Hi Everyone,

Use md's "single process" RAID10 with the standard near layout (which is 
apperently the same as RAID1+0 in industry), which 2 drives could fail 
without loosing the array?

This is what I have:

Number   Major   Minor   RaidDevice State
        0       8        5        0      active sync   /dev/sda5
        1       8       21        1      active sync   /dev/sdb5
        2       8       37        2      active sync   /dev/sdc5
        3       8       53        3      active sync   /dev/sdd5

Thanks
