Hi Mark,

probably check /etc/lvm.conf and see whether there could be accidentally
an exclusion that
matches the dasd name (like for example sdb1).
Otherwise the output of lsdasd would be helpful.

LVM trouble






I'm migrating a Linux guest from SLES 8 to SLES 9.  I created a new SLES 9
guest and copied the configuration information I needed for the
application.  In order to test LVM I've attached all the DASD read-only to
the new SLES 9.  But when I do a PVSCAN or LVSCAN  it only shows 10 of the
12 volumes.  I know that they are attached and a cat of /proc/dasd/devices
shows them as active.

But if I do a pvdisplay /dev/dasdb1  I get   Failed to read physical
volume
"/dev/dasdb1"

Is /dev/dasdb1 active? What does the LVM display in YaST show?

Any ideas?  Possibly the difference between LVM on SLES 8 & SLES 9?
