As far as I know raid10 is ~ "a raid0 built on top of two raid1" ( http://en.wikipedia.org/wiki/Nested_RAID_levels#RAID_1.2B0 - raid10). So I think that by default in my case:
/dev/sda6 and /dev/sdb6 form the first "raid1" /dev/sdd6 and /dev/sdc6 form the second "raid1"
So is it so that if I fail/remove for example:
- /dev/sdb6 and /dev/sdc6 (different "raid1's") - the raid10 will be
usable/data will be ok?
- /dev/sda6 and /dev/sdb6 (the same "raid1") - the raid10 will be not
usable/data will be lost?
I'm not sure you can verify that.... I would play it safe, and only drop one drive at a time.
