* Uclibc has deprecated 'random' so use 'rand' instead.Neil Brown2006-05-291-0/+3
| | | | | | | | | | | glibc says of rand Do not use this function in applications intended to be portable when good randomness is needed. Go figure... Signed-off-by: Neil Brown <neilb@suse.de>

| | | | | | | | | fix for another srict-aliasing problem, you can typecast a reference to a void pointer to anything, you cannot typecast a reference to a struct. From: Luca Berra <bluca@vodka.it> Signed-off-by: Neil Brown <neilb@suse.de>

* Support --auto-update-homehostNeil Brown2006-05-264-3/+60
| | | | | | | | | This can be used to bootstrape homehost tagging. If no arrays are found that are tagged, we look for any array and tag it. Signed-off-by: Neil Brown <neilb@suse.de>

* Never remove device nodes of active devices.Neil Brown2006-05-261-1/+3
| | | | | | This is just too risky. Signed-off-by: Neil Brown <neilb@suse.de>
* Improve names reported by --examine --briefNeil Brown2006-05-262-4/+20
| | | | | | | Instead of depending (too much) on what is in /dev, we make names based on the content of the superblock. Signed-off-by: Neil Brown <neilb@suse.de>

* Initial implementation of auto-assemblyNeil Brown2006-05-263-35/+117
| | | | | | This basically works, but needs various improvements and some tests. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow autoassembly to choose it's own name for the array.Neil Brown2006-05-232-20/+33
| | | | | | | | | This cannot be used yet, but it is working towards auto-assembly. When auto-assembling an array, we make a name in /dev/md/ giving a number (from the peferred minor) or name (from set-name). Signed-off-by: Neil Brown <neilb@suse.de>
* When assembly arrays using incomplete detail, prefer arrays built for this host.Neil Brown2006-05-234-5/+59
| | | | | | | | i.e. if assembling with --name or --super-minor, then if we find two different arrays with the same apparent identity, and one was built for 'this' host, then prefer that one instead of giving up in disgust. Signed-off-by: Neil Brown <neilb@suse.de>
* Reorganise Assemble code somewhat.Neil Brown2006-05-232-7/+31
| | | | | | | | | | | We make sure all devices can are consistent before doing any --update This saves us from updating some but not all of an array, and then aborting. It also means we can backtrack on out decisions, which we might want to do later. Signed-off-by: Neil Brown <neilb@suse.de>

* Make homehost information appear in superblock.Neil Brown2006-05-1911-14/+721
| | | | | | | | When an array is created, if the homehost is know, the superblock gets it, either in the uuid, (via sha1) or in the name field. Signed-off-by: Neil Brown <neilb@suse.de>

* New flag --no-degradedNeil Brown2006-05-195-30/+63
| | | | | | | | | Use to avoid starting arrays if there are fewer devices available than last time the array was started. This is only needed with --scan, as with --scan, that behaviour is the default. Signed-off-by: Neil Brown <neilb@suse.de>

* Arrange the 'auto' setting in mdadm.conf can choose default type.Neil Brown2006-05-164-57/+89
| | | | | | | | | | | | So when you say auto=md or auto=part in mdadm.conf, it give a preference for type of array, but standard name will override. But --auto=md is more insistant. FIXME I'm not at all happy about handling of names that already exist. I don't think that should be removed if the device is active. Signed-off-by: Neil Brown <neilb@suse.de>

* When updating uuid, update the bitmap as well - internal bitmaps.Neil Brown2006-05-162-9/+82

* Limit size of bitmap to 2million chunks.Neil Brown2006-05-157-9/+20
| | | | | | | | When creating a file bitmap, choose a default size that results in fewer than 2^21 chunks. Without this kmalloc failure in the kernel becomes likely. Signed-off-by: Neil Brown <neilb@suse.de>

* Use O_DIRECT to read bitmap files.Neil Brown2006-05-153-21/+43
