Hi,
The low disk space is controlled by a parameter in the engine called FreeSpaceCriticalLowInGB, and can be configured using the cli tool engine-config.
you should be able to set it to something like 4 GB or maybe 3GB so you can start your vms with the following command:
engine-config -s FreeSpaceCriticalLowInGB=3
After doing this you have to restart the engine service (service ovirt-engine restart) for the changes to take effect.
If you want to see what the current value is use engine-config -g FreeSpaceCriticalLowInGB.
To see a list of all configurable values you can use engine-config --list
Thanks, Gadi Ickowicz It did the trick, thanks!
Could this parameter impact in general only start of new VMs or in any way also already running VMs? Gianluca added gluster-users as they can responde to us questions.
Gianluca, as you are using glusterfs, and as I can see on your df output: /dev/mapper/fedora-DATA_GLUSTER 30G 23G 7.8G 75% /gluster/DATA_GLUSTER node01.mydomain:gvdata 30G 26G 4.6G 85% /rhev/data-center/mnt/glusterSD/node01.mydomain:gvdata be careful to gluster cluster.min-free-disk option, that on gluster 3.1 and 3.2 it's default option is 0% (good for you!) http://gluster.org/community/documentation//index.php/Gluster_3.2:_Setting_V... but I can't find the same documentation for gluster 3.4, that I suppose you're using this gluster version on ovirt; otherwise on red hat storage documentation cluster.min-free-disk default option is 10% (bad for you): https://access.redhat.com/site/documentation/en-US/Red_Hat_Storage/2.1/html/... so you fill your gvdata volume up to 90% and let we know if it's stop I/O (or only write) or we can wait for a clarification from gluster guy :-) best regards a -- Amedeo Salvati RHC{DS,E,VA} - LPIC-3 - UCP - NCLA 11 email: amedeo@oscert.net email: amedeo@linux.com http://plugcomputing.it/redhatcert.php http://plugcomputing.it/lpicert.php
