* rpc : Change the way client uuid is builtPoornima G2017-11-203-27/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Today the main users of client uuid are protocol layers, locks, leases. Protocol layers requires each client uuid to be unique, even across connects and disconnects. Locks and leases on the server side also use the same client uid which changes across file migrations. Which makes the graph switch and file migration tedious for locks and leases. file migration across bricks becomes difficult as client uuid for the same client, is different on the other brick. The exact set of issues exists for leases as well. Solution would be to introduce a constant in the client-uid string which the locks and leases can use to identify the owner client across bricks. Client uuid currently: %s(ctx uuid)-%s(protocol client name)-%d(graph id)%s(setvolume count/reconnect count) Proposed Client uuid: "CTX_ID:%s-GRAPH_ID:%d-PID:%d-HOST:%s-PC_NAME:%s-RECON_NO:%s" - CTX_ID: This is will be constant per client. - GRAPH_ID, PID, HOST, PC_NAME(protocol client name), RECON_NO(setvolume count) remains the same.

* cluster/dht: Don't set ACLs on linkto fileN Balachandran2017-11-191-0/+11
| | | | | | | | | | | | | | The trusted.SGI_ACL_FILE appears to set posix ACLs on the linkto file that is a target of file migration. This can mess up file permissions and cause linkto identification to fail. Now we remove all ACL xattrs from the results of the listxattr call on the source before setting them on the target.

* afr: add checks for allowing lookupsRavishankar N2017-11-186-116/+164
| | | | | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, lookup was being served from one of the sink bricks (source brick was down). shard uses the iatt values from lookup cbk to calculate the size and block count, which in this case were incorrect values. shard_local_t->last_block was thus initialised to -1, resulting in an infinite while loop in shard_common_resolve_shards(). Fix: Use client quorum logic to allow or fail the lookups from afr if there are no readable subvolumes. So in replica-3 or arbiter vols, if there is no good copy or if quorum is not met, fail lookup with ENOTCONN. With this fix, we are also removing support for quorum-reads xlator option. So if quorum is not met, neither read nor write txns are allowed and we fail the fop with ENOTCONN.

* cluster/afr: Fix for arbiter becoming sourcekarthik-us2017-11-184-6/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When eager-lock is on, and two writes happen in parallel on a FD we were observing the following behaviour: - First write fails on one data brick - Since the post-op is not yet happened, the inode refresh will get both the data bricks as readable and set it in the inode context - In flight split brain check see both the data bricks as readable and allows the second write - Second write fails on the other data brick - Now the post-op happens and marks both the data bricks as bad and arbiter will become source for healing Fix: Adding one more variable called write_suvol in inode context and it will have the in memory representation of the writable subvols. Inode refresh will not update this value and its lifetime is pre-op through unlock in the afr transaction. Initially the pre-op will set this value same as read_subvol in inode context and then in the in flight split brain check we will use this value instead of read_subvol. After all the checks we will update the value of this and set the read_subvol same as this to avoid having incorrect value in that.

* geo-rep: Fix data sync issue during hardlink, renameKotresh HR2017-11-141-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The data is not getting synced if master witnessed IO as below. 1. echo "test_data" > f1 2. ln f1 f2 3. mv f2 f3 4. unlink f1 On master, 'f3' exists with data "test_data" but on slave, only f3 exists with zero byte file without backend gfid link. Cause: On master, since 'f2' no longer exists, the hardlink is skipped during processing. Later, on trying to sync rename, since source ('f2') doesn't exist, dst ('f3') is created with same gfid. But in this use case, it succeeds but backend gfid would not have linked as 'f1' exists with the same gfid. So, rsync would fail with ENOENT as backend gfid is not linked with 'f3' and 'f1' is unlinked. Fix: On processing rename, if src doesn't exist on slave, don't blindly create dst with same gfid. The gfid needs to be checked, if it exists, hardlink needs to be created instead of mknod.

| | | | | | | | | | | | | | | | This patch solves a detection problem in configure.ac that prevented that compilation detects builtin __atomic or __sync functions. It also adds more atomic types and support for other atomic functions. An special case has been added to support 64-bit atomics on 32-bit systems. The solution is to fallback to the mutex solution only for 64-bit atomics, but smaller atomic types will still take advantage of builtins if available.

* extras: scripts to control CPU/MEMORY for any gluster daemon during runtimeMohit Agrawal2017-11-134-1/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Sometime gluster daemons like glustershd can consume a lot of cpu and/ or memory if there is a large amount of data/ entries to be healed. Solution: Until we have some form of throttling/ QoS mechanisms built into gluster, we can use control groups for regulating cpu and memory of any gluster daemon using control-cpu-load.sh and control-mem.sh scripts respectively. Test: To test the control-cpu-load.sh script follow below procedure: 1) Setup distribute replica environment 2) Selfheal daemon off 3) Down one node from replica nodes 4) Create millions of files from mount point 5) Start down node 6) Check cpu usage for shd process in top command 7) Run script after provide shd pid with CPU quota value 8) Check again cpu usage for shd process in top command Note: control-mem.sh script can cap the memory usage of the process to the set limit, beyond which the process gets blocked. It resumes either when the memory usage comes down or if the limit is increased. BUG: 1496335 Change-Id: Id73c36b73ca600fa9f7905d84053d1e8633c996f Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
* cluster/afr: Print heal info split-brain output in stream fashionkarthik-us2017-11-131-0/+2
| | | | | | | | | | | | | | | | Problem: When we trigger the heal info split-brain command the o/p is not streamed as it is received, but dumped at the end for all the bricks together. This gives a perception that the command is hung. Fix: When we get a split brain entry while crawling throught the pending heal entries, flush that immediately so that it prints the output in a stream fashion and doesn't look like the cli is hung.

| | | | | | | | | | | | | Issue: pid is written into glusterd.pid by child process instead of parent process while forking. Fix: After fork returns child pid to parent process, it falls under default case of switch statement, call glusterfs_pidfile_update() in default case instead of postfork label.

* cluster/ec: Keep last written strip in in-memory cacheAshish Pandey2017-11-109-84/+525
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider an EC volume with configuration 4 + 2. The stripe size for this would be 512 * 4 = 2048. That means, 2048 bytes of user data stored in one stripe. Let's say 2048 + 512 = 2560 bytes are already written on this volume. 512 Bytes would be in second stripe. Now, if there are sequential writes with offset 2560 and of size 1 Byte, we have to read the whole stripe, encode it with 1 Byte and then again have to write it back. Next, write with offset 2561 and size of 1 Byte will again READ-MODIFY-WRITE the whole stripe. This is causing bad performance because of lots of READ request travelling over the network. There are some tools and scenario's where such kind of load is coming and users are not aware of that. Example: fio and zip Solution: One possible solution to deal with this issue is to keep last stripe in memory. This way, we need not to read it again and we can save READ fop going over the network. Considering the above example, we have to keep last 2048 bytes (maximum) in memory per file.
