Subject: ANNOUCE: mdctl 0.6 available
Date: Thu, 7 Mar 2002 10:20:59 +1100 (EST)
From: Neil Brown <ne...@cs...>
To: lin...@vg...
I would like to announce the availability of mdctl-0.6 from
http://www.cse.unsw.edu.au/~neilb/source/mdctl/
Note:
it is expected that the name will change when 1.0 comes out,
probably to mdadmin (it is easier to pronounce)
Changes:
There is now a ChangeLog file. The relevant section is below.
Highlights are:
--build actually works!
--examine --scan
creates some ARRAY lines suitable for mdctl.conf
Manpage substantially improved
Please read the manpage and tell me where further improvements can
be made.

Changes Prior to 0.6 release
- Remove the limit on the number of device names that can be
given on the command line.
- Fix bug in --assemble --force where it would only update a
single superblock.
- Fix bogus printing of big numbers not being block devices
when given names of devices that don't exist.
- When --assemble --force, consider superblocks with an event
count that is 1 behind as out-of-date. Normally they are
considered up-to-date (as the kernel assumes this too).
- When marking drives as not-failed in the superblock,
we also mark them as ACTIVE and SYNC.
- Don't start arrays for which not all drives are available unless:
--scan which implies that all drives were found automatically
--run which means the user knows what they want
--force which means that we are fixing something broken
- Make sure all device numbers passed as 3rd arg of ioctl
are passed as unsigned lock, so that it works on SPARC
- If HOT_ADD_DISK failes for -a, then only try ADD_NEW_DISK
if we cannot read from the array, i.e. if the array is
not started yet.
- man page update
- Taught Examine to handle --scan. It examines all devices listed
on DEVICE lines in the config file.
- Added --brief (-b) flag for Examine and Detail to print out
and mdctl.conf compatible description with uuid=, level=,
disks= and - for Examine - devices=
--examine --brief collects all devices the make the one array and
list them as one entry.
- Added level= and disks= options to ARRAY lines in config files
so --brief output could be used as-is.
- Make parity style ({left,right}-{,a}symmetric) consistantly use -,
never _.
- Add "Array Size" to --detail output
- Change "Size" to "Device Size" and exclude from Detail of arrays
that do not have a consistent device size.
- Add Human readable MiB or GiB value on size lines of Detail and Examine
- --assemble --scan doesn't complain about active drives
- require number of spares given in -x to be listed.
- Made --build actually work.
-
