* tiering: remove the translator from build and glusterdAmar Tumballi2018-11-021-219/+0
| | | | | | | | | | | | | Based on the proposal to remove few features as they are not actively maintained [1], removing tier translator from the build.

* tier : Tier as a servicehari gowtham2017-01-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tierd is implemented by separating from rebalance process. The commands affected: 1) Attach tier will trigger this process instead of old one 2) tier start and tier start force will also trigger this process. 3) volume status [tier] will show tier daemon as a process instead of task and normal tier status and tier detach status works. 4) tier stop implemented. 5) detach tier implemented separately along with new detach tier status 6) volume tier volname status will work using the changes. 7) volume set works This patch has separated the tier translator from the legacy DHT rebalance code. It now sends the RPCs from the CLI to glusterd separate to the DHT rebalance code. The daemon is now a service, similar to the snapshot daemon, and can be viewed using the volume status command. The code for the validation and commit phase are the same as the earlier tier validation code in DHT rebalance. The “brickop” phase has been changed so that the status command can use this framework. The service management framework is now used. DHT rebalance does not use this framework. This service framework takes care of : *) spawning the daemon, killing it and other such processes. *) volume set options , which are written on the volfile. *) restart and reconfigure functions. Restart is to restart the daemon at two points 1)after gluster goes down and comes up. 2) to stop detach tier. *) reconfigure is used to make immediate volfile changes. By doing this, we don’t restart the daemon. it has the code to rewrite the volfile for topological changes too (which comes into place during add and remove brick). With this patch the log, pid, and volfile are separated and put into respective directories.

* tier/dht : Attach tier fix layout to run in backgroundJoseph Fernandes2016-03-281-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Spawn a thread for background fix-layout for tier process. 2. Once the fix-layout is completed a marker xttr is set on the root of volume to mark the completion of the background fixlayout, so that even if the tier process is spawned again, fixlayout will not be issued, if it was completed last time. 3. Please note that promotion of legacy files will happen eventually as the ctr lookup heal in the fixlayout slowly heals the ctr db for legacy files OR the ctr lookup heal happend due to a name lookup. 4. When a detach tier is successful in evacuation data from hot tier, we remove the marker xattr is removed. So that next attach tier runs the background tier fixlayout. what is remaining ? 1. Instead of clearing the marker xattr of tiering fix layout at the end of detach start clear it during detach commit. But the issue is detach commit is a glusterd operation and the volume is not mounted in glusterd. The reason we want to do it in detach commit is that if the admin wants to attach the same tier again, then a background fixlayout will be triggered, which would not be needed. 2. Clearing the CTR DB of the cold bricks when there is a detach commit, as it will be having entries which will be stale when the volume is used, with ctr off (ctr is switched off only when we have detach commit.)

* tier/libgfdb: Replacing ASCII query file with binaryJoseph Fernandes2015-11-061-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, when the database was queried we used to save all the queried records in an ASCII format in the query file. This caused issues like filename having ASCII delimiter and used to take a lot of space. The tier.c file also had a lot of parsing code. Here we changed the format of the query file to binary. All the logic of serialization and formating of query record is done by libgfdb. Libgfdb provides API, gfdb_write_query_record() and gfdb_read_query_record(), which the user i.e tier migrator and CTR xlator can use to write to and read from query file. With this binary format we save on disk space i.e reduce to 50% atleast as we are saving GFID's in binary format 16 bytes and not the string format which takes 36 bytes + We are not saving path of the file + we are also saving on ASCII delimiters. The on disk format of query record is as follows, +---------------------------------------------------------------------------+ | Length of serialized query record | Serialized Query Record | +---------------------------------------------------------------------------+ 4 bytes Length of serialized query record | | -------------------------------------------------| | | V Serialized Query Record Format: +---------------------------------------------------------------------------+ | GFID | Link count | <LINK INFO> |..... | FOOTER | +---------------------------------------------------------------------------+ 16 B 4 B Link Length 4 B | | | | -----------------------------| | | | | | V | Each <Link Info> will be serialized as | +-----------------------------------------------+ | | PGID | BASE_NAME_LENGTH | BASE_NAME | | +-----------------------------------------------+ | 16 B 4 B BASE_NAME_LENGTH | | | ------------------------------------------------------------------------| | | V FOOTER is a magic number 0xBAADF00D indicating the end of the record. This also serves as a serialized schema validator.

