5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Hi kovitking If you have the following error: The cause here is that manually updating the CVM's netmask will not update the value of 'external_subnet' in Zeus. This prevents the Data Services IP from communicating with the FSVMs and in turn not being able to mount the zpools. Note: The proper way to update CVM IP and/or subnet mask configuration is documented here. Please have the following information ready : 1) Verify the CVM IP and subnet via ifconfig. allssh "ifconfig eth0 | grep inet\ " Example: nutanix@cvm:~$ allssh "ifconfig eth0 | grep inet\ " ================== 10.58.85.39 ================= inet 10.58.85.39 netmask 255.255.255.0 broadcast 10.58.85.255 ================== 10.58.85.40 ================= inet 10.58.85.40 netmask 255.255.255.0 broadcast 10.58.85.255 ================== 10.58.85.41 ================= inet 10.58.85.41 netmask 255.255.255.0 broadcast 10.58.85.255 2) Verify what zookeeper has for the external_subnet: zeus_config_printer | grep ^extern
I would recommend to upgrade the cluster to AOS 5.10.7 or 5.11.1 because restarting genesis on a two node cluster with AOS 5.10.6 could lead to cluster instabillity. After Upgrade ty to Re-Deploy the File Server using Prism and let us know. Meanwhile I am searching for an alternate solution. Regs. Hi @AntonioG I’m follow KB https://portal.nutanix.com/page/documents/kbs/details/?targetId=kA00e000000CrNuCAK for upgrade two-node cluster. However, during manual upgrade is error as below message. 020-04-14 12:03:24 WARNING preupgrade_checks.py:815 Skipping replication factor check since cluster is stopped 2020-04-14 12:03:25 INFO multihome_utils.py:146 Cluster does not have multi homed CVMs 2020-04-14 12:03:25 ERROR preupgrade_checks.py:163 Cannot upgrade two node cluster when cluster has a leader fixed. Current leader svm id: 4. Try again after some time , Please refer KB 6396 2020-04-14 12:03:25 INFO preupgrade_checks.py:978 Cluster is stopped, skipping under-replication test 2
The ERROR message: Cannot upgrade two node cluster when cluster has a leader fixed… means that the cluster is under-replicated. Curator is responsible for kicking off replication for all extent groups that are not adequately replicated. A Curator full scan is needed to replicate the under-replicated data. Solution: Refer to KB 2826. Wait for cluster data to be rebalanced across nodes and Current Fault Tolerance to show 1. Once the curator scan has completed, run the pre-upgrade check again. It could be that it takes a couple of scans dependent on the number of underreplicated egroups. Regs. Antonio Hi @AntonioG Sorry, It’s just upgrade successfully. But the file server deployment still failed with same error.
Hi @AntonioG As your requested. File server creation step command result ncc output
Have you tried with a mathematically valid subnet? You specified your network as 172.16.1.0 / 255.255.254.0 The network address cannot be x.x.1.0 for this subnet mask. That “1” in your third octet is a 1 in the last bit, 00000001, but that bit is masked in this configuration since your subnet mask is functionally aaaaaaaa.bbbbbbbb.cccccccX.XXXXXXXX (X being the masked bits). 172.16.1.0 can only be the network address of a 255.255.255.0 subnet or smaller. I recognize correcting this configuration would mean shutting down the cluster and running the IP reconfig script. It also could mean some other adjustments to the network? Not sure what’s going on there. I wouldn’t be at all surprised if this is why your network validation fails in the creation process. Hi @JeremyJ You’re right. This is wrong. First of all, this node was configure as 255.255.255.0 subnet. Then our office has change network address to mask 23. So, I’ve run cluster reconfig and change zeus network address
@AntonioG As I told you this is non-production cluster. Just for PoC or internal testing in my office. So, I just used 2x1gb interfaces for connectivity.
@mandg Have you configure replication schedule? https://portal.nutanix.com/page/documents/kbs/details/?targetId=kA00e000000LMZRCA4
