* Remove lots of unnecessary white space.NeilBrown2013-06-19
| | | | | | | Now that I am using white-space mode in Emacs I can see all of this, and I don't like it :-) Signed-off-by: NeilBrown <neilb@suse.de>
* Create: default to bitmap=internal for large arrays.NeilBrown2013-03-05
| | | | | | | | Here, "large" means components are 100G or more. It is usually beneficial to have write-intent bitmaps on such arrays. They can be suppressed with --bitmap=none Signed-off-by: NeilBrown <neilb@suse.de>
* Discard devnum in favour of devnmNeilBrown2013-02-21
| | | | | | | | | | | | | | We widely use a "devnum" which is 0 or +ve for md%d devices and -ve for md_d%d devices. But I want to be able to use md_%s device names. So get rid of devnum (a number) and use devnm (a 32char string). eg. md0 md_d2 md_home Signed-off-by: NeilBrown <neilb@suse.de>
* Trivial bugfix and spelling fixes.Michael Tokarev2012-10-22
| | | | | | | | | And here's another trivial bugfix, now for spelling mistakes in various places, authred by Sergey Kirpichev (Cc'ed) and carried in debian mdadm package. Signed-off-by: NeilBrown <neilb@suse.de>
* Fix default size calculations that were recently broken.NeilBrown2012-08-13
| | | | | | | | | | commit d04f65f48c93e7e57cc3c1d70dd07d094dece717 Change the values for "max size" from -1 to 1. Messed up 's->size' - leaving it as '1' (MAX_SIZE) in some cases and causing the array reshape to fail. Signed-off-by: NeilBrown <neilb@suse.de>
* Use new 'struct shape' to pass args to BuildNeilBrown2012-07-09
| | | | Signed-off-by: NeilBrown <neilb@suse.de>
* Fix --build on 2.2 kernels :-)NeilBrown2012-07-09
| | | | | | | This code has clearly never been used because it isn't right. But let's fix it anyway. Signed-off-by: NeilBrown <neilb@suse.de>
* Change the values for "max size" from -1 to 1.NeilBrown2012-07-09
| | | | | | | | Both are impossible, and '1' allows size to be unsigned, which is neater. Also #define MAX_SIZE to be '1' to make it all more explicit. Signed-off-by: NeilBrown <neilb@suse.de>
* Change Build to take a struct contextNeilBrown2012-07-09
| | | | Signed-off-by: NeilBrown <neilb@suse.de>
* Introduce pr_err for printing error messages.NeilBrown2012-07-09
| | | | | | | 'pr_err("' is a lot shorter than 'fprintf(stderr, Name ": ' cont_err() is also available. Signed-off-by: NeilBrown <neilb@suse.de>
* Create: allow chunksize to be non-power-of-2.NeilBrown2011-05-10
| | | | | | | RAID0 has accepted chunksizes that are not a power of 2 since 2.6.30. So it time mdadm allowed that to be used. Signed-off-by: NeilBrown <neilb@suse.de>
* Improve type names for mddev_devNeilBrown2010-11-22
| | | | | | | | | Remove the _t pointer typedef and remove the _s suffix for the structure, These things do not help readability. Signed-off-by: NeilBrown <neilb@suse.de>
* Update copyright dates and remove references to @cse.unsw.edu.auNeilBrown2009-06-02
| | | | | | Also removed 'paper' addresses. Signed-off-by: NeilBrown <neilb@suse.de>

| * mdadm: allow build to use --sizePaul Clements2009-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the --size parameter for build operations. Without this, if you have a raid1, for instance, where the 2 disks are not the exact same size, and you need to build the array but one of the disks is not available right at the moment (maybe it's USB and it's unplugged, or maybe it's a network disk and it's unavailable), then you have to play some weird games to get the array to size correctly (that is, to the size of the smaller of the two components or less). There may be other uses for this too... -- Paul Signed-off-by: NeilBrown <neilb@suse.de>
* | wait_for improvement.NeilBrown2009-04-07
| | | | | | | | | | | | | | | | wait not only for the name to appear, but for it to refer to the correct device. Sometimes old symlinks left lying around can be confusing. Signed-off-by: NeilBrown <neilb@suse.de>
* | Wait for name to appear after create/assemble etc.NeilBrown2008-11-04
| | | | | | | | | | | | | | We don't really want mdadm to exit until udev has created the names in /dev. So wait. Signed-off-by: NeilBrown <neilb@suse.de>
* | Incremental: lock against multiple concurrent additions to an array.NeilBrown2008-11-04
| | | | | | | | | | | | | | In two devices are added via -I to one array at the same time, mdadm can get badly confused. Signed-off-by: NeilBrown <neilb@suse.de>
* | Always update mdadm/map when starting an array.NeilBrown2008-11-04
| | | | | | | | | | | | | | | | We previously only updated /var/run/mdadm/map when starting an array with --incremental. However we now make more use of that file (to pass the dev name to udev) so always update it. Signed-off-by: NeilBrown <neilb@suse.de>
* | mdopen: Introduce new rules for creating device name.NeilBrown2008-11-04
| | | | | | | | MORE CONTENT HERE
* | Delay creation of array devices for assemble/build/createNeilBrown2008-11-04
|/ | | | | | | | | | | | | We will shortly be feeding more information into the process of creating array devices, so delay the creation. Still open them early if the device already exists. This involves making sure the autof flag is in the right place so that it can be found at creation time. Also, Assemble, Build, and Create now always close 'mdfd'. Signed-off-by: NeilBrown <neilb@suse.de>
* Allow WRITEMOSTLY to be cleared on --readd using --readwrite.NeilBrown2008-10-25
| | | | | | | | Previously it was possible to set the WRITEMOSTLY flag when adding a device to an array, but not to clear the flag when re-adding. This is now possible with --readwrite. Signed-off-by: NeilBrown <neilb@suse.de>
* Remove spaces/tabs from ends of lines.Neil Brown2007-12-14

* Improve error message for adding bitmap to a level that cannot support it.Neil Brown2007-05-21
| | | | Also give error on --build if no devices given.
* Central calls to ioctl BLKGETSIZENeil Brown2006-12-14
| | | | Instead of opencoding the same thing everywhere.

* Limit size of bitmap to 2million chunks.Neil Brown2006-05-15
| | | | | | | | 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>
* Support bitmaps with raid10Neil Brown2005-11-22
| | | | | | And a couple of other little things Signed-off-by: Neil Brown <neilb@suse.de>
* Create version-4 bitmaps if kernel supports it.Neil Brown2005-10-11
| | | | | | | Version-3 bitmaps are host-endian. Version-4 are little-endian and so more portable. Signed-off-by: Neil Brown <neilb@suse.de>
* Assorted fixesNeil Brown2005-08-16
| | | | | | | | | Support "--build"ing arrays with bitmaps. hot-removal of bitmaps --re-add of drives recently removed. assorted extra tests Signed-off-by: Neil Brown <neilb@cse.unsw.edu.au>

* Add write-behind supportNeil Brown2005-08-09
| | | | | | | | Currently this includes --write-behind to set level of write-behind supported --write-mostly to flag devices as write-mostly. Signed-off-by: Neil Brown <neilb@cse.unsw.edu.au>
* Don't for a chunk-size when "build"ing a raid1Neil Brown2005-07-29
