* fuse: add --lru-limit optionAmar Tumballi2018-12-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The inode LRU mechanism is moot in fuse xlator (ie. there is no limit for the LRU list), as fuse inodes are referenced from kernel context, and thus they can only be dropped on request of the kernel. This might results in a high number of passive inodes which are useless for the glusterfs client, causing a significant memory overhead. This change tries to remedy this by extending the LRU semantics and allowing to set a finite limit on the fuse inode LRU. A brief history of problem: When gluster's inode table was designed, fuse didn't have any 'invalidate' method, which means, userspace application could never ask kernel to send a 'forget()' fop, instead had to wait for kernel to send it based on kernel's parameters. Inode table remembers the number of times kernel has cached the inode based on the 'nlookup' parameter. And 'nlookup' field is not used by no other entry points (like server-protocol, gfapi etc). Hence the inode_table of fuse module always has to have lru-limit as '0', which means no limit. GlusterFS always had to keep all inodes in memory as kernel would have had a reference to it. Again, the reason for this is, kernel's glusterfs inode reference was pointer of 'inode_t' structure in glusterfs. As it is a pointer, we could never free it (to prevent segfault, or memory corruption). Solution: In the inode table, handle the prune case of inodes with 'nlookup' differently, and call a 'invalidator' method, which in this case is fuse_invalidate(), and it sends the request to kernel for getting the forget request. When the kernel sends the forget, it means, it has dropped all the reference to the inode, and it will send the forget with the 'nlookup' parameter too. We just need to make sure to reduce the 'nlookup' value we have when we get forget. That automatically cause the relevant prune to happen.

| | | | | | | | | | | | | String functions like sprintf/snprintf/vprintf etc terminates the string with a null character. This makes meset redundant and also incurs some performance penalty. Also added a comment about using GF_MALLOC instead of GF_CALLOC for allocating buffer for strings, targeted by such functions.

* fuse: diagnostic FLUSH interruptCsaba Henk2018-11-062-0/+135
| | | | | | | | | | | | | | | | | | | We add dummy interrupt handling for the FLUSH fuse message. It can be enabled by the "--fuse-flush-handle-interrupt" hidden command line option, or "-ofuse-flush-handle-interrupt=yes" mount option. It serves no other than diagnostic & demonstational purposes -- to exercise the interrupt handling framework a bit and to give an usage example. Documentation is also provided that showcases interrupt handling via FLUSH. Change-Id: I522f1e798501d06b74ac3592a5f73c1ab0590c60 updates: #465 Signed-off-by: Csaba Henk <csaba@redhat.com>

* fuse: add support for kernel writeback cacheCsaba Henk2018-05-042-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added kernel-writeback-cache command line and xlator option for requesting utilisation of the writeback cache of the kernel in FUSE_INIT (see [1]). - Added attr-times-granularity command line and xlator option via which granularity of the {a,m,c}time in stat (attr) data that we support can be indicated to kernel. This is a means to avoid divergence of the attr times between kernel and userspace that could occur with writeback-cache, while still maintaining maximum time precision the FUSE server is capable of (see [2]). - Handling FATTR_CTIME flag in FUSE_SETATTR that indicates presence of ctime in setattr payload. Currently we cannot associate arbitrary ctimes to files on backend, so we just touch them to update their ctimes to current time. Having ctimes in setattr payload is also a side effect of writeback cache (see [3] and [4]).

* client: make fuse direct I/O strategies explicitCsaba Henk2018-03-222-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the --direct-io-mode option has been presented as of being Boolean valued. That is however not exact, as a third behavior is chosen if the option is not specified. We accept now the "auto" value as an explicit choice for the default heuristics, and indicate in the descriptions of the option (which occur in commandline help and in the gluterfs / mount.glusterfs man pages) that auto is the default. The default heuristics was briefly described in the commandline help. We are getting rid of that, because: - it's not the right place to provide such details; - there is no guarantee of keeping the current heuristics so it might go out of sync with reality; - that is already the case to some degree, because the description did not take into account that the default heuristics varies between platforms (on Mac, it's just "off"), and that xlators can also prescribe direct I/O for the file of their choice (see change I3fe3312cd96baa4eecfe1247ab7255b4f455f049).

| | | | | | | | | | | | | | | | With Gluster 4.0 we will not provide the server components for EL6 and older. At one point Gluster 4.x will get GlusterD2, which requires Golang tools in the distribution. EL6 does not contain these at the moment. With this change, it is possible to `./configure --without-server` which prevents building glusterd and the xlators for the bricks. Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

* debug/sink: add xlator to aid in resource leak debuggingNiels de Vos2017-04-252-0/+177
| | | | | | | | | | | | | | | | | | | | | | This new xlator does not allocate any resources on init(). This makes it a good option to use for debugging xlator releated resources leaks on fini(). By putting the sink xlator as single xlator in a .vol file, and loading it through gfapi, we can investigate the resource leaks that are happening through gfapi (and the Gluster core). By extending the .vol file with additional xlators, it is possible to analyze resource leaks of single xlators.

* glusterd: Add client details to get-state outputSamikshan Bairagya2017-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This commit optionally adds client details corresponding to the locally running bricks to the get-state output. Since getting the client details involves sending RPC requests to the respective local bricks, this is a relatively more costly operation. These client details would be added to the get-state output only if the get-state command is invoked with the 'detail' option. This commit therefore also changes the get-state CLI usage. The modified usage is as follows: # gluster get-state [<daemon>] [[odir </path/to/output/dir/>] \ [file <filename>]] [detail] Change-Id: I42cd4ef160f9e96d55a08a10d32c8ba44e4cd3d8 BUG: 1431183 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: https://review.gluster.org/17003 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* glusterd: add a cli command to trigger a statedump on a clientPoornima G2017-01-231-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no existing CLI that can be used to get the local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The CLI added has the following usage: # gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>] This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (no other daemons are supported as of now) to a file inside the specified output directory. The default output directory and filename is /var/run/gluster and glusterd_state_<timestamp> respectively. The option for specifying the daemon name leaves room to add support for other daemons in the future. Following are the data points captured as of now to represent the state from the local glusterd pov: * Peer: - Primary hostname - uuid - state - connection status - List of hostnames * Volumes: - name, id, transport type, status - counts: bricks, snap, subvol, stripe, arbiter, disperse, redundancy - snapd status - quorum status - tiering related information - rebalance status - replace bricks status - snapshots * Bricks: - Path, hostname (for all bricks these info will be shown) - port, rdma port, status, mount options, filesystem type and signed in status for bricks running locally. * Services: - name, online status for initialised services * Others: - Base port, last allocated port - op-version - MYUUID Change-Id: I4a45cc5407ab92d8afdbbd2098ece851f7e3d618 BUG: 1353156 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/14873 Reviewed-by: Avra Sengupta <asengupt@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
