* posix-acl: Add assume-permissive option for EACCES debugging / rug-sweeping.Kevin Vigor2017-09-091-0/+14
| | | | | | | | | | | | | Summary: Add assume-permissive option for EACCES debugging / rug-sweeping. Re-fetch permissions when needed if they're absent. This is a port of D5104707 & D5131597 to 3.8 Change-Id: I900fc66876ec8e73b04049f844c428b3d225d4ad Reviewed-on: https://review.gluster.org/18249 Reviewed-by: Shreyas Siravara <sshreyas@fb.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org>
* features/namespace: Add namespace xlator and link into brick graphMichael Goulet2017-09-071-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This translator tags namespaces with a unique hash that corresponds to the top-level directory (right under the gluster root) of the file the fop acts on. The hash information is injected into the call frame by this translator, so this namespace information can later be used to do throttling, QoS and other namespace-specific stats collection and actions in later xlators further down the stack. When the translator can't find a path directly for the fd_t or loc_t, it winds a GET_ANCESTRY_PATH_KEY down to the posix xlator to get the path manually. Caching this namespace information in the inode makes sure that most requests don't need to recalculate the hash, so that typically fops are just doing an inode_ctx_get instead of the more expensive code paths that this xlator can take. Right now the xlator is hard-coded to only hash the top-level directory, but this could be easily extended to more sophisticated matching by modification of the parse_path function. Test Plan: Run `prove -v tests/basic/namespace.t` to see that tagging works.

* Log AFR quorum stats in io-stats translator.Kevin Vigor2017-09-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Add AFR quorum state to io-stats translator. Sample output: { "storage.gluster.nfsd.test-replicate-0.has-quorum": "1", "storage.gluster.nfsd.test-replicate-0.quorum-threshold": "1", "storage.gluster.nfsd.test-replicate-1.has-quorum": "1", "storage.gluster.nfsd.test-replicate-1.quorum-threshold": "1" } The quorum-threshold field shows the number of bricks that can be lost while still maintaining quorum. Negative numbers indicate that quorum has been lost and show the number of bricks that must be brought online to restore quorum. Additionally, I found that the code contained both afr_have_quorum() and afr_has_quorum(), which were mostly cut-n-pasted copies of each other, but with subtle differences. Mercifully, afr_have_quorum() was totally unused, so I nuked it in passing. This is a port of D4089969 to 3.8. Test Plan: Run, observe stats output. Kill brick, observe proper change. fb-smoke.

Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Modify STACK_WIND_TAIL() as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } BUG: 1399018 Change-Id: Ie662ac8f18fa16909376f1e59387bc5b886bd0f9 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15934 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shreyas Siravara <sshreyas@fb.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gfapi needs to provide a function towards applications to free memory that it allocated. Depending on how the application is compiled/linked, it could use a different memory allocator than Gluster itself. Therefore it is not safe for gfapi to request applications to free memory with 'standard' free(). Examples for this are Gluster allocated structures with GF_CALLOC() when memory accounting is enabled (the default). Some gfapi functions use malloc() to allocate memory as a workaround, but the free() from the jemalloc implementation should not be combined with the malloc() from glibc.

Milind's initial patch disables OOM adjustment completely for those environments that do not have this header. However, I'd take another approach that: 1) checks for linux/oom.h in compile-time and defines necessary constants if the header is not present; 2) checks for available OOM API in /proc in run-time and uses it accordingly. This allows OOM to be adjusted properly on RHEL5 (the kernel is pretty new to present /proc API for that) as well as RHEL6 (the kernel has many thing backported including new /proc API). > Reviewed-on: http://review.gluster.org/15587 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Reviewed-by: Niels de Vos <ndevos@redhat.com> > Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Change-Id: I1bc610586872d208430575c149a7d0c54bd82370 BUG: 1383694 Signed-off-by: Oleksandr Natalenko <onatalen@redhat.com> Reviewed-on: http://review.gluster.org/15623 Tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cyclic order Backport of: http://review.gluster.org/15080 When the bricks are brought offline and then online in cyclic order while writes are in progress on a file, thanks to inode refresh in write txns, AFR will mostly fail the write attempt when the only good copy is offline. However, there is still a remote possibility that the file will run into split-brain if the brick that has the lone good copy goes offline *after* the inode refresh but *before* the write txn completes (I call it in-flight split-brain in the patch for ease of reference), requiring intervention from admin to resolve the split-brain before the IO can resume normally on the file. To get around this, the patch does the following things: i) retains the dirty xattrs on the file ii) avoids marking the last of the good copies as bad (or accused) in case it is the one to go down during the course of a write. iii) fails that particular write with the appropriate errno. This way, we still have one good copy left despite the split-brain situation which when it is back online, will be chosen as source to do the heal. > Change-Id: I9ca634b026ac830b172bac076437cc3bf1ae7d8a > BUG: 1363721 > Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> > Reviewed-on: http://review.gluster.org/15080 > Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Ravishankar N <ravishankar@redhat.com> > Reviewed-by: Oleksandr Natalenko <oleksandr@natalenko.name> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit fcb5b70b1099d0379b40c81f35750df8bb9545a5) Change-Id: I157f1025aebd6624fa3d412abc69a4ae6f2fe9e0 BUG: 1367272 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> Signed-off-by: Oleksandr Natalenko <oleksandr@natalenko.name> Reviewed-on: http://review.gluster.org/15221 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: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/14672 One of the consumers of a page aligned buffer would be posix's readv fop on O_DIRECT fds. 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.
