Pseudo devices like vnd and cgd can be opened but may still need some configuration. Ignore these quietly.

2016-01-04Fix dump on raid.mlelstv
- offset dump by RF_PROTECTED_SECTORS (thanks oster@ for noticing) - call component dump function with byte count instead of block count - return -1 instead of errno values in dk_size for error conditions. There are still issues with dumping. - the raid device must be open, neither reading the disklabel nor flushing the component labels in rfmarkdirty is possible when dumping. - dumping to a wedge component fails because the wedge driver only allows dumping to swap partitions, not raid partitions.
2016-01-03refactor driver to use common code in dksubr.mlelstv
2016-01-02No longer detach opened device directly in RAIDFRAME_SHUTDOWN ioctl,mlelstv
instead just mark the device for shutdown and detach on last close. Also don't manually print the detached message but leave this to config_detach(). This avoids a duplicate message when shutting down.

2015-12-26If the "finalizer" should fail to register for any reason, just reportpgoyette
the situation (as a WARNING) and continue. Don't return the error code to the caller. Failure to register should not really happen - if it does, all we really lose is auto-configuration of raid-sets.

2015-12-26Modularize the raidframe driver, including rework of the unit attachpgoyette
code to permit detaching (and possible module unloading). Also, convert tsleep()/wakeup() locking to use cv_wait_sig()/cv_broadcast(). Tested in non-modular, modular-builtin, and modular-loaded-at-runtime environments.

2015-01-02We have three sets of DTYPE_ constants in the kernel:christos
altq Drop Type disklabel Disk Type file Descriptor Type (not to mention constants that contain the string DTYPE). Let's make them two, by changing the disklabel one to be DisK TYPE since the other disklabel constants seem to do that. Not many userland programs use these constants (and the ones that they do are mostly in ifdefs). They will be fixed shortly.
2014-12-31make more drivers use disk_ioctl, and add a dev parameter to it so thatchristos
we can merge the "easy" disklabel ioctls to it. Ultimately all this will go do dk_ioctl once all the drivers have been converted.

2014-12-31disk_blocksize and disk_set_info relay the same informationmlelstv
to the disk subsystem. Make disk_set_info also set blocksize shift values. Remove every call to disk_blocksize. Keep disk_blocksize for ABI compatibility, make it also set dg_secsize.

2014-11-14Adjust comment to reflect reality. (5th arg, not 4th)oster
2014-11-14Fix a long-standing bug related to rebooting while aoster
reconstruct-to-spare is underway but not yet complete. The issue was that a component was being marked as a used_spare when the rebuild started, not when the rebuild was actually finished. Marking it as a used_spare meant that the component label on the spare was being updated such that after a reboot the component would be considered up-to-date, regardless of whether the rebuild actually completed! This fix includes: 1) Add an additional state "rf_ds_rebuilding_spare" which is used to denote that a spare is currently being rebuilt from the live components. 2) Update the comments on the disk states, which were out-of-sync with reality. 3) When rebuilding to a spare component, that spare now enters the state rf_ds_rebuilding_spare instead of the state rf_ds_used_spare. 4) When the rebuild is actually complete then the spare component enters the rf_ds_used_spare state. rf_ds_used_spare is now used exclusively for the case where the rebuilding to the spare has completed successfully. XXX: Someday we need to teach raidctl(8) about this new state, and take out the backwards compatibility code in rf_netbsdkintf.c (see RAIDFRAME_GET_INFO in raidioctl()). For today, this fix needs to be generic enough that it can get backported without major grief. XXX: Needs pullup to netbsd-5*, netbsd-6*, and netbsd-7 Fixes PR#49244.

I've set them all to nodiscard. Some of them (wd, dk, vnd, ld, raidframe, maybe cgd) should be implemented for real.
2014-06-14Change dk_lookup() to return an anonymous vnode not associated withhannken
any file system. Change all consumers of dk_lookup() to get the device from "v_rdev" instead of VOP_GETATTR() as specfs does not support VOP_GETATTR(). Devices obtained with dk_lookup() will no longer disappear on forced unmounts. Fix for PR kern/48849 (root mirror raid fails on shutdown) Welcome to 6.99.44
2014-05-12restore defaulting to the 'a' partition for booting with root on raid aschristos
it was before, and explain why we do things this way.
2014-05-08Revert default strategy change from 1.298 (which has since moved).jakllsch
Reverting to "fcfs" nearly doubles the speed of sequential reads from a level-1 RAID (previously using the default of "priocscan"). Needs pullup via patch for netbsd-6.
2014-04-03Add a "soft" root option, leaving the current default as "force root", sochristos
as not to break existing configurations.
2014-04-03Fix bugs in raidframe + wedge and root interaction:christos
1. Don't call cpu_rootconf() just to setup booted_device. Calling cpu_rootconf() multiple times can have nasty side effects (aside from printing root device twice). Instead for those who have it, call cpu_bootconf() which is intended just for that. 2. If the raid component devices are wedges, then matching the booted_device against the wedges will never work; match instead on the wedges parent. XXX: perhaps should keep looking if the parent is a wedge too?
2014-04-02If we are autoconfiguring root, then only change the booted_device ifchristos
we booted from one of the components of the root raid set. This allows us to boot from other media, without forcing the found raid to always be root. Allow the old behavior with RAIDFRAME_FORCE_ROOT. XXX: cpu_rootconf() is called twice now, which prints the booted device message twice. Perhaps we can remember that cpu_rootconf has been called and avoid calling it twice to avoid that.
