* Disable brick daemon from incorrect brick directorykrad2017-09-131-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently the bricks can open any mount directory from the given volume. This patch adds a provision to prevent bricks from opening brick directories that aren't created for them. This will help with operating gluster on large scale. We add a new xattr GF_XATTR_BRICK_NAME to the brick directory. When we start a brick daemon, we make sure the path on disk matches with the config provided. For backward compatibility, we ignore if there is no value for GF_XATTR_BRICK_NAME and set the current brick daemon's path as value. We ignore GF_XATTR_BRICK_NAME during healing and reset GF_XATTR_BRICK_NAME on brick replace.

* Remediation for XFS/DIO corruption problem.Jeff Darcy2017-09-123-2/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new volume option, shd-validate-data. When set, the self-heal code will fetch checksums for regular files along with all the usual xattrs. If the file seems OK but the checksums show a data mismatch, and if there is only one replica that's out of step with the others, then we modify the source/sink calculations to force a heal from one of the agreeing replicas to the odd one out. Combined with a tool to put files into the self-heal index (being developed separately), this provides a very rudimentary kind of scrubbing functionality. Validation is now conditional on the "trusted.glusterfs.validate-status" xattr having the specific value of "suspect" to avoid redoing validation (which is expensive) as we find the same file in multiple bricks' indices. When we decide to take action, we update this xattr to "clean" for copies that were in the majority and "repaired" for the odd one out that gets clobbered. We also copy the about-to-be-clobbered copy into an "orphans" directory to facilitate analysis of corruption patterns. The data goes into ${GFID}.data there, while ${GFID}.link is a symlink to the file's old location.

It does this by leveraging the PGFID tracking feature of the POSIX xlator, and examining lookup replies for the PGFID attribute. If detected, the pgfid will be decoded and stored for later use in case the heal fails for whatever reason. Cascading heal failures are handled through recursion. This feature is critical for a couple reasons: 1. General healing predictability - When the SHD attempts to heal a given GFID, it should be able to do so without having to wait for some other dependent heal to take place. 2. Reliability - In some cases the parent directory may require healing, but the req'd entry in the indices/xattrop directory may not exist (e.g. bugs/crashes etc). Prior to PGFID heal support some sort of external script would be required to queue up these heals by using FS specific utilities to lookup the parent directory by hardlink or worse...do a costly full heal to clean them up. 3. Performance - In combination with multi-threaded SHD this feature will make SHD healing _much_ faster as directories with large amount of files to be healed will no longer have to wait for an entry heal to come along, the first file in that directory queued for healing will trigger an entry heal for the directory and this will allow the other files in that directory to be (immediatelly) healed in parallel.

Fix by making bricks honor the GFID requested by the server when a file is created, even if there is a pre-existing one. This fixes the race and has the additional benefit that any clients with the old GFID will get ESTALE accessing the old file instead of silently getting access to a file which differs fromthe one they thought they were accessing. - This is a port of D3122637 to 3.8.

Creation fops posix_pstat() as part of readdirp 1) file is created with uid/gid 0/0 1) does stat of the path that is created just now. 2) Does chown to set the correct uid/gid 3) Sets the acl/user/internal xattrs 4) Sets the gfid on the entry and completes the creation of the file/dir 2) fills the gfid in the iatt If unwind of readdirp hits server xlator before creation fop, then posix-acl remembers uid/gid of the file to be root/root and fails fops like open etc on it. Fix: Reverse the order of filling gfid and filling lstat() values in posix_pstat() so that if there is gfid in iatt buffer uid/gid are valid. >Change-Id: I46caa7f6da7abfa40a0b1d70e35b88de9c64959c >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/15564 >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Smoke: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> BUG: 1386071 Change-Id: I81c4c6e6b8d4037cee9b23da262b254c126c0a19 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/15665 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

If the file size on the data bricks is more than quick-read's max-file-size (64kb default), those bricks don't set the key. Because of this difference in the no. of dict elements, afr triggers metadata heal in lookup code path, in turn leading to extra lookups+inodelks. Fix: Changed afr dict comparison logic to ignore all virtual xattrs and the on-disk ones that we should not be healing.

| | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/15037/ posix_zerofill() implements zerofilling of a given (offset,length) by doing a writev in a loop followed by an optional fsync on the file. fallocate(2) has a FALLOC_FL_ZERO_RANGE flag which does away with all this and provides the same result (from a userspace application point of view) with a single syscall. This patch attempts the zerofill with the latter and falls back to the former if it fails. Tested using a libgfapi based C program on XFS and observed using gdb that posix_zerofill()'s call to fallocate with FALLOC_FL_ZERO_RANGE was a success.

