https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256582 Bug ID: 256582 Summary: ZFS unable to attach/replace disk to the mirror/raidz Product: Base System Version: 13.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: serzh@expir.org I had a mirror of root partition on four disk. It was created a long time a= go, last changes were made in 12.2-RELEASE Yesterday I have faced a problem attaching new mirror to the pool, every ti= me I got an error like this: cannot attach ada0s1 to diskid/DISK-K648T9125YHPs4: can only attach to mirr= ors and top-level disks replace also didn't worked for me: zpool replace tz diskid/DISK-K648T9125YHPs4 ada0s1 cannot replace diskid/DISK-K648T9125YHPs4 with ada0s1: already in replacing/spare config; wait for completion or use 'zpool detach' I was able to detach all the copies of the mirror, but even after left only= one drive I sill was not able to add any mirrors to that pool I even tried to do it on another machine with the same error. Ok. maybe some problems with the pool, I wanted for a long time change mirr= or with raidz. I have created new raidz pool on one disk, hoping to replace slices after successful boot on the target machine. zfs send/receive have finished an the system successfully booted from the new disk: # zpool status -v t1 pool: t1 state: ONLINE scan: scrub repaired 0B in 00:10:16 with 0 errors on Sun Jun 13 19:43:27 = 2021 config: NAME STATE READ WRITE CKSUM t1 ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 ada0s1 ONLINE 0 0 0 ada0s2 ONLINE 0 0 0 ada0s3 ONLINE 0 0 0 ada0s4 ONLINE 0 0 0 But I still unable to replace any disk in the pool: # zpool replace t1 ada0s4 ada2s4 cannot replace ada0s4 with ada2s4: already in replacing/spare config; wait = for completion or use 'zpool detach' # zdb -C t1 MOS Configuration: version: 5000 name: 't1' state: 0 txg: 1975 pool_guid: 6410165186213320141 errata: 0 hostname: 'proxy.expir.org' com.delphix:has_per_vdev_zaps vdev_children: 1 vdev_tree: type: 'root' id: 0 guid: 6410165186213320141 create_txg: 4 children[0]: type: 'raidz' id: 0 guid: 7617222505941286006 nparity: 1 metaslab_array: 256 metaslab_shift: 30 ashift: 9 asize: 171779817472 is_log: 0 create_txg: 4 com.delphix:vdev_zap_top: 129 children[0]: type: 'disk' id: 0 guid: 8241112573820439777 path: '/dev/ada0s1' whole_disk: 1 DTL: 1111 create_txg: 4 com.delphix:vdev_zap_leaf: 130 children[1]: type: 'disk' id: 1 guid: 9546081964875052177 path: '/dev/ada0s2' whole_disk: 1 DTL: 1110 create_txg: 4 com.delphix:vdev_zap_leaf: 131 children[2]: type: 'disk' id: 2 guid: 14962733358913721879 path: '/dev/ada0s3' whole_disk: 1 DTL: 1109 create_txg: 4 com.delphix:vdev_zap_leaf: 132 children[3]: type: 'disk' id: 3 guid: 6900695808444206279 path: '/dev/ada0s4' whole_disk: 1 DTL: 1108 create_txg: 4 com.delphix:vdev_zap_leaf: 133 features_for_read: com.delphix:hole_birth com.delphix:embedded_data I have tried to add new disks as spares, but still was not able to replace = any of the current members of raidz What is going on? I think it is a bug, the error is certainly not related to the current configuration. --=20 You are receiving this mail because: You are the assignee for the bug.=
