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 dbf5d1f7a6 Nuke unused code. 2000-03-07 01:54:29 +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 0049933f0f Reorganize some comments. 2000-03-04 04:22:34 +00:00
oster 194aba4e41 Garbage collect the (already disabled) "random" queue type. 2000-03-04 03:27:13 +00:00
oster 612e2e8f92 Nuke an unneeded #define. 2000-03-04 03:22:17 +00:00
oster 88a8d06a0b Use the common disk allocation code, rather doing things the old way. 2000-03-03 03:47:17 +00:00
oster 142175b1a1 Minor formatting cleanup. 2000-03-03 03:10:03 +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)

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 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 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.

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.

- 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 bd19af5aad Nuke what's left of the DFSTRACE stuff. 1999-12-07 02:54:08 +00:00

disappeared a while back.
1999-12-07 02:13:28 +00:00

oster 3949e74f78 If we have a choice: do not trust the parity disk for read

1999-08-14 21:44:24 +00:00
oster 740b9848cc Decrease the number of outstanding IO's threashold slightly.

oster 31b98d3572 When reporting the status of a component during configuration,
provide more intuitive information about whether a component is clean
or not.
1999-08-10 22:56:20 +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 0b08c839eb Don't go ape if there is a problem verifying the parity. Note the condition
and inform the user (as opposed to panicing the system!).

oster 49efd10006 Oops. Make minor change that I forgot when adding the parity check ioctl. 1999-08-10 21:41:37 +00:00
oster a3aefdaee3 Add support for easily checking the parity status from userland.
Also: spl protect rf_RewriteParity().
1999-08-10 18:18:30 +00:00
oster a531d8c31e Trying to rebuild parity on a degraded set is bogus, so don't allow that.
Also, check sooner for a RAID 0 set, since rewriting parity makes no
sense there either.

oster e0c8203cb3 Nuke unused #define. 1999-08-03 22:07:39 +00:00
oster 5cef006d40 Need to splbio()/splx() protect some of the reconstruction stuff.
Without this, we have potentially bad interatctions with the pool
code.

oster ce7cb7114d rf_UnconfigureVnodes() needs to be called in the DO_RAID_FAIL macro. 1999-07-19 01:36:07 +00:00
oster 0c7600ca4e sectorsPerStripeUnit should be larger than 0. If it isn't, simply fail.
(Thanks to Thor Lancelot Simon for noting the problem).

oster 324c76b3d9 Once upon a time, long long ago, there was a "fix" added to the
RAIDframe driver to stop it from eating too much kernel memory when
writing data.  But that fix had a nasty side-affect of hurting write
performance (*much* more than I thought it would).  These changes nuke
that "fix", and instead put in a more reasonable mechanism for limiting
the number of simultaneous IO's which can be happening for each RAID device.
The result is a noticeable improvement in write throughput.  The End.

oster 86abd11d42 Remember to pass down the proc pointer when adding a hot spare.
(Thanks to Martin J. Laubach for helping track this one down.)
1999-06-13 20:36:17 +00:00
oster 8c39e1bf02 When adding a hot spare, remember to lock down the main raidPtr
structure before mucking with its contents.
1999-06-04 02:02:39 +00:00
oster 60769ea563 At config time, initialize a small amount of space for the disk queues
corresponding to the hot spares.  We'll need that space when a spare is
actually added.  Huge Thanks to Martin Laubach for helping track this down.
1999-06-04 01:51:00 +00:00
oster 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.

oster 9f560505d4 Allow re-writing parity on a RAID 0 to trivially succeed, and to set the
clean bit.  This is somewhat bogus as RAID 0 does not have any parity,
but is a slightly cleaner than other solutions, and makes the handling
of clean bits for RAID 0 consistent with the handling of clean bits at
other RAID levels.
