I'm not exaclty sure whether I understand the current situation.

Anyway, assuming that the host has sufficient free memory (RAM), you could change the memory reservation for the VM.
The swap file that gets created at power on has a size of configured RAM minus reservation, i.e. with reserving all memory the swap file won't require any disk space.

As mentioned, the swap file will be created at power on.

Do you receive an error message when you try to power on the VM?
Please post the exact message.

No space to create SWAP file. The VM simply does not power on

Hi,

I had the same problem from a customer, you have three options:

1- add another LUN or extend the existing.
2- if there are other VMs, move them to another datastore.
3- free up space in the datastore.


If you can't do any of this ... there are no solutions. To turn on the vm you need to have space.

I solved it by adding 1TB in the existing lun.

Delete stuff, if the datastore is full, the only way you can power-on a VM is by creating enough space so that the swap file can be created. Unless you fully reserve memory, as than a swap file would not be created. Either way, I would recommend at least 10-15% free space on a LUN to begin with. You should free up space ASAP, or add capacity to the datastore in some shape or form.

I already have one Iscsi server attached and a target added.  Will I be able to add another iSCSI server and a new target to increase space

Current situation is as below

Sure, you can add more targets. But wouldn't you just be able to add a new LUN to the existing target?
