[OpenIndiana-discuss] zpool completes resilver with no errors and then starts resilvering again

[russell]

Hi,

I have six disk raidz2, originally all disks were 3TB, swapped one 3TB 
for a 6TB, waited for the resilver to complete but then it immediately 
starts the next.

  state: ONLINE
status: One or more devices is currently being resilvered.  The pool will
         continue to function, possibly in a degraded state.

             c7t13d1p0  ONLINE       0     0     0

errors: No known data errors

I left the computer on all day and it took around 10 hours to complete a 
resilver then it started again.

No errors are being produced, any suggestions how to resolve this?
