Hi Steve, You mentioned you may have a fix for zfs_send.c in ZFS. Although Lustre tickles the bug, it's not likely that is the only way to tickle it.
Is there already a bug report for your issue at https://github.com/openzfs/zfs/issues? If not, can you create one, even if your patch isn't successful? That's the place to get your patch landed, and/or get help with the issue. thanks, -Olaf ________________________________________ From: lustre-discuss <lustre-discuss-boun...@lists.lustre.org> on behalf of Steve Thompson <s...@vgersoft.com> Sent: Tuesday, November 10, 2020 5:06 AM To: Hans Henrik Happe Cc: lustre-discuss@lists.lustre.org Subject: Re: [lustre-discuss] ZFS w/Lustre problem On Mon, 9 Nov 2020, Hans Henrik Happe wrote: > I sounds like this issue, but I'm not sure what your dnodesize is: > > https://github.com/openzfs/zfs/issues/8458 > > ZFS 0.8.1+ on the receiving side should fix it.

I had in fact known about the dnodesize issue, and tested a workaround. Unfortunately, it turned out not to be this. Instead, I have tested a patch to zfs_send.c, which does appear to have solved the issue. The zfs send/recv is still running, however; if it completes successfully, I will post again with details of the patch.
