7a8eea351b Fix a couple of warnings about uninitialized variables. Thanks go to 
Frank van der Linden for pointing these out.

3fa62c4642 Make sure we are passing a locked vp to VOP_CLOSE. 2000-09-08 01:36:35 +00:00

66e6338ac9 Use 'componentN' rather than leaving blanks for non-existant disks 
in the 'raidctl -s' output.

c11100526b Don't let the autodetection code get tripped up by negative mod-counters. 2000-05-29 02:57:34 +00:00

39a667120f In the event that an up-to-date component cannot be located for a specific 
position, see if there is a failed component still hanging around that
we can use instead (but still mark it as failed).  This leads to more
reasonable behaviour (and fewer surprises!) when autoconfiguring and
failed (or previously failed) components are still on the system.

f329fb84ad We need to be slightly more clever during auto-configuration, to make 
sure that we a) don't ignore components with correct mod-counters, and
b) do ignore components with bogus mod-counters.

2ee63332b3 Add bits for eventual support of deleteing components and moving 
hot-spares into the main set.

d9da26f998 Nuke a function prototype that shouldn't be here. 2000-03-25 16:24:57 +00:00

ddebc1cad0 Move rf_UnconfigureVnodes to rf_netbsdkintf.c where it will be more at home. 
Add prototype to rf_kintf.h, and nuke old prototypes from rf_disks.c and
rf_driver.c .

503220a18f - ignore components whose mod_counter values are too low. 
- noting the mod_counter for autoconfigured sets would be a win too.

851a2cdcd8 - record the pointer to the DiskQueueSW so we can use that when 
we hot-add a spare.
- use the above info when adding a spare.

9e81bc058e Now that we have the information available, use the general maxOutstanding 
value for the RAID set, rather than looking at Queue[0][0] (which may not
exist).

fb13ce76fc - make sure we note the parity status in the autoconfig case. 
- also, make sure we grab the serial number from the component labels
when we autoconfig.

445591e874 Get recent changes into the tree: 
- make component_label variables more consistent (==> clabel)
- re-work incorrect component configuration code
- re-work disk configuration code
- cleanup initial configuration of raidPtr info
- add auto-detection of components and RAID sets (Disabled, for now)
- allow / on RAID sets (Disabled, for now)
- rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype
in rf_diskqueue.h
- protect some headers with #if _KERNEL  (XXX this needs to be fixed properly)
  and cleanup header formatting.
- expand the component labels (yes, they should be backward/forward compatible)
- other bits and pieces (some function names are still bogus, and will get
changed soon)

c8730b35e6 - move a bunch of function prototypes to rf_kintf.h 
- general cleanup of a number of prototypes that were scattered around.

db2eaf18cf rf_sys.h does not need to be #included in any of these files, and, actually, 
is no longer needed at all.

31b98d3572 When reporting the status of a component during configuration, 
provide more intuitive information about whether a component is clean
or not.

structure before mucking with its contents.

3af0ce9e19 Don't count two problems with a single component as two 
component failures!  Also: remember to configure the disk queues for
the spares -- failure to do that is Bad(tm).
Huge Thanks to Martin Laubach for helping track this down.

65be57243f Minor cleanups and code rearranging. Now knows a little about component 
labels and how to deal with hot-adding spare components.  Still work in
progress -- component labels and hot-adding are not enabled (yet).

0014588545 Phase 2 of the RAIDframe cleanup. The source is now closer to KNF 
and is much easier to read.  No functionality changes.

1eecf8e491 RAIDframe cleanup, phase 1. Nuke simulator support, user-land driver, 
out-dated comments, and other unneeded stuff.  This helps prepare
for cleaning up the rest of the code, and adding new functionality.

No functional changes to the kernel code in this commit.

38a3987b69 RAIDframe, version 1.1, from the Parallel Data Laboratory at 
Carnegie Mellon University.  Full RAID implementation, including
levels 0, 1, 4, 5, 6, parity logging, and a few other goodies.
Ported to NetBSD by Greg Oster.
