Hello all, So, another day another issue. I was trying to play with quotas on my volume: ================================================================================ [root@stor104 ~]# gluster volume status Status of volume: live Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick stor104:/zfs/brick0/brick 49167 Y 13446 Brick stor104:/zfs/brick1/brick 49168 Y 13457 Brick stor104:/zfs/brick2/brick 49169 Y 13468 Brick stor106:/zfs/brick0/brick 49159 Y 14158 Brick stor106:/zfs/brick1/brick 49160 Y 14169 Brick stor106:/zfs/brick2/brick 49161 Y 14180 NFS Server on localhost 2049 Y 13483 Quota Daemon on localhost N/A Y 13490 NFS Server on stor106 2049 Y 14195 Quota Daemon on stor106 N/A Y 14202 Task Status of Volume live ------------------------------------------------------------------------------ Task : Rebalance ID : 6bd03709-1f48-49a9-a215-d0a6e6f3ab1e Status : completed ================================================================================ Not sure if the "Quota Daemon on localhost -> N/A" is normal, but that's another topic. While the quotas were enabled, I did some test copying a whole tree of small files (the Linux kernel sources) to the volume to see which performance I would get, and it was really low. So I decided to disable quotas again: ================================================================================ [root@stor104 ~]# gluster volume status Status of volume: live Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick stor104:/zfs/brick0/brick 49167 Y 13754 Brick stor104:/zfs/brick1/brick 49168 Y 13765 Brick stor104:/zfs/brick2/brick 49169 Y 13776 Brick stor106:/zfs/brick0/brick 49159 Y 14282 Brick stor106:/zfs/brick1/brick 49160 Y 14293 Brick stor106:/zfs/brick2/brick 49161 Y 14304 NFS Server on localhost 2049 Y 13790 NFS Server on stor106 2049 Y 14319 Task Status of Volume live ------------------------------------------------------------------------------ Task : Rebalance ID : 6bd03709-1f48-49a9-a215-d0a6e6f3ab1e Status : completed ================================================================================ I remounted the volume from the client and tried deleting the directory containing the sources, which gave me a very long list of this: ================================================================================ rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/testing/selftests/ftrace/test.d/kprobe’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/testing/selftests/ptrace’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/testing/selftests/rcutorture/configs/rcu/v0.0’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/testing/selftests/rcutorture/configs/rcu/v3.5’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/testing/selftests/powerpc’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/perf/scripts/python/Perf-Trace-Util’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/perf/Documentation’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/perf/ui/tui’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/perf/util/include’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/lib’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/tools/virtio’: Directory not empty rm: cannot remove ‘/glusterfs/live/linux-3.18.7/virt/kvm’: Directory not empty ================================================================================ I did my homework on Google, yet the information I found was that the cause for this is that the contents of the bricks have been modified locally. It's definitely not the case here, I have *not* touched the contents of the bricks. So my question is: is it possible that disabling the quotas may have had some side effects on the metadata of Gluster? If so, what can I do to force Gluster to rescan all local directories and "import" local files?
