      GFS2: Clean up inode creation path · fd4b4e04
      Steven Whitehouse authored
      This patch cleans up the inode creation code path in GFS2. After the
      Orlov allocator was merged, a number of potential improvements are
      now possible, and this is a first set of these.
      The quota handling is now updated so that it matches the point in
      the code where the allocation takes place. This means that the one
      exception in gfs2_alloc_blocks relating to quota is now no longer
      required, and we can use the generic code everywhere.
      In addition the call to figure out whether we need to allocate any
      extra blocks in order to add a directory entry is moved higher up
      gfs2_create_inode. This means that if it returns an error, we
      can deal with that at a stage where it is easier to handle that case.
      The returned status cannot change during the function since we hold
      an exclusive lock on the directory.
      Two calls to gfs2_rindex_update have been changed to one, again at
      the top of gfs2_create_inode to simplify error handling.
      The time stamps are also now initialised earlier in the creation
      process, this is gradually moving towards being able to remove the
      call to gfs2_refresh_inode in gfs2_inode_create once we have all the
      fields covered.

      GFS2: Issue discards in 512b sectors · b2c87cae
      Bob Peterson authored
      This patch changes GFS2's discard issuing code so that it calls
      function sb_issue_discard rather than blkdev_issue_discard. The
      code was calling blkdev_issue_discard and specifying the correct
      sector offset and sector size, but blkdev_issue_discard expects
      these values to be in terms of 512 byte sectors, even if the native
      sector size for the device is different. Calling sb_issue_discard
      with the BLOCK size instead ensures the correct block-to-512b-sector
      translation. I verified that "minlen" is specified in blocks, so
      comparing it to a number of blocks is correct.

      GFS2: Split gfs2_trans_add_bh() into two · 350a9b0a
      Steven Whitehouse authored
      There is little common content in gfs2_trans_add_bh() between the data
      and meta classes by the time that the functions which it calls are
      taken into account. The intent here is to split this into two
      separate functions. Stage one is to introduce gfs2_trans_add_data()
      and gfs2_trans_add_meta() and update the callers accordingly.
      Later patches will then pull in the content of gfs2_trans_add_bh()
      and its dependent functions in order to clean up the code in this

      GFS2: Reset rd_last_alloc when it reaches the end of the rgrp · 13d2eb01
      Bob Peterson authored
      In function rg_mblk_search, it's searching for multiple blocks in
      a given state (e.g. "free"). If there's an active block reservation
      its goal is the next free block of that. If the resource group
      contains the dinode's goal block, that's used for the search. But
      if neither is the case, it uses the rgrp's last allocated block.
      That way, consecutive allocations appear after one another on media.
      The problem comes in when you hit the end of the rgrp; it would never
      start over and search from the beginning. This became a problem,
      since if you deleted all the files and data from the rgrp, it would
      never start over and find free blocks. So it had to keep searching
      further out on the media to allocate blocks. This patch resets the
      rd_last_alloc after it does an unsuccessful search at the end of
      the rgrp.

      GFS2: Add Orlov allocator · 9dbe9610
      Steven Whitehouse authored
      Just like ext3, this works on the root directory and any directory
      with the +T flag set. Also, just like ext3, any subdirectory created
      in one of the just mentioned cases will be allocated to a random
      resource group (GFS2 equivalent of a block group).
      If you are creating a set of directories, each of which will contain a
      job running on a different node, then by setting +T on the parent
      directory before creating the subdirectories, each will land up in a
      different resource group, and thus resource group contention between
      nodes will be kept to a minimum.

      GFS2: Add test for resource group congestion status · bcd97c06
      Steven Whitehouse authored
      This patch uses information gathered by the recent glock statistics
      patch in order to derrive a boolean verdict on the congestion
      status of a resource group. This is then used when making decisions
      on which resource group to choose during block allocation.
      The aim is to avoid resource groups which are heavily contended
      by other nodes, while still ensuring locality of access wherever
      Once a reservation has been made in a particular resource group
      we continue to use that resource group until a new reservation is
      required. This should help to ensure that we do not change resource
      groups too often.

      GFS2: Consolidate free block searching functions · ff7f4cb4
      Steven Whitehouse authored
      With the recently added block reservation code, an additional function
      was added to search for free blocks. This had a restriction of only being
      able to search for aligned extents of free blocks. As a result the
      allocation patterns when reserving blocks were suboptimal when the
      existing allocation of blocks for an inode was not aligned to the same
      This patch resolves that problem by adding the ability for gfs2_rbm_find
      to search for extents of a particular minimum size. We can then use
      gfs2_rbm_find for both looking for reservations, and also looking for
      free blocks on an individual basis when we actually come to do the
      allocation later on. As a result we only need a single set of code
      to deal with both situations.
      The function gfs2_rbm_from_block() is moved up rgrp.c so that it
      occurs before all of its callers.
      Many thanks are due to Bob for helping track down the final issue in
      this patch. That fix to the rb_tree traversal and to not share
      block reservations from a dirctory to its children is included here.

