Virtual RDM and Backup Proxy Hotadd

Post by seizurebot »

Hello,

Just a (hopefully) quick question which I could not find a definitive answer online:

I am running B&R Community Edition Ver 10 and I have one ESXI 6.5 host with 4 VMs, one of these VMs is a linux OS that I have recently configured as a backup proxy and one VM has a large ~55TB drive. Unfortunately I thick-provisioned this 55TB and now my backups fail because esxi believes the datastore to be full. I am in the process of moving this large vmdk to a virtual-mode RDM.

A) Will my new backup proxy be able to hotadd this virtual RDM?
B) If not should I expand this large datastore using spare disks to get the 1-2TB needed to get my backups working again?
C) If not either of the above will moving the working dir of the VM work to get the snapshots stored elsewhere?

I appreciate any insights,

Hi.
Answer to A) is "Yes".
As for the B) its a good practice to keep at least 10% virtual disk size free on the datastore for snapshots.
/Cheers!

Thanks for confirming :)

I'm going to go vRDM in the next few days.
