Re: [linux-lvm] Error on lvcreate or lvremove!



Heinz,

Thanks for your help, it worked.
However, I do not understand why I had this problem and how your suggestion
make
it work. The logical volume number is managed by LVM functions.

Another question is

I have the same problem as mentioned in "Poul Petesen's LVM1.04 pvmove is
broken" email
today as
        4) The RedHat 7.2 call to vgscan in rc.sysinit happens before
            mounting other file-systems, for example "/usr". This causes the
1.1-rc2
            vgscan to fail since libreadline is in /usr/lib.
I did not have this problem on LVM1.0.x. Now, I need to enable LVM and mount
all of these volumes after system boot manually.

Any suggestion or fixes?

Thanks,

Bo
