oster 142175b1a1 Minor formatting cleanup. 2000-03-03 03:10:03 +00:00
oster 7b1139520e More minor cleanup. 2000-03-03 02:04:48 +00:00
oster 87f46374bb Minor cleanup. No functional changes. 2000-03-03 01:46:36 +00:00
oster 8cde772948 Oops.. Need to note the parity status when we unconfigure. 
Noted by Aaron J. Grier. (Thanks!)
 2000-02-29 16:54:29 +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 503220a18f - ignore components whose mod_counter values are too low. 
- noting the mod_counter for autoconfigured sets would be a win too.
 2000-02-25 19:56:32 +00:00
oster 8d63540a8c When we close autoconfigured components, we need to note that they 
are no longer in 'autoconfigured' status.
 2000-02-25 17:14:18 +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 e4e4483cb7 Fix a (slightly) bogus status message. 2000-02-25 02:06:34 +00:00
oster bdd659fc7f Deal with unconfiguring components in the autoconfigure case. 2000-02-24 23:39:21 +00:00
oster aea97a5a17 Oops... Missed commmitting this last night. Thanks to Matthias Scheler 
for letting me know.
(Add the DiskQueueSW pointer)
 2000-02-24 17:12:10 +00:00
oster e644abfe94 Make sure we close auto-configured components appropriately when 
attempting a rebuild-in-place.
 2000-02-24 04:39:41 +00:00
oster c5961cfba3 Garbage collect some unused stuff. Include rf_kintf.h for a 
function prototype.
 2000-02-24 03:52:15 +00:00
oster 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.
 2000-02-24 03:48:41 +00:00
oster 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).
 2000-02-24 02:55:05 +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 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.
 2000-02-24 01:22:32 +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 6aaac32240 Do a better job of (re)initializing the component labels after 
a reconstruct or a copyback.
 2000-02-23 02:03:03 +00:00
oster d84e4ed019 Make a note of autoconfigured components. 2000-02-23 02:01:55 +00:00
oster e0ab2f3d0f Correct a comment. 2000-02-23 00:37:11 +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 fb56415023 Add a few comments, and an indicator of whether or not an autoconfig set 
is 'rootable'.
 2000-02-22 03:39:47 +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
oster edc931efea Make this compile without warnings on alphas. 
(Problem noted by Aaron J. Grier)
 2000-02-12 16:06:27 +00:00
thorpej dc59bc1db3 Update for sys/buf.h/disksort_*() changes. 2000-01-21 23:39:55 +00:00
oster 138d8fef04 Fix typo + cleanup a bit. 2000-01-15 01:57:57 +00:00
oster ef035f5a7b Make more 80-column friendly. No functionality changes. 2000-01-14 04:03:52 +00:00
oster 11e019370e "fix" a serious problem with RF_AccTraceEntry_t tracerec stuff. 
XXX the "fix" is incorrect, but that makes it consistent with
some of the other code here.  A this point you should *not* be
thinking about using this code. (At all.) (And I mean it.)
 2000-01-14 01:00:26 +00:00
oster ee867c7fdf Add some debugging printfs. 2000-01-14 00:57:57 +00:00
oster ec84f30ddd If we can't malloc a RF_ShutdownList then we should return ENOMEM right away. 
Waiting for more kernel memory to come along can cause more problems than
we're willing to deal with right now.
 2000-01-13 23:41:18 +00:00
oster 2c4bbb1b26 At (closer to) 80-columns, this may actually be readable code. 2000-01-09 04:35:13 +00:00
oster f2a8aaee02 Garbage collect unused code. 2000-01-09 03:44:33 +00:00
oster 7ce0db89f9 Nuke more debugging stuff and cleanup a tad. 2000-01-09 03:39:13 +00:00
oster b0caf96f87 It's got to help to check the *right* value if you care what 
RF_Malloc() is returning.
 2000-01-09 03:28:11 +00:00
oster fbd3b6b396 Another one bites the dust. 2000-01-09 03:17:12 +00:00
oster 87ec1ad21b Nuke dependency on rf_diskthreads.h 2000-01-09 03:15:59 +00:00
oster 4a54cff7d7 Nuke dependencies on rf_cpuutils.h. 2000-01-09 03:14:32 +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 754613774a rf_cpuutil.c isn't useful for the kernel driver. 
*poof* *poof*
 2000-01-09 02:23:21 +00:00
oster c8723703d2 Not sure why this file was still around since it's really not required. 
