| | | | | | | | | | | | | | | Similar to what was done for device_printfs in r347229. Convert g_print_bio() to a thin shim around g_format_bio(), which acts on an sbuf; documented in g_bio.9.

* spdx: initial adoption of licensing ID tags.Pedro F. Giffuni2017-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Initially, only tag files that use BSD 4-Clause "Original" license. RelNotes: yes Differential Revision: https://reviews.freebsd.org/D13133 Notes: svn path=/head/; revision=325966

* Import the gvinum work that have been done during and after Summer of Code 2007.Ulf Lilleengen2009-03-281-290/+599
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The work have been under testing and fixing since then, and it is mature enough to be put into HEAD for further testing. A lot have changed in this time, and here are the most important: - Gvinum now uses one single workerthread instead of one thread for each volume and each plex. The reason for this is that the previous scheme was very complex, and was the cause of many of the bugs discovered in gvinum. Instead, gvinum now uses one worker thread with an event queue, quite similar to what used in gmirror. - The rebuild/grow/initialize/parity check routines no longer runs in separate threads, but are run as regular I/O requests with special flags. This made it easier to support mounted growing and parity rebuild. - Support for growing striped and raid5-plexes, meaning that one can extend the volumes for these plex types in addition to the concat type. Also works while the volume is mounted. - Implementation of many of the missing commands from the old vinum: attach/detach, start (was partially implemented), stop (was partially implemented), concat, mirror, stripe, raid5 (shortcuts for creating volumes with one plex of these organizations). - The parity check and rebuild no longer goes between userland/kernel, meaning that the gvinum command will not stay and wait forever for the rebuild to finish. You can instead watch the status with the list command. - Many problems with gvinum have been reported since 5.x, and some has been hard to fix due to the complicated architecture. Hopefully, it should be more stable and better handle edge cases that previously made gvinum crash. - Failed drives no longer disappears entirely, but now leave behind a dummy drive that makes sure the original state is not forgotten in case the system is rebooted between drive failures/swaps. - Update manpage to reflect new commands and extend it with some examples.

* Re-vamp how I/O is handled in volumes and plexes.Lukas Ertl2004-09-181-2/+15
| | | | | | | | | | | | | Analogous to the drive level, give each volume and plex a worker thread that picks up and processes incoming and completed BIOs. This should fix the data corruption issues that have come up a few weeks ago and improve performance, especially of RAID5 plexes. The volume level needs a little work, though.
