* No need to rescan chunks in each discipline to find appropriatekrw2016-04-121-11/+1

* Enable creation of softraid volumes using disks with non-512 bytekrw2016-04-041-1/+11
| | | | | | | | | sectors. Volumes created will present a sector size equal to the largest sector size of the constituent disks. Softraid Metadata version cranks to 6 due to new field. ok jsing@ with tweaks that will follow soon.
* A few more daddr_t fixes. Rename 'phys_off' variables to 'offset'krw2015-07-211-15/+15
| | | | | | | | | since they are now relative to chunks. Use 'blkno' as normal variable name for daddr_t items rather than mix of 'blkno, blk, offset. Change field name ssd_data_offset to ssd_data_blkno since it is a block and not byte quantity. No intentional functional change.

* Stop adding and subtracting data offset. Just keep to chunk relativekrw2015-07-191-3/+2
| | | | | | | | | block offsets until actual i/o is constructed and needs the physical offset. Eliminate a number of <<DEV_BSIZE shifts as a bonus. No intentional functional change. Fixed and ok jsing@

| | | | | | 512-byte-block information to int64_t, the underlying type of daddr_t at the moment. No change to .o files. Removal of now unneeded (long long) casts is next.
* Fix RAID levels 0, 4, 5, and 6 with partitions larger than 2TB.reyk2013-11-051-2/+3
| | | | | | | | | A 64bit bit operation with the 32bit strip size could overflow and result in ridiculously small volumes when using large partitions (eg. 4x 3TB in RAID 5 resulted in a ~2TB volume). It is fixed by casting the strip size to an unsigned 64bit value. ok tedu@ millert@ deraadt@
* Sprinkle (long long) casts where %lld is being used to print daddr_tkrw2013-11-011-4/+6

* Convert softraid(4) to new bio(4) status interface. This allows bioctl(8)jsing2012-01-221-3/+4
| | | | | | to provide useful feedback, rather than reporting an ioctl failure and leaving the user to consult dmesg. For now we continue to print most things to the console, even if the message is a result of an ioctl.
* Provide default set chunk state and set volume state functions whichjsing2011-12-261-111/+1

* Add storage for the boot block and boot loader to the softraid metadata.jsing2010-03-261-3/+2
| | | | | | | | | | | | | Also add a new optional metadata type for boot data. This is the first step (of many) towards being able to boot from softraid volumes. WARNING: This version of the softraid metadata is not compatible with previous versions. As a result, any softraid volumes created with older kernels will not assemble. Data on existing softraid volumes should be backed up before upgrading. The volume should then be recreated and the data restored. ok marco@

* Move the discipline initialisation code into discipline specific functions,jsing2009-05-111-2/+36

| | | | | | | | | | | | | | | | that caused illegal checksums. The new metadata code is more or less ready to deal with other vendor's metadata formats. While here clean up the name space. Fix thib's pool mess by adding removing bad flags in interrupt context. tested on macppc, amd64, i386, sparc64 & hppa sparc64 has issues with crypto however those do not seem to be softraid specific. help from okan@ ckuethe@ Will Backman and others
