With Linux 2.6.33.4 everything runs fine. I do not know where to search for known bugs in xfs. /var/log/messages shows a lot of lines: Jun 19 11:43:15 amd2000 kernel: vmap allocation for size 4194304 failed: use vmalloc=<size> to increase size. Jun 19 11:43:15 amd2000 kernel: xfs_buf_get: failed to map pages What to to?

Strange. There have been no fixes to the vmap allocator nor to the XFS using this. What other modules are you ising? Maybe they increased their amount of used vmalloc space. For now the only thing you can do is using the vmalloc= kernel paramter to increase the vmalloc space. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 5+ messages in thread
