spa_upgrade_errlog() does not update the MOS directory when the head_errlog feature is enabled. In this case if spa_errlog_sync() is not called, the MOS dir references the old errlog_last and errlog_sync objects. Thus when doing a scrub a panic will occur: Call Trace: dump_stack+0x6d/0x8b panic+0x101/0x2e3 spl_panic+0xcf/0x102 [spl] delete_errlog+0x124/0x130 [zfs] spa_errlog_sync+0x256/0x260 [zfs] spa_sync_iterate_to_convergence+0xe5/0x250 [zfs] spa_sync+0x2f7/0x670 [zfs] txg_sync_thread+0x22d/0x2d0 [zfs] thread_generic_wrapper+0x83/0xa0 [spl] kthread+0x104/0x140 ret_from_fork+0x1f/0x40 Fix this by updating the related MOS directory objects in spa_upgrade_errlog().
