oster e44151e8d6 Fix up some autoconfigure messages. In particular, don't try printing 
the value of an uninitialized variable.  Noted by Luke Mewburn.
 2000-03-22 01:41:41 +00:00
oster 7f288b4e0d Just return "100% done" when asked about reconstruction progress on 
a RAID0 set.
 2000-03-20 22:59:26 +00:00
oster 7c57ac56d7 Cleanup a couple of function declarations. No functional changes. 2000-03-07 03:09:47 +00:00
oster 51ffb0924c Create a new rf_close_component() to handle vnode operations for closing 
components.  Teach rf_UnconfigureVnodes() how to use it, and tell
the copyback and reconstruction code about it too.
 2000-03-07 02:59:50 +00:00
oster 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 .
 2000-03-07 02:28:05 +00:00
oster 33a55d022b rf_ protect the component label print routine, and make it more easily 
available to the rest of RAIDframe.
 2000-03-07 02:12:13 +00:00
oster 1231bd6d14 Umm... don't allow attempts to configure the same RAID device multiple times. 
The check was there, but the return() was missing :(
 2000-03-04 06:03:21 +00:00
oster 87f46374bb Minor cleanup. No functional changes. 2000-03-03 01:46:36 +00:00
oster 8c46e74418 Nuke some debugging output that got left in by mistake. 2000-02-27 02:35:33 +00:00
oster 82419f5ae9 Only mark the components as CLEAN if it's the last thing we're doing. 
Marking them CLEAN earlier is (currently) asking for trouble.
(XXX This could have been done more elegantly.)
 2000-02-27 01:50:22 +00:00
oster d9c47013b2 Defopt 'RAID_AUTOCONFIG'. Adding 'options RAID_AUTOCONFIG' turns on 
the component auto-detection and auto-configuration of RAID sets.
Also, add "#options RAID_AUTOCONFIG" to the GENERIC config files.
 2000-02-26 17:35:33 +00:00
oster caa3932441 Minor cleanups. Remove extra debugging printouts. 2000-02-25 20:11:00 +00:00
oster 21243f6205 - ignore the mod_counter when checking to see if a component fits with the 
rest of an autoconfig set.
- minor cleanups
 2000-02-25 19:56:56 +00:00
oster a4f7f062fd - cleanup raidinit() 
- cleanup rf_mountroot_hooks()
- various other cleanups.
 2000-02-25 02:42:30 +00:00
oster 5716b5d6d1 Be *slightly* more consistent about the use of num and numraid in raidattach(). 2000-02-25 02:21:12 +00:00
oster 99f070bab8 - mod_counter needs to get incremented more often. 
- use raid_init_component_labels instead of hand-rolling a component_label.
(missed doing this for the rf_used_spare case when updating component labels).
- fix serial number initialization in raid_init_component_labels
 2000-02-24 01:23:05 +00:00
oster d91ecfbcfd Be more aggressive about updating component labels in the event 
of a real component failure (or a simulated failure):
- add 'numNewFailures' to keep track of the number of disk failures
since mod_counter was last updated for each component label.
- make sure we call rf_update_component_labels() upon any component failure,
real or simulated.
 2000-02-23 03:44:02 +00:00
oster e7f3dc2ec9 blockSize for the component label is already set correctly here. 2000-02-23 02:11:05 +00:00
oster 0c43bf18f0 - cleanup of more component label code 
- make current default label values available everywhere
- make sure numBlocks and blockSize in component labels get initialized
for all component labels
- check for component size to be smaller than or equal to the partition size
when autoconfiguring
 2000-02-23 02:04:21 +00:00
oster 214822e08c Note the fact that the first arg of raidinit() may be bogus in 
the autoconfig case (the value of the first arg never gets used, but...).
 2000-02-22 23:13:15 +00:00
oster e8ff7f6155 Bounds-check the 'last unit' a little more closely. 2000-02-22 16:07:02 +00:00
oster bd2230fd09 - implement additional component checking before autoconfiguration 
- make component label setting work again(!!!!)
 2000-02-22 03:38:42 +00:00
oster afccbaa6d7 Umm.. let's set 'numraid' to something useful before we try to use it. 2000-02-21 23:33:45 +00:00
oster 7deba340d7 Some of these function names are bad enough that no one else would probably 
pick them, but preface them with rf_ anyway.
