pvdisplay question

Alex Lavrov. — Wed, 13 Jul 2005 02:55:33 GMT

Hello,

I have a question about pvdisplay. I had a VG with one PV connected by two channels. Primary and alternate.

I disconnected one channel and did vgreduce to one of the paths. Then, I connected it back and did pvdisplay on that disk. I got error which said that this PV does not belong to LVM. Weird, it's the same disk in VG. I did vgextend anyway, it worked and after this pvdisplay worked on it.

The question is why I got this message? Is it because the disk was not in /etc/lvmtab?

Thanx.

hi,

yes since the entry is not in /etc/lvmtab , you are getting this message ....

once vgreduce command is executed the entry from /etc/lvmtab is removed....so the vg has only one pv in it...

Hi,

Yes, you got the message because the alternate link wasn't on the /etc/lvmtab.

Strange ... for some reason I thought that pvdisplay checks the disk itself ...

Thanx.

Since pvdisplay is part of LVM it will probably always use /etc/lvmtab to check. You
