Subject Re: Strange size of template from snapshot on XenServer
Date Thu, 02 Nov 2017 05:30:39 GMT
Hi Lotic,

Can you try with any release between 4.6 to 4.8 and see if this bug is there?

Basically, any release which contains commit 2c4ea503f92bcf9c611f409d5cdecb42b0115b69 and
missing commit 8a3fd10.

    Rafael, I know and appreciate your help :)
    
    I recognize all effort of CloudStack community.
    I think all admins use snapshot to backup your virtual disks, I think it is not a isolated
problem. Imagine a crash on your storage and you need convert your snapshots to templates.
    
    Thanks 
    Marcelo

    Well, I could not reproduce the problem in ACS 4.9.2.0. So, before fixing anything, the
person that might take on this should first find the root of the problem.
    
    I understand what you are saying that it is a critical problem, but you have to understand
that this is an open-source and free software.
    
    Having said that, ALL of my work here has been pro-bono; even though I am a committer
and PMC, I am not willing to dive deeper into this issue now as it does not affect me. It
does not mean that I would not help people if I have time, as you can notice whenever I have
some free time I try to be around and guide or check things for other people in this list.
    
    If this is a huge problem for you right now, I suggest you looking for companies that
provide enterprise support for ACS.
