>Description:

Hello

We have these 2 disks which original size is: 2794 GB

(root!seeed)(~)# dmesg |grep sd[0-1]
sd0 at scsibus0 target 14 lun 0: <HGST, HUS724030ALS640, A1C4> disk fixed
sd0: 2794 GB, 308240 cyl, 8 head, 2376 sec, 512 bytes/sect x 5860533168 sectors
sd0: tagged queueing
sd1 at scsibus0 target 15 lun 0: <HGST, HUS724030ALS640, A1C4> disk fixed
sd1: 2794 GB, 308240 cyl, 8 head, 2376 sec, 512 bytes/sect x 5860533168 sectors
sd1: tagged queueing
boot device: sd0
root on sd0a dumps on sd0b

However, fdisks and disklabel shows it different and I can only use 700 GB (2 TB is gone)
