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, | |
e0d19036 NB |
7 | and also tells in a raid superblock is found. |
8 | DONE | |
56eb10c0 | 9 | |
e0d19036 | 10 | * write mdstat.c to parse /proc/mdstat file |
cd29a5c8 | 11 | Build list of arrays: name, rebuild-percent |
e0d19036 | 12 | DONE |
cd29a5c8 | 13 | |
e0d19036 NB |
14 | * parse /proc/partitions and map major/minor into /dev/* names, |
15 | and use that for default DEVICE list ???? | |
16 | ||
17 | * --detail --scan to read /proc/mdstat, and then iterate over these, | |
cd29a5c8 NB |
18 | but assume --brief. --verbose can override |
19 | check each subdevice to see if it is in conf_get_devs. | |
20 | Warn if not. | |
e0d19036 | 21 | DONE, but don't warn yet... |

49 | - and for raid1 - some failed drives... (missing) | |
52826846 | 50 | |
82b27616 NB |
51 | - when RUN_ARRAY, make sure *_disks counts are right |
52 | ||
53 | - get --detail to extract extra stuff from superblock, | |
54 | like uuid DONE | |

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

103 | --mail-to address | |
104 | --alert-handler program | |
105 | ||
106 | Will also extract information from /proc/mdstat if present, | |
107 | and consider 20% marks in rebuild as events. | |
108 | ||
109 | Events are: | |
110 | drive fails - causes mail to be sent | |
111 | rebuild started | |
112 | spare activated | |
113 | spare removed | |
cd29a5c8 | 114 | spare added |
