I'm getting out of memory errors trying to do 'rsync -av /foo /bar' where /foo is a local dir and /bar is an ocfs2 filesystem running on an ~ 6T ATA-over-Ethernet box. The only non-stock config option I'm using is O2CB_HEARTBEAT_THRESHOLD=91 because the coraid can get a bit bogged down under high load. Is this a known leak? is there a better way for me to instrument things to give someone more information? The machine in question has 16GB of RAM and the same in swap, so it really should be up to the task... Thanks for your help, --pj
#cat /proc/meminfo #cat /proc/slabinfo #uname -a As in, provide the above dumps when the box is close to out-of-mem.

It is millions of little files or hundreds of large files? What is the RSS of rsync when you run out of memory? http://samba.anu.edu.au/rsync/FAQ.html#5 http://lists.samba.org/archive/rsync/2002-July/003160.html /Brian/ -- Brian Long | | | IT Data Center Systems | .|||. .|||.
