3 | ?? Allow -S /dev/md? - current complains subsequent not a/d/r | |

56eb10c0 NB |
5 | * new "Query" mode to subsume --detail and --examine. |
6 | --query or -Q, takes a device and tells if it is an MD device, | |
7 | and also tells in a raid superblock is found. | |
8 | ||
cd29a5c8 NB |
9 | * write proc.c to parse /proc/mdstat file, and maybe /proc/partitions too. |
10 | Build list of arrays: name, rebuild-percent | |
11 | ||
9a9dab36 | 12 | * --detail --scan to read mdadm.conf, and then iterate over these, |
cd29a5c8 NB |
13 | but assume --brief. --verbose can override |
14 | check each subdevice to see if it is in conf_get_devs. | |
15 | Warn if not. | |
16 | ||
17 | * Support multipath ... maybe... | |
18 | ||
19 | * --follow to syslog | |
20 | ||
21 | * --follow to move spares around | |
22 | ||
23 | * --follow to notice other events: | |
24 | rebuild started | |
25 | spare activated | |
26 | spare removed | |
27 | spare added | |

41 | one missing, one spare, insync DONE (--force) |
42 | - and for raid1 - some failed drives... (missing) | |
52826846 | 43 | |
82b27616 NB |
44 | - when RUN_ARRAY, make sure *_disks counts are right |
45 | ||
46 | - get --detail to extract extra stuff from superblock, | |
47 | like uuid DONE | |
cd29a5c8 | 48 | - --detail --brief to give a config file line DONE |

49 | - parse config file. DONE |
50 | - test... | |

9a9dab36 | 56 | - mdadm -S /dev/md0 /dev/md1 gives internal error FIXED |

62 | Assemble doesn't add spares. - DONE | |
63 | Create to allow "missing" name for devices. | |
64 | Create to accept "--force" for do exactly what is requested | |
65 | - get Assemble to upgrade devices if force flag. | |
66 | ARRAY lines in config file to have super_minor=n | |
67 | ARRAY lines in config file to have device=pattern, and only accept | |
68 | those devices | |
69 | If UUID given, insist on that | |
70 | If not, but super_minor given, require all found with that minor | |
71 | to have same uuid | |
72 | If only device given, all valid supers on those devices must have | |
73 | same uuid | |
74 | allow /dev/mdX as first argument before any options | |
75 | Possible --dry-run option for create and assemble--force | |
76 | ||
77 | Assemble to check that all devices mentioned in superblock | |
78 | are present. | |
79 | ||
80 | New mode: --Monitor (or --Follow) | |
81 | Periodically check status of all arrays (listed in config file). | |
82 | Log every event and apparent cause - or differences | |
83 | Email and alert - or run a program - for important events | |
84 | Move spares around if necessary. | |
85 | ||
86 | An Array line can have a spare-group= field that indicates that | |
87 | the array shares spares with other arrays with the same | |
88 | spare-group name. | |
89 | If an array has a failed and no spares, then check all other | |
90 | arrays in the spare group. If one has no failures and a spare, | |
91 | then consider that spare. | |
92 | Choose the smallest considered spare that is large enough. | |
93 | If there is one, then hot-remove it from it's home, and | |
94 | hot-add it to the array in question. | |

96 | --mail-to address | |
97 | --alert-handler program | |
98 | ||
99 | Will also extract information from /proc/mdstat if present, | |
100 | and consider 20% marks in rebuild as events. | |
101 | ||
102 | Events are: | |
103 | drive fails - causes mail to be sent | |
104 | rebuild started | |
105 | spare activated | |
106 | spare removed | |
cd29a5c8 | 107 | spare added |
