Hi all.,
Previous to my last two emails, I thought I'd update you and ask for a
bit of feedback.
My orginal email asked if anyone knew whether it was possible to
backup and restore solaris2.6 images created via flarcreate and
restored via a jumpstart webflash archive on a solaris 8 box.
Well, I successfully managed to build a jumpstart server (sol8) with
flash image capability, recover the images after using Gbit ethernet
point to point, and copying the flarcreate script to the 2.6 box,
creating a 26Gb flar image(via a local nfs mount), which we usually
store on a dds3/4 tape using ufsdump/ufsrestore.
However, our usual tape resore takes just over two hours from a home
rolled restore cd from which we boot.
The restored flar image from jumpstart takes over two hours also,
however I would have expected it to be quicker as I'm using Gbit
ethernet.
Has anyone had any experiences with restores from flar images which
take roughtly the same ammount of time from tape? I've been
enlightened that you cannot use compressed flash archives as they are
purely for storage purposes.
I was really looking to save time when creating and restoring flar
(FRU's as sun call them) images using jumpstart, but I'm a little
bemused as to why this is so.... I had applied the 2Gb patch for
restoring flar images and have a working system from which I created
my 26Gb image. (a mix of OS data, applications and user data)
It takes 2hrs 43 minutes to work out and create my flar image over a
Gbit net, as I also believe that roughly 40% of this time is spent
working out how large the image is going to be. Some editing of the
script and adding in timing debug which I added in and created a flar
archive of my jumpstart server to work this out.
Has anyone else experienced similar behaviour?
Feedback is most definitely appreciated. I shall summarise..
Regards
dan.
