| * Btrfs-progs: allow dup for data chunks in mixed modeIlya Dryomov2012-03-13
| | | | | | | | | | | | | | | | | | | | Before commit a46e7ff2 was merged it was possible to create dup for data+metadata chunks (mixed mode) by giving -m raid1 -d raid1 -M to mkfs. a46e7ff2 purposefully disabled behind the scenes profile upgrading/downgrading, so give users a chance to pick dup explicitly and bail if dup for data is requested in normal mode.

* | scrub_fs_info( ) file handle leakingGoffredo Baroncelli2012-07-03
| | | | | | | | | | | | | | | | | | The function scrub_fs_info( ) closes and reopen a file handle passed as argument, when a caller uses the file handle even after the call. The function scrub_fs_info( ) is updated to remove the file handle argument, and instead uses a private own file handle. The callers are updated to not pass the argument.
* | btrfs-progs: Update resize documentationShawn Bohrer2012-07-03
| | | | | | | | | | | | | | | | | | | | | | The btrfs filesystem resize command defaults to only resizing the filesystem for devid 1, and must have a devid passed in to resize the filesystem for the other devices in the filesystem. Additionally the documentation lacked information on how to actually resize the underlying partition so this provides a little more detail. Signed-off-by: Shawn Bohrer <shawn.bohrer@gmail.com>

* | btrfs-progs: enforce block count on all devices in mkfsJosef Bacik2012-07-03
| | | | | | | | | | | | | | | | | | | | I had a test that creates a 7gig raid1 device but it was ending up wonky because the second device that gets added is the full size of the disk instead of the limited size. So enforce the limited size on all disks passed in at mkfs time, otherwise our threshold calculations end up wonky when doing chunk allocations. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
* | Btrfs-progs: fix btrfsck's snapshot wrong "unresolved refs"Miao Xie2012-07-03
| | | | | | | | | | | | | | | | | | If the fs/file tree is not the parent of the snapshot, it is reasonable that we can not find the relative reference and back reference. But btrfsck doesn't consider this case, and reports "unresolved refs" message, it's wrong, fix it. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com>

OK, I missed that btrfs_add_to_fsid() increases total size of the filesystem. So now I agree with you. New patch is attached.

Yes, but I don't see a realistic usecase so I don't think it's really worth the work. Honza -- Jan Kara <jack@suse.cz> SUSE Labs, CR >From e5f46872232520310c56327593c02ef6a7f5ea33 Mon Sep 17 00:00:00 2001 From: Jan Kara <jack@suse.cz> Date: Fri, 10 Feb 2012 11:44:44 +0100 Subject: [PATCH] mkfs: Handle creation of filesystem larger than the first device mkfs does not properly check requested size of the filesystem. Thus if the requested size is larger than the first device, it happily creates larger filesystem than a device it resides on which results in 'attemp to access beyond end of device' messages from the kernel. So verify specified filesystem size against the size of the first device. CC: David Sterba <dsterba@suse.cz> Signed-off-by: Jan Kara <jack@suse.cz>

* | Btrfs-progs: make btrfsck aware of free space inodesJosef Bacik2012-06-05
| | | | | | | | | | | | | | | | | | | | | | The new xfstests will run fsck against the volume to make sure we didn't introduce any inconsistencies, which is nice except we will error out immediately if we mount with inode_cache. We need to make btrfsck skip the special free space cache items and then just assume that we have a link for the free space cache inode item. This makes btrfsck pass with success on a fs with inode cache items. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>

* Scan /dev/md and device mapper devices lastChris Mason2012-02-22
| | | | | | | | | | | When we're using multipath or raid0, it is possible that btrfs dev scan will find one of the component devices instead of the proper virtual device the kernel creates. We want to make sure the kernel scans the virtual devices last, since it always remembers the last device it finds with a given fsid. Signed-off-by: Chris Mason <chris.mason@oracle.com>

* btrfsck: remove extents from the fsck reference tracker as they are freedChris Mason2012-02-10
| | | | | | | | | | | | | | | | | | | During btrfsck --repair, we make an index of extents that have incorrect reference counts. Once we've collect the whole index, we go through and modify the extent allocation tree to reflect the correct results. Changing the extent allocation tree may free blocks, and so it may end up removing a block that had a missing reference structure. The fsck code may then circle back around and add the reference back. The result is an extent that isn't actually used, but is recorded in the extent allocation tree. This commit adds a hook called as extents are freed. The hook searches the index of incorrect references and updates it to reflect the freeing of the extent.
