* rebalance: Introducing local crawl and parallel migrationSusant Palai2015-04-292-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current patch address two part of the design proposed. 1. Rebalance multiple files in parallel 2. Crawl only bricks that belong to the current node Brief design explanation for the above two points. 1. Rebalance multiple files in parallel: ------------------------------------- The existing rebalance engine is single threaded. Hence, introduced multiple threads which will be running parallel to the crawler. The current rebalance migration is converted to a "Producer-Consumer" frame work. Where Producer is : Crawler Consumer is : Migrating Threads Crawler: Crawler is the main thread. The job of the crawler is now limited to fix-layout of each directory and add the files which are eligible for the migration to a global queue in a round robin manner so that we will use all the disk resources efficiently. Hence, the crawler will not be "blocked" by migration process. Producer: Producer will monitor the global queue. If any file is added to this queue, it will dqueue that entry and migrate the file. Currently 20 migration threads are spawned at the beginning of the rebalance process. Hence, multiple file migration happens in parallel. 2. Crawl only bricks that belong to the current node: -------------------------------------------------- As rebalance process is spawned per node, it migrates only the files that belongs to it's own node for the sake of load balancing. But it also reads entries from the whole cluster, which is not necessary as readdir hits other nodes. New Design: As part of the new design the rebalancer decides the subvols that are local to the rebalancer node by checking the node-uuid of root directory prior to the crawler starts. Hence, readdir won't hit the whole cluster as it has already the context of local subvols and also node-uuid request for each file can be avoided. This makes the rebalance process "more scalable".

* core: Global timer-wheelVenky Shankar2015-04-264-3/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: Replace transaction peers listsKaushal M2015-04-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transaction peer lists were used in GlusterD to peers belonging to a transaction. This was needed to prevent newly added peers performing partial transactions, which could be incorrect. This was accomplished by creating a seperate transaction peers list at the beginning of every transaction. A transaction peers list referenced the peerinfo data structures of the peers which were present at the beginning of the transaction. RCU protection of peerinfos referenced by the transaction peers list is a hard problem and difficult to do correctly. To have proper RCU protection of peerinfos, the transaction peers lists have been replaced by an alternative method to identify peers that belong to a transaction. The alternative method is to the global peers list along with generation numbers to identify peers that should belong to a transaction. This change introduces a global peer list generation number, and a generation number for each peerinfo object. Whenever a peerinfo object is created, the global generation number is bumped, and the peerinfos generation number is set to the bumped global generation. With the above changes, the algorithm to identify peers belonging to a transaction with RCU protection is as follows, - At the beginning of a transaction, the current global generation number is saved - To identify if a peers belonging to the transaction, - Start a RCU read critical section - For each peer in the global peers list, - If the peers generation number is not greater than the saved generation number, continue with the action on the peer - End the RCU read critical section The above algorithm guarantees that, - The peer list is not modified when a transaction is iterating through it - The transaction actions are only done on peers that were present when the transaction started But, as a transaction could iterate over the peers list multiple times, the algorithm cannot guarantee that same set of peers will be selected every time. A peer could get deleted between two iterations of the list within a transaction. This problem existed with transaction peers list as well, but unlike before now it will not lead to invalid memory access and potential crashes. This problem will be addressed seprately.

* bitrot/scrub: Scrubber fixesVenky Shankar2015-04-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a handful of problem with scrubber which are detailed below. Scrubber used to skip objects for verification due to missing fd iterface to fetch versioning extended attributes. Similar to the inode interface, an fd based interface in POSIX is now introduced. Moreover, this patch also fixes potential false reporting by scrubber due to: An object gets dirtied and signed when scrubber is busy calculatingobject checksum. This is fixed by caching the signed version when an object is first inspected for stalenes, i.e., during pre-compute stage. This version is used to verify checksum in the post-compute stage when the signatures are compared for possible corruption. Side effect of _not_ sending signature length during signing resulted in "truncated" signature to be set for an object. Now, at the time of signing, the signature length is sent and is used in place of invoking strlen() to get signature length (which could have possible 00s).

