* 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>
* Fix problem with sector/KB size confuision for bitmap sizing.Neil Brown2006-05-153-7/+5

* Use O_DIRECT to read bitmap files.Neil Brown2006-05-153-21/+43
| | | | | | | | A pending patch to the kernel causes bitmap file updates to not go through the page cache, so O_DIRECT is needed to ensure that we read current data. Signed-off-by: Neil Brown <neilb@suse.de>
* [PATCH] Make sure update_super returns correct value.Neil Brown2006-04-282-4/+21
| | | | | | | | | | | | | | | | For 'force' and 'assemble', update_super must return true if anything was changed. Also fix a bug with wonly handling in super0.

* Fix alignment problem in version-1 superblocks.Neil Brown2006-04-072-1/+9
| | | | | | | | NOTE: This is an incompatable change affecting raid5 reshape. If you want to reshape a raid5 using version-1 superblocks, use 2.6.17-rc2 or later, and mdadm-2.4.1 or later. Signed-off-by: Neil Brown <neilb@suse.de>

* Don't try to get bitmap info on old kernels.Neil Brown2006-03-281-2/+4
| | | | | | | | .. this causes silly warnings. Unfortuantely there are 2.6 kernels which will still produce warnings. We cannot reliable detect those. Signed-off-by: Neil Brown <neilb@suse.de>

* Make scanning of /dev work even if it is a symlinkNeil Brown2006-03-271-1/+8
| | | | | | | | We generally don't want to follow symlinks in /dev, but if /dev itself is a symlink, we want to follow it. So nftw needs a bit of help. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow resize to backup to a file.Neil Brown2006-03-276-42/+104
| | | | | | | | | | To support resizing an array without a spare, mdadm now understands --backup-file= which should point to a file for storing a backup of critical data. This can be given to --grow which will create the file, or --assemble which will restore from the file if needed. Signed-off-by: Neil Brown <neilb@suse.de>
