Extend disk space to Exsi virtual hosts via DELL storage server.

Environment: EXSI HP Storage. The server connects to the storage server through the fibre switch.

A file server has been down recently. The prompt disk is insufficient, at first I thought that the system disk is insufficient. Enter the system looked down, sent down the system disk 80% is not used. So it is suspected that the exsi disk is insufficient. Look at the disk that the virtual machine is mounted on.

At that time, my free space was 0.2M.

For what I understood at the time.

Capacity: The amount of disk space that has been allocated to this virtual machine.

free space: How much space can be allocated for this disk.

I think: if I have a disk total of 600G, I assign it all to the virtual machine does not matter. That is, the disk free space: 0. Later, when the virtual server went down, I felt that things might not be as simple as I thought, so I added a lot of virtualization groups. Asked some of the people.

What they say is: If you have a 600G disk. You want to give all of the virtual server, where the snapshot of the virtual server, where it produces redundant files, where to put. When the disk has no space to hold these doer (snapshots and redundant files), your server will be down. Although it can be switched on again, it will be down in a few minutes.

listen to them said: I seem to understand, a person can not just honest, to leave some space out, 600G at least leave a 100G bar. Choose the size according to your needs.

But already, the snapshot was deleted because of the outage. What to do? Think of a virtual server that is connected to Dell's storage. That is only to expand the chant.

1. Check the server number for this exsi physical machine

2. Found in the storage server. Exsi Server tag code for physical host

3. View the volumes allocated by this server

4. Select the volume allocated by the EXSI physical host where the virtual server resides. To expand.

5. See if space changes after disk expansion

6. Return to the Exsi physical host for disk expansion.

7. Click Add. Can.

Ok! The expansion of the virtual host disk is complete. View the results. The disk space is getting bigger. The whole process of the original disk is a data storage. Directly after the online expansion. No data loss found. If the data is very important. Please back up beforehand.
