Can't see some space

[kapa]

After I add one 750GB disk in 4x750GB-disk raid-5 array and rebuild it, I can see 3000GB of space in raid console:

But in Open-E window I see only 2095.48GB


How can I fix this?

Did you use pvresize from the console to add the new drive (space) ?
also do a rescan then in the unit manager did you add the new space to the volume group?
There may be a reboot involved.

also do a rescan

nothing changes

There may be a reboot involved.

reboot made some help - now I can see 2793.97GB :
