[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-API] The vdi is not available
I actually just took a look and in the the servers where everything is working
correctly everything is under
/var/run/sr-mount/9f9aa794-86c0-9c36-a99d-1e5fdc14a206/
and on the one that complains that it cant find the file, the file is actually
located in
/var/run/sr-mount/9f9aa794-86c0-9c36-a99d-1e5fdc14a206/9f9aa794-86c0-9c36-a99d-1e5fdc14a206/
it's as if it is mounting the storage repository within itself.
how can i check if thin provisioning is enabled?

there is something wrong. It looks it tries to open a .raw file instead
of .vhd.
Maybe one of your server has been installed selecting the "thin
provisionning" feature and the others servers not ?
As far as I know thin provisioning uses vhd, non thin provisioning uses raw.
So if you have mixed installations that will not work when using a
shared storage between them.
My guess is that if you create VM on one server it will create a .vhd
image, and on the other a .raw image.
I can't be 100% certain as I've always used thin provisionning.
You maybe can check if you have mixed raw/vhd in
/var/run/sr-mount/9f9aa794-86c0-9c36-a99d-1e5fdc14a206/
