Help with rebuilding shared filesystems.

[Hai Nguyen_1]

Folks,

Below is my current TESTING cluster configuration.

- cluster of two nodes A and B.
- One Package dbpkg.
- One volume group vg01 shared by A and B.
- Within vg01, two logical volumes lvol1 and lvol2 were created for filesystem1 and filesystem2 respectively. the two filesystems are controlled by dbpkg.

And now is what I want to do BUT do not know how yet.

1) stop the TESTING cluster permanently.
2) Remove lvol1, lvol2 within vg01 and then vg01 (I guess this needs to be done on both nodes.)
3) Remove the LUN assigned to vg01 from Virtual Array VA7100.

Please let me know if you think I miss anything which may make the computers not to function. Thanks.

Regards,
Hai

1. cmhaltcl -f
2. cmdeleteconf -f -c -p dbpkg
3. On both nodes: set AUTOSTART_CMCLD=0 in /etc/rc.config.d/cmcluster
4. On both nodes: run
vgexport vg01
5. Then you can remove the LUNs.
6. If you had previously modified /etc/lvmrc (e.g., AUTO_VG_ACTIVATE=0)
now you can change it back to the default (if you want)
