As Park Ju Hyung suggested: "I'd like to suggest to write down an actual version of f2fs-tools here as we've seen older versions of fsck doing even more damage and the users might not have the latest f2fs-tools installed." This patch give a more detailed info of how we fix such corruption to user to avoid damageable repair with low version fsck. Signed-off-by:

The discard thread should issue upto dpolicy->max_requests at once and wait for all those discard requests at once it reaches dpolicy->max_requests. It should then sleep for dpolicy->min_interval timeout before issuing the next batch of discard requests. But in the current code of is_idle(), it checks for dcc_info->queued_discard and aborts issuing the discard batch of max_requests. This dcc_info->queued_discard will be true always once one discard command is issued. It is thus resulting into this type of discard request pattern - - Issue discard request#1 - is_idle() returns false, discard thread waits for request#1 and then sleeps for min_interval 50ms. - Issue discard request#2 - is_idle() returns false, discard thread waits for request#2 and then sleeps for min_interval 50ms. - and so on for all other discard requests, assuming f2fs is idle w.r.t other conditions. With this fix, the pattern will look like this - - Issue discard request#1 - Issue discard request#2 and so on upto max_requests of 8 - Issue discard request#8 - wait for min_interval 50ms.

Two paths to update quota and f2fs_lock_op: 1. - lock_op | - quota_update `- unlock_op 2. - quota_update - lock_op `- unlock_op But, we need to make a transaction on quota_update + lock_op in #2 case.

This ioctl shrinks a given length (aligned to sections) from end of the main area. Any cursegs and valid blocks will be moved out before invalidating the range. This feature can be used for adjusting partition sizes online. History of the patch: Sahitya Tummala: - Add this ioctl for f2fs_compat_ioctl() as well. - Fix debugfs status to reflect the online resize changes. - Fix potential race between online resize path and allocate new data block path or gc path. Others: - Rename some identifiers. - Add some error handling branches. - Clear sbi->next_victim_seg[BG_GC/FG_GC] in shrinking range. - Implement this interface as ext4's, and change the parameter from shrunk bytes to new block count of F2FS. - During resizing, force to empty sit_journal and forbid adding new entries to it, in order to avoid invalid segno in journal after resize. - Reduce sbi->user_block_count before resize starts. - Commit the updated superblock first, and then update in-memory metadata only when the former succeeds. - Target block count must align to sections. - Write checkpoint before and after committing the new superblock, w/o CP_FSCK_FLAG respectively, so that the FS can be fixed by fsck even if resize fails after the new superblock is committed. - In free_segment_range(), reduce granularity of gc_mutex. - Add protection on curseg migration. - Add freeze_bdev() and thaw_bdev() for resize fs. - Remove CUR_MAIN_SECS and use MAIN_SECS directly for allocation. - Recover super_block and FS metadata when resize fails. - No need to clear CP_FSCK_FLAG in update_ckpt_flags(). - Clean up the sb and fs metadata update functions for resize_fs.

f2fs copied all the on-disk i_flags from ext4, and along with it the assumption that the on-disk i_flags are the same as the bits used by FS_IOC_GETFLAGS and FS_IOC_SETFLAGS. This is problematic because reserving an on-disk inode flag in either filesystem's i_flags or in these ioctls effectively reserves it in all the other places too. In fact, most of the "f2fs i_flags" are not used by f2fs at all. Fix this by separating f2fs's i_flags from the ioctl bits and ext4's i_flags. In the process, un-reserve all "f2fs i_flags" that aren't actually supported by f2fs. This included various flags that were not settable at all, as well as various flags that were settable by FS_IOC_SETFLAGS but didn't actually do anything. There's a slight chance we'll need to add some flag(s) back to FS_IOC_SETFLAGS in order to avoid breaking users who expect f2fs to accept some random flag(s). But hopefully such users don't exist.

This extends the checkpoint option to allow checkpoint=disable:%u[%] This allows you to specify what how much of the disk you are willing to lose access to while mounting with checkpoint=disable. If the amount lost would be higher, the mount will return -EAGAIN. This can be given as a percent of total space, or in blocks. Currently, we need to run garbage collection until the amount of holes is smaller than the OVP space. With the new option, f2fs can mark space as unusable up front instead of requiring garbage collection until the number of holes is small enough. Signed-off-by:

Daniel Rosenberg authored
On a remount, you can currently set root reserved if it was not previously set. This can cause an underflow if reserved has been set to a very high value, since then root reserved + current reserved could be greater than user_block_count. inc_valid_block_count later subtracts out these values from user_block_count, causing an underflow.

The existing threshold for allowable holes at checkpoint=disable time is too high. The OVP space contains reserved segments, which are always in the form of free segments. These must be subtracted from the OVP value. The current threshold is meant to be the maximum value of holes of a single type we can have and still guarantee that we can fill the disk without failing to find space for a block of a given type. If the disk is full, ignoring current reserved, which only helps us, the amount of unused blocks is equal to the OVP area. Of that, there are reserved segments, which must be free segments, and the rest of the ovp area, which can come from either free segments or holes. The maximum possible amount of holes is OVP-reserved. Now, consider the disk when mounting with checkpoint=disable. We must be able to fill all available free space with either data or node blocks. When we start with checkpoint=disable, holes are locked to their current type. Say we have H of one type of hole, and H+X of the other. We can fill H of that space with arbitrary typed blocks via SSR. For the remaining H+X blocks, we may not have any of a given block type left at all. For instance, if we were to fill the disk entirely with blocks of the type with fewer holes, the H+X blocks of the opposite type would not be used. If H+X > OVP-reserved, there would be more holes than could possibly exist, and we would have failed to find a suitable block earlier on, leading to a crash in update_sit_entry. If H+X <= OVP-reserved, then the holes end up effectively masked by the OVP region in this case. Signed-off-by:

I used the latest f2fs-tools sent by Chao including "fsck.f2fs: fix to repair cp_loads blocks at correct position" It spit out 140M worth of output, but at least I didn't have to run it twice.
