[Gluster-users] Glusterd proccess hangs on reboot

[Serkan Çoban]

Same thing happens with 3.12.rc0. This time perf top shows hanging in
libglusterfs.so and below is the glusterd logs, which are different
from 3.10.
With 3.10.5, after 60-70 minutes CPU usage becomes normal and we see
brick processes come online and system starts to answer commands like
"gluster peer status"..
