mdadm is a tool for creating, managing and monitoring
12
device arrays using the "md" driver in Linux, also
13
known as Software RAID arrays.
15
Release 2.1 fixes a few problems found after the release of 2.0.
16
If you are using raid10 or version-1 superblocks and upgrade is
20
- Fix assembling of raid10 array when devices are missing.
21
mdadm now correctly detects if a array is workable or not
22
depending on which devices are present, and so will correctly
23
handle "--assemble --force" if multiple devices have failed.
24
- Report raid10 layout in --examine output.
25
- Fix assembling of arrays that use the version-1 superblock and
26
have spares. Previously the spares would be ignored.
27
- Fix bug so that multiple drives can be re-added at once.
28
- Fix problem with hot-adding a bitmap to version-1-superblock
