https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263501 Bug ID: 263501 Summary: zdb failure: zdb failed to hold dataset 'tank/ROOT/default': No such file or directory Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: mason@blisses.org In BZ#263407 it seems that the bootloader struggles to deal with files with holes immediately after them. In that bug's comments, kevans noted zdb output that displays the properties of affected and unaffected files, doing something like this: # zdb -vvvvvvO tank/ROOT/default boot/kernel/geom_eli.ko Unfortunately, while this works for OpenZFS built for Debian, on FreeBSD 13.0, and on FreeBSD 12, I'm finding that it consistently fails on 13.1 installs, giving me this message: zdb failed to hold dataset 'tank/ROOT/default': No such file or directory My immediate concern is that 13.1-RC4 doesn't display the bad behaviour from the original bug, so testing a fix will involve contructing a file to match the problematic pattern, using posix-fallocate or or ftruncate or somesuch. However, without being able to use zdb, it'll be significantly more difficult to verify that the file(s) in question match the pattern or not. -- You are receiving this mail because: You are the assignee for the bug.
