Increase space on part/lvm or mount

So, long story short, got a server(EC2) with 2 EBS pointed to it. (100G & 200G). Upon investigation, I come across that the /var/www mount has only 50GB assigned. My requirement is to increase this 50GB's to 100GB if possible. The structure of the disk is as the below image. Above is the output I get when I run the lsblk command. Below is what it seems to be running on. CentOS release 6.10 (Final) 17.8.11 cos6.build1708180301.19 This also has Plesk installed. I am open to installing a plugin. -----PVS,VGS,LVS PVS Output PV VG Fmt Attr PSize PFree /dev/xvdj1 data lvm2 a--u 50.00g 0 VGS Output VG #PV #LV #SN Attr VSize VFree data 1 1 0 wz--n- 50.00g 0 LVS Output LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert www data -wi-ao---- 50.00g
