"Raghavendra G" napisa?(a): Hi, I've been trying to reproduce your problem. Some observations, * I've run into 'No such file or directory' errors, but it was due to dd not creating the file due to block size being 0 (bs=0). * As per dd error msgs, there is a space between '/' and 'mnt' (/ mnt). dd: opening `/ mnt/glusterfs/24427/30087.20476 ': No such file or directory please make sure that the file is getting created in first place (file may not be created due to invalid parameters to dd, like bs=0 in above case). * since I am not able to reproduce it on my setup, is it possible for you to try out the test with - afr-self-heal turned on - afr-self-heal turned off - following options control afr self heal option data-self-heal off option metadata-self-heal off option entry-self-heal off regards, On Wed, Dec 10, 2008 at 7:51 PM, <a_pirania at poczta.onet.pl> wrote: I have a problem. I have run two servers and two clients. On both clients operate in the background loop: for ((j=0; j< $RANDOM; j++)) { PLIK=$RANDOM.$RANDOM dd if=/dev/urandom of=/mnt/glusterfs/$KAT/$PLIK bs=$RANDOM count=1 dd if=/mnt/glusterfs/$KAT/$PLIK of=/dev/null rm -f /mnt/glusterfs/$KAT/$PLIK } If both servers are connected to everything is fine. If one stops working after several minutes will go back to the server, a client I have: dd: opening `/ mnt/glusterfs/24427/30087.20476 ': No such file or directory dd: opening `/ mnt/glusterfs/24427/30087.20476 ': No such file or directory dd: opening `/ mnt/glusterfs/24427/18649.25895 ': No such file or directory after a few seconds, everything is working again. I think that the client is trying to read the file from the new server. I think this is not work? check it. I do not know is important but the system for tested is Linux Debian 4.0 (2.6.18-6-xen-amd64) on Xen 3.0.3-1 -------------- next part -------------- An HTML attachment was scrubbed...
