HI,
I need to replace a switch in one of our datacenters, that is used by a couple of PVE nodes for almost anything (corosync, ZFS over iSCSI, node to node traffic for VMs etc.).
The replacement shouldn't take long, but still it may take a minute or so. For all the traffic except ZFS over iSCSI this seems trivial, a short interruption won't cause major issues. But at least from what I have read, ZFS over ISCSI connections won't recover from network interruptions.
[small edit]: One of the affected PVE nodes acts as the ZFS over ISCSI storage provider.
So two questions:
1. is it true, that ZFS over ISCSI can't handle (brief) network outages?
2. Is there any other way but to shut down all iSCSI consumers, replace the switch and turn the consumers on again?
Thanks
Udo
