Hi andyleigood,

As shown above, datavg the VG system is mounted in the LV was also in use, but should not see vgs in vg

to be more precise, the physical volume could not be found (judging from your output, VG “datavg” resides on a single PV), therefore “datavg” is unavailable.

I have to admit that your question is not really clear to me, because of the wording. I don’t understand why you mention VG “system” in the context of “datavg” - those are two separate VGs, according to your output. Neither do I understand what you’re after when asking “but should not see vgs in vg”. May I ask you to tell again what actually puzzles you?

Regards,
Jens

As you see:
df -hP
/dev/mapper/datavg-redoa_lv 10G 5.0G 5.1G 50% /oracleser/oradata/dsmdb/redo_a

“redoa_lv” is belong to “datavg”, and is using now.
But use “vgs” command cannot show “datavg”.
It’s mean “datavg” disappeared.

I want to know why?
How to solve it?

Volume group “datavg” not found [/QUOTE]

see my earlier reply - the physical volume could not be found, did you remove it? Probably a non-local disk (SAN device that went down? Or a dynamically attached USB disk? :smiley: ), You might be able to identify the physical device by looking at the output of “vgdisplay -v datavg”, look for the “— Physical volumes —” section.

Jens

Thank you Jens.
I’ll try it.
