127 | * The task of Assemble is to find a collection of |
128 | * devices that should (according to their superblocks) | |
129 | * form an array, and to give this collection to the MD driver. | |
130 | * In Linux-2.4 and later, this involves submitting a | |
64c4757e NB |
131 | * SET_ARRAY_INFO ioctl with no arg - to prepare |
132 | * the array - and then submit a number of | |
133 | * ADD_NEW_DISK ioctls to add disks into | |
134 | * the array. Finally RUN_ARRAY might | |
135 | * be submitted to start the array. | |
136 | * | |
137 | * Much of the work of Assemble is in finding and/or | |
138 | * checking the disks to make sure they look right. | |
139 | * | |
4b1ac34b | 140 | * If mddev is not set, then scan must be set and we |
64c4757e NB |
141 | * read through the config file for dev+uuid mapping |
142 | * We recurse, setting mddev, for each device that | |
143 | * - isn't running | |
4b1ac34b | 144 | * - has a valid uuid (or any uuid if !uuidset) |
64c4757e NB |
145 | * |
146 | * If mddev is set, we try to determine state of md. | |
147 | * check version - must be at least 0.90.0 | |
148 | * check kernel version. must be at least 2.4. | |
149 | * If not, we can possibly fall back on START_ARRAY | |
150 | * Try to GET_ARRAY_INFO. | |
151 | * If possible, give up | |
152 | * If not, try to STOP_ARRAY just to make sure | |
153 | * | |
154 | * If !uuidset and scan, look in conf-file for uuid | |
155 | * If not found, give up | |
b8a8ccf9 | 156 | * If !devlist and scan and uuidset, get list of devs from conf-file |
64c4757e NB |
157 | * |
158 | * For each device: | |
159 | * Check superblock - discard if bad | |
160 | * Check uuid (set if we don't have one) - discard if no match | |
5787fa49 | 161 | * Check superblock similarity if we have a superblock - discard if different |
4b1ac34b | 162 | * Record events, devicenum |
64c4757e | 163 | * This should give us a list of devices for the array |
4b1ac34b | 164 | * We should collect the most recent event number |

172 | * foreach device with recent events : ADD_NEW_DISK | |
173 | * if runstop == 1 || "enough" disks and runstop==0 -> RUN_ARRAY | |
