It should *not* be +considered stable and should be used primarily for testing. +The current "stable" version is 1.8.0. + +Release 1.8.1 supports different styles of superblocks (aka RAID metadata). +Two formats are currently supported + version 0.90.0 - the traditional Linux RAID superblock + version 1 - a new superblock which less useless information and some more + flexability. + +Version 1 supports more than 28 devices in an array, and RAID1 and greater over +devices larger than 2TB (though a 2TB RAID1 would take forever to resync!). + +mdadm 1.8.1 takes a different approach to creating arrays than +previous versions, though this is largely transparent. Instead of +giving the devices to the kernel and letting it "create" the array and +write out initial superblocks, mdadm 1.8.1 writes out the initial +superblocks itself, thus creating the array, and then asks the kernel +to assemble that array. + +Version 1 superblocks requires 2.6.10 or a recent 2.6.10-rc snapshot. + +Enhancements that are expected before this becomes 2.0.0: + + - mdassemble currently doesn't compile + - version 1 superblocks have room for a label, which currently isn't used. + Setting the label, and assembling arrays by label will be supported. + A label like "$HOSTNAME-root" could be the standard label for the device + containing the root filesystem for $HOSTNAME. + + +Development of mdadm is sponsored by CSE@UNSW: + The School of Computer Science and Engineering +at + The University of New South Wales + +NeilBrown 05 November 2004 + -- cgit
