* btrfs-progs: check: adjust command line options for the low-memory modeDavid Sterba2016-08-17

* btrfs-progs: check: introduce low memory modeLu Fengqi2016-08-17
| | | | | | | | | | | | | | | | | | | | | | | Introduce a new fsck mode: low memory mode. Old btrfsck is working efficiently but uses some memory for each extent item. This method will ensure extents are only iterated once at extent/chunk tree check process. But since it uses some memory for each extent item, for a large fs with several TB metadata, this can easily eat up memory and cause OOM. To handle such limitation and improve scalability, the new low-memory mode will not use any heap memory to record which extent is checked. Instead it will use extent backref to avoid most of uneeded checks on shared fs/subvolume tree blocks. And with the use forward and backward reference cross check, we can also ensure every tree block is at least checked once.

* btrfs-progs: add option to run balance as daemonAustin S. Hemmelgarn2016-07-26
| | | | | | | | | | | | | | | | | | | | Currently, balance operations are run synchronously in the foreground. This is nice for interactive management, but is kind of crappy when you start looking at automation and similar things. This patch adds an option to `btrfs balance start` to tell it to daemonize prior to running the balance operation, thus allowing us to preform balances asynchronously. The two biggest use cases I have for this are starting a balance on a remote server without establishing a full shell session, and being able to background the balance in a recovery shell (which usually has no job control) so I can still get progress information. Because it simply daemonizes prior to calling the balance ioctl, this doesn't actually need any kernel support. Signed-off-by: Austin S.

* btrfs-progs: add safety delay before starting full balanceDavid Sterba2016-05-02
| | | | | | | | | | | | A short delay with a warning before starting a full balance should improve usability. We have been getting reports from people who run full balance after following some random advice and then get surprised by the performance impact. The countdown is done even when run from scripts, but as the whole balance takes significanly more time, this shouldn't be an issue. Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: Introduce device delete by devidAnand Jain2016-03-14
| | | | | | | | | | | | | | | | | | | | | | | | This patch introduces new option <devid> for the command btrfs device delete <device_path|devid>[..] <mnt> In a user reported issue on a 3-disk-RAID1, one disk failed with its SB unreadable. Now with this patch user will have a choice to delete the device using devid. The other method we could do, is to match the input device_path to the available device_paths with in the kernel. But that won't work in all the cases, like what if user provided mapper path when the path within the kernel is a non-mapper path. This patch depends on the below kernel patch for the new feature to work, however it will fail-back to the old interface for the kernel without the patch Btrfs: Introduce device delete by devid Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>
