I don't know how.<o:p></o:p> I started with a hardware raid 5 (400GB), linux automatically recognizes disk as /dev/sdb <o:p></o:p> a simplistic representation of the setup is as follows <o:p></o:p> pvcreate /dev/sdb vgcreate VolGroup10 /dev/sdb lvcreate -n LogVol10 VolGroup10 mkfs.ext3 /dev/mapper/VolGroup10-LogVol10 <o:p></o:p> I have added a disk and expand the array to 600GB I can still see every thing but I don't know how to extend the PV. <o:p></o:p> filesystems OK logical volumes OK volume groups OK <o:p></o:p> linux sees /dev/sdb as 600GB pvs shows pv /dev/sdb is 400GB. I wish to, non-destructively, reinitialize /dev/sdb so that pvs shows 600GB. how? <o:p></o:p> <o:p> </o:p> William T.
