suggested patch to let fio accept client ips from a file
A message that is not in the archive (sent off-list or not yet received): [email protected]
The following patch will allow fio to accept server IPs from a file. This is particularly useful when you have large numbers of fio servers (example: virtual machine guests) that participate in a test. To use this, simply use the --client option but instead of specifying a host name or IP, provide a pathname for a file containing a list of host names/addresses, one host per line.
