.\" -*- nroff -*- .TH MDASSEMBLE 8 "" v3.0-rc1 .SH NAME mdassemble \- assemble MD devices .I aka Linux Software RAID .SH SYNOPSIS .BI mdassemble .SH DESCRIPTION .B mdassemble is a tiny program that can be used to assemble MD devices inside an initial ramdisk (initrd) or initramfs; it is meant to replace the in-kernel automatic raid detection and activation. It can be built statically and linked against lightweight libc alternatives, like .B dietlibc, .B klibc or .B uClibc. .SH USAGE Invoking .B mdassemble has the same effect as invoking .B mdadm \-\-assemble \-\-scan. .PP Invoking .B mdassemble a second time will make all defined arrays readwrite, this is useful if using the .B start_ro module parameter. .SH OPTIONS There are no options to .B mdassemble. .SH FILES .SS /etc/mdadm.conf The config file lists which devices may be scanned to see if they contain MD super block, and gives identifying information (e.g. UUID) about known MD arrays. See .BR mdadm.conf (5) for more details. .B mdassemble supports all configuration parameters defined in .B mdadm.conf with the exception of .B auto= which is supported only if mdadm was built with the .B \-DMDASSEMBLE_AUTO define. .SH SEE ALSO .PP .BR mdadm (8), .BR mdadm.conf (5), .BR md (4), .BR diet (1).
