I see 2 options :- backup via snapshot- snapshot on Gluster level and backup it Of course last option is to do file backup from OS.

Would that be some specific options to mount gluster vol in order to overcome: -> $ qemu-img convert -O qcow2 ./ubuntu.qcow2.bkp ubuntu.qcow2 qemu-img: Could not open './ubuntu-tor.qcow2.bkp': Could not open backing file: Failed to get shared "write" lock Is another process using the image [/VMs3/ubuntu.qcow2]? or perhaps 'qemu-img' can do the trick somehow? all thoughts shared are much appreciated. many thanks, L> _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/SIXBM2ZYDK2...
