To use these options, modify USE_UNDOC_OPT=TRUE in iordef.h and then recompile.
|
|
For passing arguments to the executable for these options, use this format:
|
|
|
|
'-O option1=1,option2=0'
|
|
|
|
Options:
|
|
|
|
* fillTheFileSystem -- limits unnecessary output for showing performance, etc.
|
|
The command line '-w -k -m -i 123 -F -O fillTheFileSystem=5' has each task
|
|
creating (and keeping) 123 files, showing the time between every fifth file.
|
|
|
|
* includeDeleteTime -- use with '-O includeDeleteTime=1' to have time to
|
|
delete file included in write performance time. Note that if this file
|
|
is deleted after the write, there's nothing available for the read back
|
|
or checking.
|
|
|
|
* multiReRead -- use with '-i 5 -v -k -w -W -O multiReRead=1' to have 1 write
|
|
of file, followed by 4 reads w/data checking.
|
|
|
|
* NFS_serverCount -- use with other NFS_* options, -F, and -o to write/read
|
|
files across multiple NFS servers. Set the server count to > 0 to enable.
|
|
The format is: 'NFS_rootPath/NFS_serverName[0..NFS_serverCount-1]/outFile'.
|
|
Each file is written round-robin to a different NFS server.
|
|
|
|
* NFS_rootPath -- use with NFS_server* options for path to NFS servers.
|
|
|
|
* NFS_serverName -- ise with NFS_* options for NFS server prefix. Specific
|
|
NFS server number is appended to this name, e.g. nfs123.
|
|
|
|
* corruptFile -- corrupts file after writing for determining data-checking
|
|
reliability.
|
|
|
|
Note:
|
|
|
|
* cbif.c (Change Byte In File) is a simple utility to check the value of
|
|
a file offset; also allows changing a single byte at an offset.
