Even after I exposed the shadow copy volume, the same behavior. Please refer to my earlier comment on how i resolved it.
Thanks for the response @Cheong00 .
SMB share mount on windows 10 client does not show previous versions
Hello,
Good Morning.
I have a cluster with 2 windows 2019 core OS and have created a file server role and have a couple of SMB shares created on it.
Created shadow copies with following diskshadow commands
set context persistent nowriters
set metadata c:\example.cab
set verbose on
begin backup
add volume f: alias datavolumeshadow
create
end backup
End of script
DISKSHADOW> list shadows all
Querying all shadow copies on the computer ...

When I mounted the drive on the windows 10 client, I could not see the previous versions.
I have done a similar experiment on windows 2019 standard edition and I see it working.
Is there anything I need to enable in core OS?
Any input on this would be greatly appreciated. Would any logs give a clue.

EDIT: "Expose" command is for other purpose.

2021-03-22T09:35:36.567+00:00 Hi Anne,
I could find out the reason for this behavior, with diskshadow commands, the ClientAccessible attribute was not set.
When I created snapshots using the following powershell script, I could set the ClientAccessible attribute while taking snapshots.
get existing shadow copies
$shadow = get-wmiobject win32_shadowcopy
"There are {0} shadow copies on this sytem" -f $shadow.count
""get static method
$class=[WMICLASS]"root\cimv2:win32_shadowcopy"
create a new shadow copy
"Creating a new shadow copy"
$class.create("C:\", "ClientAccessible")Count again
$shadow = get-wmiobject win32_shadowcopy
"There are now {0} shadow copies on this sytem" -f $shadow.countDISKSHADOW> list shadows all
