Hi Eric, thanks for the pointer. I tried the patch and it works. regards, Shiva ________________________________ From: Eric Borisch [eborisch@gmail.com] Sent: Tuesday, October 01, 2019 5:03 PM To: Shiva Bhanujan Cc: Fabian Keil; freebsd-fs@freebsd.org Subject: Re: [ZFS] Potential silent data corruption when receiving incremental stream with block size change on receiving side That sounds like a potential hole birth issue. You might consider upgrading to at least 10.4 or 11.1 and re-trying the send; these added the vfs.zfs.send_holes_without_birth_time (default true/1) tunable to avoid "numerous hole_birth bugs". See this [1] commit. - Eric [1] https://svnweb.freebsd.org/base/releng/10.4/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dmu_traverse.c?revision=308086&view=markup On Tue, Oct 1, 2019 at 5:51 PM Shiva Bhanujan <Shiva.Bhanujan@quorum.com<mailto:Shiva.Bhanujan@quorum.com>> wrote: Hello, This seems to be an older email, but I seem to be hitting this in FreeBSD 10.3.

The previous incrementals don't have a mismatch. Can somebody please advise on what I should be looking for? I've checked the URLs mentioned here. The addition or removal of the -L option doesn't have any change.
