LVMREC

Robert Hunke — Mon, 02 Dec 2002 17:06:32 GMT

Using the lvcreate command, I was able to successfully create and extend my logical volumes, however I get an error
vgcfgbackup: Invalid LVMREC on Physical volume /dev/rdsk/c7t5d0. I have used all the suggestions in the tech docs. This seems to create a problem when I am exporting to another node. I have patched to be current with hp as of today. help!!!

Did you pvcreate the disk before attempting to add it into your volume group?

Hi:

You note that you have used "all suggestions in tech docs". Would you please be more specific? For instance, if this was a new disk (at least as far as the volume group is concerned), did you do a 'pvcreate' on it first? Does a 'dd' of the raw device produce errors?

Regards!

Yes, I did do a pvcreate on this disk. dd produces no errors on the raw device. There are a few entries in the tecnical documents when I search for LVMREC. The suggestion was to do a dd on the disk. vgreduce the volume group, and use pvcreate to re-create it. The thinking was that the header may be bad. I did follow these steps.

Well to check the header you may like to look at the following :
