| * geo-rep: Handle directory sync failure as hard errorKotresh HR2017-04-192-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If directory creation is failed, return immediately before further processing. Allowing it to further process will fail the entire directory tree syncing to slave. Hence master will log and raise exception if it's directory failure. Earlier, master used to log the failure and proceed. > BUG: 1411607 > Signed-off-by: Kotresh HR <khiremat@redhat.com> > Reviewed-on: http://review.gluster.org/16364 > 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: Aravinda VK <avishwan@redhat.com> Change-Id: Iba2a8b5d3d0092e7a9c8a3c2cdf9e6e29c73ddf0 BUG: 1441933 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: https://review.gluster.org/17051 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: Aravinda VK <avishwan@redhat.com>

| * features/shard: Fix vm corruption upon fix-layoutKrutika Dhananjay2017-04-102-59/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: https://review.gluster.org/17010 shard's writev implementation, as part of identifying presence of participant shards that aren't in memory, first sends an MKNOD on these shards, and upon EEXIST error, looks up the shards before proceeding with the writes. The VM corruption was caused when the following happened: 1. DHT had n subvolumes initially. 2. Upon add-brick + fix-layout, the layout of .shard changed although the existing shards under it were yet to be migrated to their new hashed subvolumes. 3. During this time, there were writes on the VM falling in regions of the file whose corresponding shards were already existing under .shard. 4. Sharding xl sent MKNOD on these shards, now creating them in their new hashed subvolumes although there already exist shard blocks for this region with valid data. 5. All subsequent writes were wound on these newly created copies. The net outcome is that both copies of the shard didn't have the correct data. This caused the affected VMs to be unbootable. FIX: For want of better alternatives in DHT, the fix changes shard fops to do a LOOKUP before the MKNOD and upon EEXIST error, perform another lookup.

| * rpcsvc: Add rpchdr and proghdr to iobref before submitting to transportPoornima G2017-04-074-12/+50

In this scenario the client disconnects with rpc decode failed error. RCA: Upcall calls rpcsvc_request_submit to submit the request to socket: rpcsvc_request_submit currently: rpcsvc_request_submit () { iobuf = iobuf_new iov = iobuf->ptr fill iobuf to contain xdrised upcall content - proghdr rpcsvc_callback_submit (..iov..) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit (... iov...) { ... iobuf = iobuf_new iov1 = iobuf->ptr fill iobuf to contain xdrised rpc header - rpchdr msg.rpchdr = iov1 msg.proghdr = iov ... rpc_transport_submit_request (msg) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit assumes that once rpc_transport_submit_request() returns the msg is written on to socket and thus the buffers(rpchdr, proghdr) can be freed, which is not the case. In especially high workload, rpc_transport_submit_request() may not be able to write to socket immediately and hence adds it to its own queue and returns as successful. Thus, we have use after free, for rpchdr and proghdr. Hence the clients gets garbage rpchdr and proghdr and thus fails to decode the rpc, resulting in disconnect. To prevent this, we need to add the rpchdr and proghdr to a iobref and send it in msg: iobref_add (iobref, iobufs) msg.iobref = iobref; The socket layer takes a ref on msg.iobref, if it cannot write to socket and is adding to the queue. Thus we do not have use after free.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: https://review.gluster.org/16961 This fixes a performance issue with shard which was causing the translator to trigger unusually high number of lookups for cache invalidation even when there was no modification to the file. In shard_common_stat_cbk(), it is local->prebuf that contains the aggregated size and block count as opposed to buf which only holds the attributes for the physical copy of base shard. Passing buf for inode_ctx invalidation would always set refresh to true since the file size in inode ctx contains the aggregated size and would never be same as @buf->ia_size. This was leading to every write/read being preceded by a lookup on the base shard even when the file underwent no modification.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When subvolumes crash, users get messages like "No such file or directory" or "I/O Error" when doing operations that are cluster-wide, i.e., operations that touch the subvolume that has crashed. These include operations like mkdir() and rmdir() which are cluster-wide, as well as reads/writes/creates that hash to the dead subvolume. DHT does the right thing by disallowing operations to the subvolume -- it is effectively putting the subvolume in "read-only" mode to protect data, but it does not return the correct error. As a result, users of the filesystem think that the data is gone (in the case of "No such file or directory", or worse a blanket error that means nothing in the case of EIO). DHT sets the errno to ENOENT, which while makes sense in the context of DHT (No subvolume entry, hence ENOENT), the error it should bubble up to the user is EROFS, since it is putting the system in read-only mode. This diff changes the error messages to EROFS so the users get a more clear message of what is going on. Test Plan: Tested by downing a subvolume and checking error codes. Also ran other prove tests to make sure they pass.

It does this by leveraging the PGFID tracking feature of the POSIX xlator, and examining lookup replies for the PGFID attribute. If detected, the pgfid will be decoded and stored for later use in case the heal fails for whatever reason. Cascading heal failures are handled through recursion. This feature is critical for a couple reasons: 1. General healing predictability - When the SHD attempts to heal a given GFID, it should be able to do so without having to wait for some other dependent heal to take place. 2. Reliability - In some cases the parent directory may require healing, but the req'd entry in the indices/xattrop directory may not exist (e.g. bugs/crashes etc). Prior to PGFID heal support some sort of external script would be required to queue up these heals by using FS specific utilities to lookup the parent directory by hardlink or worse...do a costly full heal to clean them up. 3. Performance - In combination with multi-threaded SHD this feature will make SHD healing _much_ faster as directories with large amount of files to be healed will no longer have to wait for an entry heal to come along, the first file in that directory queued for healing will trigger an entry heal for the directory and this will allow the other files in that directory to be (immediatelly) healed in parallel.

Other policies such as majority or size are also possible but not implemented just yet. - Core feature to Halo Geo-Replication, as this (gfid) form of split-brain is an everyday possibility with async mounts, so there needs to be an automated & scalable method to resolve them via the SHD or optionally in-line by FUSE clients or NFS daemons. - Operational notes: 1. Files or directory entries are supported, you can even write files into a directory and they will not be lost. 2. Streamed writes to a files are fully supported while a split-brain resolution happens, i.e. the writes will not be interrupted while the unsplit takes place. 3. Un-split (ones which are determined not to be "authoritative") files are renamed like so: ".<filename>_<random uuid>" Test Plan: - Run prove -v tests/basic/gfid_unsplit.t - Test output: https://phabricator.fb.com/P20041740 Reviewers: moox, dph, sshreyas Reviewed By: sshreyas Differential Revision: https://phabricator.fb.com/D2479409 Signature: t1:2479409:1443208319:373218aa9758a1b48db23ea5e211ec303fa92e64 Blame Revision: Change-Id: I5b3d2e79fad74b4372c02b86219e8ee98f5e29dc Change-Id: I8ef719bcccb19ab6674647e02b72e1b36155fed9 Signed-off-by: Jeff Darcy <jdarcy@fb.com> Reviewed-on: https://review.gluster.org/17720 Smoke: Gluster Build System <jenkins@build.gluster.org> Tested-by: Jeff Darcy <jeff@pl.atyp.us> Reviewed-by: Jeff Darcy <jeff@pl.atyp.us> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
