* libgfapi: send explicit lookups on inodes linked in readdirpRaghavendra Bhat2015-07-062-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/11236 If the inode is linked via readdirp, then the consuners of gfapi which are using handles (got either in lookup or readdirp) might not send an explicit lookup on that object again (ex: NFS, samba, USS). If there is a replicate volume where the replicas of the object are not in sync, then readdirp followed by fops might lead data being served from the subvolume which is not in sync with latest data. And since lookup is needed to trigger self-heal on that object the consumers might keep getting wrong data until an explicit lookup is not done. Fuse handles this situation by sending an explicit lookup by itself (fuse xlator) on those inodes which are linked via readdirp, whenever a fop comes on that inode. The same procedure is done in gfapi as well to address this situation.

* stack: use list_head for managing framesKrishnan Parthasarathi2015-07-013-91/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM -------- statedump requests that traverse call frames of all call stacks in execution may race with a STACK_RESET on a stack. This could crash the corresponding glusterfs process. For e.g, recently we observed this in a regression test case tests/basic/afr/sparse-self-heal.t. FIX --- gf_proc_dump_pending_frames takes a (TRY_LOCK) call_pool->lock before iterating through call frames of all call stacks in progress. With this fix, STACK_RESET removes its call frames under the same lock. Additional info ---------------- This fix makes call_stack_t to use struct list_head in place of custom doubly-linked list implementation. This makes call_frame_t manipulation easier to maintain in the context of STACK_WIND et al.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/10076/ This patch is part one change to prevent data loss in a replicate volume on doing a replace-brick commit force operation. Problem: After doing replace-brick commit force, there is a chance that self heal happens from the replaced (sink) brick rather than the source brick leading to data loss. Solution: During the commit phase of replace brick, after old brick is brought down, create a temporary mount and perform setfattr operation (on virtual xattr) indicating AFR to mark the replaced brick as sink. As a part of this change replace-brick command is being changed to use mgmt_v3 framework rather than op-state-machine framework. Many thanks to Krishnan Parthasarathi for helping me out on this.

* features/bit-rot-stub: versioning of objects in write/truncate fop instead ↵Raghavendra Bhat2015-05-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of open * This patch brings in the changes where object versioning is done in write and truncate fops instead of tracking them in open and create fops. This model works for both regular and anonymous fds. It also removes the race associated with open calls, create and lookups. This patch follows the below method for object versioning and notifications: Before sending writev on the fd, increase the ongoing version first. This makes anonymous fd write similar to the regular fd write by having the ongoing version increased before doing the write. Do following steps to do versioning: 1) For anonymous fds set the fd context (so that release is invoked) and add the fd context to the list maintained in the inode context. For regular fds the above think would have been done in open itself. 2) Increase the on-disk ongoing version 3) Increase the in memory ongoing version and mark inode as non-dirty 3) Once versioning is successfully done send write operation. If versioning fails, then fail the write fop. 5) In writev_cbk mark inode as modified. > Change-Id: I7104391bbe076d8fc49b68745d2ec29a6e92476c > BUG: 1207979 > Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> > Reviewed-on: http://review.gluster.org/10233 > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Vijay Bellur <vbellur@redhat.com> Change-Id: I4bb86989b5fab02b9ed2950798b1a80e566f1024 BUG: 1220041 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-on: http://review.gluster.org/10722 Reviewed-by: Gaurav Kumar Garg <ggarg@redhat.com> Tested-by: NetBSD Build System Tested-by: Gluster Build System <jenkins@build.gluster.com>
* features/bitrot: Throttle filesystem scrubberVenky Shankar2015-05-104-24/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces multithreaded filesystem scrubber based on throttling option configured for a particular volume. The implementation "logically" breaks scanning and scrubbing with the number of scrubber threads auto-configured depending upon the throttle configuration. Scanning (crawling) is left single threaded (per brick) with entries scrubbed in bulk. On reaching this "bulk" watermark, scanner waits until entries are scrubbed. Bricks for a particular volume have a set of thread(s) assigned for scrubbing, with entries for each brick scrubbed in a round robin fashion to avoid scrub "stalls" when a brick (out of N bricks) is under active scrubbing. This mechanism helps us implement "pause/resume" with ease: all one need to do is to cleanup scrubber threads and let the main scanner thread "wait" untill scrubbing is resumed (where the scrubber thread(s) are spawned again), therefore continuing where we left off (unless we restart the deamons, where crawl initiates from root directory again, but I guess that's OK). [ NOTE: Throttling is optional for the signer daemon, without which it runs full throttle.

