* | imsm: verify single sector mpb checksumsDan Williams2009-02-241-0/+11
| | | | | | | | | | | | | | If the mpb is only one sector do not skip the checksum verification. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* | imsm: fix mark_failure / introduce mark_missingDan Williams2009-02-241-19/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Actually, rename mark_failure to mark_missing and then implement the correct mark_failure which according to new documentation is to: 1/ Set the FAILED status bit 2/ Set IMSM_ORD_REBUILD to mark the disk out of sync 3/ Set map->failed_disk_num if this is the first failure detected failure (it is ~0 otherwise) Previously the assumption was that IMSM_ORD_REBUILD only appeared in map[1], so all routines that care about out-of-sync disks need to be updated.

* | imsm: introduce get_imsm_disk_slotDan Williams2009-02-241-27/+29

* | imsm: fix activate spare to ignore foreign disksDan Williams2009-02-231-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A foreign disk is one that all other drives believe is not-in-sync but does not have the 'failed' status bit set. This also reverts, because that commit is addressing the wrong problem. Ideally mdmon would kick "non-fresh" drives like the kernel does at native-md activation time, but that is too awkward to implement at the moment because mdadm owns container manipulations.

* | imsm: fixup container spare uuids by defaultDan Williams2009-02-231-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | Spares in the imsm case are marked with the "match-all" uuid of ffffffff-ffffffff-ffffffff-ffffffff. When performing incremental assembly we need to associate such devices with a populated container uuid. Also when performing --detail on a container with only spares present we can make an attempt to return a real uuid. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | As get_component_size() returns the number of used sectors of a device we need halve before pringing as K, and shift the value by 9, not 10, before passing to human_size.

* | imsm: fix failed disks are allowed back into the containerDan Williams2009-01-231-1/+4
| | | | | | | | | | | | | | | | | | Failed disks do not have valid serial numbers which means we will not pick up the 'failed' status bit from the metadata entry. Check for dl->index == -2 to prevent failed disks from being incorporated into the container. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* | Create: warn when a metadata format's platform components are missingDan Williams2009-01-204-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If the metadata handler can not find its platform support components then there is no way for it to verify that the raid configuration will be supported by the option-rom. Provide a generic method for metadata handlers to warn the user that the array they are about to create may not work as intended with a given platform.

* | imsm: enforce "all member disks must be members of all arrays"Dan Williams2009-01-201-29/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a key orom-compatibility constraint. A nice side effect is that it precludes the corner case of 'create' racing against 'spare activate' since the create will fail to convert a spare into an array member. At create time we check if this is the first member array in the container if it is than all disks are possible candidates, if it is not then only current members are permitted. A bit hairier is spare-activation handling in the presence of this constraint. It is difficult because spare handling is per array. The approach taken is to: 1/ check that a new spare can cover all defined arrays in the container 2/ ensure that partially assimilated spares are the first candidates when looking for a spare region to activate.

* | Assemble: fix busy detectionDan Williams2009-01-201-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use mddev_busy() as GET_ARRAY_INFO can succeed on 'clear' arrays. Ran into this after an encountering a case where mdadm -Ss ended in segfault (missing check for NULL return from map_by_devnum() in sles11:Manage.c). So, tried to stop the array by hand with echo clear > md/array_state, after which I could not reassemble since GET_ARRAY_INFO was succeeding. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
