I’m trying to add a new shared datastore and no matter what combination of settings i choose for the datastore i am unable to spin up a vm in that datastore. I always get the message “Image Datastore does not support transfer mode: shared”. ![Screenshot 2021-10-12 120428](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/a/a471ac3608b0088484344260cd1ce891b9f05c4a.png) ![Screenshot 2021-10-12 120600](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/8/8d84938e436bc65909fc27c1c9ab57dd0bdd152c.png) I’ve verified the permissions match on the folders and it is owned by the oneadmin user. i am able to ssh between hosts as oneadmin without password and create files in teh folder. permissions match between a working folder and the folder that doesnt work. I’ve also tried qcow2 mode with this result “Image Datastore does not support transfer mode: qcow2”, as well as creating a new cluster with the new datastore(s) and i still get the same results. I’ve tried restarting all teh opennebula services but still the issue persists. Any pointers would be appreciated or a copy of a working shared image datastore / system datastore. Also tried making a non-shared ssh datastore and am able to create VMs on the gluster / fuse mounted file but i am unable to migrate the VM live or otherwise. live fails saying the datastore isnt shared as expected, live fails saying “DEPLOY: Could not create domain from /raid/images/168/256/deployment.2” tried using the legacy built in glusterfs datastore as well but still get the same message that “Image Datastore does not support transfer mode: shared” no combination of things so far, has worked. anytime the shared option shows up in the image datastore it will throw that error. I’ve also tried setting base path but that is ignored as well as tinkering around with the shared TM\_MAD\_CONF in oned.conf but all to no avail. Also tried disabling all other datastores but the issue persists. disabling apparmor made no difference, nor did trying just normal files instead of the fuse mounted gluster shares. ---

This seems to be a misconfigured oned.conf, missing/wrong TM\_MAD\_CONF entries. Did you change something there? or are you using any TM\_MAD\_SYSTEM in the VM template? ---

Really appreciate the response, i’m totally out of ideas on this.

i have completely wiped and reinstalled on all my nodes, no changes have been made to any config files and this is still an issue. ---
