| | | | | | | There were two glfs_init(and friends) invocations per op (create & delete). This patch just unifies those calls (since they anyway belong to same volume) Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
* gluster-block: migrate build to libtoolz and create rpmPrasanna Kumar Kalever2017-02-0724-225/+484
| | | | | | | | | | | | | | | | | | | | | | | | | | Till now we had simple makefile for checking dependencies and building. Using libtoolz will give more control on dependency checks and flexibility. This patch also introduce rpm build feature.

* gluster-blockd: consider spare nodes to satisfy the multipath requestPrasanna Kumar Kalever2017-01-309-79/+229
| | | | | | | | | | | In case if number of block hosts are more than the multipath request, consider that spare nodes to satify the request. Lets say we need multipath of 3, but the admin provides 5 block-hosts. If any of the node fail to configure target from first three, then consider configuring fourth node to satify the HA request.

* gluster-blockd: implement transaction frameworkPrasanna Kumar Kalever2017-01-309-52/+422
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduce the transaction locking also, start maintaining meta data journaling per block Every request is follows transaction, at the start of any transaction we take blocking lock on "/block-meta/meta.lock" file and at the end we unlock. Meanwhile while, when the transaction is in progress we do journaling, while performing series of operations, used for future purposes and roll backing. A sample journal file looks like: $ cat /mnt/block-meta/LUN1 GBID: xyz-abc SIZE : 5GiB HA: 3 ENTRYCREATE: INPROGRESS ENTRYCREATE: SUCCESS NODE1: INPROGRESS NODE2: INPROGRESS NODE3: INPROGRESS NODE2: SUCCESS NODE3: FAIL NODE1: SUCCESS NODE4: INPROGRESS NODE4: SUCCESS NODE3: CLEANUPSUCCESS <EOF> Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from now We basically have 2 RPC connections, 1. Between gluster block CLI and local gluster-blockd This connection is basically UNIX/local netid ,listening on /var/run/gluster-blockd.socket file. The CLI always Send/Receive the commands to/from the local gluster-blockd via local rpc. 2. Between gluster-blockd's, i.e local (to cli) gluster-blockd and the gluster-blockd's running on remote(blockhost) This is the tcp connection. The rpc requests are listening on 24006 Also from now gluster-blockd is multi threaded (As of now 2 threads) Lets consider the Create Request to understand what each thread solves Thread1 (THE CLI THREAD) * Listening on local RPC * Generate the GBID (UUID) and create the entry with name GBID in the given volume with a requested size. * And Send the Configuration requests to remote hosts, waits for the replies (HINt: after this point Read Thread2 and come back) * Return to CLI. Thread 2 (THE SERVER THREAD) * Listens on 24006 * On Receiving an event, read the structure. * Executes the required "targetcli bla bla bla" command locally * Fills the command exitcode and the output in the RPC reply structure and send reply Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>

* gluster-blockd: daemonize the utilityPrasanna Kumar Kalever2017-01-1612-482/+328
| | | | | | | | | | | | | | | | | this patch, deprecate ssh way of communicating between server nodes/pods Reason: ssh way is hard to be accepted in container world (Kube). An another option kubeExec way seems to be a bit weird, to have uniform way of communication in container and non container worlds, we prefer RPC. From now we communicate via RPC, using a static port 24009 Hence, we have two components, server component -> gluster-blockd (daemon) client component -> gluster-block (cli) Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>

* gluster-block: Initial CommitPrasanna Kumar Kalever2016-12-239-0/+1533
gluster block storage CLI. As of now, gluster-block is capable of creating tcmu based gluster block devices, across multiple nodes. All you need is a gluster volume (on one set of nodes) and tcmu-runner (https://github.com/open-iscsi/tcmu-runner) running on same(as gluster) or different set of nodes. From an another (or same) node where gluster-block is installed you can create iSCSI based gluster block devices. What it can do ? -------------- 1. create a file (name uuid) in the gluster volume. 2. create the iSCSI LUN and export the target via tcmu-runner in multiple nodes (--block-host IP1,IP2 ...) 3. list the available LUN's across multiple nodes. 4. get info about a LUN across multiple nodes. 5. delete a given LUN across all given nodes. $ gluster-block --help gluster-block (Version 0.1) -c, --create <name> Create the gluster block -v, --volume <vol> gluster volume name -h, --host <gluster-node> node addr from gluster pool -s, --size <size> block storage size in KiB|MiB|GiB|TiB.. -l, --list List available gluster blocks -i, --info <name> Details about gluster block -m, --modify <RESIZE|AUTH> Modify the metadata -d, --delete <name> Delete the gluster block [-b, --block-host <IP1,IP2,IP3...>] block servers, clubbed with any option Typically gluster-block, gluster volume and tcmu-runner can coexist on single set of nodes/node or can be split across different set of nodes. Install: ------- $ make -j install (hopefully that should correct you.) Points to remember: ------------------ 1. setup gluster volume 2. run tcmu-runner service Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
