Hi.

I did:

>gmirror forget root
>gmirror list root
Geom name: root
State: COMPLETE
Components: 1
Balance: split
Slice: 4096
Flags: NONE
GenID: 7
SyncID: 1
ID: 1926374852
Providers:
1. Name: mirror/root
   Mediasize: 134217216 (128M)
   Sectorsize: 512
   Mode: r1w1e1
Consumers:
1. Name: da1s1a
   Mediasize: 134217728 (128M)
   Sectorsize: 512
   Mode: r1w1e1
   State: ACTIVE
   Priority: 0
   Flags: NONE
   GenID: 7
   SyncID: 1
   ID: 600760959
>gmirror insert root /dev/da0s1a

and got nothing:

>gmirror list root
Geom name: root
State: COMPLETE
Components: 1
Balance: split
Slice: 4096
Flags: NONE
GenID: 7
SyncID: 1
ID: 1926374852

   State: ACTIVE
   Priority: 0
   Flags: NONE
   GenID: 7
   SyncID: 1
   ID: 600760959


and some errors in /var/log/messages:

Feb 17 18:17:03 host2 kernel: GEOM_MIRROR: Device root: provider da0s1a detected.
Feb 17 18:17:03 host2 kernel: GEOM_MIRROR: Device root: rebuilding provider da0s1a.
Feb 17 18:17:05 host2 kernel: GEOM_MIRROR: Synchronization request failed (error=1). da0s1a[WRITE(offset=0, length=131072)]

Feb 17 18:17:05 host2 kernel: GEOM_MIRROR: Device root: rebuilding provider da0s1a stopped.

How to correct this error and insert da0s1a into the root?
