Sometimes I see the old drive but after a resilver the pool is always "online" and healthy.
I would double check that the new drive is connected with power & data cables, then re-run the resilver.
Does SMART show anything funky for any of the drives ??

The second resilver passed and no change. The old ada8 is still in the list and the pool degraded.
I scrub is running. Maybe it would helps
The problem is, I cann't do anything with ada8. Answer: "cannot xxxxxxxx ada8: no valid replicas"
ANy things I can do?

try to use new button "clear config & import Disk" to delete non existing ada8, and next go to Disks|ZFS|Configuration| and post your current and detected to see it.

"clear & import disk": I did it repeated.
see the ZSF Config and Disk Management in the attachment

sorry , not enought knowledge to be sure, but suspect that you need to inform ZFS that replace disk:
http://wiki.nas4free.org/doku.php?id=faq:0149
http://docs.oracle.com/cd/E19253-01/819 ... index.html
but as I say not totally sure, wait other ZFS guru for instructions prior to do something potentially dangerous.
something like:
Code: Select all
zpool replace Pool 4149419797668455597 replacing-0
must work ( not totally sure because
Code: Select all
zpool replace Pool 4149419797668455597 ada8
is the other option)

There is a Backup of all important data
First answer:
Code: Select all
geckonas: /dev # zpool replace Pool 4149419797668455597 replacing-0
cannot open 'replacing-0': no such GEOM provider
must be a full path or shorthand device name
Second:
Code: Select all
geckonas: /dev # zpool replace Pool 4149419797668455597 ada8
invalid vdev specification
use '-f' to override the following errors:
/dev/ada8 is part of active pool 'Pool'
Maybe the problem could be, that replacing-0 is part of the vdev, and ada8 is only part of the pool. Something went wrong by replacing ada8

Next try:
Code: Select all
geckonas: /dev # zpool detach Pool replacing-0
cannot detach replacing-0: no such device in pool
geckonas: /dev # zpool detach Pool 4149419797668455597
cannot detach 4149419797668455597: no valid replicas
geckonas: /dev # zpool detach Pool replacing-0
cannot detach replacing-0: no such device in pool
geckonas: /dev # zpool detach Pool replacing
cannot detach replacing: no such device in pool
geckonas: /dev # zpool detach Pool ada8
cannot detach ada8: no valid replicas

Next:
geckonas: /dev # zpool online Pool 4149419797668455597
warning: device '4149419797668455597' onlined, but remains in faulted state
use 'zpool replace' to replace devices that are no longer present
geckonas: /dev #
Result:
Code: Select all

ada9 ONLINE 0 0 0
ada10 ONLINE 0 0 0 (resilvering)
I think, I will document my way, if we can solve the issue someone else can use it.
I know, I do it with high risk, that a can lose my pool.

try zpool -f replace Pool 4149419797668455597 ada8
PD: not sure if -f is in good place, can be zpool replace -f Pool 4149419797668455597 ada8

I will try -f as last option before a set up a new pool and a new poolwill take about 2 week
If the resilvering finished I try to remove 4149....

Have you looked at the documentation for replacing a disk?
http://docs.oracle.com/cd/E19253-01/819 ... index.html
You replaced ada8 with ada10 ? Has ada8 been removed from the box ? If yes, this command should work:
zpool replace Pool ada8
Have you rebooted since the new drive was added ?

Yes

zpool replace Pool ada8
No, I replaced ada8. During resilver ada8 went removed. Reboot without changing anything ada8 was in place and the result was the status above
After every reboot it restarts resilver ada8 and ada10
Have you rebooted since the new drive was added ?
More when one times .-)

Nothing changed after resilver.
I start my backup plan:
Out the moment I copy all data to a second NAS (about 10TB) and than I will rebuild the NAS4Free.

I couldn't resolve ist, so I did a new set up of the NAS
Now it is fine.
