[Users] Failed to growing Ploop CT < 1G.

[Carlos Pina]

Hi,

 

I'm testing debian compiled kernel 2.6.32-openvz-042stab082.6-amd64

 

2.6.32-openvz-042stab082.6-amd64

libploop1:amd64  1.9-2

poop 1.9-2

vzctl 4.5-5wt1

vzquota   3.1-1

vzstats 0.5.2-1

 

Once I created a CT in ploop layout mode with --diskspace <=1026m , 

then I can't resize de ploop image to size greater than initial size of
1026.

 

Otherwise, if I create it with diskspace greater than 1026 then It works
perfectly.

 

 

Is It a bug?

 

See above:
