| | | | | | | | | | | | | | | | | They were not used at all, just taking space. I've also marked all those that are not common really, but used in just one place - they probably should move there (in follow-up patches) As a test, I've removed from the stripe xlator unused private enums and moved one that was in the common list, but only used in the stripe code, to be a private enum.

* cluster/afr: Refactor internal locking code to allow multiple inodelksPranith Kumar K2018-12-286-798/+366
| | | | | | | | | | | | | | | | For implementing copy_file_range fop, AFR needs to perform two inodelks in the same transaction. This patch brings in the necessary structure to make it easier to do so. Entry-locks in AFR were already taking multiple entry-locks on different inodes with the respective basenames. This patch extends the logic in inodelks to use the same lockee_t structure. This lead to removal of quite a lot of duplicate code present in afr-lk-common.c as both the locks are doing same things except 'winding' part. updates: #536 Change-Id: Ibfce7e3f260bb27b18645152ec680c33866fe0ae Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* socket: Remove redundant in_lock in incoming message handlingKrutika Dhananjay2018-12-262-37/+4
| | | | | | | | | | | | | A given epoll thread can handle only one incoming (POLLIN) request. And until the socket is rearmed for listening, it is guaranteed that there won't be any new incoming requests. As a result, the priv->in_lock which guards the socket proto state machine seems redundant. This patch removes priv->in_lock.

| | | | | | | | | | | | | | | The default value of shard-block-size was changed from 4MB to 64MB sometime back. The script "fallocate"s a 6MB file and expects it to have 1 shard under .shard. This worked when the shard-block-size was 4MB. With the default value now at 64MB, file "file1" won't have any shards under .shard and the stat on the 1st shard's path fails with ENOENT. Changed the script to explicitly set shard-block-size to 4MB. Change-Id: I7f1785922287d16d74c95fa57cbbe12e6e66e4f7 fixes: bz#1656264 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>

* cluster/afr: Allow lookup on root if it is from ADD_REPLICA_MOUNTkarthik-us2018-12-1810-32/+176
| | | | | | | | | | | | | | | | | | | | | Problem: When trying to convert a plain distribute volume to replica-3 or arbiter type it is failing with ENOTCONN error as the lookup on the root will fail as there is no quorum. Fix: Allow lookup on root if it is coming from the ADD_REPLICA_MOUNT which is used while adding bricks to a volume. It will try to set the pending xattrs for the newly added bricks to allow the heal to happen in the right direction and avoid data loss scenarios. Note: This fix will solve the problem of type conversion only in the case where the volume was mounted at least once. The conversion of non mounted volumes will still fail since the dht selfheal tries to set the directory layout will fail as they do that with the PID GF_CLIENT_PID_NO_ROOT_SQUASH set in the frame->root.

* iobuf: Get rid of pre allocated iobuf_pool and use per thread mem poolPoornima G2018-12-189-1311/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of iobuf_pool has two problems: - prealloc of 12.5MB memory, this limits the scale factor of the gluster processes due to RAM requirements - lock contention, as the current implementation has one global iobuf_pool lock. Credits for debugging and addressing the same goes to Krutika Dhananjay <kdhananj@redhat.com>. Issue: #410 Hence changing the iobuf implementation to use per thread mem pool. This may theoritically appear to cause perf dip as there is no preallocation. But per thread mem pool will not have significant perf impact as the last allocated memory is kept alive for subsequent allocs, for some time. The worst case would be if iobufs requested are of random sizes each time. The best case is, if we get iobuf request of the same size. From the perf tests, this patch did not seem to cause any perf decrease. Note that, with this patch, the rdma performance is going to degrade drastically. In one of the previous patchsets we had fixes to not degrade rdma perf, but rdma is not supported and also not tested [1]. Hence the decision was to not have code in rdma that is not tested and not supported.

* performance/ob: make open-behind as a child of quick-readRaghavendra Gowdappa2018-12-181-9/+7
| | | | | | | | | | | | | | | | | With read-after-open being set to yes by default, if open-behind sees any reads, it'll do an open on backend (and hence flush/release later). This means with the current order of quick-read and open-behind, open-behind sees all reads and hence also does open bringing down performance for small file reads. Since for small files, reads are absorbed by quick-read, if quick-read is made a parent of open-behind, ob doesn't witness any reads. For read-only workloads, this means ob doen't do any opens (even with read-after-open yes and use-anonymous-fd no).

* fuse: add --lru-limit optionAmar Tumballi2018-12-1411-87/+395
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* extras: New group volume set command for Samba integrationAnoop C S2018-12-143-2/+15
| | | | | | | | | | | | | | | | | | | # gluster volume set <VOLNAME> group samba List of volume set options from group-samba are aimed at improving the below workloads which consumes time and network hops in SMB world: * Listing of large directories * Negative lookups during creation of files Caching the necessary metadata required for these workloads saves us time and network hops. On the other side we have to ensure correctness(avoiding stale cache) in caching(via md-cache) with the help of cache invalidation in an environment where multiple client access is expected.

* locks: handle "clear locks" xattr in fgetxattr tooCsaba Henk2018-12-143-50/+82
| | | | | | | | | | | | | | The lock clearing procedure was kicked in only in getxattr context. We need it to work the same way if it's triggered via fgetxattr (as is the case with interrupt handling). Also cleaned up the instrumentation a bit (more logs, proper management of allocated data). updates: #465 Change-Id: Icfca26ee181da3b8e15ca3fcf61cd5702e2730c8 Signed-off-by: Csaba Henk <csaba@redhat.com>
* Multiple posix related files: several modificationsYaniv Kaul2018-12-148-238/+173
| | | | | | | | | | | | | | | | | | | | | | | | Just looked at posix.c and related code and performed some changes and cleanups. The only important one is #3 below, but surely the others (#2 and #4) need careful review. Changes to other files are as they were related to code paths in posix.c. I'll send a separate patch for other posix related files. Main changes: 1. Proper initializtion for parameters, where it made sense. 2. Logged outside the lock in several places. 3. Moved from CALLOC to MALLOC where it made sense. 4. Aligned structures. 5. moved dictionary functions to use _sizen where possible. (dict_get() -> dict_get_sizen() for example) Compile-tested only!

| | | | | | | | | | | | | | | | | | | | When using list_for_each_entry(_safe) functions, care needs to be taken that the list passed in are not empty, as these functions are not empty list safe. clag scan reported various points where this this pattern could be caught, and this patch fixes the same. Additionally the following changes are present in this patch, - Added an explicit op_ret setting in error case in the macro MAKE_INODE_HANDLE to address another clang issue reported - Minor refactoring of some functions in quota code, to address possible allocation failures in certain functions (which in turn cause possible empty lists to be passed around) Change-Id: I1e761a8d218708f714effb56fa643df2a3ea2cc7 Updates: bz#1622665 Signed-off-by: ShyamsundarR <srangana@redhat.com>
