5 | Subject: [PATCH 2/5] Check for RAID10 in set_avail_alloc_bits | ||
6 | |||
7 | When raid is setup with mkfs, it is supposed to cow the initial filesystem | ||
8 | it creates up to the desired raid level. RAID10 was not in the list | ||
9 | of RAID levels it checked for, so the initial FS created for RAID10 | ||
10 | actually only lived on the first disk. | ||
11 | |||
12 | This works well enough because all the roots get quickly cowed during the | ||
13 | first mount. The exception is the data relocation tree, which only gets | ||
14 | cowed when we do a balance. | ||
