14de6c2418 Cleanup shutdown code - garbage collect (now) unused shutdownhooks() stuff. 1999-03-27 01:26:37 +00:00

efe288e520 Correct a component label problem where a RAID 1 set with a 
failed component would not configure properly in certain situations.

2ec2c2045f Cleanup rf_RewriteParity() and rf_VerifyParity(). Nuke unused stuff, 
and make more readable.

414b788837 Disallow interrupting parity re-writes or copybacks by removing PCATCH 
from the tsleep()'s (they probably shouldn't have been there in the
first place!).  Making parity re-writing and copybacks interruptable
will require re-designing how a few things are done (e.g. how memory
is freed for structures shipped off to routines that run asynchronously
relative to the calling routine).  Fix a few other tsleep's while we're at it.

cd0a696176 Cleanup raidattach: move rf_boot's functionality to raidattach, and 
nuke rf_boot().  Cleanup raidopen().

29daf0c77d rf_update_component_labels() now lives here. Re-work clean-bit 
support a little: clean-bits now also get frobbed on partition
opening/closing, rather than just at device configuration and device
unconfiguration.  Schedule shutdownhooks() stuff for nukage at a later
date, since it isn't really necessary any more.

ee9187f136 After a vn_close(), set the vnode * to NULL so we don't try closing it 
again later.

a76f56098c Do the VOP_UNLOCK() on an initialized vp, rather than random garbage. 1999-02-27 01:48:13 +00:00

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).

be9eca67c8 Cleanup/remove unused cruft. First kick at component labels and clean bits. 
Still work in progress.  New code is there, but 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.

58f7de552d Nuke more bits of RAIDframe "demo" code. We're not "demoing" here, 
we're doing the Real Thing!

d94a2c5b2a These files are not used in the kernel driver. We don't need them any more. 1999-01-26 03:07:10 +00:00

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.

edd259d12e Make it so raidframe will only perform synchronous writes, and async 
reads.  This avoids a problem where many writes will cause the driver
to allocate way too much memory.

This needs to change to a queueing system later, which will provide a
way to limit the memory consumed by the driver.

Without these changes, raidframe would use 24M or more on my machine when
the buffer cache dumped all its dirty blocks.  Now it uses around 200k
or so.

4128f9df1e Duh... check that malloc() hasn't returned a NULL *before* we zero the buffer, 
not after. Pointed out by Michael Graff.

1b04131eff Try a bit harder to detect the physical failure of a component, and to 
mark that component as dead.  Physical failures are handled much better now.

3f3d8e85e6 If a configuration fails due to a non-existant spare, remember to release 
any previously allocated components before bailing.  Credit to Manuel Bouyer
for noticing this.

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.
