The "dataset_name" node= is supposed to contain the name of the ZFS dataset. But on both FreeBSD 13.1 = and 13.2 I am seeing some dataset_name nodes that are corrupted. They contain = the name of one dataset suffixed by part of the name of another. For example, sysctl shows a node named: kstat.zfs.MYPOOL.dataset.objset-0x1982c.dataset_name: MYPOOL/MYDS/transfer/273/0 But no such dataset is present. Instead, that name seems to be synthesized= by a combination of the following dataset names: NAME OBJSETID MYPOOL/MYDS/273/0 104492 MYPOOL/MYDS/transfer 17007 One possible cause, which I haven't verified, would be ZFS renames. It may= be that "zfs rename MYPOOL/MYDS/transfer/273/0 MYPOOL/MYDS/273/0" doesn't upda= te the value of that sysctl node. This bug is most apparent when using sysutils/ztop. --=20 You are receiving this mail because: You are the assignee for the bug.=
