Hello,
I receive many emails with this error:
The 9 node cluster worked very well from a year but now I added VMs (120 Vms now) and I think this is due to a timeout with zfs listing on the receiving node.
The backup node contains all the replicas and does nothing (no runningVMs):
When I try the command
sometime the output is very fast and I think it is cached, But sometime it takes 5-10 seconds.
I think this causes the random replication problem.
Is there a way to improve caching? I have now two logs ssd but I can use them for something else
