its my 1st question here so please be kind.
I've got an monitoring server which is running on debian wheezy. It runs a RAID1 (2x 160GB) on a Adaptec Raid Controller (IBM ServeRAID 8k-l).
A few days ago on of the HDD failed. So i replaced it with another HDD with 250GB space (because there was no 160GB HD). Everthing looked fine, as the new HDD was replaced and the rebuilding have started. After it was finished, i got a massage from our Nagios raid_aac check:
there are some failed stripes on logical device 0 on controller 1!
In my opinion Raid1 doesn't work with Stripes so how could it be that i got this error message:

You guys got any hints, why i got this notification?
Do i have to replace the other 160GB HD as well with a 250GB HD because one of them got more space now, or do I really have to do a full backup and create a completely new array?
