I have a dedicated server provided to me by 1and1. I started migrating websites to the server only to realise that I am running out of disk space. I had to clear my backups in order to continue migrating my sites. I thought this to be weird as the server comes with 4T of disk space.
On accessing the system via ssh. I see the following setup by 1and1:
#vgdisplay

Also #pvscan reveals this:
PV /dev/sda3 VG vg00 lvm2 [<54.00 GiB / <9.00 GiB free]
PV /dev/sdb1 VG hdd lvm2 [<3.58 TiB / <3.58 TiB free]
Can someone please let me know the best process for getting this unused free space in to the root volume group? I have searched and seen so many different answers. As I have already started migrating a number of websites. I cannot afford to break the server, otherwise I would have a fiddle, break, and learn as I usually do.
Just a thought failed to mention this is Hardware Raid 5
Update to question below:
#pvdisplay

I would like to reduce the physical volume in /dev/sdb1 by 2 or 3TB and increase /dev/sda3 by the same amount. Can this be done? If so what process would I need to follow?
If not I noticed mentioned in the replies "Migrating the websites to hdd" What process would I have to follow and what are the implications of doing this?

I increased the LV on /dev/vg00/var by 100% (This is where the websites are stored). but this will quickly be used up once I continue to migrate more sites over!
This may also help. This is from running the mount command I have removed additional lines:
/dev/sda1 on / type ext3 (rw,noatime,data=ordered)
/dev/mapper/vg00-usr on /usr type ext4 (rw,noatime,data=ordered)
/dev/mapper/hdd-data on /data type ext4 (rw,noatime,quota,usrquota,data=ordered)
/dev/mapper/vg00-home on /home type ext4 (rw,noatime,quota,usrquota,data=ordered)
/dev/mapper/vg00-var on /var type ext4 (rw,noatime,quota,usrquota,data=ordered)
Thank you for your responses much appreciated!
hdd
? Could you not simply migrate the websites to newly created LVs?
