* Fix autoassemble for stack arrays.Neil Brown2008-05-201-0/+23
| | | | | | | | If you have stacked arrays, then mdadm -As --homehost=fred should work but doesn't. It gets into an infinite loop! So write some tests, and fix the bugs.
* Don't try the auto-detect test when md_mod is a moduleNeil Brown2008-05-151-0/+7
| | | | ....as this cannot work.
* Enhance raid4 support: --assemble and --monitor wasn't quite happy with it.Doug Ledford2007-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | From: Doug Ledford <dledford@redhat.com> This one actually does a couple things. Mainly related to raid4, but kinda touches other raid levels some. When creating a raid4 array, treat it like a raid5 array in that we create it in degraded mode by default and add the last disk as a spare. Besides speeding things up, this has a second effect that it makes mdadm more consistent. In order to create a degraded raid5 array, you need only passing missing as one of the devices. For a degraded raid4 array, prior to this patch, you must pass assume-clean or else it refuses to create the array. Even force won't make it work without assume-clean. With the patch, raid4 behaves identical to raid5. Separate from that, the monitor functionality completely ignores raid4 arrays. That seems to stem from the code that checks to see if the array is part of a long list of types. It seems easier to check which array types *aren't* redundant instead of listing the ones that are redundant and missing some of them. This makes the monitor service actually watch raid4 arrays.
* Add --auto-detect for in-kernel autodetect.Neil Brown2007-05-211-0/+25
| | | | This is equivalent to raidautorun that some distros provide.
* Update tests and add linear-addNeil Brown2007-05-215-7/+29
| | | | | | Update the testing scripts to allow for new space calculations for space for bitmaps. Add a test script for adding devices to linear arrays.
* Fix handling of negative bitmap offsets on 64bit hosts.Neil Brown2007-05-212-0/+0
| | | | | The bitmap offset is a signed 32bit number, so casting to (long) isn't sufficient. We must cast to (int32_t).
* Fix and test --update=uuidNeil Brown2006-12-141-0/+82
| | | | A number of odd bugs here, but now we have a regression test as well.
* Make Assemble/Force work on raid6 with 2 missing devices.Neil Brown2006-12-141-0/+0
| | | | | | Previously it onl worked when one missing device. Also split the "force" update_super method into two and it is really serving two functions.
