According to Stefan Bethke: > $ sysctl kern.maxvnodes vfs.numvnodes vfs.freevnodes > kern.maxvnodes: 100000 > vfs.numvnodes: 87681 > vfs.freevnodes: 7600 > > Is there a rule of thumb what maxvnodes should be tuned to? Not sure, I max'ed it to 200000 and the machine has not locked up since. Try that, 300000 if not and so on. The thing is, receiving snapshots is going to generate a lot of inodes/directories so vnodes shortage may be your problem. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr In memoriam to Ondine : http://ondine.keltia.net/
