| | | | | | | | | | | | | | | | | | | | | | | | | | | Dump the orom capabilities and hardware disk configuration. This code relies on the name of scsi_host objects to determine the hardware port number. Hopefully this information is stable... Signed-off-by: Dan Williams <dan.j.williams@intel.com>
| * | introduce --detail-platform to display platform raid capabilitiesDan Williams2008-12-089-3/+89
| | | | | | | | | | | | | | | | | | | | | Metadata formats like imsm work in concert with platform firmware and hardware, so provide a way for mdadm to display this info to the user. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
| * | imsm: validate arrays being created against firmware capabilitiesDan Williams2008-12-083-14/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These checks are only enabled when platform support for imsm is found, i.e. ahci driver is loaded and talking to an Intel(R) controller, and the option rom header is located. They can be turned off by setting the environment variable IMSM_NO_PLATFORM to 1. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The option-rom advertises its capabilities in a data structure located in the platform ROM region 0xc0000-0xf0000. Attempt to detect the option-rom and limit array creation to the platform's capabilities. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This provides at least a kernel bug compatible method of scanning for an adapter-rom. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We may be creating on spare disks in which case we need to know which disk goes in which slot. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
| * | imsm: correct start offset handling at create timeDan Williams2008-12-081-22/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | imsm metadata requires all members of a raid volume to start at the same offset. So, incrementally build a composite disk from all the candidates passed to ->validate_geometry. After each disk is added merge the extents and search for a common start offset that satisfies the requested raid device size. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | When chunksize is 0 in the raid1 case we need to use info_to_blocks_per_member() to calculate the array size. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for some arrays to be created e.g. by initrd, and so not get mentioned in /var/run/mdadm/map. As "-I" depends on things being listed in 'map', we create it by scanning all devices if it doesn't exist. Signed-off-by: NeilBrown <neilb@suse.de>
| * | Assemble: set stripe_cache_size properly when restarting a reshape.NeilBrown2008-12-181-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | Reshape with large chunk size can require a large stripe_cache. We make this work when starting the reshape but not when restarting at assemble time. So fix that. Signed-off-by: NeilBrown <neilb@suse.de>
| * | Assemble: don't assume array is 'clean' unless all devices think it is.NeilBrown2008-12-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This is only significant for --assemble --force where some old devices might be included into the array. If anything looks like it isn't clean, the kernel will not allow a degraded array to be started. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | If any superblocks in a confused array had an event count of 0, "mdadm -Af" would not update the event counts to assemble the array. I don't remember why that text is there, and it has caused at least one situation to be difficult to recover from. So remove the test. --force means --force! Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | 1/ When truncating the space reserved for the metadata round down to an even numbered sector count to avoid an off-by-one error when sysfs_add_disk rounds up. 2/ Set the current metadata parameter block size as a floor.

* | Assemble: don't auto-assemble if any arrays are listed in mdadm.confNeilBrown2008-11-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto-assembly and planned assembly don't really work well together, it can be confusing. In particular in mkinitrd or similar creates an mdadm.conf to assemble a particular array, we shouldn't go assembling any other arrays as well. If you want auto assembly, you need to give mdadm a config file with no ARRAY lines. mdadm -Ascpartitions can do this. Signed-off-by: NeilBrown <neilb@suse.de>
* | mdmon: pass symbolic name to mdmon instead of device name.NeilBrown2008-11-204-9/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that names in /dev are usually created (eventually) by udev, it isn't really safe to rely in finding a name in /dev to pass to mdmon to identify which array to monitor. And it isn't really necessary to have a name in /dev. So just pass the symbolic name, e.g. md127 or md123. Change util.c to pass that name, and change mdmon to process the name sensibly.
