  • d0c14a9ee   nilfs2: free unused dat file blocks during garbage collection ... Browse Code »

    As a nilfs2 volume ages, the amount of available disk space decreases
    little by little due to bloat of DAT (disk address translation) metadata
    file. Even if we delete all files in a file system and free their block
    addresses from the DAT file through a garbage collection, empty DAT blocks
    are not freed.

    This fixes the issue by extending the deallocator of block addresses so
    that empty data blocks and empty bitmap blocks of DAT are deleted.

    The following comparison shows the effect of this patch. Each shows disk
    amount information of a nilfs2 volume that we cleaned out by deleting all
    files and running gc after having filled 90% of its capacity.

    Before:
    Filesystem 1K-blocks Used Available Use% Mounted on
    /dev/sda1 500105212 3022844 472072192 1% /test

    After:
    Filesystem 1K-blocks Used Available Use% Mounted on
    /dev/sda1 500105212 16380 475078656 1% /test

  • c7ef972c4   nilfs2: implement calculation of free inodes count ... Browse Code »

    Currently, NILFS2 returns 0 as free inodes count (f_ffree) and current
    used inodes count as total file nodes in file system (f_files):

    df -i
    Filesystem Inodes IUsed IFree IUse% Mounted on
    /dev/loop0 2 2 0 100% /mnt/nilfs2

    This patch implements real calculation of free inodes count. First of
    all, it is calculated total file nodes in file system as
    (desc_blocks_count * groups_per_desc_block * entries_per_group). Then, it
    is calculated free inodes count as difference the total file nodes and
    used inodes count. As a result, we have such output for NILFS2:

    df -i
    Filesystem Inodes IUsed IFree IUse% Mounted on
    /dev/loop0 4194304 2114701 2079603 51% /mnt/nilfs2

  • db38d5ad3   nilfs2: add cache framework for persistent object allocator ... Browse Code »

    This adds setup and cleanup routines of the persistent object
    allocator cache.

    According to ftrace analyses, accessing buffers of the DAT file
    suffers indispensable overhead many times. To mitigate the overhead,
    This introduce cache framework for the persistent object allocator
    (palloc) which the DAT file and ifile are using.

    struct nilfs_palloc_cache represents the cache object per metadata
    file using palloc.

    The cache is initialized through nilfs_palloc_setup_cache() and
    destroyed by nilfs_palloc_destroy_cache(); callers of the former
    function will be added to individual allocators of DAT and ifile on
    successive patches.

    nilfs_palloc_destroy_cache() will be called from nilfs_mdt_destroy()
    if the cache is attached to a metadata file. A companion function
    nilfs_palloc_clear_cache() is provided to allow releasing buffer head
    references independently with the cleanup task. This adjunctive
    function will be used before invalidating pages of metadata file with
    the cache.