*poof*
 2000-01-09 02:05:12 +00:00
oster 6e92bd4525 Nuke unused debugging stuff. Clean up a whole bunch of comments. 2000-01-09 01:45:58 +00:00
oster a5dcdf8572 Nuke a couple of obsolete comments. 2000-01-09 01:34:29 +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 08817bcd50 Nuke #if 0'ed code. 2000-01-09 01:12:05 +00:00
oster cdb6add0f7 Nuke desc->tid. 2000-01-09 00:00:18 +00:00
oster 37c75452f4 Time's up. This file is no longer needed. "toodles." *punt* 2000-01-08 23:54:26 +00:00
oster 418d4b8471 - more cleanup of rf_get_threadid() and debugging printfs 2000-01-08 23:45:05 +00:00
oster 524894d6f2 Make raidPtr a 'RF_Raid_t *' like it's supposed to be. 2000-01-08 23:02:16 +00:00
oster 04719e3adc - nuke calls to rf_get_threadid() and associated #include 
- change a bunch of debugging printfs from
  "[%d] ...", tid   (where tid is the "thread id")
to
  "raid%d: ...", raidPtr->raidid
- other minor rototillage
 2000-01-08 22:57:30 +00:00
oster 23864e9422 Bail if rf_numParityRegions is not > 0. Cleanup a comment. 2000-01-08 05:13:26 +00:00
oster 0d2f49b054 Nuke stale comment. 2000-01-08 03:49:37 +00:00
oster e7fe279817 Minor cleanup. 2000-01-08 03:34:31 +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 a4ea38dbe8 Nuke an unneeded #ifdef (__NetBSD__) 2000-01-08 01:18:36 +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 bf2d4a40db rf_GetNextReconEvent() is already prototyped in rf_revent.h. 
minor cleanup
 2000-01-07 03:56:14 +00:00
oster 12dacda256 nuke one call to rf_get_threadid() and cleanup rf_State_Cleanup a bit. 2000-01-07 03:47:15 +00:00
oster bf081bf6eb Nuke: #include "rf_threadid.h" and call to rf_get_threadid(). 2000-01-07 03:43:39 +00:00
oster 48301a8dae Nuke: #include "rf_threadid.h". 2000-01-07 03:40:56 +00:00
oster e5ce17d0eb Nuke RF_DECLARE_GLOBAL_THREADID, rf_setup_threadid(), rf_shutdown_threadid(), 
and rf_assign_threadid().  rf_threadid.h, your days are numbered.
 2000-01-07 03:25:34 +00:00
oster 86f362fb97 Nuke unused #define. 2000-01-07 03:04:41 +00:00
oster 5f144eaa4b Shorten IO_BUF_ERR macro by one (unused) arg. 2000-01-07 03:03:44 +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 c8753ea619 Rework how we do the 'wakeup' when an IO completes. 1999-12-12 20:52:37 +00:00
oster 706e3c13c0 Rename rf_DoAccessKernel() to raidstart() and cleanup arguments. 1999-12-12 20:52:16 +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 a0d72cb555 Trust only the data disk if the mirror is not known to be up-to-date. 
(this should have been committed with a previous fix for the same
problem in another function in this file :( )
 1999-12-09 02:26:09 +00:00
oster bd19af5aad Nuke what's left of the DFSTRACE stuff. 1999-12-07 02:54:08 +00:00
oster e65f9b7c87 More cleanup. DKUSAGE (what little was left of it) goes bye-bye. 1999-12-07 02:40:27 +00:00
oster a38b721e5f Nuke the last few bits of RF_DEBUG_ATOMIC that should have 
disappeared a while back.
 1999-12-07 02:13:28 +00:00
oster bed152a4e7 We don't support RF_DAG_TEST_ACCESS. 1999-12-03 03:35:30 +00:00
oster 128e2e90c5 Nuke some duplicate code. 1999-12-03 03:18:45 +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 3949e74f78 If we have a choice: do not trust the parity disk for read 
balancing in a RAID 1 set if we know that the parity might not
be up-to-date.  Thanks to Thor for bringing this to my attention.
 1999-11-09 03:07:20 +00:00
oster fe5b29ca42 Nuke unused prototype. 1999-09-08 02:01:55 +00:00
oster 83abb87d9a Garbage collect more unused stuff. 1999-09-05 03:05:55 +00:00
oster 9c01870db1 Remove more unused stuff. 1999-09-05 02:54:09 +00:00
oster cfbdda8843 Garbage collect some more stuff. 1999-09-05 02:24:58 +00:00
oster 6158faa69d Cleanup a bit more. 1999-09-05 01:58:11 +00:00
