Damal, there is no need for re-transmitting. How asynchronous NFS3 writes actually work has been defined in "RFC 1813 - NFS Version 3 Protocol Specification" (google for it; can't post links here). The key is the COMMIT mechanism.
I would request you to please explain me the following which are related to Coherent cache and number of disks in disk pool in Isilon :
1. How Isilons/OneFS forms coherent caches (READ/WRITE) across all the nodes which are part of the same cluster
2. Why the number of disks in a (disk pool = 6disks per node, per node pool up to 40 nodes ) disk pool is limited with 6 disk drives only.
Thanks in advance.
Can you take a look at the attached output for the isi statistics drive --top --long -nall --orderby=OpsIn. I see the Queued I/O is >1. Does it mention we need to add few more nodes to pool, or any other point you want to add on the output
Its a NL400 node running on OneFS 184.108.40.206
