* | | nsr-recon: fix entry-count error when logs are preallocatedJeff Darcy2014-02-111-12/+65

* | | 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.

| * cluster/dht: goto statements may cause loop exit before memory is freed.Christopher R. Hertel2014-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Memory is allocated at the top of the while loop via a call to gf_strdup(), but there are several goto calls that exit the loop, and the memory is not freed before each of those calls to goto. This fix moves the final call to GF_FREE() higher in the loop so that the memory is correctly freed. Two variables, dup_str and str_tmp1, point to portions of the allocated memory. Neither are used past the final call to GF_FREE( dup_str ). BUG: 789278 CID: 1124780 Change-Id: Id24b80cdbfd8b8855c80fffec63d7fce98cbed4a Signed-off-by: Christopher R.

Detailed explanation of the Root cause: We found the bug in 'gf_defrag_migrate_data' in rebalance operation: Lets look at interesting parts of the function: int gf_defrag_migrate_data (xlator_t *this, gf_defrag_info_t *defrag, loc_t *loc, dict_t *migrate_data) { ..... code section - [ Loop ] while ((ret = syncop_readdirp (this, fd, 131072, offset, NULL, &entries)) != 0) { ..... code section - [ ERRNO-1 ] (errno of readdirp is stored in readdir_operrno by a thread) /* Need to keep track of ENOENT errno, that means, there is no need to send more readdirp() */ readdir_operrno = errno; ..... code section - [ SYNCOP-1 ] (syncop_getxattr is called by a thread) ret = syncop_getxattr (this, &entry_loc, &dict, GF_XATTR_LINKINFO_KEY); code section - [ ERRNO-2] (checking for failures of syncop_getxattr(). This may not always be executed in same thread which executed [SYNCOP-1]) if (ret < 0) { if (errno != ENODATA) { loglevel = GF_LOG_ERROR; defrag->total_failures += 1; ..... } the function above could be executed by thread(t1) till [SYNCOP-1] and code from [ERRNO-2] can be executed by a different thread(t2) because of the way syncop-infra schedules the tasks. when the code is compiled with -O2 optimization this is the assembly code that is generated: [ERRNO-1] 1165 readdir_operrno = errno; <<---- errno gets expanded as *(__errno_location()) 0x00007fd149d48b60 <+496>: callq 0x7fd149d410c0 <address@hidden> 0x00007fd149d48b72 <+514>: mov %rax,0x50(%rsp) <<------ Address returned by __errno_location() is stored in a special location in stack for later use. 0x00007fd149d48b77 <+519>: mov (%rax),%eax 0x00007fd149d48b79 <+521>: mov %eax,0x78(%rsp) .... [ERRNO-2] 1281 if (errno != ENODATA) { 0x00007fd149d492ae <+2366>: mov 0x50(%rsp),%rax <<----- Because it already stored the address returned by __errno_location(), it just dereferences the address to get the errno value.

So [ERRNO-2] ends up reading errno of t1 instead of errno of t2 even though t2 is executing [ERRNO-2] code section. When code is compiled without any optimization for [ERRNO-2]: 1281 if (errno != ENODATA) { 0x00007fd58e7a326f <+2237>: callq 0x7fd58e797300 <address@hidden><<--- As it is calling __errno_location() again it gets the location from t2 so it works as intended. 0x00007fd58e7a3274 <+2242>: mov (%rax),%eax 0x00007fd58e7a3276 <+2244>: cmp $0x3d,%eax 0x00007fd58e7a3279 <+2247>: je 0x7fd58e7a32a1 <gf_defrag_migrate_data+2287> Fix: Make syncop_xxx() return (-errno) value as the return value in case of errors and all the functions which make syncop_xxx() will need to use (-ret) to figure out the reason for failure in case of syncop_xxx() failures.

This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.

The second client meanwhile bails out of afr_lookup_perform_self_heal() because afr_is_transaction_running() returns true due to the lock obtained by client-1. Consequetly in client-2, "sh-failed" does not get set in the dict, causing quick-read translator to *not* invalidate the inode, thereby serving data randomly from one of the bricks.

| * cluster/dht: Make sure gf_defrag_migrate_data is not optimizedPranith Kumar K2013-12-111-0/+7
