* features/shard: Fill loc.pargfid too for named lookups on individual shardsKrutika Dhananjay2016-11-082-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a sharded volume when a brick is replaced while IO is going on, named lookup on individual shards as part of read/write was failing with ENOENT on the replaced brick, and as a result AFR initiated name heal in lookup callback. But since pargfid was empty (which is what this patch attempts to fix), the resolution of the shards by protocol/server used to fail and the following pattern of logs was seen: Brick-logs: [2016-11-08 07:41:49.387127] W [MSGID: 115009] [server-resolve.c:566:server_resolve] 0-rep-server: no resolution type for (null) (LOOKUP) [2016-11-08 07:41:49.387157] E [MSGID: 115050] [server-rpc-fops.c:156:server_lookup_cbk] 0-rep-server: 91833: LOOKUP(null) (00000000-0000-0000-0000-000000000000/16d47463-ece5-4b33-9c93-470be918c0f6.82) ==> (Invalid argument) [Invalid argument] Client-logs: [2016-11-08 07:41:27.497687] W [MSGID: 114031] [client-rpc-fops.c:2930:client3_3_lookup_cbk] 2-rep-client-0: remote operation failed.

* glusterd/quota: upgrade quota.conf file during an upgradeManikandan Selvaganesh2016-11-074-16/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem ======= When quota is enabled on 3.6, it will have quota conf version in quota.conf as v1.1. This node gets upgraded to 3.7 but it will still have quota conf version as v1.1 until a quota enable/disable/set limit is initiated. When this is not initiated and when this node tries to peer probe a node which is a fresh install of 3.7 (which will have quota conf version as v1.2), then this will result in "Peer rejected" state. This patch fixes the issue. Solution ======== When an upgrade happens from 3.6 to 3.7, quota.conf file needs to be modified as well. With 3.6, in quota.conf the version will be v1.1 and it needs to be changed to v1.2 from 3.7. This is because in 3.7, inode quota feature is introduced. So when an op-version bumpup happens quota.conf needs to be upgraded with quota conf version v1.2 and all the 16 byte uuid needs to be changed to 17 bytes uuid as well. Previously, when the cluster version is upgraded to 3.7, the quota.conf got upgraded as well. But, the upgradation was done only when quota enable/disable/set limit is done. With this patch, the upgradation is done during a cluster op version bump up as well.

| | | | | | | | | | | | | | | | | | | The brick path of snapshot clones contained the clonename, thereby failing to create newer clones with the same name after the original clone had been deleted. This fix creates the brick path with the clone's vol id instead of the clones name. Hence future clones with the same name will not have the namespace clash.

* glusterd: use GF_BRICK_STOPPING as intermediate brickinfo->status stateAtin Mukherjee2016-10-252-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | On a volume stop trigger glusterd issues a brick-op to terminate the brick process during brick-op phase , however in the commit-op glusterd once again tries to kill the same process if it exists and then mark the brickinfo->status flag to GF_BRICK_STOPPED. In the former case, if brick is successfully killed there is a possibility that GlusterD will receive RPC_CLNT_DISCONNECT from the said brick process before even the commit op phase is executed and hence by that time brickinfo->status will still be set to GF_BRICK_STARTED. BRICK_DISCONNECT event should be only sent if a brick has been killed and not through a volume stop/remove brick trigger, however due to this trace, this event is also sent out on a volume stop. Fix is to introduce an intermediate state GF_BRICK_STOPPING which can be used to mark the brick status at brick op phase of volume stop/remove brick to avoid sending spurious BRICK_DISCONNECT events on a volume stop trigger.

* compound fops: Fix file corruption issueKrutika Dhananjay2016-10-243-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Address of a local variable @args is copied into state->req in server3_3_compound (). But even after the function has gone out of scope, in server_compound_resume () this pointer is accessed and dereferenced. This patch fixes that. 2. Compound fops, by virtue of NOT having a vector sizer (like the one writev has), ends up having both the header and the data (in case one of its member fops is WRITEV) in the same hdr_iobuf. This buffer was not being preserved through the lifetime of the compound fop, causing it to be overwritten by a parallel write fop, even when the writev associated with the currently executing compound fop is yet to hit the desk, thereby corrupting the file's data. This is fixed by associating the hdr_iobuf with the iobref so its memory remains valid through the lifetime of the fop. 3. Also fixed a use-after-free bug in protocol/client in compound fops cbk, missed by Linux but caught by NetBSD. Finally, big thanks to Pranith Kumar K and Raghavendra Gowdappa for their help in debugging this file corruption issue.

