UNRELIABLEFS.CONF(5) File Formats Manual UNRELIABLEFS.CONF(5) NAME unreliablefs.conf -- format of the configuration file used by unreliablefs(1) DESCRIPTION The configuration file format is quite simple. Sections are delimited by square brackets: [Section] And options within brackets sections are simple key value pairs: Option = Value OPTIONS Per-fault-injection customizable variables are specified within sec- tions with section names matching the fault-injection name. Supported fault injections are: errinj_noop File operation replaced with no-op. errinj_kill_caller Send SIGKILL signal to a process that invoked file operation. errinj_errno Set random errno. errno(2) limited by supported errno's. errinj_slowdown File operation slowdown for nanoseconds specified by duration parameter. The options are: op_regexp Sets the regular expression that matches file operation for what fault injection is applicable. Option uses format of reg- ular expressions described in re_format(7). POSIX Extended Regular Expression syntax is supported and regular expressions do not differentiate case. path_regexp Sets the regular expression that matches paths where fault in- jection is applicable. Option uses format of regular expres- sions described in re_format(7). POSIX Extended Regular Ex- pression syntax is supported and regular expressions do not differentiate case. probability Sets the probability in percents. Probability equal to 0 means that error injection will never happen. Probability equal to 100 means that error injection will happen on each file opera- tion. duration Sets the duration of file operation slowdown. Applicable to errinj_slowdown only. EXAMPLES [errinj_noop] path_regexp = .* op_regexp = .* probability = 70 [errinj_errno] path_regexp = *.xlog probability = 4 SEE ALSO unreliablefs(1), errno(2), syslog(3), re_format(7) AUTHORS The unreliablefs(1) utility was written by Sergey Bronnikov.
