LHN P4500G2 cannot add node to cluster

[GJHop]

Hi all,

Could you please assist me with the following issue?

I have a HPE Lefthand P4500G2 cluster that consists of 4 nodes.
Recently, after a node failure, I was forced to reinstall the node (with OS version 10.5.000.0149.0).
But now, I can’t add it back to the cluster. When I try to exchange or swap the node with the placeholder, I receive this message:

Insufficient space to make the requested change.

When reviewing the arrays on the node, I noticed that Array 1 differs in size compared to the other nodes.

Reinstalled node - Array 1: /dev/cciss/c0d1p2 DATA Partition Raid 5 2741.07 GB
Nodes in cluster - Array 1: /dev/cciss/c0d1p2 DATA Partition Raid 5 2741.08 GB

All of the nodes are running the same OS version: 10.5.000.0149.0

Could it be that the size difference of 10MB is the source of this problem?

This problem is solved.

After changing one of the volumes to thin provisioning, there was enough free space to add the node.
