| | | | | | | | | 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'krw2015-07-211-5/+5
| | | | | | | | | 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.

* Provide a function that handles the scheduling of work units. Thisjsing2013-05-211-22/+4

This is provided via a sd_scsi_wu_done hook, which enables work units to be restarted or otherwise modified before the SCSI xfer completion occurs. ok krw@

* sd_wu_pending is only decremented when scsi_done() or scsi_io_put() arejsing2013-03-291-4/+1
| | | | | | | | | called. As a result, factor out the the sd_sync check/wakeup code and move it to after the scsi_done() call in sr_scsi_done(). Perform the same sd_sync check/wakeup after scsi_io_put() calls (including the addition of some that were previously missed). ok krw@
* Rewrite the work unit handling code in the RAID 1/4/5/6 interrupt handlers.jsing2013-03-271-69/+52
| | | | | | | | | This simplifies the code and will allow for easier conversion to the workq based work unit completion routines. It also ensures that work units are always removed from the pending queue and that colliders are started, even in the event of an I/O failure. ok krw@

* Convert softraid(4) to new bio(4) status interface. This allows bioctl(8)jsing2012-01-221-2/+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 whichjsing2011-12-261-1/+3

* Determine the data offset using a variable specified within the softraidjsing2010-07-021-2/+2

* Add storage for the boot block and boot loader to the softraid metadata.jsing2010-03-261-2/+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@
