  2. ORI-500 ofd: Fix return code handlings in ofd_write_attr_set()

    Li Wei committed with miketappro Feb 27, 2012
    Niu Yawei told me that he had also seen the status "32" in OST_WRITE RPC
    replies during his local testing and traced it back to a return code
    handling bug in ofd_write_attr_set().  We figured out that the "32" must
    be the filter_fid EA size returned by dt_xattr_get().  Given the time
    this started to appear and the RPC status "32", I believe it is also the
    root cause behind the iozone failures.  This patch fixes the return
    handlings and makes ofd_object_ff_check() to return only zero or
    negative---EA sizes are useless for upper layers.

  3. ORI-509 llog: Ensure names are deleted along with logs

    Li Wei committed with miketappro Feb 24, 2012
    When opening an existing log by name, llog_osd_open() doesn't fill the
    name into the log handle.  If the log handle is then fed into
    llog_osd_destroy() (e.g., in the case of llog_erase()), the name will
    not be deleted from the index, causing the back end file system to be
    corrupted.  This patch fixes this problem by always saving names in log
    handles when opening by name.  Also, a minor fix of the CONFIGS
    directory mode is included.

  4. ORI-390 grant: acquire grant space for precreate

    Johann Lombardi committed with miketappro Nov 8, 2011
    This patch changes the precreate path to acquire grant space.
    This avoids running into the situation where object precreation
    consumes space already granted to clients. Space reserved for object
    creation is hold by the self export.
    An initial amount of space is granted at the end of recovery and more
    space is proactively reserved after each creation request handling.
    Grant checks are also not enforced during recovery and orphan cleanup.
    The patch also fills ddp_inodespace/ddp_grant_frag for ZFS OSD.

  5. ORI-508 grant: release grant when destroying export

    Johann Lombardi committed with miketappro Feb 22, 2012
    Unlike obdfilter, the OFD code only releases grant when disconnecting
    the export and not when destroying it. The problem is that there can
    still be requests in flight under processing at the time
    ofd_obd_disconnect() is invoked and we should still release any
    additional grant space allocated to the evicted export.
    This patch modifies the OFD layer to behave like obdfilter.

    Current OFD doesn't set filter_fid EAs for OST_SETATTR and OST_PUNCH

    This patch also fixes the SUID/SGID handling code for OST_SETATTR and
    OST_PUNCH requests so that SUID/SGID bits are cleared wheneven UID/GIDs
    have been initialized.  To reduce duplicate code, that is implemented by
    introducing a helper function, ofd_attr_handle_ugid().

  17. ORI-453 tests: unlink all files when mdsrate times out

    Johann Lombardi committed with miketappro Jan 9, 2012
    When mdsrate cannot create the requested number of files in the
    allocated timeframe (i.e. the --time option), filenames are not
    necessarily consecutive and can have an index higher than the
    number of files that was actually created. Here is an example:
    0: iters 0 nfiles 100000 time 1 begin 0 end 99998 dirthreads 2.
    1: iters 0 nfiles 100000 time 1 begin 1 end 99999 dirthreads 2.
    0: starting at Mon Jan  9 08:26:07 2012
    1: starting at Mon Jan  9 08:26:07 2012
    0: created 1884 files, last file 'f3766'.
    Rate: 2470.42 eff 2470.59 aggr 1235.29 avg client creates/sec
         (total: 2 threads 2440 creates 1 dirs 2 threads/dir 0.99 secs)
    0: finished at Mon Jan  9 08:26:08 2012
    1: created 556 files, last file 'f1111'.
    1: finished at Mon Jan  9 08:26:08 2012
    2440 files have been created and the last file name was f1111 for
    rank 1 and f3766 for rank 0. Running mdsrate --unlink --nfiles 2440
    in this case would discard all files with an index >= 2440.
    With this patch, each mdsrate task will complete properly and report
    the right number of executed operation as soon as one file is missing
    in the per-task sequence. This behavior can be changed with the
    --ignore and --recreate option which are already available.
    This way, mdsrate --unlink --nfiles 100000 will work fine in the
    example above since it will unlink all the existing files, without
    doing tons of useless lookups.

  30. ORI-367 build: Update lbuild to prepare and build lustre for zfs

    Chris Gearing committed with miketappro Nov 24, 2011
    lbuild has been updated to fetch the spl/zfs source from
    the git repository, build the source against the lustre
    kernel and then provide the appropriate information to the
    lustre build to include the spl/zfs modules appropriately
    The default location for the git repo is
    this can be overridden by exporting SPLZFSGITREPO to point somewhere
    The results of the build at not cached and so a new ticket has been
    raised to add the functionality, this is captured in ORI-426.

  31. LU-474 build: document the build release versions

    Andreas Dilger committed with miketappro Dec 6, 2011
    Update ancient document to better describe the build versions
    and Git tags that are being used today.
    This also re-uses the Gerrit Change-Id to quiet an error that
    spuriously was committed to lustre-dev with a Change-Id that
    is already used on master.  By landing and committing this
    patch to lustre-dev it will quiet the false dependency that
    is printed for every patch on master.

  32. ORI-227 tests: fix for OFD/OSD

    Andreas Dilger committed with miketappro Nov 30, 2011
    Change the /proc paths that to use the new OFD/OSD paths
    on the orion branch.  Otherwise, aborts early because it
    cannot find the OST filesystem.
    Disable for non-ldiskfs filesystems, since it won't work
    there until we have proper in-kernel lfsck support.

  33. ORI-297 build: use unique orion build from master

    Andreas Dilger committed with miketappro Nov 21, 2011
    Make the build version for the orion branch different from that used
    on master, to avoid confusion with the built and installed RPMs.
    This is starting the orion development version at (i.e. pre-
    pre-2.3) so that when we start the actual 2.3 development versions at
    2.2.50 the orion builds will not conflict with those versions.
