It is believed to work, and some testing does\nsupport this, but wider testing would be great for increasing my confidence.\n\nYou will need a version of mdadm newer than 2.3.1 to make use of raid5 growth.\n This is because mdadm need to take a copy of a \u0027critical section\u0027 at the\nstart of the array incase there is a crash at an awkward moment.  On restart,\nmdadm will restore the critical section and allow reshape to continue.\n\nI hope to release a 2.4-pre by early next week - it still needs a little more\npolishing.\n\nThis patch:\n\nPreviously the array of disk information was included in the raid5 \u0027conf\u0027\nstructure which was allocated to an appropriate size.

      "message": "[PATCH] md: remove personality numbering from md\n\nmd supports multiple different RAID level, each being implemented by a\n\u0027personality\u0027 (which is often in a separate module).\n\nThese personalities have fairly artificial \u0027numbers\u0027.  The numbers\nare use to:\n 1- provide an index into an array where the various personalities\n    are recorded\n 2- identify the module (via an alias) which implements are particular\n    personality.\n\nNeither of these uses really justify the existence of personality numbers.\nThe array can be replaced by a linked list which is searched (array lookup\nonly happens very rarely).  Module identification can be done using an alias\nbased on level rather than \u0027personality\u0027 number.\n\nThe current \u0027raid5\u0027 modules support two level (4 and 5) but only one\npersonality.  This slight awkwardness (which was handled in the mapping from\nlevel to personality) can be better handled by allowing raid5 to register 2\npersonalities.\n\nWith this change in place, the core md module does not need to have an\nexhaustive list of all possible personalities, so other personalities can be\nadded independently.\n\nThis patch also moves the check for chunksize being non-zero into the -\u003erun\nroutines for the personalities that need it, rather than having it in core-md.\n This has a side effect of allowing \u0027faulty\u0027 and \u0027linear\u0027 not to have a\nchunk-size set.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
