I have the same problem, I've just converted my data volume to a HAMMER file system on my server. I receive this message:
«hammer: System has insufficient buffers to rebalance the tree. nbuf < 3969» I have 512MB of SDRAM on it. I guess it's time for me to upgrade this :-) SR Le 2011-01-31 16:17, Matthew Dillon a écrit : > :On Sunday 30 January 2011 22:43:01 Matthew Dillon wrote: > :> :I still get this warning.
