Description Lukáš Czerner 2013-10-02 11:06:29 EDT
Implement command 'migrate' for migrating whole volumes or just devices to a different one regardless on the backend used. Ssm should be able to handle this operation in a unified fashion for all supported backends.

For lvm based volumes, pvmove can be used.
For btrfs based volumes, btrfs replace feature can be used.

In case of regular devices we can use either dd, or something smarter which will probably end up to be file system dependent.

Comment 3 Alasdair Kergon 2014-07-02 20:35:55 EDT
Note that we're extending the pvmove syntax in 7.1 to support all-or-nothing migrations.
Comment 8 Jan Tulak 2018-06-19 11:00:58 EDT
Implemented in the upstream v1.0 release.
