| * nsr: use different etcd keys for each NSR subvolumeJeff Darcy2014-03-254-18/+52
| | | | | | | | | | | | | | | | This is necessary both for separate volumes using NSR and for DHT volumes composed of multiple NSR subvolumes. Change-Id: Ia269d70b535cc26900f8b6e7f22706087746fbe7 Signed-off-by: Jeff Darcy <jdarcy@redhat.com>

* nsr: change leader-election code to use new etcd_lockJeff Darcy2014-03-052-182/+69
| | | | | | | | | This is certainy much simpler (therefore easier to maintain) and should be more robust as well. Tested with both real and simulated versions of the etcd API. Change-Id: Ic67de7f87455fcd9aeb1354714698f9562b7e4a7 Signed-off-by: Jeff Darcy <jdarcy@redhat.com>
* nsr: update to latest versions of etcd and etcd-apiJeff Darcy2014-03-053-58/+282
| | | | | | | | Also fixed some general bit-rot around how daemons are started when using real etcd. Change-Id: Ib5d9c8d49982c4562b6a28b7a7c1dd1e5d9d3077 Signed-off-by: Jeff Darcy <jdarcy@redhat.com>
* nsr: add mem_acct_init functionsJeff Darcy2014-03-041-0/+19
| | | | | | | | | | | | It's not clear why this started failing after the last merge, since the mem_acct code hasn't changed for a while, but it did and having those functions is good form anyway. Also removed a bunch of GF_ASSERT(0) calls that made (and will continue to make) debugging unnecessarily painful.

* changes to NSR reconciliation code to add error handling.Raghavan P2014-03-031-3/+40

* nsr : Changes made in nsr logging functionsAnuradha2014-02-171-3/+3
| | | | | | | | | | | | | 1) File pointers for worker and driver logs are now in their respective ctx, instead of static file pointer in nsr logging functions. 2) File pointer for recon-main-log now in nsr_recon_private_t, instead of a static file pointer in nsr recon logging function. 3) Changed a few fprintf to gflog.

* | nsr: add first reconciliation testJeff Darcy2014-02-113-3/+3
|/ | | | | | | | | | | | | | | The test itself fails, because reconciliation never actually seems to complete. Instead, it fills up several log files with 16M lines worth of junk, even though we only did ~200 writes. Fencing is also disabled so we can make progress despite this. Still, this test should provide a basic framework for testing reconciliation once it's fixed. This patch also fixes the hard-coded executable path used to start the recon daemon. Without this, starting the brick fails on a standard install (because the hard-coded path was to a non-standard location).

* | etcd-sim: fix stdio-buffering problemJeff Darcy2014-01-291-38/+68
|/ | | | | | | | | | | | | | Leader election was not working because processes were continuing to read their own cached copies of the data file contents, not seeing each others' changes. Fflush is not sufficient to ensure that data propagates from one process to another. Even ensuring that it gets to disk requires an fsync as well (which we weren't doing). The only viable solution is to *reopen* the data file with an empty buffer. This also makes it easier to ensure correct locking across the whole file, instead of just from the previous seek position to EOF.

* NSR reconciliation: Adding index for each opRaghavan P2014-01-235-2/+17
| | | | | | | We need to have the leader generate an index number for each changelog entry. Change-Id: If451dc00a21dbc481771b713ac75fd0af6887014 Signed-off-by: Raghavan P <rpichai@redhat.com>
* Fix write-queuing logic.Jeff Darcy2014-01-221-5/+8
| | | | | | | | | | The write path for followers would call STACK_WIND without incrementing ictx->active first. Therefore, when we got to nsr_writev_complete, we'd decrement from zero (overflow). That write would succeed, but then the next would see ictx->active was set and queue instead of executing.

* cluster/nsr-server: fix etcd-sim date handlingJeff Darcy2014-01-221-66/+59
| | | | | | | | | | | There was just no particularly good reason to be doing all of those conversions for comparison on the same machine, and it was actually causing failures on a test machine where strptime was sporadically creating a structure where the "hours" field was off by one. Also added missing functions to allow unit testing, fixed some headers and indentation, etc. Change-Id: I3b1a80365d72bdb5afb0119a8e6505e2bc47a94f Signed-off-by: Jeff Darcy <jdarcy@redhat.com>
* nsr : Fix "special" recon logging functions.Anuradha2014-01-212-2/+43
| | | | | | | | | | | | | | | | | | | | | Combining two patches together. http://review.gluster.org/#/c/6538/4, author : Jeff Darcy and http://review.gluster.org/#/c/6748/2, author : Anuradha Talur. (1) Put logs into /var/log instead of /tmp. (2) Added debug-level check. (3) Added function/line information. (4) Fixed many instances of missing symbol GF_LOG_ERR. Removing spurious newlines will have to wait until a subsequent patch. Keeping this one up to date is tedious enough. Changed the logging directory of reconciliation logs to /var/log/nsr-logs.
