* cli: logging improvementsVijay Bellur2015-05-253-5/+5
| | | | | | | | | | | | | | | | | | | | | | | 1. cli used to log messages at all log levels. This is related to a peculiar behavior of gcc which treats any enum variable whose type has non-negative only defined values to be an unsigned integer. This would cause cli's loglevel (defaulted from state->loglevel) to be set as (uint)-1 previously and hence all log messages across levels would appear in the cli log file. Now cli's loglevel defaults to log level INFO. 2. Changed logging level of messages of type "Returning %d".. to DEBUG.

The former is substituted as an empty string, leading to possible failures depending of the user shell tolerance. NetBSD's /bin/sh seems to choke more easily than Linux's /bin/bash, but if the later does not fail, it does not created the intended directories anyway.

* glusterd : release cluster wide locks in op-sm during failuresAtin Mukherjee2015-03-031-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterd op-sm infrastructure has some loophole in handing error cases in locking/unlocking phases which ends up having stale locks restricting further transactions to go through. This patch still doesn't handle all possible unlocking error cases as the framework neither has retry mechanism nor the lock timeout. For eg - if unlocking fails in one of the peer, cluster wide lock is not released and further transaction can not be made until and unless originator node/the node where unlocking failed is restarted. Following test cases were executed (with the help of gdb) after applying this patch: * RPC timesout in lock cbk * Decoding of RPC response in lock cbk fails * RPC response is received from unknown peer in lock cbk * Setting peerinfo in dictionary fails while sending lock request for first peer in the list * Setting peerinfo in dictionary fails while sending lock request for other peers * Lock RPC could not be sent for peers For all above test cases the success criteria is not to have any stale locks Patch link : http://review.gluster.org/9012 Change-Id: Ia1550341c31005c7850ee1b2697161c9ca04b01a BUG: 1179136 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/9012 Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/9393 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com>

The options are corrupted when memory is reallocated, which sometimes leads to a crashes on NetBSD when socket_connect() attempted to read options. Fix the problem by not doing the dict_unref().

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new options have been added to the 'create' command of the cli interface: disperse [<count>] redundancy <count> Both are optional. A dispersed volume is created by specifying, at least, one of them. If 'disperse' is missing or it's present but '<count>' does not, the number of bricks enumerated in the command line is taken as the disperse count. If 'redundancy' is missing, the lowest optimal value is assumed. A configuration is considered optimal (for most workloads) when the disperse count - redundancy count is a power of 2. If the resulting redundancy is 1, the volume is created normally, but if it's greater than 1, a warning is shown to the user and he/she must answer yes/no to continue volume creation. If there isn't any optimal value for the given number of bricks, a warning is also shown and, if the user accepts, a redundancy of 1 is used. If 'redundancy' is specified and the resulting volume is not optimal, another warning is shown to the user. A distributed-disperse volume can be created using a number of bricks multiple of the disperse count.

* socket/glusterd/client: enable SSL for managementJeff Darcy2014-07-101-4/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The feature is controlled by presence of the following file: /var/lib/glusterd/secure-access See the comment near the definition of SECURE_ACCESS_FILE in glusterfs.h for the rationale. With this enabled, the following rules apply to connections: UNIX-domain sockets never have SSL. Management-port sockets (both connecting and accepting, in daemons and CLI) have SSL based on presence of the file. Other IP sockets have SSL based on the existing client.ssl and server.ssl volume options. Transport multi-threading is explicitly turned off in glusterd (it would otherwise be turned on when SSL is) due to multi-threading issues. Tests have been elided to avoid risk of leaving a file which will cause all subsequent tests to run with management SSL still enabled. IMPLEMENTATION NOTE The implementation is a bit messy, and consists of two stages. First we decide whether to set the relevant fields in our context structure, based on presence of the sentinel file OR a command-line override. Later we decide whether a particular connection should actually use SSL, based on the context flags plus what kind of connection we're making[1] and what kind of daemon we're in[2]. [1] inbound, outbound to glusterd port, other outbound [2] glusterd, glusterfsd, other TESTING NOTE Instead of just running one special test for this feature, the ideal would be to run all tests with management SSL enabled. However, it would be inappropriate or premature to set up an optional feature in the patch itself. Therefore, the method of choice is to submit a separate patch on top, which modifies "cleanup" in include.rc to recreate the secure-access file and associated SSL certificate/key files before each test.

Syntax : gluster snapshot config auto-delete <enable/disable> DETAILS : 1) When auto-delete feature is disabled, If the the soft-limit is reached then user is given a warning about exceeding soft-limit along with successful snapshot creation message (oldest snapshot is not deleted). And upon reaching hard-limit further snapshot creation is not allowed. Example : ------------------------------------------------------------------ |Case - 1: Upon reaching soft-limit | |Snapshot create : snap successfully created. |Warning : soft-limit of volume (vol) is reached. Snapshot creation |is not possible once hard-limit is reached. | |----------------------------------------------------- |Case - 2: Upon reaching hard-limit | |Snapshot create : snap creation failed. |Error : hard-limit of volume (vol) is reached, Hence it is not |possible to take further snapshots. Please delete few snapshots |of the volume (vol) before taking another snapshot. ------------------------------------------------------------------ 2) When auto-delete feature is enabled, then as soon as the soft-limit is reached the oldest snapshot is deleted for every successful snapshot creation (same as existing method), With this it is made sure that number of snapshot created is not more than snap-max-hard-limit.

| | | | | | | | | | | | | | | | | | | | | | | | While creating a volume and adding a brick validation for _POSIX_PATH_MAX is done on absolute pathname instead of relative pathname due to which a brickpath having less than _POSIX_PATH_MAX may also fail the validation if the directory length is greater than (_POSIX_PATH_MAX -strlen(brickpath/volume name). Also this fix addresses one cli response message correction which says the volume file is too long instead of brick path is too long (when brickpath length validation doesn't fail and vol file length validation fails.) It is also important to note that with the current design of volfile naming, it can not be guranteed that volname and brickpath can have max of _POSIX_PATH_MAX characters.
