buhrow 3dd51f1b7e Document the need for zeroing out the first 64 blocks of a replacement
component in a failed RAID set in order to avoid potentially configuring
RAId 1 sets with erroneous values taken from random extent data in the
replacement component partitions.

enami ec02ea412c Define accessors for number of blocks and partition size in the
component label and use them where appropriate.  Disscussed on tech-kern.

pooka a804f47907 Exterminate a bug I created in 2009. 2011-02-09 11:22:49 +00:00
pooka db818c53ab Use RUMPPRG.
ok Greg Oster

pooka f1d4214202 Update RUMP_ACTION to use rumpclient.
The server must of course have some disks configured.  Let's say
we have this simple server with disks as a few sparse host files:

main()
{
        rump_init();
        rump_pub_etfs_register("/disk1", "./disk1.img", RUMP_ETFS_BLK);
        rump_pub_etfs_register("/disk2", "./disk2.img", RUMP_ETFS_BLK);
        rump_pub_etfs_register("/disk3", "./disk3.img", RUMP_ETFS_BLK);
        rump_pub_etfs_register("/disk4", "./disk4.img", RUMP_ETFS_BLK);
        pause();
}

And we run the server:

mainbus0 (root)
Kernelized RAIDframe activated
/disk1: hostpath ./disk1.img (97 GB)
/disk2: hostpath ./disk2.img (97 GB)
/disk3: hostpath ./disk3.img (97 GB)
/disk4: hostpath ./disk4.img (97 GB)

We can then configure the raid against the server:

> ./raidctl -c theraid.conf raid0

And lo, we have evidence of a level1 raid in the server dmesg:

raid0: RAID Level 1
raid0: Components: /disk1 /disk2 /disk3 /disk4
raid0: Total Sectors: 409599744 (199999 MB)

yea, i initialized it already in a previous run:

> ./raidctl -S raid0
Reconstruction is 100% complete.
Parity Re-write is 100% complete.
Copyback is 100% complete.

jld 8ccd0f67a6 Exclude parity map regions that don't actually exist from the dirty region count
in `raidctl -m`.  Makes for less confusing output during `raidctl -i`.

wiz 4421a69224 Consistently use "START disks" in examples. Bump date. 2010-01-27 08:56:08 +00:00
jld 9bd6e2661a Slight change to the wording of the parity map info: the parity is
"marked clean" after however much inactivity; it is *actually* clean
as soon as the component disks all do their thing (on the order of ms,
usually), just the same as before.

The bikeshed is now less of a taupe and more of an ecru.

jld 9e2ba7b416 Bump date; also fix typo pointed out by snj@. 2009-11-17 19:09:38 +00:00
jld f1a1ad338d Finally commit the RAIDframe parity map Summer Of Code project.
Drastically reduces the amount of time spent rewriting parity after an
unclean shutdown by keeping better track of which regions might have had
outstanding writes.  Enabled by default; can be disabled on a per-set
basis, or tuned, with the new raidctl(8) commands.

Discussed on tech-kern@ to a general air of approval; exhortations to
commit from mrg@, christos@, and others.

Thanks to Google for their sponsorship, oster@ for mentoring the
project, assorted developers for trying very hard to break it, and
probably more I'm forgetting.

tron 0c5d87d569 Use correct format to print the "numBlocks" element in a RAIDframe
component label. raidctl(8) should now print the correct number of
blocks for RAID sets larger than 1TB.

Patch supplied by Bernhard Moellemann in PR bin/40479.

thanks to) Christoph (bad@).

oster 42abd8f7a0 Cleanup a bit by nuking RF_Malloc macro, and add in some error
checking for the case where we can't allocate memory.  (Not like
anyone uses this part of the code anyway.)

oster fa730392bc Strip off trailing \n's and spaces from configuration file lines.
Makes RAIDframe more forgiving if you accidentally add a space after
things like device names.  Fixed at long last after a reminder over
the weekend.

oster 2b7fd0220d How about we use the 'len' parameter to rf_get_next_nonblank_line()
instead of assuming all buffers are 256 bytes.
