After i resized volumes (resize2fs /dev/vg/thin_pool), in Virtualizor / Storage Overview i see old size values while "df" command shows new values and "lvs" command too. I already tried to restart Virtualizor service on my CentOS 6 but not fixed it.

Update: After some time values was updated, but the Virtualizor staff advised this: "to reflect the new size please edit the storage and save it again. It should update the new size".

If do not work, try to navigate to the Servers section, manage the server, or go to server editing and back to Storage overview.
