raid10 in ZFS I'm ok with this

Hi all,
we are used to do raid 10 with solaris box but are looking to replace that with nas4free or freenas.
So I have a test nas4free server with 5 drives and want to test driive raid10
I go to ssh and I create the pool like this
Code: Select all
zpool create -m /mnt/storage storage mirror da1 da2 mirror da3 da4 spare da5
and if I check the status like this
==> zpool status
All is perfect
Code: Select all
pool: storage
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
storage ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0
mirror-1 ONLINE 0 0 0
da3 ONLINE 0 0 0
da4 ONLINE 0 0 0
spares
da5 AVAIL
errors: No known data errors
If I go back in the wui I see my pool under the Detected TAB of ZFS but I dont see anything in the other tab, normal ?
I export my zool and re imported it with the wui and I dont see more details
Is this normal that I dont see the actual detail in the wui other than in the detected tab ?
I can share nfs over this so it seems to be fine but I want to ask before I start using it in the wrong way
In freenas I dont see any details of the pool but in nas4free I can see it in the detected part so that why I'm trying nas4free !
Thanks for any input on this
Guillaume

YES until use sync button to sync detected with webGUI
sync button is in Disks|ZFS|Configuration|Synchronize page

Wow thanks just incredible, this has convince me to switch, for the record I saw that ZFS hotspare is not working in freenas
http://doc.freenas.org/index.php/Volumes#ZFS_Extra if you look under Spare you will see,
Now is this supported under nas4free ?
From my test env I just remove # of the drive and the Spare did not kick in auto magically to we need to activate something ?
Code: Select all
nas4free:~# zpool status
pool: storage
state: DEGRADED
status: One or more devices has been removed by the administrator.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Online the device using 'zpool online' or replace the device with
'zpool replace'.
scan: none requested
config:
NAME STATE READ WRITE CKSUM
storage DEGRADED 0 0 0
mirror-0 ONLINE 0 0 0
da1 ONLINE 0 0 0

Hi,
Great but not sure it is working... Or maye I'm not waiting enough
I just tested it and the spare does not go in the mirror, how long do we have to wait ? I have disconnect 1 drive for more than 5 min ... Maybe I'm missing something this is a default install of nas4free...

First
zpool replace storage 17127724748045906489 da2
resilver etc....
after physically removing the disc hot da2
under these conditions "autoreplace" works
BUT
This motherboard don't support hotswap.....So not sure it does not crash the system.