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-047-34/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scrubber performs signature verification for objects that were signed by signer. This is done by recalculating the signature (using the hash algorithm the object was signed with) and verifying it aginst the objects persisted signature. Since the object could be undergoing IO opretaion at the time of hash calculation, the signature may not match objects persisted signature. Bitrot stub provides additional information about the stalesness of an objects signature (determinted by it's versioning mechanism). This additional bit of information is used by scrubber to determine the staleness of the signature, and in such cases the object is skipped verification (although signature staleness is performed twice: once before initiation of hash calculation and another after it (an object could be modified after staleness checks). The implmentation is a part of the bitrot xlator (signer) which acts as a signer or scrubber based on a translator option. As of now the scrub process is ever running (but has some form of weak throttling mechanism during filesystem scan). Going forward, there needs to be some form of scrub scheduling and IO throttling (during hash calculation) tunables (via CLI).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* core: Add inode context merge callbackVenky Shankar2015-03-243-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain translators may require to update the inode context of an already linked inode before unwinding the call to the client. Normally, such a case in encountered during parallel operations when a fresh inode is chosen at call (wind) time. In the callback path, one of inodes is successfully linked in the inode table, thereby the other inodes being thrown away (and the inode pointers for these calls being pointed to the linked inode). Translators which may have strict dependency on the correct value in the inode context would get stale values in inode context. This patch introduces a new callback which provides gives translators an opportunity to "patch" their respective inode contexts. Note that, as of now, this callback is only invoked during create()s unwind path. Although this might needed to be done for all dentry fops and lookup, but let that be done as an when required (bitrot stub requires this *only* for create()).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tier translator shares most of DHT's code. It differs in how subvolumes are chosen for I/Os, and how file migration (cache promotion and demotion) is managed. That different functionality is split to either DHT or tier logic according to the "tier_methods" structure. A cache promotion and demotion thread is created in a manner similar to the rebalance daemon. The thread operates a timing wheel which periodically checks for promotion and demotion candidates (files). Candidates are queued and then migrated. Candidates must exist on the same node as the daemon and meet other critera per caching policies. This patch has two authors (Dan Lambright and Joseph Fernandes). Dan did the DHT changes and Joe wrote the cache policies. The fix depends on DHT readidr changes and the database library which have been submitted separately. Header files in libglusterfs/src/gfdb should be reviewed in patch 9683. For more background and design see the feature page [1].

* contrib/timer-wheel: import linux kernel timer-wheelVenky Shankar2015-03-182-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch imports timer-wheel[1] algorithm from the linux kernel (~/kernel/time/timer.c) with some modifications. Timer-wheel is an efficent way to track millions of timers for expiry. This is a variant of the simple but RAM heavy approach of having a list (timer bucket) for every future second. Timer-wheel categorizes every future second into a logarithmic array of arrays. This is done by splitting the 32 bit "timeout" value into fixed "sliced" bits, thereby each category has a fixed size array to which buckets are assigned. A classic split would be 8+6+6+6 (used in this patch) which results in 256+64+64+64 == 512 buckets. Therefore, the entire 32 bit futuristic timeouts have been mapped into 512 buckets. [ NOTE: There are other possible splits, such as "8+8+8+8", but this patch sticks to the widely used and tested default. ] Therfore, the first category "holds" timers whose expiry range is between 1..256, the next cateogry holds 257..16384, third category 16385..1048576 and so on. When timers are added, unless it's in the first category, timers with different timeouts could end up in the same bucket. This means that the timers are "partially sorted" -- sorted in their highest bits. The expiry code walks the first array of buckets and exprires any pending timers (1..256). Next, at time value 257, timers in the first bucket of the second array is "cascaded" onto the first category and timers are placed into respective buckets according to the thier timeout values. Cascading "brings down" the timers timeout to the coorect bucket of their respective category. Therefore, timers are sorted by their highest bits of the timeout value and then by the lower bits too.
