A simple and hopefully usable FreeBSD live CD

2010-08-22 Thread Ed Schouten
Hello all, A couple of major releases ago, we had a FreeBSD disc1.iso which also included the livefs. Nowadays the livefs comes on a separate disc. This livefs disc has a couple of issues in my opinion: - The livefs disc does not feature any installsets, which means if your system has 1 CD-ROM

uma: zone fragmentation

2010-08-22 Thread Andriy Gapon
It seems that with inclusion of ZFS, which is a significant UMA user even when it is not used for ARC, zone fragmentation becomes an issue. For example, on my systems with 4GB of RAM I routinely observe several hundred megabytes in free items after zone draining (via lowmem event). I wrote a

uma_zcreate: additional arg for uminit/fini

2010-08-22 Thread Andriy Gapon
What do you think about adding an argument to uma_zcreate that would be passed on to uminit/fini as an additional parameter? Perhaps (probably?) to dtor/ctor. The idea is to provide additional context to uminit/fini. One immediate use is more efficient compatibility code for OpenSolaris

ZFS arc_reclaim_needed: better cooperation with pagedaemon

2010-08-22 Thread Andriy Gapon
I propose that the following code in arc_reclaim_needed (sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c) /* * If pages are needed or we're within 2048 pages * of needing to page need to reclaim */ if (vm_pages_needed || (vm_paging_target() -2048)) be changed to if (vm_paging_needed())

1. Be sure to give the CD a try and share your experiences. Does it work? Does it crash? Is it usable for you? If not, why not? 2. Would a CD like this be a good addition to the provided install media? Does it actually solve shortcomings of the existing media? If people think it's a

Do you by any chance have a graph showing kstat.zfs.misc.arcstats.size behavior in addition to the stuff included on your graphs now? All I can tell from your graphs is that v_free_count+v_cache_count shifted a bit lower relative to v_free_target+v_cache_min. It would be interesting to see what
