https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230910 --- Comment #5 from Volodymyr Kostyrko <arcade@b1t.name> --- Looks like I partially know whats going on here. First when I tried to partition drives they were just freebsd-boot, freebsd-swap and freebsd-zfs.= But when that failed to work I=C2=A0sliced out 1G=C2=A0out of last one into oth= er partition: # gpart show da0 =3D> 40 781422688 da0 GPT (373G) 40 256 1 freebsd-boot (128K) 296 67108864 2 freebsd-swap (32G) 67109160 2097152 3 freebsd-ufs (1.0G) 69206312 712216408 4 freebsd-zfs (340G) 781422720 8 - free - (4.0K) arcade@cis\/home/arcade# zpool status mycon pool: mycon state: ONLINE scan: scrub repaired 0 in 0h33m with 0 errors on Mon Aug 13 04:45:19 2018 config: NAME STATE READ WRITE CKSUM mycon ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 da0p4 ONLINE 0 0 0 da1p4 ONLINE 0 0 0 da2p4 ONLINE 0 0 0 errors: No known data errors Here what it shows during "good" boot: Reconstructed root pool config: version: 5000 name: mycon state: 0 txg: 19961181 pool_guid: 14318237666280658641 hostid: 2404943215 hostname: cis.mix101.info vdev_children: 1 features_for_read: com.delphix:hole_birth: false com.delphix:embedded_data: false vdev_tree: type: root id: 0 guid: 14318237666280658641 children: children[0]: type: raidz id: 0 guid: 17901688662798610243 nparity: 1 metaslab_array: 39 metaslab_shift: 33 ashift: 12 asize: 1093949718528 is_log: 0 create_txg: 4 children: children[0]: type: disk id: 0 guid: 3986367950682223964 path: /dev/da0p4 whole_disk: 1 DTL: 177 create_txg: 4 children[1]: type: disk id: 1 guid: 9245294472961478945 path: /dev/da1p4 whole_disk: 1 DTL: 176 create_txg: 4 children[2]: type: disk id: 2 guid: 5056913690226738568 path: /dev/da2p4 whole_disk: 1 DTL: 175 create_txg: 4 This means that ZFS finds correct pool marks on partition already grabbed by geom_mirror and fails when trying to construct pool because kernel would not allow rw access there. I'll go zero out my ufs partitions... --=20 You are receiving this mail because: You are the assignee for the bug.=
