* geo-rep: minimize xsync crawl usage and set upper limit to xsync crawlAravinda VK2014-07-232-38/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For effective handling of deletes and renames use history crawl as much as possible. History crawl will run in loop till it syncs all data before live changelog time. When it uses xsync crawl(fallback when changelog not available, or very first crawl) it sets upper limit to crawl. After completing History crawl, it checks actual end time returned by history api to compare with register time, if actual end is less than register time then run history crawl one more time. If first turn history processing time is less than the CHANGELOG ROLLOVER TIME then sleep for the difference, After sleep if it is guaranteed that rollover will happen and switches to live changelog consumption without switching to xsync. This sleep is only when history processing completed < CHANGELOG_ROLLOVER_TIME and sleep only after the first turn, So will not affect the performance.

* features/changelog: Capture "correct" internal FOPsVenky Shankar2014-07-234-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes changelog capturing internal FOPs in a cascaded setup, where the intermediate master would record internal FOPs (generated by DHT on link()/rename()). This is due to I/O happening on the intermediate slave on geo-replication's auxillary mount with client-pid -1. Currently, the internal FOP capturing logic depends on client pid being non-negative and the presence of a special key in dictionary. Due to this, internal FOPs on an inter-mediate master would be recorded in the changelog. Checking client-pid being non-negative was introduced to capture AFR self-heal traffic in changelog, thereby breaking cascading setups. By coincidence, AFR self-heal daemon uses -1 as frame->root->pid thereby making is hard to differentiate b/w geo-rep's auxillary mount and self-heal daemon.

* dht: fix rename raceJeff Darcy2014-07-173-3/+112
| | | | | | | | | | | | | | | | | | | | | | | If two clients try to rename the same file at the same time, we sometimes end up with *no file at all* in either the old or new location. That's kind of bad. The culprit seems to be some overly aggressive cleanup code. AFAICT, based on today's study of the code, the intent of the changed section is to remove any linkfile we might have created before the actual rename. However, what we're removing might not be our extra link. If we're racing with another client that's also doing a rename, it might be the only remaining link to the user's data. The solution, which is good enough to pass this test but almost certainly still not complete, is to be more selective about when we do this unlink. Now, we only do it if we know that, at some point, we did in fact create the link without error (notably ENOENT on the source or EEXIST on the destination) ourselves.

* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-167-107/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * There was no handle based API for listxattr. With this change, glfs_h_getxattrs also handles the listxattr functionality by checking whether the name is NULL or not (like posix). But all the gfapi functions for listxattr (glfs_h_getxattrs AND glfs_listxattr AND glfs_flistxattr) returns the names of the xattrs in a buffer provided by the caller. But snapview-server has to return the list of xattrs in a dict itself (similar to posix xlator). But the buffer just contains the names of the xattrs. So for each xattr, a zero byte value is set (i.e. "") into the dict and sent back. Translators which do xattr caching (as of now md-cache which caches selinux and acl related xattrs) should not cache those xattrs whose value is a zero byte data (""). So made changes in md-cache to ignore zero byte values. * NFS server was not linking the inodes to inode table in readdirp. This was leading to applications getting errors. The below set of operations would lead to applications getting error 1) ls -l in one of the snaopshots (snapview-server would generate gfids for each entry on the fly and link the inodes associated with those entries) 2) NFS server upon getting readdirp reply would not link the inodes of the entries. But it used to generate filehandles for each entry and associate the gfid of that entry with the filehandle and send it as part of the reply to nfs client. 3) NFS client would send the filehandle of one of those entries when some activity is done on it. 4) NFS server would not be able to find the inode for the gfid present in the filehandle (as the inode was not linked) and would go for hard resolution by sending a lookup on the gfid by creating a new inode. 5) snapview-client will not able to identify whether the inode is a real inode existing in the main volume or a virtual inode existing in the snapshots as there would not be any inode context. 6) Since the gfid upon which lookup is sent is a virtual gfid which is not present in the disk, lookup would fail and the application would get an error. To handle above situation, now nfs server also does inode linking in readdirp.

