Hello
I still have a few problems to sort out with my NetBSD port of glusterfs.
On of them is the strangs stalls I have doing normal operation.
I run glusterfsd -N --debug -L DEBUG on the server side and
glusterfs -N --debug -L DEBUG /mnt on the client side. I can observe
the transactions going back and forth.
When copying a directory, exchanges often stall for a few seconds. If
I attach with gdb to check what the server is doing, I have this:
#0 0xbbada5a7 in _lwp_park () from /lib/libc.so.12
#1 0xbbbae8eb in pthread_cond_timedwait () from /usr/lib/libpthread.so.0
#2 0xbba96062 in posix_janitor_thread_proc (data=0xbb95b060) at posix.c:1404
#3 0xbbbb09df in pthread_create () from /usr/lib/libpthread.so.0
#4 0xbbafc670 in swapcontext () from /lib/libc.so.12
This is this block:
if (list_empty (&priv->janitor_fds)) {
time (&timeout.tv_sec);
timeout.tv_sec += priv->janitor_sleep_duration;
timeout.tv_nsec = 0;
pthread_cond_timedwait (&priv->janitor_cond,
&priv->janitor_lock,
&timeout);
goto unlock;
}
gdb tells me that priv->janitor_sleep_duration is set to 600.
I assume I have a bug to track somewhere, but perhaps a person
knowledgable with glusterfs could give me a good hint.
