Hi, Are you using an rsync with ssh or just a standard mounted NFS share from the server to a local dir and rsyncing on that? I use rsync every day without these problems although I must admit I do it out of live hours (Internet only but no radio feed) "just in case", I've never noticed any problems though.
Its possible that the NFS buffers/threads are too small and causing problems. I normally set NFS mounts in fstab to rsize and wsize buffers to 32768 (I think the default is 8192). I read a while back that the max on one of the NFS versions is 32768 however it will auto negotiate to the maximum supported buffer size on both ends so there is no danger of completely killing it. There was also an option to increase the NFS threads. This page has some useful info: http://www.techrepublic.com/blog/opensource/tuning-nfs-for-better-performance/64 Regards, Wayne -----Original Message----- From: [email protected] on behalf of Robert Jeffares Sent: Thu 30/08/2012 00:26 To: User discussion about the Rivendell Radio Automation System Subject: [RDD] problems with rsync backup Creating a copy of /var/snd on a backup machine using rsync while the original machine is running rd [v2.x] the playout stops and the rdairplay screen blanks. This happens every now and then. At the same time rsync reports problems copying one of the files in /var/snd and says it's going to try again. the files are not being played at the time the files are random, but cancel and repeat produces the same result on the same files. the files all check out ok in rdlibrary I have the same problem using cp to a folder on the originating machine. It sems to be OK on smaller files but these are regular 3-5 min songs The originating machine is running a centos 64 bit appliance install and has a 1Tb and a 500Gb which the installer set up as a LVM all files are owned by rd:user and chmod 774 we seem to have plenty of ram and drive space. no memory hogging processes I am beginning to think it's one of the hard drives but there may be something basic I have missed.
