      Ran into this issue too with 4.1.5 with an arbiter
        setup.  Also could not run a statedump due to "Segmentation
        fault".
        

        Tried with 3.12.13 and had issues with locked
          files as well.  We were able to do a statedump and found that
          some of our files were "BLOCKED"
          (xlator.features.locks.vol-locks.inode).  Attached part of
          statedump.
        

        Also tried clearing the locks using clear-locks,
          which did remove the lock, but as soon as I tried to cat the
          file, it got locked again and the cat process hung.
      
    
    I created issue in bugzilla, can't find it though :-(

    Looks like there is no activity after I sent all logs...

                    Hello!

                      
                      Yesterday we hit something like this on 4.1.2

                      
                      Centos 7.5.

                      
                      Volume is replicated - two bricks and one arbiter.

                      
                      We rebooted arbiter, waited for heal end,  and
                      tried to live migrate VM to another node ( we run
                      VMs on gluster nodes ):

                      [server-helpers.c:286:do_fd_cleanup]
                      0-pool-server: fd cleanup on /balamak.img

                      
                      after this I/O on  /balamak.img was blocked.

                      
                      Only solution we found was to reboot all 3 nodes.

                      
                      Is there any bug report in bugzilla we can add
                      logs?

                      
                    Not aware of such bugs!
                     
                     Is it possible to
                      turn of these locks?

                      
                    Not sure, will get back on this one!
                  
                
            btw, found this link

            https://docs.gluster.org/en/v3/Troubleshooting/troubleshooting-filelocks/

            
            tried on another (test) cluster:

            
             [root@marduk ~]# gluster volume statedump pool

            Segmentation fault (core dumped)

             
            4.1.2 too...

            
            something is wrong here.

            
                     Thank you!