 2000-02-16 01:10:44 +00:00
oster 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)
 2000-02-13 04:53:57 +00:00
thorpej dc59bc1db3 Update for sys/buf.h/disksort_*() changes. 2000-01-21 23:39:55 +00:00
oster 7ce0db89f9 Nuke more debugging stuff and cleanup a tad. 2000-01-09 03:39:13 +00:00
oster 23c4c71c8f By popular demand (Hi Thor!) make the cylinder size in a default 
disklabel be the size of the (data part) of the stripe.
 2000-01-09 02:56:13 +00:00
oster c8730b35e6 - move a bunch of function prototypes to rf_kintf.h 
- general cleanup of a number of prototypes that were scattered around.
 2000-01-09 01:29:27 +00:00
oster db96c5344b Nuke some (now) incorrect comments. More minor cleanup. 2000-01-08 02:04:06 +00:00
oster ef979643a7 Replace raidPtrs[unit] with just raidPtr, and assign the former to the 
later early on in raidioctl().  Code is easier to read now too.
 2000-01-08 01:52:42 +00:00
oster b9a1fe405c Minor tillage on the raidioctl() stuff. More cleanup to follow. 
No functional changes.
 2000-01-08 01:37:37 +00:00
oster 91273673e7 In RAIDFRAME_CONFIGURE, don't set values in raidPtrs[unit] unless 
the configuration was successful.  Noted by Peter Galbavy of OpenBSD.
 2000-01-07 13:57:20 +00:00
oster 51380e0e8c - bail if we can't allocate memory for raid_softc's. Set 'numraid' as 
appropriate for that condition.
- nuke some debugging stuff that we hope we'll never need again
- minor cleanups
 2000-01-06 02:06:41 +00:00
oster d4dfa2a664 Make sure we really get something back from RF_Malloc before we use it. 2000-01-05 04:15:30 +00:00
oster 77ab4d1598 - update RF_CREATE_THREAD to handle a 'process name' argument. 
- fire up a new thread for parity re-writes, copybacks, and reconstructs.
  The ioctl's which trigger these actions now return immediately.
- add progress accounting for the above actions.
- minor rototillage of rf_netbsdkintf.c to deal with all of the above.
 2000-01-05 02:57:28 +00:00
oster 28c2380f21 Nuke a bunch of debugging cruft. No functional changes. 1999-12-15 02:02:16 +00:00
oster fe0726b921 Whoops! Neglected to initialize the buffer queues for anything other 
than raid0.  Fix that...
 1999-12-14 15:27:00 +00:00
oster e8a639b1df Rototill the IO throttle code. Rename rf_DoAccessKernel() to raidstart() 
and cleanup arguments.  While we're here, cleanup raidstrategy(), and nuke
a bunch of unused debugging stuff.

RAIDframe + softdeps now play very nicely together.
 1999-12-12 20:51:41 +00:00
oster a038f90588 Kernel memory is not to be wasted. If we're bailing out because of an error, 
give any allocated memory back to the kernel so someone else can use it.
 1999-12-03 03:06:44 +00:00
oster 3888a71ad1 Move LIST_INIT() to a more appropriate place. 1999-12-03 02:43:22 +00:00
oster 5fd68b5d02 We must initialize bp->b_dep in InitBP(). 1999-11-18 13:28:06 +00:00
oster e589155692 Remove some minor stuff that wasn't right, and wasn't even really used. 1999-11-17 01:16:37 +00:00
oster 07cc4855f1 Minor cleanup. No functional changes. 1999-08-14 23:34:18 +00:00
oster 740b9848cc Decrease the number of outstanding IO's threashold slightly. 
The previous value may have been too high in some instances.
 1999-08-14 03:47:07 +00:00
oster 6409e641a6 Remove a 'struct proc *'-passing abomination that's been bugging me 
for quite some time.
 1999-08-14 03:10:03 +00:00
oster 4a058e82c5 Correct and/or improve detection of bogus row/column values 
passed in via ioctls.
 1999-08-14 02:41:36 +00:00
oster 1aa6ce1041 Garbage collect rpcc(). 1999-08-13 03:27:46 +00:00
oster 620eda50c7 Don't allow reconstructs, copybacks, or forced failures of components if 
using a RAID 0, since RAID 0 can't handle those sorts of things.
 1999-08-10 22:46:59 +00:00
oster 49efd10006 Oops. Make minor change that I forgot when adding the parity check ioctl. 1999-08-10 21:41:37 +00:00
