142 | * The task of Assemble is to find a collection of |
143 | * devices that should (according to their superblocks) | |
144 | * form an array, and to give this collection to the MD driver. | |
145 | * In Linux-2.4 and later, this involves submitting a | |
64c4757e NB |
146 | * SET_ARRAY_INFO ioctl with no arg - to prepare |
147 | * the array - and then submit a number of | |
148 | * ADD_NEW_DISK ioctls to add disks into | |
149 | * the array. Finally RUN_ARRAY might | |
150 | * be submitted to start the array. | |
151 | * | |
152 | * Much of the work of Assemble is in finding and/or | |
153 | * checking the disks to make sure they look right. | |
154 | * | |
4b1ac34b | 155 | * If mddev is not set, then scan must be set and we |
64c4757e NB |
156 | * read through the config file for dev+uuid mapping |
157 | * We recurse, setting mddev, for each device that | |
158 | * - isn't running | |
4b1ac34b | 159 | * - has a valid uuid (or any uuid if !uuidset) |
64c4757e NB |
160 | * |
161 | * If mddev is set, we try to determine state of md. | |
162 | * check version - must be at least 0.90.0 | |
163 | * check kernel version. must be at least 2.4. | |
164 | * If not, we can possibly fall back on START_ARRAY | |
165 | * Try to GET_ARRAY_INFO. | |
166 | * If possible, give up | |
167 | * If not, try to STOP_ARRAY just to make sure | |
168 | * | |
169 | * If !uuidset and scan, look in conf-file for uuid | |
170 | * If not found, give up | |
b8a8ccf9 | 171 | * If !devlist and scan and uuidset, get list of devs from conf-file |
64c4757e NB |
172 | * |
173 | * For each device: | |
174 | * Check superblock - discard if bad | |
175 | * Check uuid (set if we don't have one) - discard if no match | |
5787fa49 | 176 | * Check superblock similarity if we have a superblock - discard if different |
4b1ac34b | 177 | * Record events, devicenum |
64c4757e | 178 | * This should give us a list of devices for the array |
4b1ac34b | 179 | * We should collect the most recent event number |