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

* features/gfid-access: error handling for entry creationVenky Shankar2014-07-142-1/+39
| | | | | | | | | | | | | | | | | | | | | | | Proceed with setattr() only on a successfull entry creation. Winding a setattr() using a freshlyOC initiated inode would most likely fail in one translator or the other (e.g. DHT expecting the layout information to be set in the inode context), which is the case if the inode was not looked up. Therefore, gfid-access handles failure entry creations and passes the _correct_ errno back to the client instead of continuing with setattr() call and probably returning back incorrect errno. Also, filling up inode->gfid is required as the new inode is not looked up and ->gfid would be certainely required for inode operations.

* dht: support heterogeneous brick sizesJeff Darcy2014-07-127-50/+269
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calculation of layouts now considers the size of each brick, so that smaller bricks don't get an "unfair" share of allocations and start returning ENOSPC while the larger bricks still have plenty of space. The observation has been made that some clients might get ENOTCONN when trying to fetch disk-size information, and end up calculating layouts differently. The following meta-observations can be made. (1) This scenario is extremely unlikely in configurations with AFR. (2) The most likely consequence of this scenario is that some files will be placed sub-optimally by the client with the obsolete (non-weighted) layout. They'll still be found anyway, so this isn't a show stopper. (3) Without this patch it's *guaranteed* that some files will be placed sub-optimally, because any layout that fails to account for brick sizes is sub-optimal. (4) We shouldn't be doing fix-layout from two nodes simultaneously anyway. That's inefficient at best. Any instances of such behavior are separate bugs, which should be fixed separately. (5) In the most extreme edge case, two nodes doing weighted and non-weighted layout fixes could race and end up creating an internally inconsistent layout. This condition is still transient; it will be detected and repaired automatically the next time anyone fetches the layout. (If it's not that's also a preexisting bug that can show up in other contexts.) In conclusion, it's not the purpose of this patch to fix bugs elsewhere in DHT. Its purpose is to make life incrementally better for users who add new hardware with larger disks etc. than the older equipment. It's only one part of an ongoing process to improve layout management and repair, all the way up to support for multiple hash rings or tiering.

* cli/glusterd: Added support for dispersed volumesXavier Hernandez2014-07-1124-37/+1054
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new options have been added to the 'create' command of the cli interface: disperse [<count>] redundancy <count> Both are optional. A dispersed volume is created by specifying, at least, one of them. If 'disperse' is missing or it's present but '<count>' does not, the number of bricks enumerated in the command line is taken as the disperse count. If 'redundancy' is missing, the lowest optimal value is assumed. A configuration is considered optimal (for most workloads) when the disperse count - redundancy count is a power of 2. If the resulting redundancy is 1, the volume is created normally, but if it's greater than 1, a warning is shown to the user and he/she must answer yes/no to continue volume creation. If there isn't any optimal value for the given number of bricks, a warning is also shown and, if the user accepts, a redundancy of 1 is used. If 'redundancy' is specified and the resulting volume is not optimal, another warning is shown to the user. A distributed-disperse volume can be created using a number of bricks multiple of the disperse count.

| | | | | | | | | | | | | | | | | | | | This script was trying to see if the mount process died by doing a 'ps ax' and a grep of the original pid in the results. After that the pid of the first line returned by grep was compared to the original pid. This method can lead to false negatives because it's possible that the original pid appears in some other part of the 'ps ax' list. This patch uses get_mount_process_pid() from volume.rc to check if the process is still alive.

* features/changelog: prevent deadlock on thread cancellationVenky Shankar2014-07-112-0/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | helper threads (fsync, rollover) wake up periodically and perform their respective operation under a lock (crt->lock). These threads are also subjected to cancellation under some circumstance such as disabling changelog. This is inherently dangerous when funtions which are cancellation points for pthread_cancel(3) are used in the locked region. Consider this pthread_mutex_lock(&mutex); { /* ... */ ret = fsync (fd); <-- cancellation point /* ... */ } pthread_mutex_unlock(&mutex); A pthread_cancel(3) by another thread just before fsync(3) but after pthread_mutex_lock(3) would result in the thread getting cancelled when fsync(3) is invoked, thereby never unlocking the mutex. Moreover, in case of changelog translator, the locked region (under crt->lock in changelog-rt.c) is also the code path for fop changelog updation. Therefore, unlocking the mutex in thread cleanup handler (pthread_cleanup_pop(3)) might prematurely release the mutex during fop updation path. This patch fixes such problems existing in fsync and rollover threads. Fix is to enter the locked region with cancellation disabled and enable it after mutex unlock. Also, test for a cancellation request early on in case none of the functions are cancellation points.
