raid10 in ZFS I'm ok with this

[bougui]

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

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

 state: DEGRADED

	Sufficient replicas exist for the pool to continue functioning in a
	degraded state.

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.
