VSAN Data store Error - no space left on device

Hi,

we are doing scp copy form one external ESXi to VxRail VSAN data store . when we tried SCP copy, VSAN data store doesn't allowed to copy the data due to permissions. so we have created a folder in VSAN Marvin data store and then we moved the couple of VM's successfully. when try move more VM's ( 3 Vm's of 150Gb , 250Gb and 1.5Tb were tried to copied in same folder under VSAN Data store and it failed.) through SCP then the error is coming no space left on Data store even though in VSAN data store 10TB of free space available.

Each ESXi in VxRAIL 4 node cluster have one drive of 3.84TB data drive and 400GB SDD Cache each.

Thanks in advance for your inputs.

Thank you,

Gopi Reddy

This behaviour is caused by VSAN's object storage handling.

"VSAN storage employs object-level storage, which is different from traditional block-level storage. The VSAN objects are managed through a storage policy which, for example, can allow for greater redundancy for some virtual machines over others. Because the reference in the VMDK file points to a VSAN DOM object, it cannot be copied through traditional means (SCP)."

You could use VMware Converter to do a V2V conversion of the source VM onto VSAN storage.

you shouldn't use SCP with vSAN, do a Storage vMotion instead!

Hi, Thanks for your response.

we can't use storage Vmotion, due to license issue in source ESXi.


we are able to SCP VM from external host to VSAN data store and copied sucessfully, but when tried multiple VM SCP in same folder, it failed " no space left" where as total space available is 9TB , data trying to copy is 2 TB, any resolution to this ?
