I've recently run aptitude update on a client machine running Linux Mint 13 Maya 64 on kernel 3.2.0-23. During update the update-grub ran into problems. It produces a lot of lines looking similar to the following:

ERROR: asr: seeking device "/dev/sdc" to 18446744073709551104
ERROR: ddf1: seeking device "/dev/sdc" to 18446744073709551104
ERROR: ddf1: seeking device "/dev/sdc" to 18446744073709420032
...
ERROR: asr: wrong # of devices in RAID set "asr_Datas" [1/2] on /dev/sdb

As far as I can tell this has something to do with the RAID drive, yet I don't know what this means or how to fix it if needed. grub does still find the correct boot options, but I am unsure that I should reboot right now to find out.
