RAID10 was not in the list +of RAID levels it checked for, so the initial FS created for RAID10 +actually only lived on the first disk. + +This works well enough because all the roots get quickly cowed during the +first mount. The exception is the data relocation tree, which only gets +cowed when we do a balance. + +Signed-off-by: Chris Mason <chris.mason@oracle.com> +--- + extent-tree.c | 1 + + 1 files changed, 1 insertions(+), 0 deletions(-) + +diff --git a/extent-tree.c b/extent-tree.c +index b2f9bb2..108933f 100644 +--- a/extent-tree.c ++++ b/extent-tree.c +@@ -1775,6 +1775,7 @@ static void set_avail_alloc_bits(struct btrfs_fs_info *fs_info, u64 flags) + { + u64 extra_flags = flags & (BTRFS_BLOCK_GROUP_RAID0 | + BTRFS_BLOCK_GROUP_RAID1 | ++ BTRFS_BLOCK_GROUP_RAID10 | + BTRFS_BLOCK_GROUP_DUP); + if (extra_flags) { + if (flags & BTRFS_BLOCK_GROUP_DATA) +-- +1.7.2.3 + |
