| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - gluster vol geo-rep M S conf checkpoint <LABEL|now> sets a checkpoint with LABEL (the keyword "now" is special, it's rendered to the label "as of <timestamp of current time>") that's used to refer to the checkpoint in the sequel. (Technically, gsyncd makes a note of the xtime of master's root as of setting the checkpoint, called the "checkpoint target".) - gluster vol geo-rep M S conf \!checkpoint deletes the checkpoint. - gluster vol geo-rep M S stat if status is OK, and there is a checkpoint configured, the checkpoint info is appended to status (either "not yet reached", or "completed at <timestamp of completion>"). (Technically, the worker runs a thread that monitors / serializes / verifies checkpoint status, and answers checkpoint status requests through a UNIX socket; monitoring boils down to querying the xtime of slave's root and comparing with the target.) - gluster vol geo-rep M S conf log-file | xargs grep checkpoint displays the checkpoint history. Set, delete and completion events are logged properly.

* glusterd: generate node UUID lazilyAnand Avati2012-06-071-15/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. This patch is for the 'prevention' of the issue. The approach here is to avoid generating a UUID on the first start of glusterd, but instead generate a node UUID only when a node UUID is found to be necessary. This naturally avoids the creation of node UUID on first boot and prevents the issue to a large extent. This issue also needs a 'cure' patch, which gives more meaningful error messages to the user and provides CLI to recover from the situations (gluster peer reset?)

E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.

Even if we solved this issue, glusterd security settings are too coarse, so that if we made it possible for an unprivileged gsyncd to operate, we would open up too far.

* glusterd / cli: mount-broker serviceCsaba Henk2011-09-121-0/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mountbroker is configured in glusterd volfile through a DSL which is restriced enough to be able to appear in the role of the value of a volfile knob. Basically the DSL describes set-theorical requirements against the option set which is sent by the cli (in the hope of getting a mount with these options). If the requirements meet and the volume id and the uid who is to "own" the mount can be unambigously deduced from the given request, glusterd does the mount with the given parameters. The use case of geo-replication is sugared by means of volume options which then generate a complete mount-broker option set. Demo: - add the following option to your glusterd volfile: option mountbroker-root /tmp/mbr option mountbroker.fool EQL(volfile-id=pop*|user-map-root=*|volfile-server=localhost)&MEET(user-map-root=john|user-map-root=jane) - before starting glusterd, create /tmp/mbr owned by root with mode 0755 - with cli, do $ gluster system:: mount fool volfile-id=pop33 user-map-root=jane volfile-server=localhost - on succesful completion (volume pop33 exists and is started, jane is a valid username), the mount path will be echoed to you - you can get rid of the mount by $ gluster system:: umount <mount-path> Change-Id: I629cf64add0a45500d05becc3316f67cdb5b42ff BUG: 3482 Reviewed-on: http://review.gluster.com/128 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
