What is the best way to move an rbd image to a different pool. I want to move some 'old' images (some have snapshots) to backup pool. For some there is also a difference in device class.
This is what I found on the mailing list, but it is from 2018. So
maybe
this is outdated?
rbd export --export-format 2 vms/vm-102-disk-2 - | rbd import -- export- format 2 - vdisks/vm-102-disk-2
why this and not eg 'rbd cp'
I guess I will have to use the 'rbd deep cp'. It would be nice to have 'rbd mv' so you are sure dest and source are the same, otherwise the command would fail. sha256sum /dev/rbd/rbd/test-copy 49084eb0c282f378b5eac865d71582d46d84b818ce003b7f3abfa6afc397a919 /dev/rbd/rbd/test-copy rbd snap create test-copy@snap1 head -c 3G </dev/urandom > /dev/rbd/rbd/test-copy sha256sum /dev/rbd/rbd/test-copy e16059ccfe2e5bea6e0c1c47b1755457acad1be6ad7162e370f28bb3084dc76d /dev/rbd/rbd/test-copy e16059ccfe2e5bea6e0c1c47b1755457acad1be6ad7162e370f28bb3084dc76d /dev/rbd/rbd.backup/test-copy rbd deep cp rbd/test-copy rbd.backup/test-copy rbd snap protect rbd/test-copy@snap1 rbd clone rbd/test-copy@snap1 rbd/test-copy-clone rbd snap protect rbd.backup/test-copy@snap1 rbd clone rbd.backup/test-copy@snap1 rbd.backup/test-copy-clone rbd map rbd/test-copy-clone sha256sum /dev/rbd/rbd/test-copy-clone sha256sum /dev/rbd/rbd/test-copy-clone 49084eb0c282f378b5eac865d71582d46d84b818ce003b7f3abfa6afc397a919 /dev/rbd/rbd/test-copy-clone sha256sum /dev/rbd/rbd.backup/test-copy-clone 49084eb0c282f378b5eac865d71582d46d84b818ce003b7f3abfa6afc397a919 /dev/rbd/rbd.backup/test-copy-clone
