Hello,
I’m experiencing an issue on an XCP-ng cluster using XOSTOR.
Environment:
- 3-node XCP-ng cluster
- XOSTOR distributed storage (2x2Tob nvme on each host)
- XOA for management
- Management network 1Gb/s
- Storage Network 10Gb/s
MTU 1500 everywhere (no jumbo frames)
So during VM migrations, creation, destroy XOA loses connection to my host pool, VMs keep running normally Hosts remain reachable (SSH / HTTPS / ping OK), Connection comes back after some time 30s to 1min.
Observations:
- No significant CPU or RAM saturation
- No obvious disk latency issues (iostat looks normal)
- No errors reported on NICs
- xapi process remains active (no crash or freeze)
- The problem is intermittent and seems random.
- i've monitored nic with iftop and i see no bandwith bottleneck et and can see that XOSTOR is using 10gb network only.
Has anyone experienced similar behavior with XOSTOR? And how to Fix it ?
Thanks in advance for your help.