Today the way it works is by getting a page-aligned buffer through calloc, pread()ing into this buffer and then copying its contents into a newly created iobuf's ptr. This results in an extra memcpy() which can be avoided if we could implement an api that would return an iobuf whose ptr is page-aligned. That way the iobuf->ptr can be directly passed to sys_pread() as a parameter by posix translator.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dirent.d_type can contain the type of the directory entry. The 'd_type' struct member in dirent is present in Linux and many BSD flavours. However, filling d_type with correct value requires support from the underlying filesystem. If not, d_type is set to DT_UNKNOWN. XFS added support for d_type as part of their newer version 5 on-disk format. However, this requires Linux >= 3.15, xfsprogs >= 3.2.0 and the bricks to be formatted using the new format. This patch enables posix xlator to set d_type to the right value even when the underlying filesystem does not support it. d_type can be set using information previously fetched by stat() on the dir entry. This will aid FUSE applications to leverage d_type to avoid the expense of calling lstat() if further actions depend on the type of the file.

This results in failure of mkdir. Since striped volumes are always created with dht, some tests associated with stripe also fail.

* arbiter: write performance improvementRavishankar N2016-04-111-14/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The throughput for a 'dd' workload was much less for arbiter configuration when compared to normal replica-3 volume. There were 2 issues: i)arbiter_writev was using the request dict as response dict while unwinding, leading to incorect GLUSTERFS_WRITE_IS_APPEND and GLUSTERFS_OPEN_FD_COUNT values (=4), leading to immediate post-ops because is_afr_delayed_changelog_post_op_needed() failed due to afr_are_multiple_fds_opened() check. ii) The arbiter code in afr was setting local->transaction.{start and len} =0 to take full file locks. What this meant was even for simultaenous but non-overlapping writevs, afr_transaction_eager_lock_init() was not happening because afr_locals_overlap() always stays true. Consequently is_afr_delayed_changelog_post_op_needed() failed due to local->delayed_post_op not being set. Fix: i) Send appropriate response dict values in arbiter_writev. ii) Modify flock params instead of local->transaction.{start and len} to take full file locks in the transaction. Also changed _fill_writev_xdata() in posix to fill rsp_xdata for whatever key is requested for.

* dht: add "nuke" functionality for efficient server-side deletionJeff Darcy2016-04-071-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This turns a special xattr into an rmdir with flags set. When that hits the posix translator on the server side, that causes the file/directory to be moved into the special "landfill" directory. From there, the posix janitor thread will take care of deleting it entirely on the server side - traversing it recursively if necessary. A couple of secondary issues were fixed to make this effective. * FUSE now ensures that setxattr values are NUL terminated. * The janitor thread now gets woken up immediately when something is placed in 'landfill' instead of only when file descriptors need to be closed. * The default landfill-emptying interval was reduced to 10s. To use the feature, issue a setxattr something like this: setfattr -n glusterfs.dht.nuke -v "" /mnt/glusterfs/vol/some_dir The value doesn't actually matter; the mere receipt of a request with this key is sufficient. Some day it might be useful to allow setting a required value as a sort of password, so that only those who know it can access the underlying special functionality.

* storage/posix: send proper iatt attributes for the root inodeRaghavendra Bhat2016-03-263-15/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * changes in posix to send proper iatt attributes for the root directory when ancestry is built. Before posix was filling only the gfid and the inode type in the iatt structure keeping rest of the fields zeros. This was cached by posix-acl and used to send EACCES when some fops came on that object if the uid of the caller is same as the uid of the object on the disk. * getting and setting inode_ctx in function 'posix_acl_ctx_get' is not atomic and can lead to memory leak when there are multiple looups for an inode at same time. This patch fix this problem * Linking an inode in posix_build_ancestry, can cause a race in posix_acl. When parent inode is linked in posix_build_ancestry, and before it reaches posix_acl_readdirp_cbkc, reate/lookup can come on a leaf-inode, as parent-inode-ctx not yet updated in posix_acl_readdirp_cbk, create/lookup can fail with EACCESS.
