Hi, I am reinstalling a new Node with a new hosted-engine and I would like to import an iSCSI storage from a previous ovirt installation. However, I can see all LUN present on that iSCSI but the one I want... I checked from the iSCSI array and this disk still exists, it's just not detected from Ovirt (3.6)... I tried to make a new data domain and chosed that same iSCSI and it's also not detected.

I didn't remove the storage from the Engine interface on the previous installation, just just turned off all VMs accessing the iSCSI and unplugged the cable.

I didn't remove the storage from the Engine interface on the previous installation, just just turned off all VMs accessing the iSCSI and unplugged the cable. Is it possible there is still a lock file or something from the previous hypervisor ? _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

> Hi Alexis > Were you able to resolve your storage LUN issue? > Regards, > Kevin I am trying the suggested solution on this post by Nir Soffer : reconnect the storage to the older hypervisor and detach it correctly...But it doesn't work : From the DC : 1. I set the storage (which is master data domain) to maintenance mode 2. I try to detach it. I get this error message : "Error while executing action: Cannot remove the master Storage Domain from the Data Center without another active Storage Domain to take its place. -Either activate another Storage Domain in the Data Center, or remove the Data Center. 3. If I go in the storage domain menu, I get only the "destroy option", not "remove", which is maybe not what I want. I'd like to be able to keep the data on it. 4. If I try to remove the datacenter as suggested in the error message I get this error (as the hosted-engine storage is still up) : "Error while executing action: Cannot remove Data Center which contains active/locked Storage Domains. -Please deactivate all domains and wait for tasks to finish before removing the Data Center." 5. I can't set the hosted engine storage to maintenance What should I do ?
