https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256205 --- Comment #8 from Robert Clausecker <fuz@fuz.su> --- (In reply to Alan Somers from comment #7) Hi Alan, The cache file /etc/zfs/zpool.cache is there and seems fine. Here is what = zdb -C outputs: # zdb -C tau: version: 5000 name: 'tau' state: 0 txg: 439 pool_guid: 2019163837599314243 errata: 0 hostname: 'eta' com.delphix:has_per_vdev_zaps vdev_children: 1 vdev_tree: type: 'root' id: 0 guid: 2019163837599314243 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 12664617697930720246 path: '/dev/da0p3' whole_disk: 1 metaslab_array: 131 metaslab_shift: 34 ashift: 12 asize: 1991530512384 is_log: 0 DTL: 302 create_txg: 4 com.delphix:vdev_zap_leaf: 129 com.delphix:vdev_zap_top: 130 features_for_read: com.delphix:hole_birth com.delphix:embedded_data Though interestingly, this does not match the pool label: # zdb -l da0s2a ------------------------------------ LABEL 0 ------------------------------------ version: 5000 name: 'tau' state: 0 txg: 112629 pool_guid: 12522957766422004777 errata: 0 hostname: 'tau.fuz.su' top_guid: 16278934493555373134 guid: 16278934493555373134 vdev_children: 1 vdev_tree: type: 'disk' id: 0 guid: 16278934493555373134 path: '/dev/da0s2a' whole_disk: 1 metaslab_array: 65 metaslab_shift: 31 ashift: 12 asize: 231409188864 is_log: 0 create_txg: 4 features_for_read: com.delphix:hole_birth com.delphix:embedded_data labels =3D 0 1 2 3=20 Could the cache file perhaps be stale? If yes, how do I fix this? --=20 You are receiving this mail because: You are on the CC list for the bug.=
