I believe you will do the = following:

 

“pvresive = /dev/sdb”

 

That will make the volume group now = be 600GB.

 

Then use “lvextend” to = enlarge the logical volumes, and whatever the proper tool is to extend the EXT3 filesystem.

 

Best to have the logical volumes = & volume group offline (“vgchange –a n”) before starting resizing.

 

Just my = $0.02.

Hello all.

I have an issue, that I am not sure how to address. =

How can I resize the physical volume if I change the geometry of the disk (non-destructive resize of RAID volume at the hardware level) =

I can see that the OS has picked up the new size of the disk and I would = like to resize the existing pv. I don't know how.

I started with a hardware raid 5 (400GB), linux automatically recognizes = disk as /dev/sdb

a simplistic representation of the setup is as follows =

pvcreate /dev/sdb
vgcreate VolGroup10 /dev/sdb
lvcreate -n LogVol10 VolGroup10
mkfs.ext3 /dev/mapper/VolGroup10-LogVol10

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.

filesystems OK
logical volumes OK
volume groups OK

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?
