From mboxrd@z Thu Jan 1 00:00:00 1970 From: NeilBrown Subject: [PATCH] md - 0 of 8 - Introduction Date: Fri, 28 May 2004 16:45:25 +1000 Sender: linux-raid-owner@vger.kernel.org Message-ID: <20040528163700.9426.patches@notabene> Return-path: To: Andrew Morton Cc: linux-raid@vger.kernel.org List-Id: linux-raid.ids 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. NeilBrown
