https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252331 Bug ID: 252331 Summary: zfs over ggate terminates ggated with 0 length read Product: Base System Version: 12.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: ota@j.email.ne.jp When ZFS is used over ggate devises, ggated somehow receives 0 length read and results in terminating ggatec and ggated connection. How to reproduce: % mdconfig -a -t swap -s 1GB md0 % echo 127.0.0.1 RW /dev/md0 > /tmp/ggated.conf % ggated /tmp/ggated.conf % ggatec create -orw 127.0.0.1 /dev/md0 ggate0 % zpool create -m /mnt/test test /dev/ggate0 % cp -pr /usr/src/ /mnt/test/ ggate connection is dropped randomly. After running truss, I discovered that ggated read 0 length input from a socket and closes the connection although ggatec does not write 0 length over the connection. As a result, ggatec terminates its connection as well and zfs/cp hangs. -- You are receiving this mail because: You are the assignee for the bug.home | help
