[linux-lvm] invalidate: busy buffer

[Petro]

Setup: 4 IBM drives attached to a 3ware raid card (64xx), in a raid 0
configuration, as /dev/sdb. 

Trying to set up LVM on it, run vgscan and get: 

vgscan -- reading all physical volumes (this may take a while...)
invalidate: busy buffer
invalidate: busy buffer

vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group


Is this a warning from LVM? If so, what does it mean (and if not, if
anyone does know what it means, I'd be really glad to find out). 

thanks.
