<div style="font-family:arial,sans-serif;font-size:12px"><br></div><div style="font-family:arial,sans-serif;font-size:12px">This can be solved by either using a better way to compute the image size (e.g. qemu-img) or recomputing the size after saving back the image.</div>

<br>
I am using OpenNebula 3.8.1 with OpenVZ hypervisor support enabled. I noticed that the value of the corresponding persistent image parameter is not changed even if actual size of the file has changed.<br>
<br>
$ oneimage list|grep persistent<br>
ID USER GROUP NAME DATASTORE SIZE TYPE PER STAT RVMS<br>
4 oneadmin oneadmin test persistent default 172M OS Yes used 1<br>
<br>
$ oneimage show 4|egrep "SOURCE|PATH|SIZE"<br>
SOURCE : /var/lib/one/datastores/1/<u></u>6900190977e9afc6d9290b8aef16f7<u></u>68<br>
PATH : /var/lib/one/datastores/1/<u></u>2b0ad99f99eaa99458769eb53951b6<u></u>85<br>
SIZE : 172M<br>
<br>
The image with ID 4 was created as clone of the image with ID 1 by 'oneimage clone' command. The image with ID 1 has a size 172MB:<br>
$ oneimage show 1|egrep "SOURCE|PATH|SIZE"<br>
SOURCE : /var/lib/one/datastores/1/<u></u>2b0ad99f99eaa99458769eb53951b6<u></u>85<br>
PATH : /tmp/sl-6-x86_64.tar.gz<br>
SIZE : 172M<br>
<br>
and that corresponds to its real size on the file system:<br>
$ ll -h /var/lib/one/datastores/1/<u></u>2b0ad99f99eaa99458769eb53951b6<u></u>85<br>
-rw-rw---- 1 oneadmin oneadmin 172M Oct 3 17:51 /var/lib/one/datastores/1/<u></u>2b0ad99f99eaa99458769eb53951b6<u></u>85<br>
<br>
The real size of modified and saved persistent image with ID 4 has changed on FS:<br>
$ ll -h /var/lib/one/datastores/1/<u></u>6900190977e9afc6d9290b8aef16f7<u></u>68<br>
-rw-rw---- 1 oneadmin oneadmin 181M Nov 16 15:41 /var/lib/one/datastores/1/<u></u>6900190977e9afc6d9290b8aef16f7<u></u>68<br>
<br>
but 'oneimage list' and 'oneimage show' still show the same size equals to the size of initial image with ID 1:<br>
$ oneimage list|egrep "^ 1|4"<br>
1 oneadmin oneadmin SL 6.3 x86_64 default 172M OS No rdy 0<br>
4 oneadmin oneadmin test persistent default 172M OS Yes used 1<br>
<br>
So I wonder if someone observes the same behavior and someone does then if it is bug?<br>
<br>
Regards,<br>
Nikolay.<br>
