[linux-lvm] LVM send/receive support?

[Gionatan Danti]

Hi all,
I wonder if using LVM snapshots (even better: lvmthin snapshots, which
are way faster) we can wire something like zfs or btrfs send/receive
support.

In short: take a snapshot, do a full sync, take another snapshot and
sync only the changed blocks.

I know that exists an utility called lvmsync[1], but it seem not
maintained anymore. Any suggestion on how to do something similar?

Thanks.

Hi Zdenek,
thanks for pointing me to thin_delta - very useful utility. Maybe I can code
around it...
As an additional question, is direct lvm2 support for send/receive planned, or
not?

Hi

It will certainly happen - just not sure in which year...
ATM higher prio tasks are on the table.
