But those logs are from a default > installation. Yepo me too, I did alot of the qualification for multi threaded epoll and that is what I found to best saturate my back end(12 disk RAID 6 spinners) without wasting threads. Be careful tuning this up too high if you have alot of bricks per server, you could run into some contention with all of those threads fighting for CPU time. On the hooks stuff on my system I have: -rwxr-xr-x. 1 root root 1459 Jun 1 06:35 S29CTDB-teardown.sh -rwxr-xr-x. 1 root root 1736 Jun 1 06:35 S30samba-stop.sh Do you have SMB installed on these systems? IIRC the scripts are only run if the service is chkconfigged on, if you don't have SMB installed and chkconfiged on I don't think these are the problem. -b > > On Sun, Sep 3, 2017 at 9:52 PM, Ben Turner <bturner@xxxxxxxxxx> wrote: > > ----- Original Message ----- > >> From: "Ben Turner" <bturner@xxxxxxxxxx> > >> To: "Serkan Çoban" <cobanserkan@xxxxxxxxx> > >> Cc: "Gluster Users" <gluster-users@xxxxxxxxxxx> > >> Sent: Sunday, September 3, 2017 2:30:31 PM > >> Subject: Re: Glusterd proccess hangs on reboot > >> > >> ----- Original Message ----- > >> > From: "Milind Changire" <mchangir@xxxxxxxxxx> > >> > To: "Serkan Çoban" <cobanserkan@xxxxxxxxx> > >> > Cc: "Gluster Users" <gluster-users@xxxxxxxxxxx> > >> > Sent: Saturday, September 2, 2017 11:44:40 PM > >> > Subject: Re: Glusterd proccess hangs on reboot > >> > > >> > No worries Serkan, > >> > You can continue to use your 40 node clusters. > >> > > >> > The backtrace has resolved the function names and it should be > >> > sufficient > >> > to > >> > debug the issue. > >> > Thanks for letting us know. > >> > > >> > We'll post on this thread again to notify you about the findings. > >> > >> One of the things I find interesting is seeing: > >> > >> #1 0x00007f928450099b in hooks_worker () from > >> > >> The "hooks" scripts are usually shell scripts that get run when volumes > >> are > >> started / stopped / etc. It may be worth looking into what hooks scripts > >> are getting run at shutdown and think about how one of them could hang up > >> the system.
