Maybe related? From the release notes:
Known issues

As is to be expected at this stage of the release process, there are
several known bugs that users are likely to run into with Ubuntu 10.04
Beta 2. We have documented them here for your convenience along with any
known workarounds, so that you don't need to spend time reporting these
bugs again:

      Activating a RAID 1 array in degraded mode is reported to lead to
RAID disks being reported as in sync when they are not, resulting in
data loss. Since RAID 1 arrays will automatically be brought up in
degraded mode when a member disk is unavailable, users with production
software RAID 1 disks are advised not to upgrade to the 10.04 LTS Beta
until this bug is resolved. (557429)
