https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277389 --- Comment #27 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to pascal.guitierrez from comment #26) I'll note that I never used mount_nullfs explicitly at any point but I still got the huge difference in VNODE results in "vmstat -z" when doing your test iozone runs, all based just on the: nullfs_load="YES" vfs.nullfs.cache_vnodes=0 vs. not distinction. There may be implicit/automatic use involved? ( zfs_load="YES" both ways. ) Because of your hangup status, doing a "vmstat -z" and saving the output before doing the read iozone test would be good. Both with and without the 3 lines for comparison/contrast: the vmstat -z output differences should indicate if internally any difference is being made. I made the suggestion because I've no way to tell if what I've been reporting contributes to your context or not: I've never seen the OOM activity or hangups. But the huge Wired figures that even survive the ARC shrinking suggest potential contribution to an OOM status. -- You are receiving this mail because: You are the assignee for the bug.
