* gluster-block: use targetcli interactive modePrasanna Kumar Kalever2017-08-281-1/+51
| | | | | | | | | | | | | | | | | | Currently, on each targetcli create call, rtslib will rebuild its bs_cache, so as the /sys/kernel/config/target/core dir gets more entries this takes longer and longer to scan. Hence using repetitive targetcli in the block create for creating iqn, backend, setting acls, setting globals will induce too much delay in block create. As the number of blocks on the node increases, the delay will be too longer. This does not happen if we open targetcli in interactive mode and just do multiple create commands form it, since the bs_cache is build once.

* cache: implement LRU cache to hold glfs objectsPrasanna Kumar Kalever2017-06-052-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: ------- 1. Currently, each cli command take ~5 secs for execution. The Maximum latency is due to initializing a glfs object (glfs_init() and friends). 2. OOM kills due to glfs_fini() leaks (~10MB per object) Solution: -------- Caching bipasses glfs_init() calls from the very next command, as in the first command it goes via the glfs_init route, since there will be cache miss. Hence with caching cli command on a local machine should take ~1 sec. ATM, the cache query looks at the volume name only, as the host name will be localhost in our case and transport will be tcp 24007 always. The default cache capacity is 5 i.e there can be a max of five glfs entries in the cache, anything more will lead to release of least recently used object. This way, if there are <= 5 volume in use for block, there will be no glfs_fini() calls, hence no leaks, no OOM's. The next patch will help in making cache capacity configurable.

* build: use rpcgen to generate all XDR codeNiels de Vos2017-03-172-3/+5
| | | | | | | | | | | | | | | | | | | | | Remove all generated files and have them generated when needed. This build a libgbrpcxdr.la archive with the .o files that gets linked into the libgbrpc.la archive. 'rpcgen' generates .c code that triggers warnings for various compilers. This is not something that can easily be fixed, so add rpc-pragmas.h (like GlusterFS does) to prevent these warnings. There are some functions used by gluster-blockd.c that are not part of the header and were manually added to block.h. Because block.h get regenerated now, these functions have been added to a new file block_svc.h. Note that generated and compiled files land in $(top_builddir). This directory does not need to be the same as $(top_srcdir). Change-Id: I0e764d159d6d785699537eed4e24b16883218038 Fixes: #2 Signed-off-by: Niels de Vos <ndevos@redhat.com>
* lockfile: don't allow multiple instances of daemon to runPrasanna Kumar Kalever2017-02-211-6/+36
| | | | | | | | | | | | | | until now there is no check to defend on multiple runs of daemon within the same node. This patch takes a non blocking lock on 'gluster-blockd.lock' file, if it succeeds only then daemon is allowed to run, if there is already a lock on lock-file (taken by some other instance of gluster-blockd) we will exit. This patch also renames GB_UNIX_ADDRESS from gluster-block.socket to gluster-blockd.socket, as that makes better sense.
