Good morning, we currently transfer some data to a new glusterfs volume; to check the throughput of the new volume/setup while the transfer is running i decided to create some files on one of the gluster servers with dd in loop: while true; do dd if=/dev/urandom of=/shared/private/1G.file bs=1M count=1024; rm /shared/private/1G.file; done /shared/private is the mount point of the glusterfs volume. The dd should run for about an hour. But now it happened twice that during this loop the transport endpoint gets disconnected: dd: failed to open '/shared/private/1G.file': Transport endpoint is not connected rm: cannot remove '/shared/private/1G.file': Transport endpoint is not connected In the /var/log/glusterfs/shared-private.log i see: [2019-01-24 07:03:28.938745] W [MSGID: 108001] [afr-transaction.c:1062:afr_handle_quorum] 0-persistent-replicate-0: 7212652e-c437-426c-a0a9-a47f5972fffe: Failing WRITE as quorum i s not met [Transport endpoint is not connected] [2019-01-24 07:03:28.939280] E [mem-pool.c:331:__gf_free] (-->/usr/lib/x86_64-linux-gnu/glusterfs/5.3/xlator/cluster/replicate.so(+0x5be8c) [0x7eff84248e8c] -->/usr/lib/x86_64-lin ux-gnu/glusterfs/5.3/xlator/cluster/replicate.so(+0x5be18) [0x7eff84248e18] -->/usr/lib/x86_64-linux-gnu/libglusterfs.so.0(__gf_free+0xf6) [0x7eff8a9485a6] ) 0-: Assertion failed: GF_MEM_TRAILER_MAGIC == *(uint32_t *)((char *)free_ptr + header->size) [----snip----] The whole output can be found here: https://pastebin.com/qTMmFxx0 gluster volume info here: https://pastebin.com/ENTWZ7j3 After umount + mount the transport endpoint is connected again - until the next disconnect. A /core file gets generated. Maybe someone wants to have a look at this file? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx https://lists.gluster.org/mailman/listinfo/gluster-users
