https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=297233 --- Comment #3 from Rick Macklem <rmacklem@FreeBSD.org> --- Hmm. This Illumos server appears to be broken. When there is no working callback path, the server is not supposed to issue delegations, but it appears to have done so. Does your kernel have commit 71ac1ec5c9? (It was committed to main on Apr. 30, 2026, so if your kernel is built from sources after that date, it does.) --> This patch was meant to ensure that NFSv4.0 servers did not issue delegations, by specifying a callback path address of 0.0.0.0. If you have this patch, then the NFSv4.0 server definitely will not be able to do callbacks. If the Illumos 4.0 (not 4.1 or 4.2) server is issuing delegations in this case, I can't think of a way to fix things. (Maybe Illumos has some "turn off delegations" switch for their server?) If you cannot figure out how to disable issuance of delegations for the Illumos server, you could try reverting 71ac1ec5c9 (or using a different server that supports NFSv4.1). -- You are receiving this mail because: You are the assignee for the bug.home | help
