Solaris

Hi friends,

I'm newbie to SVM.
Just wanna try installed it on one of our server (to do mirroring for disk0 and disk1) but i think im lost until now.


the steps i've taken is as below:-

1.prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2

2.metadb -a -c 3 -f c1t0d0s7 c1t1d0s7

3.for 'd0'
-metainit -f d10 1 1 c1t0d0s0
-metainit -f d11 1 1 c1t1d0s0
-metainit d0 -m d10

4.metaroot d0

5.for 'd1'
-metainit -f d20 1 1 c1t0d0s1
-metainit -f d21 1 1 c1t1d0s1
-metainit d1 -m d20

6.for 'd3'
-metainit -f d30 1 1 c1t0d0s3
-metainit d31 1 1 c1t1d0s3
-metainit d3 -m d30

7.for 'd4'
-metainit -f d40 1 1 c1t0d0s4
-metainit d41 1 1 c1t1d0s4
-metainit d4 -m d40

8.vi /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/md/dsk/d1 - - swap - no -
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no -
/dev/md/dsk/d3 /dev/md/rdsk/d3 /var ufs 1 no -
/dev/md/dsk/d4 /dev/md/rdsk/d4 /export/home ufs 2 yes -
swap - /tmp tmpfs - yes -
root@mitv-t-cons01 >

9.reboot

10. metastat --> this is where the problem comes,
seems the metastat output keep on 'looping' even after the resync period complete.
problems is it keep on looping on d3 and not even show the d4.

Really appreciate your help guys!
Thanks!

1. please use code tags. command output is easier to read!

2. what is the output of "iostat -e"?

Hi DukeNuke2,

Please find the output.

Code:

if i run metastat -p,
still it will be in 'looping' mode.

Code:

metastat -p

d10 1 1 c1t0d0s0
d11 1 1 c1t1d0s0
d1 -m d20 d21 1

looks like an error in the creaton of device d30. from your last output d30 is the physical device d3. this won't work. you should try a fresh start.
copy back the old /etc/vfstab and /etc/system file and reboot your machine. after that "metaclear" all devices and start again.
