* afr: allow I/O when favorite-child-policy is enabledRavishankar N2016-11-279-61/+469
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently, I/O on a split-brained file fails even when the favorite-child-policy is set until the self-heal is complete. Fix: If a valid 'source' is found using the set favorite-child-policy, inspect and reset the afr pending xattrs on the 'sinks' (inside appropriate locks), refresh the inode and then proceed with the read or write transaction. The resetting itself happens in the self-heal code and hence can also happen in the client side background-heal or by the shd's index-heal in addition to the txn code path explained above. When it happens in via heal, we also add checks in undo-pending to not reset the sink xattrs again.

* cluster/afr: Fix deadlock due to compound fopsKrutika Dhananjay2016-11-261-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an afr data transaction is eligible for using eager-lock, this information is represented in local->transaction.eager_lock_on. However, if non-blocking inodelk attempt (which is a full lock) fails, AFR falls back to blocking locks which are range locks. At this point, local->transaction.eager_lock[] per brick is reset but local->transaction.eager_lock_on is still true. When AFR decides to compound post-op and unlock, it is after confirming that the transaction did not use eager lock (well, except for a small bug where local->transaction.locks_acquired[] is not considered). But within afr_post_op_unlock_do(), afr again incorrectly sets the lock range to full-lock based on local->transaction.eager_lock_on value. This is a bug and can lead to deadlock since the locks acquired were range locks and a full unlock is being sent leading to unlock failure and thereby every other lock request (be it from SHD or other clients or glfsheal) getting blocked forever and the user perceives a hang. FIX: Unconditionally rely on the range locks in inodelk object for unlocking when using compounded post-op + unlock. Big thanks to Pranith for helping with the debugging.

* io-cache: Fix a read hangPoornima G2016-11-233-6/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: ===== In certain cases, there was no unwind of read from read-ahead xlator, thus resulting in hang. RCA: ==== In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead of STACK_WIND(). One such case is when inode_ctx for that file is not present (can happen if readdirp was called, and populates md-cache and serves all the lookups from cache). Consider the following graph: ... io-cache (parent) | readdir-ahead | read-ahead ... Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Ideally, STACK_WIND_TAIL() should be modified as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } But for this solution, knowing the type of variable 'next_xl_fn' is a challenge and is not easy. Hence just modifying all the existing callers to pass "FIRST_CHILD (this)" as obj, instead of "FIRST_CHILD (frame->this)".

* performance/io-threads: Exit threads in fini() as wellPranith Kumar K2016-11-212-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: io-threads starts the thread in 'init()' but doesn't clean them up on 'fini()'. It relies on PARENT_DOWN to exit threads but there can be cases where event before PARENT_UP the graph init code can think of issuing fini(). This code path is hit when glfs_init() is called on a volume that is in 'stopped' state. It leads to a crash in ganesha process, because the io-thread tries to access freed memory. Fix: Ideal fix would be to wait for all fops in io-thread list to be completed on PARENT_DOWN, and have fini() do cleanup of threads. Because there is no proper documentation about how PARENT_DOWN/fini are supposed to be used, we are getting different kinds of sequences in different higher level protocols. So for now cleaning up in both PARENT_DOWN and fini(). Fuse doesn't call fini() gfapi is not calling PARENT_DOWN in some cases, so for now I don't see another way out.

* afr,dht,ec: Replace GF_EVENT_CHILD_MODIFIED with event SOME_DESCENDENT_DOWN/UPPoornima G2016-11-217-38/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently these are few events related to child_up/down: GF_EVENT_CHILD_UP : Issued when any of the protocol client connects. GF_EVENT_CHILD_MODIFIED : Issued by afr/dht/ec GF_EVENT_CHILD_DOWN : Issued when any of the protocol client disconnects. These events get modified at the dht/afr/ec layers. Here is a brief on the same. DHT: - All the subvolumes reported once, and atleast one child came up, then GF_EVENT_CHILD_UP is issued - connect GF_EVENT_CHILD_UP is issued - disconnect GF_EVENT_CHILD_MODIFIED is issued - All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued AFR: - First subvolume came up, then GF_EVENT_CHILD_UP is issued - Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED - Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued - Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP, GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes go up or down. Now with md-cache changes, there is a necessity to differentiate between child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and getting rid of GF_EVENT_CHILD_MODIFIED.

| | | | | | | | | | | | | | | | | | | | | | If a remove brick operation is preceded by a fix-layout, running remove-brick status on a node which does not contain any of the bricks that were removed displays fix-layout status. The defrag_cmd variable was not updated in glusterd for the nodes not hosting removed bricks causing the status parsing to go wrong. This is now updated. Also made minor modifications to the spacing in the fix-layout status output.

