the state for the named plex to CLEAN:

# vxmend -g rootdgold fix clean rootvol-02
# vxmend -g rootdgold fix clean coredump-02
# vxmend -g rootdgold fix clean oem_home-02
# vxmend -g rootdgold fix clean var-02
# vxmend -g rootdgold fix clean swap-02

Once that has been done I started the volume and successfully mounted it.

# vxvol -g rootdgold startall

Green light for Oracle’s deal over Sun Microsystems


The European Commission has approved under the EU Merger Regulation the proposed acquisition of US hardware and software vendor Sun Microsystems Inc. by Oracle Corporation, a US enterprise software company. After an in-depth examination, launched in September 2009 (see IP/09/1271 ), the Commission concluded that the transaction would not significantly impede effective competition in the European Economic Area (EEA) or any substantial part of it.
