[PATCH] Btrfs: bail out if block group has different mixed flag

Currently we allow inconsistence about mixed flag (BTRFS_BLOCK_GROUP_METADATA | BTRFS_BLOCK_GROUP_DATA). We'd get ENOSPC if block group has mixed flag and btrfs doesn't. If that happens, we have one space_info with mixed flag and another space_info only with BTRFS_BLOCK_GROUP_METADATA, and

[PATCH] btrfs: do not decrease bytes_may_use when replaying extents

When replaying extents, there is no need to update bytes_may_use in btrfs_alloc_logged_file_extent(), otherwise it'll trigger a WARN_ON about bytes_may_use. Fixes: ("btrfs: update btrfs_space_info's bytes_may_use timely") Signed-off-by: Wang Xiaoguang ---

Re: Switch raid mode without rebalance?

I don't think its possible to change raid levels without using a balance. I'm not sure why you want to avoid a balance, its a background process that will auto resume if interrupted. You don't have to leave your machine on for weeks at a time and it shouldn't slow down an active application using

Switch raid mode without rebalance?

Hi, I recently created a new btrfs on two disks - one 6TB, one 2TB - for temporary backup purposes. It apparently defaulted to raid0 for data, and I didn't realize at the time that this would become a problem. Now the 2TB is almost full, and df tells me I only have about 200GB of free space.