* core: Global timer-wheelVenky Shankar2015-05-104-3/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instantiate a process wide global instance of the timer wheel data structure. Spawning glusterfs* process with option arg "--global-timer-wheel" instantiates a global instance of timer-wheel under global context (->ctx). Translators can make use of this process wide instance [via a call to glusterfs_global_timer_wheel()] instead of maintaining an instance of their own and possibly consuming more memory. Linux kernel too has a single instance of timer wheel where subsystems such as IO, networking, etc.. make use of. Bitrot daemon would be early consumers of this: bitrot translator instances for multiple volumes would track objects belonging to their respective bricks in this global expiry tracking data structure. This is also a first step to move GlusterFS timer mechanism to use timer-wheel. > Change-Id: Ie882df607e07acaced846ea269ebf1ece306d6ae > BUG: 1170075 > Signed-off-by: Venky Shankar <vshankar@redhat.com> > Reviewed-on: http://review.gluster.org/10380 > Tested-by: NetBSD Build System > Reviewed-by: Vijay Bellur <vbellur@redhat.com> > Tested-by: Gluster Build System <jenkins@build.gluster.com> Change-Id: I35c840daa9996a059699f8ea5af54c76ede7e09c Signed-off-by: Venky Shankar <vshankar@redhat.com> Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> BUG: 1220041 Reviewed-on: http://review.gluster.org/10716 Tested-by: Gluster Build System <jenkins@build.gluster.com>

* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The key concept here is to determine whether a directory is "clean" by comparing its last-known-good topology to the current one for the volume. These are stored as "commit hashes" on the directory and the volume root respectively. The volume's commit hash changes whenever a brick is added or removed, and a fix-layout is done. A directory's commit hash changes only when a full rebalance (not just fix-layout) is done on it. If all bricks are present and have a directory commit hash that matches the volume commit hash, then we can assume that every file is in its "proper" place. Therefore, if we look for a file in that proper place and don't find it, we can assume it's not on any other subvolume and *safely* skip the global (broadcast to all) lookup.

* bitrot/scrub: fix induced throttling in syncop_ftw_throttle()Venky Shankar2015-05-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Failing to reset scanning counter causes "incorrect" delay of around 50 seconds per directory entry. This causes scrubber to run extremely slowly. [ NOTE: This is a temporary fix. With the introduction of token bucket based throttling, inducing throttle via sleep() call would be unneeded. ] Also, fix logging messages in scrubber to log brick and full path of the object which is identified/marked as corrupted. > Change-Id: Id501bd15dcdbd8a09613f80f9d84050304740027 > BUG: 1170075 > Signed-off-by: Venky Shankar <vshankar@redhat.com> > Reviewed-on: http://review.gluster.org/10375 > Tested-by: NetBSD Build System > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> > Reviewed-by: Gaurav Kumar Garg <ggarg@redhat.com> Change-Id: I78f227f52f12549d62ecb35cbb70121424f7c2a7 BUG: 1220041 Reviewed-on: http://review.gluster.org/10714 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* core: use reference counting for mem_acct structuresJeff Darcy2015-05-0910-174/+193
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When freeing memory, our memory-accounting code expects to be able to dereference from the (previously) allocated block to its owning translator. However, as we have already found once in option validation and twice in logging, that translator might itself have been freed and the dereference attempt causes on of our daemons to crash with SIGSEGV. This patch attempts to fix that as follows: * We no longer embed a struct mem_acct directly in a struct xlator, but instead allocate it separately. * Allocated memory blocks now contain a pointer to the mem_acct instead of the xlator. * The mem_acct structure contains a reference count, manipulated in both the normal and translator allocate/free code using atomic increments and decrements. * Because it's now a separate structure, we can defer freeing the mem_acct until its reference count reaches zero (either way). * Some unit tests were disabled, because they embedded their own copies of the implementation for what they were supposedly testing. Life's too short to spend time fixing tests that seem designed to impede progress by requiring a certain implementation as well as behavior.
