Hi folks! I'm trying to get rid of any dependency on libgcc*, but without success so far. The following commands were executed on a freshliy installed and updated Ubuntu 16.04 LTS: === snip === sudo apt-get install build-essential libffi-dev cmake # see aptget.txt for packages installed sudo mv /usr/local /usr/local.orig git clone https://github.com/llvm/llvm-project.git cd llvm-project; git

Hi, I switched from "configure and make" to "cmake" build-system and wanted to speedup my build. In my build-script I use...

I am fighting this issue: Bug 1540376 ? Tiered volume performance degrades badly after a volume stop/start or system restart. https://bugzilla.redhat.com/show_bug.cgi?id=1540376 Does anyone have any ideas on what might be causing this, and what a fix or work-around might be?

Hi All, I am trying to build the 'lld' linker on Mac OS 10.9, but during the build, I am getting the errors. Following are the steps that I have followed: 1.     I have downloaded the ‘llvm-stable’ source code from the following location:   https://github.com/llvm-mirror/llvm/tree/stable   2.     Machine details(on which llvm source code isbeing built) are as follows: $ sw_vers

Tested it in two different environments lately with exactly same results. Was trying to get better read performance from local mounts with hundreds of thousands maildir email files by using SSD, hoping that .gluster file stat read will improve which does migrate to hot tire. After seeing what you described for 24 hours and confirming all move around on the tires is done - killed it. Here are my volume setting...

...resent, albeit empty since I don't have cluster.write-freq- threshold nor cluster.read-freq-threshold set, so features.record-counters is off and nothing should be going into the DB. I've found that if I delete these .db files after the volume stop, but before the volume start, the tiering performance is normal, not degraded. Of course all of the history in these DB files is lost. Not sure what other ramifications there are to deleting these .db files. When I did have one of the freq-threshold settings set, I did see a record get added to the file, so the sqlite3 DB is working to some degree....

...all, I have a gluster volume used to host several VMs (managed through oVirt). The volume is a replica 3 with arbiter and the 3 servers use 1 Gbit network for the storage. When testing with dd (dd if=/dev/zero of=testfile bs=1G count=1 oflag=direct) out of the volume (e.g. writing at /root/) the performance of the dd is reported to be ~ 700MB/s, which is quite decent. When testing the dd on the gluster volume I get ~ 43 MB/s which way lower from the previous. When testing with dd the gluster volume, the network traffic was not exceeding 450 Mbps on the network interface. I would expect to reach near 9...

Perhaps that's because the 3rd node that wasn't accessible from the client before was the arbiter node?
