Hi all,
I merged today the last patches for supporting external leases.
In storage domain version 4 (the default in ovirt 4.1), there is now a new volume named "xleases".
When upgrading older storage domain (version 3), we create and format the new volume.
If you used a development version with storage domain version 4, your storage domain may not work with current master. You should recreated such storage domain.
As a workaround, you can create the special volume manually:
File storage:
sudo -u vdsm truncate -s 1G /rhev/data-center/mnt/server:_path/domain_uuid/dom_md/xleases
Block storage:
lvcreate --name xleases --size 1g domain_uuid
Note that the volume should be also be formatted to actually use external leases, but having it should be good enough to keep the system happy.
To create a fully functional xleases volume, you can use this patch: https://gerrit.ovirt.org/69069 Creating xleases volume on file storage: PATH=/rhev/data-center/mnt/server:_export/sd_id/dom_md/xleases truncate -s 1G $PATH vdsm-tool format-xleases sd_id $PATH Creating the xleases volume on block storage: lvcreate --name xleases --size 1g sd_id vdsm-tool format-xleases sd_id /dev/sd_id/xleases lvchange -an sd_id/xleases Nir
