Maybe not issue, but playing one of these things is not like the other I notice of all the bricks only one seems to be different at a quick glance
Brick : Brick 1.1.1.235:/bricks/20 TCP Port : 49170 RDMA Port : 0 Online : Y Pid : 26736 File System : ext4 Device : /dev/mapper/vol0-vol_root Mount Options : rw,relatime,data="" Inode Size : 256 Disk Space Free : 86.1GB Total Disk Space : 96.0GB Inode Count : 6406144 Free Inodes : 6381374
Every other brick seems to be 7TB and xfs but this one.
