Max number of nodes in a PVE 3.2 cluster

[glena]

Hello,

I'm looking to build a larger cluster using PVE V3.2 with ceph and wanted to know what the max size is that I can go to.

We are currently looking at 18 nodes with:

- Two 8 core AMD CPUs
- 128Gig ram
- 2 smaller SAS disks for base OS
- 4 x 4gig sas drives as ceph OSDs. (dedicated to ceph and may expand to 8 4TB disks)
- 2 x 10GBit Ethernet nics bonded
- due to cost, the ceph journals will probably go on each spinner...

I had heard that the max cluster size for PVE was 16. Is this still the case? If so, I guess I need to split this into two clusters of 9 nodes each....

Thanks,

-Glen

I guess is still 16 but read this also

I left the (currently) last message there because I found that
<<Corosync has hardcoded maximum number of nodes to 64. It's also good to note, that officially supported is like 16 nodes, so no wonder 80 doesn't work.>>
