Currently the only\nshape change that is supported is added a device, but it is envisioned that\nchanging the chunksize and layout will also be supported, as well as changing\nthe level (e.g. 1-\u003e5, 5-\u003e6).\n\nThe reshape process naturally has to move all of the data in the array, and so\nshould be used with caution. 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. This makes it awkward\nto change the size of that array.