* jbr: Sending rollback from failed fop to fdlAvra Sengupta2016-11-0818-58/+347
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of a failed fop, the failure is detected by the leader in the jbr-server in two places. First during a quorum check of +ve responses when it receives responses from all the followers. At this point if the fop hasn't been successfully journaled at a quorum of followers (as in there is no merit in trying the fop in the leader as the quorum will never be met), then we fail the fop. Also if this quorum is met, then the fop is tried on the leader, and after the leader completes the fop a quorum check similar to the previous one is done again, this time including the leaders outcome. If quorum is not met, then we fail the fop. In both these cases, when the fop fails we send a -ve ack to the client. With this patch, now we will also send a rollback through a GF_FOP_IPC to all the followers(and also to the leader in the second case of failure). This rollback will contain the index and term number of the fop which failed. This will be recorded in the respective journals of the bricks and will be used to rollback the fop on that brick later. A subsequent write, and it's respective rollback would look something like the following in the journal. The trusted.jbr.term and trusted.jbr.index present in the dict of both the logs, relate them, and the presence of "rollback-fop" in the dict of IPC indicates that it is a rollback fop, and the value 13(stands for GF_FOP_WRITE) indicates what kind of rollback operation it is. === GF_FOP_WRITE fd = <gfid 77f12ea2-ca56-40e3-a46e-ba2308baa035> vector = <158 bytes> offset = 0 (0x0) flags = 32769 (0x8001) xdata = dict { trusted.jbr.term = 0 <2 bytes> trusted.jbr.index = 4 <2 bytes> } === GF_FOP_IPC xdata = dict { trusted.jbr.term = 0 <2 bytes> trusted.jbr.index = 4 <2 bytes> rollback-fop = 13 <3 bytes> } Change-Id: I70b6a143d20697153d58e2f719e34ecd1ed160a5 BUG: 1349385 Signed-off-by: Avra Sengupta <asengupt@redhat.com> Reviewed-on: http://review.gluster.org/14783 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org>

* glusterd/quota: upgrade quota.conf file during an upgradeManikandan Selvaganesh2016-11-075-16/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gfapi: async fops should unref in callbacksRaghavendra Talur2016-11-053-18/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If fd is unref'd at the end of async call then the unref in cbks would lead to double unref and possible crash. Removing duplicate unrefs. Added unref only in failure cases. A simple test case has been added to test async write case. Need to extend the same for other async APIs too. Details: All glfd based calls in libgfapi, except for glfs_open and glfs_close, behave in the same way. At the start of the operation, they take a ref on glfd and fd. At the end of the operation, they unref it. Async calls are a little different as they unref in the cbk function. A successfull open call does not unref either the glfd or fd, thereby functioning as a reference for a OPEN file object. glfs_close makes a syncop_flush call sandwiched between a fd ref and unref(this can be removed, more on this below), followed by a call to glfs_mark_glfd_for_deletion which unrefs glfd and also calls glfs_fd_destroy as a release function thereby doing a unref on fd too. Functionally, there is no problem with how everything works when as described above. However, it is a little non-intuitive that we need to perform a fd_unref as a consequence of a implicit fd_ref that happens within glfs_resolve_fd. As we perform a GF_REF_GET(glfd) at the start of every operation, it would be worthwhile to remove the fd_ref that glfs_resovle_fd takes and do away with explicit fd_unref()s at the end of every operation. This is the same reason why we don't need the fd_ref in glfs_close. This is however not in the scope of this patch.

* posix-acl: check dictionary before using itRajesh Joseph2016-11-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | If extended attributes are not present in md-cache it returns NULL as xattr. posix acl xlator should check for NULL before using xattr. If normal and default ACLs are not set on file then md-cache will not contain system.posix_acl_access and system.posix_acl_default extended attributes in its cache. Therefore posix_acl_lookup_cbk should check xattr before using it, otherwise the logs will get filled with dictionary errors.

* snapshot: Fix the failure to recreate clones with same nameAvra Sengupta2016-11-015-17/+57
| | | | | | | | | | | | | | | | | | | 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.

