Datastore sizes changing

[mrsvo]

I have Dell EMC San.

VM-cluster in 5 hosts.

I razed Datastore size from 20 to 22 tb.

In VSphere size rased successful. But when VeaamBR makes backup of any vm size of cluster shrinks to 20Tb.

After clicking "refresh capacity information" on this datastore - ut's updates and displaying sixe 22Tb.

Then story continuing.

What should i do whit this issue?

In some cases refreshing the capacity on all hosts does not seem to work correctly from the GUI (neither from vCenter, not from the ESXi host directly). What worked for me in such cases was to run vmkfstools -V (please note the upper case "V") on each host for a refresh.

vmkfstools -V - rescans datastores for this host? Am i correct?

[a_p_]

Yes, vmkfstools -V performs a refresh of the VMFS volumes.

I've seen this is the hosts where running different versions, but doing a rescan and refresh capacity on each host in the GUI seems to work as well, we stopped resizing volumes and just add more.

Thx. It was really helpful for me.
