Subject: [PATCH] md - 0 of 8 - Introduction
Date: Fri, 28 May 2004 16:45:25 +1000 [thread overview]
Message-ID: <20040528163700.9426.patches@notabene> (raw)
Following are 8 patches for md in 2.6.7-rc1-mm1
The first 6 a ready to go to Linus.
The last two are sufficiently new that maybe they should wait a while,
but I don't have any serious concerns about them and have tested them quite a bit.
1 - tidy up some multipath code
2 - fix a bug which stopped failed drives from being removable
in some cases.
3 - rationalise use of ->hot_remove_disk method.
4 - double check that size in a multiple of chunksize of raid5/6
(needed for a subsequent patch)
5 - Fix problem with hot-adding to array with non-persistant superblocks.
6 - Get raid1 to cope sensible with a device failure during rebuild.
and the new functionality.
7 - support resizing of devices in raid1/4/5/6. If the devices are replaced
with larger ones, the array can grow while online to use the extra space
8 - support adding and removing active drives for raid1. i.e change a raid1
array that used 2 drives so that it uses 3 drives, or vice-versa.
I will release a new mdadm in a few days that provide "--grow" for using
this functionality.
