btrfs: add support for 4-copy replication (raid1c4)

2019-11-18T16:51:49Z

Add new block group profile to store 4 copies in a simliar way that current RAID1 does. The profile attributes and constraints are defined in the raid table and used by the same code that already handles the 2- and 3-copy RAID1. The minimum number of devices is 4, the maximum number of devices/chunks that can be lost/damaged is 3. There is no comparable traditional RAID level, the profile is added for future needs to accompany triple-parity and beyond. Signed-off-by: David Sterba

btrfs: add support for 3-copy replication (raid1c3)

2019-11-18T16:51:49Z

Add new block group profile to store 3 copies in a simliar way that current RAID1 does. The profile attributes and constraints are defined in the raid table and used by the same code that already handles the 2-copy RAID1. The minimum number of devices is 3, the maximum number of devices/chunks that can be lost/damaged is 2. Like RAID6 but with 33% space utilization. Signed-off-by: David Sterba

btrfs: replace: BTRFS_DEV_REPLACE_ITEM_STATE_x defines should go

2019-09-09T12:59:11Z

The BTRFS_DEV_REPLACE_ITEM_STATE_x defines, as shown in [1], are unused in both kernel and btrfs-progs (except for one instance of BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED in kernel). [1] btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_FINISHED 2 btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_CANCELED 3 btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED 4 Further these define-values are different form its counterpart BTRFS_IOCTL_DEV_REPLACE_STATE_x series as shown in [2]. [2] btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_SUSPENDED 2 btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_FINISHED 3 btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_CANCELED 4 So this patch deletes the BTRFS_DEV_REPLACE_ITEM_STATE_x altogether, and one instance of BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED is replaced with BTRFS_IOCTL_DEV_REPLACE_STATE_NEVER_STARTED in the kernel.

btrfs: add mask for all RAID1 types

2019-07-02T10:30:48Z

Preparatory patch for additional RAID1 profiles with more copies. The mask will contain 3-copy and 4-copy, most of the checks for plain RAID1 work the same for the other profiles. Signed-off-by: David Sterba

btrfs: use common file type conversion

2019-04-29T17:02:29Z

Deduplicate the btrfs file type conversion implementation - file systems that use the same file types as defined by POSIX do not need to define their own versions and can use the common helper functions decared in fs_types.h and implemented in fs_types.c Common implementation can be found via commit: bbe7449e2599 "fs: common implementation of file type" Reviewed-by: Jan Kara Signed-off-by: Amir Goldstein Signed-off-by: Phillip Potter Reviewed-by: David Sterba Signed-off-by: David Sterba
