* cluster/afr: Send truncate on arbiter brick from SHDkarthik-us2019-03-113-16/+52
| | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume configuration SHD will not send any writes onto the arbiter brick even if there is data pending marker for the arbiter brick. If we have a arbiter setup on the geo-rep master and there are data pending markers for the files on arbiter brick, SHD will not mark any data changelog during healing. While syncing the data from master to slave, if the arbiter-brick is considered as ACTIVE, then there is a chance that slave will miss out some data. If the arbiter brick is being newly added or replaced there is a chance of slave missing all the data during sync. Fix: If there is data pending marker for the arbiter brick, send truncate on the arbiter brick during heal, so that it will record truncate as the data transaction in changelog.

* rpm: add thin-arbiter packageAmar Tumballi2019-03-118-63/+220
| | | | | | | | | | | | | | | | | | | Discussion on thin arbiter volume - https://github.com/gluster/glusterfs/issues/352#issuecomment-350981148 Main idea of having this rpm package is to deploy thin-arbiter without glusterd and other commands on a node, and all we need on that tie-breaker node is to run a single glusterfs command. Also note that, no other glusterfs installation needs thin-arbiter.so. Make sure RPM contains sample vol file, which can work by default, and a script to configure that volfile, along with translator image.

* dict: handle STR_OLD data type in xdr conversionsAmar Tumballi2019-03-082-0/+3
| | | | | | | | | | | | | | | | | Currently a dict conversion on wire for 3.x protocol happens using `dict_unserialize()`, which sets the type of data as STR_OLD. But the new protocol doesn't send it over the wire as its not considered as a valid format in new processes. But considering we deal with old and new protocol when we do a rolling upgrade, it will allow us to get all the information properly with new protocol.

* cluster/afr: Add quorum checks to open & opendir fopskarthik-us2019-03-084-2/+48
| | | | | | | | | | | | | | | Problem: Currently even if open & opendir fails on quorum number of bricks, but succeeds on atleast one brick, it will result in success. This leads to inconsistency in the behaviour with other operations following the open, which has quorum checks. Fix: Add quorum checks to open & opendir fops to avoid inconsistency.

* performance/readdir-ahead: fix deadlockRaghavendra Gowdappa2019-03-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | This deadlock happens while processing dentry corresponding to current directory (.) in rda_fill_readdirp. In this case following order is followed: LOCK(directory_fd_ctx->lock); rda_inode_ctx_get_iatt -> LOCK(directory_inode->lock); However, in rda_mark_inode_dirty following lock order is followed: LOCK(directory_inode->lock); LOCK(directory_fd_ctx->lock); these two codepaths when executed concurrently resulted in a deadlock. Current patch fixes this by removing locking directory inode and fd-ctx in rda_fill_readdirp. This is fine as directory inode's stat won't change due to writes to files within directory.

* WORM-Xlator: Maybe integer overflow when computing new atimeDavid Spisla2019-03-073-8/+12
| | | | | | | | | | | | | | | | | | | | The structs worm_reten_state_t and read_only_priv_t from read-only.h are using uint64_t values to store periods of retention and autocommmit. This seems to be dangerous since in worm-helper.c the function worm_set_state computes in line 97: stbuf->ia_atime = time(NULL) + retention_state->ret_period; stbuf->ia_atime is using int64_t because of the settings of struct iattr. So if there is a very very high retention period stored, there is maybe an integer overflow. What can be the solution? Using int64_t instead if uint64_t may reduce the probability of the occurance.

* io-threads: Prioritize fops with NO_ROOT_SQUASH pidSusant Palai2019-03-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | There was 30% regression observed in mkdir path with commit b139bc58eb504adf5ef81658896c9283ae21f390. On analysis it is found that io-threads xlator deprioritzes fops with all -ve pid. Some context in to the no-root-squash pid requirement: DHT xlator does some of the internal fops with root privileges. This is needed so that operations like layout healing should not be abandoned because a non root user is operating. If root-squash option is enabled the layout set operation looses its root privilege as server xlator converts the uid and pid to random numbers. Hence, the above mentioned commit converted pid to GF_CLIENT_PID_NO_ROOT_SQUASH to continue fops as root. Combining the above I am proposing not to deprioritize fops with no-root-squash pid.

This makes it possible to decrease contention drastically. It's based on wfcqueue structure provided by urcu library. It automatically enables more threads when load demands it, and stops them when not needed. There's a maximum number of threads that can be used. This value can be configured. Depending on the workload, the maximum number of threads plays an important role. So it needs to be configured for optimal performance. Currently the thread pool doesn't self adjust the maximum for the workload, so this configuration needs to be changed manually. For this reason, the global thread pool has been made optional, so that volumes can still use the thread pool provided by io-threads. To enable it for bricks, the following option needs to be set: config.global-threading = on This option has no effect if bricks are already running. A restart is required to activate it. It's recommended to also enable the following option when running bricks with the global thread pool: performance.iot-pass-through = on To enable it for a FUSE mount point, the option '--global-threading' must be added to the mount command. To change it, an umount and remount is needed. It's recommended to disable the following option when using global threading on a mount point: performance.client-io-threads = off To enable it for services managed by glusterd, glusterd needs to be started with option '--global-threading'. In this case all daemons, like self-heal, will be using the global thread pool. Currently it can only be enabled for bricks, FUSE mounts and glusterd services. The maximum number of threads for clients and bricks can be configured using the following options: config.client-threads config.brick-threads These options can be applied online and its effect is immediate most of the times. If one of them is set to 0, the maximum number of threads will be calcutated as #cores * 2. Some distributions use a very old userspace-rcu library (version 0.7) for this reason, some header files from version 0.10 have been copied into contrib/userspace-rcu and are used if the detected version is 0.7 or older. An additional change has been made to io-threads to prevent that threads are started when iot-pass-through is set.

* storage/posix: print the actual file pathRaghavendra Bhat2019-02-141-54/+75
| | | | | | | | | | | | | posix converts incoming operations on files to operations on corresponding gfid handles. While this in itself is not a problem, logging of those gfid handles in place of actual file paths can create confusions during debugging. The best way would be to print both the actual file (recieved as an argument) for path based operations and the gfid handle associated with it.

* cluster/dht: Request linkto xattrs in dht_rmdir opendirN Balachandran2019-02-131-1/+26
| | | | | | | | | | | | | | | | | | If parallel-readdir is enabled, the rda xlator is loaded below dht in the graph and proactively lists and caches entries when an opendir is performed. dht_rmdir checks if the directory being deleted contains stale linkto files by performing a readdirp on its child subvols. However, as the entries are actually read in during the opendir operation which does not request the linkto xattr,no linkto xattrs are present for the entries causing dht to incorrectly identify them as data files and fail the rmdir operation with ENOTEMPTY. DHT now always adds the linkto xattr in the list of xattrs requested in the opendir.