      GFS2: Improve block reservation tracing · 9e733d39
      Steven Whitehouse authored
      This patch improves the tracing of block reservations by
      removing some corner cases and also providing more useful
      detail in the traces.
      A new field is added to the reservation structure to contain
      the inode number. This is used since in certain contexts it is
      not possible to access the inode itself to obtain this information.
      As a result we can then display the inode number for all tracepoints
      and also in case we dump the resource group.
      The "del" tracepoint operation has been removed. This could be called
      with the reservation rgrp set to NULL. That resulted in not printing
      the device number, and thus making the information largely useless
      anyway. Also, the conditional on the rgrp being NULL can then be
      removed from the tracepoint. After this change, all the block
      reservation tracepoint calls will be called with the rgrp information.
      The existing ins,clm and tdel calls to the block reservation tracepoint
      are sufficient to track the entire life of the block reservation.
      In gfs2_block_alloc() the error detection is updated to print out
      the inode number of the problematic inode. This can then be compared
      against the information in the glock dump,tracepoints, etc.

      GFS2: Replace rgblk_search with gfs2_rbm_find · 5b924ae2
      Steven Whitehouse authored
      This is part of a series of patches which are introducing the
      gfs2_rbm structure throughout the block allocation code. The
      main aim of this part is to create a search function which can
      deal directly with struct gfs2_rbm. In this case it specifies
      the initial position at which to start the search and also the
      point at which the search terminates.
      The net result of this is to clean up the search code and make
      it rather more readable, and the various possible exceptions which
      may occur during the search are partitioned into their own functions.
      There are some bug fixes too. We should not be checking the reservations
      while allocating extents - the time for that is when we are searching
      for where to put the extent, not when we've already made that decision.
      Also, rgblk_search had two uses, and in only one of those cases did
      it make sense to check for reservations. This is fixed in the new
      gfs2_rbm_find function, which has a cleaner interface.
      The reservation checking has been improved by always checking for
      contiguous reservations, and returning the first free block after
      all contiguous reservations. This is done under the spin lock to
      ensure consistancy of the tree.
      The allocation of extents is now in all cases done by the existing
      allocation code, and if there is an active reservation, that is updated
      after the fact. Again this is done under the spin lock, since it entails
      changing the lookup key for the reservation in question.

      the tracing was not passing through the inode where it should
      have been. That is mostly fixed aside from one corner case. This
      needs to be revisited since there can also be a NULL rgrp in
      some cases which results in the device being incorrect in the
      This is intended to be the first step towards cleaning up some
      of the allocation code, and some further bug fixes.

      GFS2: Remove rs_requested field from reservations · 71f890f7
      Steven Whitehouse authored
      The rs_requested field is left over from the original allocation
      code, however this should have been a parameter passed to the
      various functions from gfs2_inplace_reserve() and not a member of the
      reservation structure as the value is not required after the
      initial allocation.
      This also helps simplify the code since we no longer need to set
      the rs_requested to zero. Also the gfs2_inplace_release()
      function can also be simplified since the reservation structure
      will always be defined when it is called, and the only remaining
      task is to unlock the rgrp if required. It can also now be
      called unconditionally too, resulting in a further simplification.

      GFS2: Take account of blockages when using reserved blocks · 62e252ee
      Steven Whitehouse authored
      The claim_reserved_blks() function was not taking account of
      the possibility of "blockages" while performing allocation.
      This can be caused by another node allocating something in
      the same extent which has been reserved locally.
      This patch tests for this condition and then skips the remainder
      of the reservation in this case. This is a relatively rare event,
      so that it should not affect the general performance improvement
      which the block reservations provide.
      The claim_reserved_blks() function also appears not to be able
      to deal with reservations which cross bitmap boundaries, but
      that can be dealt with in a future patch since we don't generate
      boundary crossing reservations currently.

      GFS2: Reduce file fragmentation · 8e2e0047
      Bob Peterson authored
      This patch reduces GFS2 file fragmentation by pre-reserving blocks. The
      resulting improved on disk layout greatly speeds up operations in cases
      which would have resulted in interlaced allocation of blocks previously.
      A typical example of this is 10 parallel dd processes, each writing to a
      file in a common dirctory.
      The implementation uses an rbtree of reservations attached to each
      resource group (and each inode).

      GFS2: Use lvbs for storing rgrp information with mount option · 90306c41
      Benjamin Marzinski authored
      Instead of reading in the resource groups when gfs2 is checking
      for free space to allocate from, gfs2 can store the necessary infromation
      in the resource group's lvb.  Also, instead of searching for unlinked
      inodes in every resource group that's checked for free space, gfs2 can
      store the number of unlinked but inodes in the lvb, and only check for
      unlinked inodes if it will find some.
      The first time a resource group is locked, the lvb must initialized.
      Since this involves counting the unlinked inodes in the resource group,
      this takes a little extra time.  But after that, if the resource group
      is locked with GL_SKIP, the buffer head won't be read in unless it's
      actually needed.
      Enabling the resource groups lvbs is done via the rgrplvb mount option.  If
      this option isn't set, the lvbs will still be set and updated, but they won't
      be verfied or used by the filesystem.  To safely turn on this option, all of
      the nodes mounting the filesystem must be running code with this patch, and
      the filesystem must have been completely unmounted since they were updated.
