→ Applies to: SynetoOS 5.x

IMPORTANT

In this specific scenario, no new VMDK is added to the virtual machine. Instead, the procedure involves changing the size of the existing virtual disk (VMDK) from the VMware ESXi interface.

Step 1. Shutdown all VMs

Step 2. Increase VMDK size ("How to increase VMDK size in VMware ESXi")

Step 3. Connect to SynetoOS appliance via SSH as admin (replace <your_ip_address_or_hostname> with the correct ip/hostname)

ssh admin@<your_ip_address_or_hostname>

Step 4. Get root privileges

sudo su -

Step 5. Check if additional disk space is available

config disk show

EXAMPLE OUTPUT

[root@syneto-os-5 admin]# config disk show 

Type    Size    Pos.    Enc.    Name    Other

SSD     80.00GB 0:0:0:0 scsi-36000c2939ba28228bd4a823689f92f42  S/N: 6000c2939ba28228bd4a823689f92f42 VMware VMware Virtual disk

SSD     100.00GB        0:0:1:0 scsi-36000c299ee9d58b459164bb726b7fbf7  S/N: 6000c299ee9d58b459164bb726b7fbf7 VMware VMware Virtual disk

 

Save the identifier of the disk on which the space expansion was performed. 

In this case, it's the second disk, identified as: scsi-36000c299ee9d58b459164bb726b7fbf7.

This information will be required in Step 7 (replacing <disk_name>).

Step 6. Enable autoexpand (replace <pool_name> with the correct information)

zpool set autoexpand=on <pool_name>

EXAMPLE

zpool set autoexpand=on flash
zpool set autoexpand=on hybrid

Step 7. Expand the storage pool (replace <pool_name> and <disk_name> with the correct information)

zpool online -e <pool_name> <disk_name>

EXAMPLE

zpool online -e flash scsi-36000c299ee9d58b459164bb726b7fbf7
zpool online -e hybrid scsi-36000c299ee9d58b459164bb726b7fbf7

Step 8. Check if the operation is completed

zpool list

EXAMPLE

[root@syneto-os-ec support]# zpool list
