Swap on ZFS is unstable from revision r321453 (2017-07-25): /usr/src/sys/kern/subr_blist.c /usr/src/sys/sys/blist.h And fully broken from r321554 (2017-07-26): /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dbuf.c /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/metaslab.c /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa_misc.c /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/space_map.c /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/spa.h It happened between 11.1 and 11.2 release forks. Also, swap on ZFS fully broken in the current revision of stable/11 r342915 (kernel and world used). --=20 You are receiving this mail because: You are the assignee for the bug.=
