* btrfs-progs: convert: Convert ext inode flags to btrfs inode flagsQu Wenruo2016-10-24
| | | | | | | | | | | | | | | Before this patch, btrfs-convert never copy ext* inode flags to corresponding btrfs inode flags. This makes common flags like APPEND/SYNC/SYNCDIR/IMMUTABLE not copied to btrfs inode. This patch introduces ext2_convert_inode_flags() function to handle the convert, so btrfs-convert can copy as many inode flags as possible.

* btrfs-progs: two staged filesystem creationDavid Sterba2016-08-24
| | | | | | | | | | | | | | | | | | | | | | | | The filesystem existence on a device is manifested by the signature, during the mkfs process we write it first and then create other structures. Such filesystem is not valid and should not be registered during device scan nor listed among devices from blkid. This patch will introduce two staged creation. In the first phase, the signature is wrong, but recognized as a partially created filesystem (by open or scan helpers). Once we successfully create and write everything, we fixup the signature. At this point automated scanning should find a valid filesystem on all devices. We can also rely on the partially created filesystem to do better error handling during creation. We can just bail out and do not need to clean up. The partial signature is '!BHRfS_M', can be shown by btrfs inspect-internal dump-super -F image Reviewed-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: convert: Fix a regression that ext2_save/image is not readonlyQu Wenruo2016-08-19
| | | | | | | | | | | | | | | | | | The new convert treats the convert image as a normal file, without any special flags and permissions. This is different from original code: 1) Permission changed from 0400 to 0600 2) Inode lacks READONLY flag This makes we can read-write mount the ext2 image and cause rollback failure. Follow old code behavior, use 0400 permission and add back READONLY flag to fix it. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: convert: Fix a bug which fails to insert hole file extentQu Wenruo2016-06-07
| | | | | | | | | | | | | | | | | | When copying inode, if there is a file referring part of a hole range, convert will fail. The problem is, when calculating real extent bytenr, it doesn't check if the original extent is a hole. In case the orinal extent is a hole, we still calculate bytenr using file_pos - found_extent_file_pos, causing non-zero value, and later btrfs_record_file_extent() detects that we are pointing to non-exist extent and aborts convert. Fix it by checking the disk_bytenr before calculating real disk bytenr. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: convert: Insert needed holes for superblock migrationQu Wenruo2016-06-07
| | | | | | | | | | | | | | | | | | | New convert doesn't insert holes for superblock migration range. Unlike the old design, which only relocates 4K (superblock size) to other places. In the new design, to make sure convert can handle different page sizes and align chunks bytenr, we relocate the whole 64K range. And if there is only a 4K used block inside 64K superblock migration range, it will make converted the fs have discontiguous file extents. This patch will fix it by inserting needed holes to avoid such discontinuous error.