* md-cache, afr: Reduce the window of stale readPoornima G2016-10-205-116/+323
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider a replica setup, where one mount writes data to a file and the other mount reads the file. In afr, read operations are not transaction based, a brick(read subvolume) is chosen as a part of lookup or other operations, read is always wound only to the read subvolume, even if there was write from a different client that failed on this brick. This stale read continues until there is a lookup or any write operation from the mount point. Currently, this is not a major issue, as a lookup is issued before every read and it will switch the read subvolume to a correct one. But with the plan of increasing md-cache timeout to 600s, the stale read problem will be more pronounced, i.e. stale read can continue for 600s(or more if cascaded with readdirp), as there will be no lookups. Solution: Afr doesn't have any built-in solution for stale read(without affecting the performance). The solution that came up, was to use upcall. When a file on any brick is marked bad for the first time, upcall sends a notification to all the clients that had recently accessed the file. The solution has 2 parts: - Identifying when a file is marked bad, on any of the bricks, for the first time - Client side actions on recieving the notifications Identifying when a file is marked bad on any of the bricks for the first time: ----------------------------------------------------------------------------- The idea is to track xattrop in upcall. xattrop currently comes with 2 afr xattrs - afr dirty bit and afr pending xattrs. Dirty xattr is set to 1 before every write, and is unset if write succeeds. In certain scenarios, dirty xattr can be 0 and still the file could be bad copy. Hence do not track dirty xattr. Pending xattr is set on the good copy, indicating the other bricks that have bad copy. It is still not as simple as, notifying when any of the pending xattrs change. It could lead to flood of notifcations, in case the other brick is completely down or consistantly failing. Hence it is important to notify only once, the first time a good copy is marked bad. Client side actions on recieving pending xattr change, notification: -------------------------------------------------------------------- md-cache will invalidate the cache of that file, so that further lookup is passed down to afr and hence update the read subvolume. Invalidating only in md-cache is not enough, consider the folling oder of opertaions: - pending xattr invalidation - invalidate md-cache - readdirp on the bad read subvolume - fill md-cache - lookup (served from md-cache) - read - wound to the old read subvol. Hence, along with invalidating md-cache, it is very important to reset the read subvolume for that file, in afr. Design Credit: Anuradha Talur, Ravishankar N 1. xattrop doesn't carry info saying post op/pre op. 2. Pre xattrop will have 0 value for all pending xattrs, the cbk of pre xattrop carries the on-disk xattr value. Non zero indicated healing is required. 3. Post xattrop will have non zero value for any of the pending xattrs, if the fop failed on any of the bricks.

The side effect of this is it opens up an window where the pmap_signin event can be initiated by the brick to glusterd and glusterd fails to update signed_in flag since the brickinfo port is still 0 and the comparison of port and brickinfo->port fails. As a solution, set the brickinfo->port post pmap_registry_alloc and if the brick spawn fails reset it to 0. This logic applies for rdma port too.

* performance/write-behind: remove the request from liability queue inRaghavendra G2016-10-161-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wb_fulfill_request Before this patch, a request is removed from liability queue only when ref count of request hits 0. Though, wb_fulfill_request does an unref, it need not be the last unref and hence the request may survive in liability queue till the last unref. Let, T1: the time at which wb_fulfill_request is invoked T2: the time at which last unref is done on request Let's consider a case of T2 > T1. In the time window between T1 and T2, any other request (waiter) conflicting with request in liability queue (blocker - basically a write which has been lied) is blocked from winding. If T2 happens to be when wb_do_unwinds is invoked, no further processing of request list happens and "waiter" would get blocked forever. An example imaginary sequence of events is given below: 1. A write request w1 is picked up for unwinding in __wb_pick_unwinds (but unwind is not done _yet_ and hence reference remains). However, w1 is moved to liability queue. Let's call this invocation of wb_process_queue by wb_writev as PQ1. 2. A flush (f1) request hits write behind. Since the liability queue of inode is not empty, f1 is not picked for unwinding. Let's call the invocation of wb_process_queue by wb_flush as PQ2. 3. PQ2 continues and picks w1 for fulfilling and invokes wb_fulfill. As part of successful wb_fulfill_cbk, wb_fulfill_request (w1) is invoked. But, w1 is not freed (and hence not removed from liability queue) as w1 is not unwound _yet_ and a ref remains (PQ1 has not invoked wb_do_unwinds _yet_). 4. wb_fulfill_cbk (triggered by PQ2) invokes a wb_process_queue (let's say PQ3). f1 is not resumed in PQ3 as w1 is still in liability queue. At this time, PQ2 and PQ3 are complete. 5. PQ1 continues, unwinds w1 and does last unref on w1 and w1 is freed (and removed from liability queue). Since PQ1 didn't invoke wb_fulfill on any other write requests, there won't be any future codepaths that would invoke wb_process_queue and f1 is stuck forever. With this fix, w1 is removed from liability queue in step 3 above and PQ3 resumes f1 in step 4 (as there are no requests conflicting with f1 in liability queue during execution of PQ3).

| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Sharding exposed a bug in arbiter config. where `dd` throughput was extremely slow. Shard xlator was sending a fxattrop to update the file size immediately after a writev. Arbiter was incorrectly over-riding the LLONGMAX-1 start offset (for metadata domain locks) for this fxattrop, causing the inodelk to be taken on the data domain. And since the preceeding writev hadn't released the lock (afr does a 'lazy' unlock if write succeeds on all bricks), this degraded to a blocking lock causing extra lock/unlock calls and delays. Fix: Modify flock.l_len and flock.l_start to take full locks only for data transactions.

* build: out-of-tree builds generates files in the wrong directoryKaleb S KEITHLEY2016-09-1866-166/+270

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

In this patch we set (+1) the dirty flag at the start of the metadata or data update operations and after successfull completion of the fop, we unset (-1) it again.
