Extend a VG online, with online JFS

[Ganesan R]

Hi Again,

I suspect that you have imported in preview mode on secondary. is it?

You have to import it in normal mode not the preview mode.

#vgimport -v -s -m

Hi,
you will need to add it manually.

ioscan and insf been done, tried it in preview and 'proper' mode (without the -p) and still nothing extra in /etc/lvmtab. Output says "Beginning import... blah blah" then "Volume group already in /etc/lvmtab"

Hi,

>>>Output says "Beginning import... blah blah" then "Volume group already in /etc/lvmtab"<<<

As per this message, vg is already there in lvmtab file.

Can you post the volumegroup names you are trying to import and #strings /etc/lvmtab output from secondary node ?

I'm aware of this, I was just providing the text output, but that is all I get, /etc/lvmtab does not get updated.

ok check if the vg that you like to import is in the /etc/lvmtab.

It is already there, with the unextended set of devices..

I can get a strings of /etc/lvmtab off but it will take a while due to the nature of the system.

Hi,

If you are not providing the output we asked, it is little difficult to help you out. We are interacting through forum. So it is not possible to understand the issue correctly unless you provide all the necessary details.

ok. back to your reply.

Does current lvmtab file has entry about the vg or not? Or provide the exact steps you followed starting from exporting on primary node to importing on alt node.

Hi I appreciate the help and I haven't said I won't get the input, I'm just explaining that its difficult due to the security of the system.

Yes, the vg is in the /etc/lvmtab on both nodes. On the Primary node it has the newly added devices too, on the Standby node following the import, it does not have the extended devices.

I will try and get the info off and update the forum later.

Process followed..

Extend VGs on Primary, extend LVs, fsadm on mount points. Create map file

# vgexport -p -s -m /tmp/redo1.map /dev/vg_ora_coredb_redo1

Copy map file to Secondary node.
ioscan and insf -e on secondary node.

# vgimport -s -m -v /tmp/redo1.map /dev/vg_ora_coredb_redo1
