So, I have a farm of machines runnign 7.1/amd64, all of which have 16 gig of memory in them. This afternoon, as an experiment, I altered loader.conf to have these two lines in it: vm.kmem_size="1536M" vm.kmem_size_max="1536M" This is what I do on machines running ZFS - these machines are not, however running ZFS, and do not have the zfs module loaded. I just wanted to see if they would run OK with those kernel settings (as I may put ZFS on them in the future) I expe...

We have 10 SuperMicro PDSMi+ 5015M-MTs that are panic'ing every few days. This started shortly after upgrade from 6.2-RELEASE to 6.3-RELEASE with freebsd-update. Other than switching to a debugging kernel, a little sysctl tuning, and patching with freebsd-update, they are stock. The debugging kernel was built from source that is also being patched with freebsd-update. These systems are

I gave the AMD64 version of 7.2 RC2 a spin and all installed as expected off the dvd INTEL S3200SHV MB, Core2Duo, 4G of RAM In the past it had been suggested that for zfs tuning, something like vm.kmem_size_max="1073741824" vm.kmem_size="1073741824" vfs.zfs.prefetch_disable=1 However doing a simple test with bonnie and dd, there does not seem to be very much difference in 4 configs. Am I better off just with the defaults ? The machine is acting as anoffline storage site, so a...

Hi, could anyone give recommendations (or share experience) regarding using ZFS: - FreeBSD 7-Stable (amd64 with 8GB RAM) + special tuning necessary (apart from increasing kernel memory to 1 or more GB for ZFS) - Samba 3.2 + ACLs possible directly under ZFS? + recommended compile options? - NFS - email (imap) - jails (I have seen some problems exist with using snaphots within

While trying to speed up nanobsd builds, I mounted /usr/obj on a ramdisk and found my box crashing. Thinking it might be hardware, I tried a separate machine, but with the same results. I have 4G of ram (i386). Am I just running out of some kernel memory ? If so, is there anything I can adjust to prevent this, yet still use mfs in this way ? mdconfig -a -t malloc -s 1800M newfs /dev/md0

Hello, freebsd-stable. Does somebody use some software RAID5 on FreeBSD in real production system? I want to build storage server for my home: RAW photos, multi-layer PhotoShop files and FLAC-encoded music consume a lot of space, and they should be availible both from desktop & notebook. Also, all photo-content is unique, so I need some insuranse from single HDD crash. I understand,

after trying to mount my zfs pools in single user mode I got the following message for each: May 18 09:09:36 gw kernel: ZFS: WARNING: pool 'cache1' could not be loaded as it was last accessed by another system (host: gw.bb1.matik.com.br hostid: 0xbefb4a0f).

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed
