Hi Toby, According to the crash log, the cause may be the following: glusterfsd/src/glusterfsd-mgmt.c line 1394 static char oldvolfile[131072]; so if the volume file(/var/lib/glusterd/glustershd/glustershd-server.vol) is larger than 128K then it simply crashes. This happens if there're a lot of

Hi james ! 1) Yes, right now, we run as root. Thanks for noticing :) ... We are working on modifying this in the very near future. The problem is that the plugin attempts to mount a filesystem, but we recently have discussed that auto mount behaviour may be a superfluous feature, since

Hi, We have a set of 4 gluster nodes, all in replicated (design?) We use it to store our qcow2 images for kvm. These images have a variable IO, though most of them are for reading only. I tried to find some documentation re. performance optimization, but it's either unclear to me, or I
