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.
