Report error when grow cannot be restarted.
...
Make sure that if --assemble find an array in the critical region
of a reshape, and cannot find the critical data to restart the
reshape, it gives an error message.

Fix error message when adding a device that is too small.
...
We were multiplying MD_RESERVED_SECTORS by 1024 instead of 512,
so lots of 'is it too small' checks were wrong.

005debfc11
Fix problem with add a device to a 1.x array created with older mdadm.
...
When adding new disk to an array, don't reserve so much bitmap
space that the disk cannot store the required data. (Needed when
1.x array was created with older mdadm).

Allow "--write-behind=" to be done in grow mode.
...
From: Ian Dall <ian@beware.dropbear.id.au>
I have a small patch to mdadm which allows the write-behind amount to be
set a array grow time (instead of currently only at grow or create
time). I have tested this fairly extensively on some arrays built out of
loop back devices, and once on a real live array.

Release 2.6.2
2007-05-21 14:25:53 +10:00
a77be58672
Make return code for "--detail --test" more reliable.
...
Missing devices as well as failed devices cause an error.
2007-05-21 14:25:50 +10:00
1f48664b8e
Add --auto-detect for in-kernel autodetect.
...
This is equivalent to raidautorun that some distros provide.
2007-05-21 14:25:44 +10:00
f752781f81
Fix --grow --add for linear arrays.
...
The new superblock needs to have a new disk.number. This is a bit of a hack...
Fix handling of negative bitmap offsets on 64bit hosts.
The bitmap offset is a signed 32bit number, so casting to (long)
isn't sufficient. We must cast to (int32_t).
Fix various problems with --grow --add for linear.
The code to add a drive to a live linear array had never
been tested properly and so was buggy. This tidies it up
and means that the new regression-test passes.
2007-05-21 14:25:37 +10:00
b80da66161
Support failing and removed of detached and faulty devices.
...
This if you unplug a device and udev removes the entry from /dev,
you can still remove the device.

Release 2.6.1
2007-02-22 15:04:59 +11:00

Fixed old documentation in --grow --help
2007-02-22 14:59:22 +11:00
48327135d6
Teach restripe to calculate Q syndrome for raid6.
...
This allows mdadm to correctly restart a raid6 grow that
crashed during the critcal phase.
2007-02-22 14:59:19 +11:00
ae491d1e2c
Fix a warning about an uninitialised variable.
...
The case that doesn't initialise it is impossible,
so just return with an error..
2007-02-22 14:59:16 +11:00
3e6944b2cc
Fix a bug that was causing incorrect warning from --monitor.
2007-02-22 14:59:13 +11:00

Release 2.6
2006-12-21 17:24:38 +11:00
8382f19bdc
Add new mode: --incremental
...
--incremental allows arrays to be assembled one device at a time.
This is expected to be used with udev.
2006-12-21 17:10:52 +11:00
3d3dd91e38
Support --uuid= with --create to choose your own UUID.
2006-12-14 17:33:10 +11:00
ab5303d695
Don't hold md device open for so long in --monitor mode
...
map_dev can be slow and interferes with trying to stop the array.
2006-12-14 17:32:53 +11:00
4a39c6f236
Check device is large enough before hot-add.
...
This improves quality of error message.
2006-12-14 17:32:49 +11:00
c5a6f9a61d
Change handling for "--assemble --force" when two drives disappeared at once.
...
If two drives in a raid5 disappear at the same time, then "-Af"
will add them both in rather than just one and forcing the array
to 'clean'. This is slightly safer in some cases.
2006-12-14 17:31:41 +11:00
bf4fb153a4
Fix and test --update=uuid
...
A number of odd bugs here, but now we have a regression test as well.
2006-12-14 17:31:29 +11:00
b90c0e9a12
--wait or -W will wait for resync activity to finish on the given devices.
2006-12-14 17:31:22 +11:00
e336254463
Change 'Device Size' to 'Used Dev Size'
...
because it only shows how much of each device is actually used, not
how big they are.
2006-12-14 17:31:19 +11:00
758d3a8e7d
Increase raid456 stripe cache size if needed to --grow the array.
...
The setting used unfortunately requires intimate knowledge of the
kernel, and it not reset when the reshape finishes.
2006-12-14 17:31:16 +11:00
583315d9c5
Give useful message if raid4/5/6 cannot be started because it is not clean and is also degraded.
2006-12-14 17:31:13 +11:00
7572344665
Default to --auto=yes
...
so the array devices with 'standard' names
get created automatically, as this is almost always what is wanted.
2006-12-14 17:31:10 +11:00
bee8ec56f4
Support --update=devicesize for cases where the underlying device can change size.
2006-12-14 17:31:03 +11:00
67a8c82d60
Make Assemble/Force work on raid6 with 2 missing devices.
...
Previously it onl worked when one missing device.
Also split the "force" update_super method into two and it
is really serving two functions.
2006-12-14 17:30:51 +11:00
434b77559e
--update=resync did exactly the wrong thing for version1 metadata.
2006-11-13 09:12:09 +11:00
b7a708af6f
Fixed UUID printing in "--detail --brief" for version1 metadata.
2006-11-09 16:28:27 +11:00
60e1bc1a33
Fixed problems that could cause infinitel loop with auto assemble.
...
If an auto-assembly attempt failes because the array cannot be
opened or because the array has already been created, then we
get into an infinite loop.

Document that the default metadata version can be overridden in config file.
...
From: Goswin Brederlow <brederlo@informatik.uni-tuebingen.de>
This is already mentioned in the config documentation, but not in the
place when the normal default is mentioned.

copies.

Don't trigger and error on -As if all arrays are already started.
...
From: Luca Berra <bluca@comedia.it>
Put another way, if we find any active arrays, then assume things are
going as planned.

Don't fail md_open if array already active.
...
From: Luca Berra <bluca@comedia.it>
There is no need and it causes occasional problems.

Mdassemble improvements
...
From: Luca Berra <bluca@comedia.it>
- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
This is useful if they are started read-only as is best at boot-time.
2006-10-16 15:26:53 +10:00

Reduce max bitmap size when bitmap is in a file.
...
To ensure kernel never needs to allocate more than 1 page contiguously.

Don't #include blkpg.h

Just include the content directly. It is safer.

Remove partitions from components of an md array
...
They do nothing but cause confusion.
2006-10-13 09:02:35 +10:00
6ba83b5f5e
Allow a number after --auto=yes
...
So if the device name is /dev/md/d0, then the number of
partitions is as given. This is useful in 'CREATE' in
mdadm.conf

it require --run. This fixes that.
