14 years agoHAMMER VFS - Implement REDO recovery code
Matthew Dillon [Fri, 26 Mar 2010 05:42:47 +0000 (22:42 -0700)]
HAMMER VFS - Implement REDO recovery code

* Implement the primary REDO recovery mechanics and document the whole mess.
  REDO recovery essentially works using an expanded UNDO/REDO FIFO range.

  The nominal UNDO range, required for running UNDOs, is calculated first.
  If a REDO_SYNC record is found within this range the record specifies
  the expanded FIFO start offset required to run REDOs.  This is necessary
  because the inodes related to REDOs layed down in the FIFO are not
  necessarily flush in the next flush sequence, so the recovery code may
  have to scan the UNDO/REDO FIFO backwards considerably beyond the nominal
  recovery ranged required to run UNDOs in order to find active REDOs.

  When a REDO_SYNC record is found the recovery code expands the range
  by scanning backwards and validating the UNDO/REDO FIFO as it goes.
  It must make sure that the sequence space remains contiguous all the
  back to the REDO_SYNC point.

  While doing the reverse scan the recovery code collects REDO_TERM_*
  records which are used to mask earlier REDO_* records once their
  meta-data has been flushed.  Only TERM records in the expanded range
  that are outside the nominal UNDO range matter.  Any TERM records in
  the nominal UNDO range refer to meta-data which was undone by the
  stage1 UNDO recovery and so must be ignored (we want to run the
  related REDOs).

  The recovery code then does a forward scan through the entire expanded
  range of the UNDO/REDO FIFO executing any REDO_* records it finds
  which have not been masked by later REDO_TERM_* records.  It executes
  the REDOs using the live filesystem.

* Expand the REDO FIFO structure, I had forgotten to add a localization
  field, otherwise HAMMER doesn't know which PFS the REDO is refering to.

* Umount was improperly flushing the FIFO to the disk for read-only mounts.
  Fix it.

* The recovery code now detects whether any REDOs are present by the
  observation of a REDO_SYNC record in the nominal UNDO recovery range.
  It will not run stage2 (the REDO pass) if it does not see this record.

* Properly generate a REDO_SYNC record in the UNDO space when generating
  only REDOs, as well as UNDOs.  HAMMER was previously only generating
  the REDO_SYNC record when generating UNDOs.

* Generate a REDO_TRUNC record during a file flush if any records were
  previously queued with REDO, even if those records no longer exist
  (e.g. due to a truncation) and even if REDO is now turned off due to
  redo heuristic limits being exceeded.

  This is necessary in order for the recovery code to properly sequence
  REDOs and TRUNCations during recovery.

* For now be very verbose during redo recovery.

* Make sure that mount -o ro and mount -u -o rw work properly.  The
  stage2 REDO cannot be run on a read-only mount because it requires a
  live filesystem.  The operations are defered until the mount is
  upgraded to rw.

kernel - Change the vfs.vm_cycle_point default from 23 to 40

* Large volumes of filesystem activity can cause a lot of data cycling
  to occur and we generally want this cycling to occur within the inactive
  queue where it doesn't push-out idle but strategic pages related to
  resident programs in the active queue.

  A larger vm_cycle_point value will tend to cause VM pages related to
  released buffer cache buffers to be cycled back into the inactive queue,
  leaving the pages in the active queue alone.  A smaller vm_cycle_point
  value will move the more often-used buffer cache buffer pages to the
  active queue when the buffer is released.

* Unfortunately there are typically a lot of VM pages related to resident
  programs such as xterms and databases which can remain idle for long
  periods of time.  Excessive cycling of buffer cache pages to the
  active queue can cause these long-idle pages to be pushed out to
  swap and/or freed.

  This results in an annoyance when these processes go active again,
  particular ssh, xterm, and other interactive programs.  These are
  not necessarily going to perform badly once the pages are paged back
  in, however.

* It has been found that certain large-scale scans of the filesystem such
  as the HAMMER reblocker and overnight cron jobs could push active pages
  out unnecessarily.  Raising vfs.vm_cycle_point to 40 essentially fixes
  this problem but at the cost of potentially starving the 'file cache'
  for data sets which would otherwise fit into memory (and for which the
  sysop might desire to fit into memory).  So YMMV.

14 years agoHAMMER VFS - frontload kmalloc()'s when rebalancing
Matthew Dillon [Sat, 20 Mar 2010 20:01:38 +0000 (13:01 -0700)]
HAMMER VFS - frontload kmalloc()'s when rebalancing

* The rebalancing code must allocate upwards of 16MB of memory to hold
  copies of B-Tree nodes (~64*64*4K).  This is enough to blow out the
  emergency memory reserve used by the pageout daemon and deadlock the
  system in low memory situations.

* Refactor the allocations.  Allocate all the memory up-front so no
  major allocations occur while nodes in the B-Tree are held locked.

* There are probably other cases where this may become a problem.  With
  UFS it wasn't an issue because flushing a file was fairly unsophisticated.
  But with HAMMER certain aspects of the flush require B-Tree lookups and
  can't be dumbed down to a simple raw disk write.

  The rebalancing code was the most aggregious abuser of kernel memory
  though and that should now be fixed.

kernel - Introduce lightweight buffers

 * Summary:
   The lightweight buffer (lwbuf) subsystem is effectively a reimplementation
   of the sfbuf (sendfile buffers) implementation. It was designed to be
   lighter weight than the sfbuf implementation when possible, on x86_64
   we use the DMAP and the implementation is -very- simple. It was also
   designed to be more SMP friendly.

 * Replace all consumption of sfbuf with lwbuf

 * Refactor sfbuf to act as an external refcount mechanism for sendfile(2),
   this will probably go away eventually as well.
