Hi Ruben,
Thank you for your reply. Here it is what I found out:
1- I had a cluster defined but I deleted it, so right now I don't have any.
2- The only host I have at the moment is correctly monitored. And the
output of monitor_ds.sh is correctly showing info about the datastore (I
cannot run anything else from the script because I don't have root
privileges):
DS_LOCATION_USED_MB=34417
DS_LOCATION_TOTAL_MB=32802826
DS_LOCATION_FREE_MB=18826318
However OpenNebula is not monitoring datastore 0 as it does with the others.
3- I haven't set DATASTORE_LOCATION. I have a self-contained
installation and it should default to $ONE_LOCATION/var/datastores,
which resides in a network shared partition. And yes, the datastore is
mounted.
Regards,
Javier

Hi Javier,
A couple of ideas:
1.- System DS needs to be associated to a cluster. Sometimes this may
cause problems if a host is in a cluster but the cluster hasn't got
any system DS. (This seems not to be your problem, but just double
checking)
2.- System DS information is gathered through the motorization
process. You need to check: 1.- hosts are being monitored, 2.- the
monitor message includes information about the DS. You can debug this
by executing monitor_ds.sh script at the hosts. Monitor DS is a bash
script, at the top you can find out the arguments you need to pass to it
3.- Did you set DATASTORE_LOCATION? Maybe the monitor script is not
looking at the right place. (Also could you double check that the
datastore is actually mounted?)
Hope it helps

Hello,
After a reboot my VMs started getting stuck in PENDING state.
Watching at the log files I noticed that the problem was that the
system datastore was not being correctly monitored:
onedatastore list
ID NAME SIZE AVAIL CLUSTER IMAGES TYPE DS
TM
0 system 0M - - 0 sys -
shared
1 default 31.3T 57% - 12 img fs
shared
2 files 31.3T 57% - 2 fil fs
ssh
And I was getting the following error:
Fri Jan 17 17:32:02 2014 [SCHED][D]: VM 2794: Local Datastore 0 in
Host 8 filtered out. Not enough capacity.
Now, if I create a new system datastore, it happens the same as
with datastore 0. However, creating an image datastore and then
changing its type to SYSTEM_DS makes it work fine and VMs start
being deployed again using that alternative system datastore.
My question is if this is a bug or if I am making some mistake.
Thank you,
Javier
