* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-101-0/+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.

* core: use reference counting for mem_acct structuresJeff Darcy2015-05-0910-170/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* features/bit-rot-stub: versioning of objects in write/truncate fop instead ↵Raghavendra Bhat2015-05-081-1/+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.

* features/bitrot: Throttle filesystem scrubberVenky Shankar2015-05-074-24/+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. However, passing "-DBR_RATE_LIMIT_SIGNER" predefined in CFLAGS enables CPU throttling (during checksum calculation) thereby avoiding high CPU usage. ] Subsequent patches would introduce CPU throttling during hash calculation for scrubber.

* ctr/xlator: Named lookup heal of pre-existing files, before ctr was ON.Joseph Fernandes2015-05-061-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The CTR xlator records file meta (heat/hardlinks) into the data. This works fine for files which are created after ctr xlator is switched ON. But for files which were created before CTR xlator is ON, CTR xlator is not able to record either of the meta i.e heat or hardlinks. Thus making those files immune to promotions/demotions. Solution: The solution that is implemented in this patch is do ctr-db heal of all those pre-existent files, using named lookup. For this purpose we use the inode-xlator context variable option in gluster. The inode-xlator context variable for ctr xlator will have the following, a. A Lock for the context variable b. A hardlink list: This list represents the successful looked up hardlinks. These are the scenarios when the hardlink list is updated: 1) Named-Lookup: Whenever a named lookup happens on a file, in the wind path we copy all required hardlink and inode information to ctr_db_record structure, which resides in the frame->local variable. We dont update the database in wind. During the unwind, we read the information from the ctr_db_record and , Check if the inode context variable is created, if not we create it. Check if the hard link is there in the hardlink list. If its not there we add it to the list and send a update to the database using libgfdb. Please note: The database transaction can fail(and we ignore) as there already might be a record in the db. This update to the db is to heal if its not there. If its there in the list we ignore it. 2) Inode Forget: Whenever an inode forget hits we clear the hardlink list in the inode context variable and delete the inode context variable. Please note: An inode forget may happen for two reason, a. when the inode is delete. b. the in-memory inode is evicted from the inode table due to cache limits. 3) create: whenever a create happens we create the inode context variable and add the hardlink. The database updation is done as usual by ctr. 4) link: whenever a hardlink is created for the inode, we create the inode context variable, if not present, and add the hardlink to the list. 5) unlink: whenever a unlink happens we delete the hardlink from the list. 6) mknod: same as create. 7) rename: whenever a rename happens we update the hardlink in list. if the hardlink was not present for updation, we add the hardlink to the list. What is pending: 1) This solution will only work for named lookups. 2) We dont track afr-self-heal/dht-rebalancer traffic for healing.

* geo-rep: rename handling in dht volumeNithya Balachandran2015-05-052-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: Glusterfs changelogs are stored in each brick, which records the changes happened in that brick. Georep will run in all the nodes of master and processes changelogs "independently". Processing changelogs is in brick level, but all the fops will be replayed on "slave mount" point. Problem: With a DHT volume, in changelog "internal fops" are NOT recorded. For Rename case, Rename is recorded in "hashed" brick changelog. (DHT's internal fops like creating linkto file, unlink is NOT recorded). This lead us to inconsistent rename operations. For example, Distribute volume created with Two bricks B1, B2. //Consider master volume mounted @ /mnt/master and following operations executed: cd /mnt/master touch f1 // f1 falls on B1 Hash mv f1 f2 // f2 falls on B2 Hash // Here, Changelogs are recorded as below: @B1 CREATE f1 @B2 RENAME f1 f2 Here, race exists between Brick B1 and B2, say B2 will get executed first. Source file f1 itself is "NOT PRESENT", so it will go ahead and create f2 (Current implementation). We have this problem When rename falls in another brick and file is unlinked in Master. Similar kind of issue exists in following case too(multiple rename): CREATE f1 RENAME f1 f2 RENAME f2 f1 Solution: Instead of carrying out "changelogging" at "HASHED volume", carry out at the "CACHED volume". This way we have rename operations carried out where actual files are present. So,Changelog recorded as : @B1 CREATE f1 RENAME f1 f2 credit: sarumuga@redhat.com PS: Some of the races as the one below are _NOT_ fixed by this patch * f1 and f2 exist. B1 and B2 are their respective cached subvols. For both files hashed-subvol == cached-subvol * mv f1 f2 on master. * B1 has change-log entry of rename f1 f2 * rebalance migrates f2 from B1 and B2 * mv f2 f1 on master. * B2 has change-log entry of rename f2 f1 Since changelog entries (rename f1 f2) and (rename f2 f1) are processed independently by gsyncds, which of either f1 and f2 survives on slave is subject to race. Note that on master its file f1 with name f1 which survived. On slave it can be either file f1 with name f1 or file f2 with name f2 based on who wins the race of processing changelog.

* 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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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. This change was developed on the git branch at [1]. This commit is a combination of the following commits on the development branch. 52ded5b Add timespec_cmp 44aedd8 Add create timestamp to peerinfo 7bcbea5 Fix some silly mistakes 13e3241 Add start time to opinfo 17a6727 Use timestamp comparisions to identify xaction peers instead of a xaction peer list 3be05b6 Correct check for peerinfo age 70d5b58 Use read-critical sections for peer list iteration ba4dbca Use peerinfo timestamp checks in op-sm instead of xaction peer list d63f811 Add more peer status checks when iterating peers list in glusterd-syncop 1998a2a Timestamp based peer list traversal of mgmtv3 xactions f3c1a42 Remove transaction peer lists b8b08ee Remove unused labels 32e5f5b Remove 'npeers' usage a075fb7 Remove 'npeers' from mgmt-v3 framework 12c9df2 Use generation number instead of timestamps. 9723021 Remove timespec_cmp 80ae2c6 Remove timespec.h include a9479b0 Address review comments on 10147/4 [1]: https://github.com/kshlm/glusterfs/tree/urcu Change-Id: I9be1033525c0a89276f5b5d83dc2eb061918b97f BUG: 1205186 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/10147 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Anand Nekkunti <anekkunt@redhat.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Krishnan Parthasarathi <kparthas@redhat.com>
