The idea is that you get +udev to run "mdadm -Iq devicename" on each new block device that it +finds. Anything that is part of an array gets included in an array as +appropriate. +Two special notes: + 1/ This is very new code and is probably buggy. It passes a few basic + tests, and helped me find some kernel bugs, but it is still fresh + and should not be considered 'stable'. Please test and provide + feedback. + 2/ There is a bug in the linux kernel that makes incremental assembly + not possible in general (you cannot safely remove a drive from an array + that has not yet been started. This is needed if an old device was + detected first). If mdadm detects a kernel which might have the + bug, it rejects --incremental requests. + The bug will hopefully be fixed in 2.6.20 and this mdadm release + contains patches for 2.6.18, 2.6.18.6 and 2.6.19. Apply the + appropriate patch to test --incremental. + +Changelog Entries: + - Fixed UUID printing in "--detail --brief" for version1 metadata. + - --update=resync did exactly the wrong thing for version1 metadata. + It caused a resync to not happen, rather than to happen. + - Allow --assemble --force to mark a raid6 clean when it has two + missing devices (which is needed else if won't assemble. + Without this fix it would only assemble if one or zero + missing devices. + - Support --update=devicesize for cases where the underlying device + can change size. + - Default to --auto=yes so the array devices with 'standard' names + get created automatically, as this is almost always what is wanted. + - Give useful message if raid4/5/6 cannot be started because it is + not clean and is also degraded. + - 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. + - Change 'Device Size' to 'Used Dev Size' because it only shows how + much of each device is actually used, not how big they are. + - --wait or -W will wait for resync activity to finish on the given + devices. + - Fix some problems with --update=uuid and add a test. + - 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. + - Check device is large enough before hot-add: this improves quality + of error message. + - 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. + - Support --uuid= with --create to choose your own UUID. + - New major more "--incremental" for incremental assemble of arrays, + intended for use with udev. + +Development of mdadm is sponsored by + SUSE Labs, Novell Inc. + +NeilBrown 21st December 2006 +Blessed Christmas to all. @@ -1,4 +1,4 @@ -Changes Prior to this release +Changes Prior to 2.6 release - Fixed UUID printing in "--detail --brief" for version1 metadata. - --update=resync did exactly the wrong thing for version1 metadata.
