Hi, I've got this strange problem where a striped endpoint will crash when I try to use cp to copy files off of it but not when I use rsync to copy files off: [user at gluster5 user]$ cp -r Python-2.6.4/ ~/tmp/ cp: reading `Python-2.6.4/Lib/lib2to3/tests/data/fixers/myfixes/__init__.py': Software caused connection abort cp: closing `Python-2.6.4/Lib/lib2to3/tests/data/fixers/myfixes/__init__.py': Transport endpoint is not connected pending frames: frame : type(1) op(READ) frame : type(1) op(READ) patchset: 2.0.1-886-g8379edd signal received: 11 time of crash: 2010-03-02 11:06:40 configuration details: argp 1 backtrace 1 dlfcn 1 fdatasync 1 libpthread 1 llistxattr 1 setfsid 1 spinlock 1 epoll.h 1 xattr.h 1 st_atim.tv_nsec 1 package-string: glusterfs 3.0.0 /lib64/libc.so.6[0x3a66a30280] /lib64/libpthread.so.0(pthread_spin_lock+0x2)[0x3a6760b0d2] /usr/lib64/libglusterfs.so.0(iobref_merge+0x2f)[0x37af83fe71] /usr/lib64/glusterfs/3.0.0/xlator/cluster/stripe.so(stripe_readv_cbk+0x1ee)[0x2b55b16c1b68] /usr/lib64/glusterfs/3.0.0/xlator/performance/stat-prefetch.so(sp_readv_cbk+0xf5)[0x2b55b14a39d2] /usr/lib64/glusterfs/3.0.0/xlator/performance/quick-read.so(qr_readv+0x6a6)[0x2b55b128c209] /usr/lib64/glusterfs/3.0.0/xlator/performance/stat-prefetch.so(sp_readv+0x256)[0x2b55b14a3c4c] /usr/lib64/glusterfs/3.0.0/xlator/cluster/stripe.so(stripe_readv+0x5fc)[0x2b55b16c28cd] /usr/lib64/glusterfs/3.0.0/xlator/mount/fuse.so[0x2b55b18d2665] /usr/lib64/glusterfs/3.0.0/xlator/mount/fuse.so[0x2b55b18d88ff] /lib64/libpthread.so.0[0x3a67606367] /lib64/libc.so.6(clone+0x6d)[0x3a66ad2f7d] --------- Here's the client configuration: volume client-stripe-1 type protocol/client option transport-type ib-verbs option remote-host gluster1 option remote-subvolume iothreads end-volume volume client-stripe-2 type protocol/client option transport-type ib-verbs option remote-host gluster2 option remote-subvolume iothreads end-volume volume client-stripe-3 type protocol/client option transport-type ib-verbs option remote-host gluster3 option remote-subvolume iothreads end-volume volume client-stripe-4 type protocol/client option transport-type ib-verbs option remote-host gluster4 option remote-subvolume iothreads end-volume volume client-stripe-5 type protocol/client option transport-type ib-verbs option remote-host gluster5 option remote-subvolume iothreads end-volume volume readahead-gluster1 type performance/read-ahead option page-count 4 #
