Description of problem: Recently, a GlusterFS SysAdmin was attempting to update host definitions in his GlusterFS cluster files, but was having trouble due to the uninformative log error message when he made a minor mistake. The log error messages he was seeing were: [2014-01-07 03:08:53.810098] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-0 [2014-01-07 03:08:53.810122] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-1 [2014-01-07 03:08:53.810132] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-2 [2014-01-07 03:08:53.810141] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-3 [2014-01-07 03:08:53.810149] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-4 [2014-01-07 03:08:53.810158] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-5 [2014-01-07 03:08:53.810167] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-6 [2014-01-07 03:08:53.810175] E [glusterd-store.c:1858:glusterd_store_retrieve_volume] 0-: Unknown key: brick-7 [2014-01-07 03:08:54.201857] E [glusterd-store.c:2487:glusterd_resolve_all_bricks] 0-glusterd: resolve brick failed in restore In this particular instance, he may have missed updating a host definition correctly on a host. To resolve the problem, the SysAdmin was able to revert his cluster configuration to the previous state (and will try again later). We could probably improve the log error message to be more informative, so problems like this are easier to diagnose and/or resolve. A suggested better error string from the SysAdmin is: [2014-01-07 xx:xx:xx.xxxxxx] E [glusterd-store.c:xxxx:glusterd_store_retrieve_volume] 0-: The brick filename specified in file "/path.../filename" does not exist in the brick directory "/path/..." This is likely an easy code change to make. :) Version-Release number of selected component (if applicable): 3.4.1 Additional info: http://supercolony.gluster.org/pipermail/gluster-users/2014-January/038501.html
