Are hot spares implmented yet?
I got Solaris 2006 6/06 installed and setup a ZFS pool and ZFS filesystem.
# zpool status
pool: data
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
data ONLINE 0 0 0
mirror ONLINE 0 0 0
c4t60001FE1000DAD9000092110348000DAd0s2 ONLINE 0 0 0
c4t60001FE1000DAD9000092110348000D7d0s2 ONLINE 0 0 0
mirror ONLINE 0 0 0
c4t60001FE1000DAD9000092110348000E0d0s2 ONLINE 0 0 0
c4t60001FE1000DAD9000092110348000C3d0s2 ONLINE 0 0 0
...etc...
errors: No known data errors
I assumed I was going to be able to add spares later, but when I tried to add a
spare, it said:
# zpool add data spare c4t60001FE1000DAD9000092110348000F5d0s2
cannot open ''spare'': no such device in /dev/dsk
must be a full path or shorthand device name
I tried to add my spare(s) as art of the create subcommand and got the same
message.
For some reason, it doesn''t seem to be implemented. My zpool man page
says this:
The pool names "mirror", "raidz", and
"spare" are reserved, as are names
beginning with the pattern "c[0-9]".
I look at the binary to see that it wouldn''t understand
"spare" as being special at all.
# strings /usr/sbin/zpool | egrep ''spare|mirror|raidz''
mirror
raidz
mirror
raidz
So I suspect I don''t have support for hot spares in Solaris 2006 6/06
(aka U2).
Is there a Nevada version which supports zpool spares? My "uname
-srv" says I have "SunOS 5.11 snv_40". or is there an update I
can get?
Thanks, ez
