* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* features/bitrot: print the path of the corrupted objectsRaghavendra Bhat2018-05-041-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | Currently "gluster volume bitrot <volume name> scrub status" gives the list of the corrupted objects (files as of now). But only the gfids of those corrupted objects are seen and one has to do getfattr, find etc operations to get the actual path of those objects for removal etc. This change makes an attempt to print the path of those files as much as possible. * Try to get the path using the on disk gfid2path xattr. * If the above operation fails, then go for in memory path (provided that the object has its dentry properly created and linked in the inode table of the brick where the corrupted object is present) So the gfid to path resolution is a soft resolution, i.e. based on the inode and dentry cache in the brick's memory. If the path cannot be obtained via inode table also, then only gfid is printed.

* syncop: fix conditional wait bug in parallel dir scanRavishankar N2016-12-091-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The issue as seen by the user is detailed in the BZ but what is happening is if the no. of items in the wait queue == max-qlen, syncop_mt_dir_scan() does a pthread_cond_wait until the launched synctask workers dequeue the queue. But if for some reason the worker fails, the queue is never emptied due to which further invocations of syncop_mt_dir_scan() are blocked forever. Fix: Made some changes to _dir_scan_job_fn - If a worker encounters error while processing an entry, notify the readdir loop in syncop_mt_dir_scan() of the error but continue to process other entries in the queue, decrementing the qlen as and when we dequeue elements, and ending only when the queue is empty. - If the readdir loop in syncop_mt_dir_scan() gets an error form the worker, stop the readdir+queueing of further entries.

After implementing patch http://review.gluster.org/#/c/13733/ indices of the file which is going through update fop will also be present in .glusterfs/indices even if the fop is successful on all the brick. At this time if heal info command is being used, it will also display this file which is actually healthy and does not require any heal. Solution: Take lock on a file corresponding to the indices and inspect xattrs to decide if the file needs heal or not.

* syncop: Add parallel dir scan functionalityPranith Kumar K2016-04-041-0/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this functionality's ideas are contributed by Richard Wareing, in his patch: https://bugzilla.redhat.com/show_bug.cgi?id=1221737#c1 VERY BIG thanks to him :-). After starting porting/testing the patch above, I found a few things we can improve in this patch based on the results we got in testing. 1) We are reading all the indices before we launch self-heals. In some customer cases I worked on there were almost 5million files/directories that needed heal. With such a big number self-heal daemon will be OOM killed if we go this route. So I modified this to launch heals based on a queue length limit. 2) We found that for directory hierarchies, multi-threaded self-heal patch was not giving better results compared to single-threaded self-heal because of the order problems. We improved index xlator to give gfid type to make sure that all directories in the indices are healed before the files that follow in that iteration of readdir output(http://review.gluster.org/13553). In our testing this lead to zero errors of self-heals as we were only doing self-heals in parallel for files and not directories. I think we can further improve self-heal speed for directories by doing name heals in parallel based on similar techniques Richard's patch showed. I think the best thing there would be to introduce synccond_t infra (pthread_cond_t kind of infra for syncops) which I am planning to implement for future releases. 3) Based on 1), 2) and the fact that afr already does retries of the indices in a loop I removed retries again in the threads. 4) After the refactor, the changes required to bring in multi-threaded self-heal for ec would just be ~10 lines, most of it will be about options initialization. Our tests found that we are able to easily saturate network :-). High level description of the final feature: Traditionally self-heal daemon reads the indices (gfids) that need to be healed from the brick and initiates heal one gfid at a time. Goal of this feature is to add parallelization to the way we do self-heals in a way we do not regress in any case but increase parallelization wherever we can. As part of this following knobs are introduced to improve parallelization: 1) We can launch 'max-jobs' number of heals in parallel. 2) We can keep reading indices as long as the wait-q for heals doesn't go over 'max-qlen' passed as arguments to multi-threaded dir_scan. As a first cut, we always do healing of directories in serial order one at a time but for files we launch heals in parallel. In future we can do name-heals of dir in parallel, but this is not implemented as of now. Reason for this is mentioned already in '2)' above. AFR/EC can introduce options like max-shd-threads/wait-qlength which can be set by users to increase the rate of heals when they want. Please note that the options will take effect only for the next crawl.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* features/bit-rot: Implementation of bit-rot xlatorVenky Shankar2015-03-241-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the "Signer" -- responsible for signing files with their checksums upon last file descriptor close (last release()). The event notification facility provided by the changelog xlator is made use of. Moreover, checksums are as of now SHA256 hash of the object data and is the only available hash at this point of time. Therefore, there is no special "what hash to use" type check, although it's does not take much to add various hashing algorithms to sign objects with. Signatures are stored in extended attributes of the objects along with the the type of hashing used to calculate the signature. This makes thing future proof when other hash types are added. The signature infrastructure is provided by bitrot stub: a little piece of code that sits over the POSIX xlator providing interfaces to "get or set" objects signature and it's staleness. Since objects are signed upon receiving release() notification, pre-existing data which are "never" modified would never be signed. To counter this, an initial crawler thread is spawned The crawler scans the entire brick for objects that are unsigned or "missed" signing due to the server going offline (node reboots, crashes, etc..) and triggers an explicit sign. This would also sign objects when bit-rot is enabled for a volume and/or after upgrade.
