joined #openzfs[12:48:58] <sindan> DHE I have usually understood that the send/recv is not communicating both ways, since it can be done over pipes; I didn't imagine how little state (or you might say verification) is needed for the recv part to start working. I learned this the hard way the other day, when I sent a replication stream from pool A, snap a to snap b, to a machine holding several pools (say A, B, C), and I sent that by mistake to recv -Fdv pool B. I al[12:48:58] <sindan> ways assumed that that was guarded against and that I would get some error attempting "cross-pool" things, but no. The recv metodically started destroying all of pool B on the receiving end because it was not pool A.[12:53:43] <sindan> But now I have another question: Does a stream include verification codes in it? iow if one bit changes in the stream would recv fail?[13:38:16] *** idwer <idwer!~idwer@unaffiliated/idwer> has quit IRC (Ping timeout: 255 seconds)[13:45:45] <DHE> sindan: the stream does include checksums to detect corruption in the stream[13:46:48] *** wiedi <wiedi!~wiedi@gianotti.chemnitz.freifunk.net> has joined #openzfs[13:47:15] <DHE> receive -F will explicitly delete the old dataset if trying to receive a full stream (non-incremental) over it, and if sending with -R it will delete any snapshots no longer present on the sending side when doing incrementals[13:47:21] <sindan> Oh cool, I was looking at http://open-zfs.org/wiki/Documentation/ZfsSend and yes it says so[13:49:53] <sindan> DHE I know, just didn't expect that my mistake would work, because both sides assume it's the same pool, and the pool name could be different on both sides.[13:51:24] <sindan> Still it would be cool to have to force the recv to proceed if pool names on src/dst didn't match. The send could include its pool name and the recv could check agains its own.[13:59:39] <DeHackEd> it does include the pool name, but the receiver largely doesn't care. for a replication send it does some name rewriting (see receive -d & -e)[13:59:56] <DeHackEd> the sender's side pool name is included in the receive token when doing resumable sends[14:02:53] <sindan> DeHackEd, yeah, just no verification of the type I was talking about. Not a problem if one never makes mistakes.
