Subject: Chiara disk clean up and internally mounted 

[Koji Gautam]

Took the opprtunity of the power glitch to take care of the disk situation of chiara.

- Unmounted /cvs/cds from nodus. This did not affect the services on nodus as they don't use /cvs/cds

- Go to chiara, shut it down, and physically checked the labels of the drives.

root = 0.5TB
/cvs/cds = 4TB HGST
backup of /cvs/cds= 6TB HGST

- These three disks are internally mounted and connected with SATA. Previously, 6TB was on USB.

- There were two other drives (2TB and 3TB) but they seemed logically or physically broken. These two disks were removed from chiara. (they came back online after reformatting on mac. So they seem still physically alive).

- Rebooted the machine and just came back without any error. This time the control room machines were not shutdown, but they just recovered the NFS once chiara got back.
