I did the following:

# zpool status
  pool: pool
 state: ONLINE
 scan: none requested
config:

	NAME            STATE     READ WRITE CKSUM
	pool            ONLINE       0     0     0
	  raidz1-0      ONLINE       0     0     0
	    ada2        ONLINE       0     0     0
	    ada3        ONLINE       0     0     0
	    ada4        ONLINE       0     0     0
	    ada5        ONLINE       0     0     0
	    ada6        ONLINE       0     0     0
	    ada7        ONLINE       0     0     0
	cache
	  label/zcache  ONLINE       0     0     0

errors: No known data errors

so far so good

[root@server4 /pool/home/jeanyves_avenard]# zpool add pool log
/dev/label/zil [root@server4 /pool/home/jeanyves_avenard]# zpool
status
  pool: pool
 state: ONLINE
 scan: none requested
config:

	NAME            STATE     READ WRITE CKSUM
	pool            ONLINE       0     0     0
	  raidz1-0      ONLINE       0     0     0
	    ada2        ONLINE       0     0     0
	    ada3        ONLINE       0     0     0
	    ada4        ONLINE       0     0     0
	    ada5        ONLINE       0     0     0
	    ada6        ONLINE       0     0     0
	    ada7        ONLINE       0     0     0
	logs
	  label/zil     ONLINE       0     0     0
	cache
	  label/zcache  ONLINE       0     0     0

errors: No known data errors

so far so good:

# zpool remove pool logs label/zil
cannot remove logs: no such device in pool

^C

Great... now nothing respond..

Rebooting the box, I can boot in single user mode.
but doing zpool status give me:

ZFS filesystem version 5
ZFS storage pool version 28

and it hangs there forever...

What should I do :( ?

Rebooting in single-user mode.

zpool status pool
or spool scrub pool

hangs just the same ... and there's no disk activity either ...

Will download a liveCD of OpenIndiana, hopefully it will show me what's
wrong :(

Is that a typo, or the actual command you used?  You have an extra "s"
in there.  Should be "log" and not "logs".  However, I
don't think
that command is correct either.

I believe you want to use the "detach" command, not
"remove".

# zpool detach pool label/zil
