similar to: [PATCH] fix seekiness due to finding the wrong block group

Hello, So there is an odd case where we can possibly return -ENOSPC when there is in fact space to be had. I think I finally have a hold on what the problem is, it only happens with Metadata writes, and happens _very_ infrequently. What has to happen is we have to allocate have allocated out of the first logical byte on the disk, which would set last_alloc to first_logical_byte(root, 0), so

The whole loop=0,1,2 thing was kind of odd and not very self explanatory. I''ve replaced it with a list_for_each_entry on space_info->block_groups. If we have a hint we just jump into the loop with the block group and start looking for space. If we don''t find anything we start at the beginning and start looking. We never come out of the loop with a ref on the block_group

Hello, This patch adds a new parameter 'full_scan' to 'find_search_start', thereby 'find_search_start' can know whether 'find_free_extent' is in full scan phrase. I feel that 'find_search_start' should skip calling 'btrfs_find_block_group' when 'find_free_extent' is in full scan phrase. In my test on a 2GB volume, Oops occurs when space

Yan Zheng hit a problem where we tried to remove some free space but failed because we couldn''t find the free space entry. This is because the free space was held within a bitmap that had a starting offset well before the actual offset of the free space, and there were free space extents that were in the same range as that offset, so tree_search_offset returned with NULL because we

Rewrite btrfs_drop_extents by using btrfs_duplicate_item, so we can avoid calling lock_extent within transaction.

In trying to track down a weird tree log problem I wanted to make sure that the free space cache was actually valid, which we currently have no way of doing. So this patch adds a bunch of support for the free space cache code and then a checker to fsck. Basically we go through and if we can actually load the free space cache then we will walk the extent tree and verify that the free space cache

Did you check that these groups were actually consistent before you upgraded (have you got a backup to look at the old groups)? The consistency checking definitely got stricter in 4.7, but there may still be a bug here.

Write dirty block groups may allocate new block, thus may add new delayed back ref. btrfs_run_delayed_refs may make some block groups dirty. commit_cowonly_roots does not handle the recursion properly, so some dirty blocks can be left unwritten at commit time. This patch move btrfs_run_delayed_refs into the loop that writes dirty block groups, and make the code not break out of the loop until

I made an attempt to partly decrease fragment by using a preallocated area of multiple size of a std blocksize for a tree block when it is COWed. The basic idea is that if any a tree block need to be created, we offer, say, 2 or 4 multiples of a std blocksize for it, then use the first block in the continuous blocks. When this block need a cow in the future, a new free block in these continuous

I?m trying to setup Spotlight with Tracker (2.3 from Ubuntu repo) backend in Ubuntu 20.04 and Samba 4.12.7. I?ve followed the wiki closely but every time I try to search I get this in the logs: [2020/10/02 10:43:42.078242, 0] ../../source3/rpc_server/mdssvc/mdssvc_tracker.c:403(mds_tracker_search_start) mds_tracker_search_start: no connection to Tracker [2020/10/02 10:43:42.079897, 0]

Hai, Selfcompiles samba? And which one did you use? https://wiki.samba.org/index.php/Spotlight_with_Elasticsearch_Backend Or https://wiki.samba.org/index.php/Spotlight_with_Gnome_Tracker_Backend I think you missed : https://wiki.samba.org/index.php/Spotlight_with_Gnome_Tracker_Backend#Create_a_user_under_which_Tracker_will_run Greetz, Louis > -----Oorspronkelijk bericht----- >

How could I investigate this further? If I monitor session and system dbus activity with dbus-monitor I can see activity if I do ?tracker search pdf? as the mdssvc user, but nothing if I search through Samba. I only get those two errors below. So seems like Samba dbus connection isn?t working. I?ve followed the wiki very closely so to me it looks like it?s missing a step or the latest versions

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

We have been using bytes_reserved for metadata reservations, which is wrong since we use that to keep track of outstanding reservations from the allocator. This resulted in us doing a lot of silly things to make sure we don''t allocate a bunch of metadata chunks since we never had a real view of how much space was actually in use by metadata. There are a lot of fixes in here to make this

Here are 3 patches to avoid undesired aborts of mkfs.btrfs. These are based on top of Chris''s btrfs-progs.git: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git Thanks, H.Seto Hidetoshi Seto (3): btrfs-progs: error if device for mkfs is too small btrfs-progs: error if device have no space to make primary chunks btrfs-progs: calculate available

We discussed using the top bits of the chunk type field field to store a number of redundant disks -- so instead of RAID5, RAID6, etc., we end up with a single ''RAID56'' flag, and the amount of redundancy is stored elsewhere. This attempts it, but I hate it and don''t really want to do it. The type field is designed as a bitmask, and _used_ as a bitmask in a number of