FLUSH can not be unwind because it's not a legal waiter for those failed write(as func __wb_request_waiting_on() say). and those failed WRITE also can not be ended if fd1 is not closed. fd2 stuck in close syscall. to resolve this issue, we can change the way we determine 2 requests is 'conflict': flush/fsync is not conflict with those write that is not belonged to them. so __wb_pick_winds() can wind the FLUSH op. below is some information when the stuck issue happen: glusterdump logs: [xlator.performance.write-behind.wb_inode] path=/ltp-F9eG0ZSOME/rw-buffered-16436 inode=0x7fdbe8039b9c window_conf=1048576 window_current=249856 transit-size=0 dontsync=0 [.WRITE] request-ptr=0x7fdbe8020200 refcount=1 wound=no generation-number=4 req->op_ret=-1 req->op_errno=116 sync-attempts=3 sync-in-progress=no size=131072 offset=1220608 lied=-1 append=0 fulfilled=0 go=0 [.WRITE] request-ptr=0x7fdbe8068c30 refcount=1 wound=no generation-number=5 req->op_ret=-1 req->op_errno=116 sync-attempts=2 sync-in-progress=no size=118784 offset=1351680 lied=-1 append=0 fulfilled=0 go=0 [.FLUSH] request-ptr=0x7fdbe8021cd0 refcount=1 wound=no generation-number=6 req->op_ret=0 req->op_errno=0 sync-attempts=0 gdb detail about above 3 requests: (gdb) print *((wb_request_t *)0x7fdbe8021cd0) $2 = {all = {next = 0x7fdbe803a608, prev = 0x7fdbe8068c30}, todo = {next = 0x7fdbe803a618, prev = 0x7fdbe8068c40}, lie = {next = 0x7fdbe8021cf0, prev = 0x7fdbe8021cf0}, winds = {next = 0x7fdbe8021d00, prev = 0x7fdbe8021d00}, unwinds = {next = 0x7fdbe8021d10, prev = 0x7fdbe8021d10}, wip = { next = 0x7fdbe8021d20, prev = 0x7fdbe8021d20}, stub = 0x7fdbe80224dc, write_size = 0, orig_size = 0, total_size = 0, op_ret = 0, op_errno = 0, refcount = 1, wb_inode = 0x7fdbe803a5f0, fop = GF_FOP_FLUSH, lk_owner = {len = 8, data = "W\322T\f\271\367y$", '\000' <repeats 1015 times>}, iobref = 0x0, gen = 6, fd = 0x7fdbe800f0dc, wind_count = 0, ordering = {size = 0, off = 0, append = 0, tempted = 0, lied = 0, fulfilled = 0, go = 0}} (gdb) print *((wb_request_t *)0x7fdbe8020200) $3 = {all = {next = 0x7fdbe8068c30, prev = 0x7fdbe803a608}, todo = {next = 0x7fdbe8068c40, prev = 0x7fdbe803a618}, lie = {next = 0x7fdbe8068c50, prev = 0x7fdbe803a628}, winds = {next = 0x7fdbe8020230, prev = 0x7fdbe8020230}, unwinds = {next = 0x7fdbe8020240, prev = 0x7fdbe8020240}, wip = { next = 0x7fdbe8020250, prev = 0x7fdbe8020250}, stub = 0x7fdbe8062c3c, write_size = 131072, orig_size = 4096, total_size = 0, op_ret = -1, op_errno = 116, refcount = 1, wb_inode = 0x7fdbe803a5f0, fop = GF_FOP_WRITE, lk_owner = {len = 8, data = '\000' <repeats 1023 times>}, iobref = 0x7fdbe80311a0, gen = 4, fd = 0x7fdbe805c89c, wind_count = 3, ordering = {size = 131072, off = 1220608, append = 0, tempted = -1, lied = -1, fulfilled = 0, go = 0}} (gdb) print *((wb_request_t *)0x7fdbe8068c30) $4 = {all = {next = 0x7fdbe8021cd0, prev = 0x7fdbe8020200}, todo = {next = 0x7fdbe8021ce0, prev = 0x7fdbe8020210}, lie = {next = 0x7fdbe803a628, prev = 0x7fdbe8020220}, winds = {next = 0x7fdbe8068c60, prev = 0x7fdbe8068c60}, unwinds = {next = 0x7fdbe8068c70, prev = 0x7fdbe8068c70}, wip = { next = 0x7fdbe8068c80, prev = 0x7fdbe8068c80}, stub = 0x7fdbe806746c, write_size = 118784, orig_size = 4096, total_size = 0, op_ret = -1, op_errno = 116, refcount = 1, wb_inode = 0x7fdbe803a5f0, fop = GF_FOP_WRITE, lk_owner = {len = 8, data = '\000' <repeats 1023 times>}, iobref = 0x7fdbe8052b10, gen = 5, fd = 0x7fdbe805c89c, wind_count = 2, ordering = {size = 118784, off = 1351680, append = 0, tempted = -1, lied = -1, fulfilled = 0, go = 0}} you can see they are all on 'todo' queue, and FLUSH op fd is not the same WRITE op fd.