* cluster/tier: add watermarks and policy driverDan Lambright2015-10-101-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix introduces infrastructure to support different policies for promotion and demotion. Currently the tier feature automatically promotes and demotes files periodically based on access. This is good for testing but too stringent for most real workloads. It makes it difficult to fully utilize a hot tier- data will be demoted before it is touched- its unlikely a 100GB hot SSD will have all its data touched in a window of time. A new parameter "mode" allows the user to pick promotion/demotion polcies. The "test mode" will be used for *.t and other general testing. This is the current mechanism. The "cache mode" introduces watermarks. The watermarks represent levels of data residing on the hot tier. "cache mode" policy: The % the hot tier is full is called P. Do not promote or demote more than D MB or F files. A random number [0-100] is called R. Rules for migration: if (P < watermark_low) don't demote, always promote. if (P >= watermark_low) && (P < watermark_hi) demote if R < P; promote if R > P. if (P > watermark_hi) always demote, don't promote. gluster volume set {vol} cluster.watermark-hi % gluster volume set {vol} cluster.watermark-low % gluster volume set {vol} cluster.tier-max-mb {D} gluster volume set {vol} cluster.tier-max-files {F} gluster volume set {vol} cluster.tier-mode {test|cache} Change-Id: I157f19667ec95aa1d53406041c1e3b073be127c2 BUG: 1257911 Signed-off-by: Dan Lambright <dlambrig@redhat.com> Reviewed-on: http://review.gluster.org/12039 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* tier/dht: unlink fails after lookup in a directoryMohammed Rafi KC2015-09-171-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unlink fails with invalid argument for files that are being present on cold tier, before attaching. All of the fops will be hashed to hot_tier after attach-tier (unless explicitly set the "rule" option). Lookups sent to directory, will eventually search the directory using readdirp, and will populate inode_ctx for the inodes based on the output, in respective dht_xlators. So the readdirp will populate inodes_ctx for the files (that is already present in volume before attaching) in cold-dht only because it got the entries from the cold-tier. So when an unlink comes on such an inode, the lookup associated with the unlink will be send as a re validate request to cold-tier only, since already a lookup was performed on the inode, and the new lookup will succeed. So from the unlink of dht, it will hash to cold-tier but the cached_subvol will be cold, since there is a mismatch in hash and cach , it chose hashed subvolume and will sent the fop to hot dht, and the fops fail with EINVAL from the hot-dht since it does not have inode_ctx stored for that inode (because, no lookup was performed from hot-dht).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Avoid hangs on unmounting NFS on NetBSD NetBSD umount(8) on a NFS mount whose server is gone will wait forever because umount(8) calls realpath(3) and tries to access the mount before it calls unmount(2). The non-portable, NetBSD-specific umount -R flag prevent that behavior. We therefore introduce UMOUNT_F, defined as "umount -f" on Linux and "umount -f -R" on NetBSD to take care of forced unmounts, especially in the NFS case. 2) Enforce usage of force_umount wrapper with timeout Whenever umount is used it should be wrapped in force_umount with tiemout handling. That saves us timing issues, and it handles the NetBSD NFS case. 3) Cleanup kernel cache flush. We used (cd $M0 && umount $M0 ) as a portable kernel cache flush trick, but it does not flush everything we need on Linux. Introduce a drop_cache() shell function that reverts to previously used echo 3 > /proc/sys/vm/drop_caches on Linux, and keeps (cd $M0 && umount $M0 ) on other systems.

So for each volume in the graph a tier-dht xlator will be created. So the graph parser will fail because of the redundant node in graph.

* Tests: use a portable way to flush kernel cacheEmmanuel Dreyfus2015-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Linux, kernel cache can be flushed using echo 3 > /proc/sys/vm/drop_caches This non-portable approach can be replaced by an on-purpose failed attempt to unmount: if the mount point is the current directory and umount is called, the kernel will flush inodes until it realize it cannot complete the operation because root of filesystem is busy: ( cd $M0 ; umount $M0 ) Unfortunately this does not flush everything. Entries may still be present in the kenrel FUSE cache. Using $GFS to mount the filesystem ensure --entry-timeout=0 and clears this problem. Some stall information may also remain in glusterfs caches, and that may have to be adressed by appropriate volume option. For instance tests/bugs/rpc/bug-954057.t needs to disable performance.stat-prefetch. Qtherwise, root's new credentials are not evaluated after root-quash is enabled. The test could also be done with performance.stat-prefetch enabled using various tricks: copying the file to read, creating a hard link on it, or just waiting long enough for metadata cache to expire.

* cluster/dht: Add tier translator.Dan Lambright2015-03-211-0/+116
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].
