vm_thread_new: kstack allocation failed with vm.kmem_size="1536M"
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 expected it to run fine, I just wanted...

6.3-RELEASE-p3 recurring panics on multiple SM PDSMi+
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

recommended setup for amd64 7-STABLE with ZFS, Samba 3.2 and possibly ACLs?
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

Preparing to compare Solaris/ZFS and FreeBSD/ZFS performance.
Hi.
I''m all set for doing performance comparsion between Solaris/ZFS and
FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I
think I''m ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB
RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the
links to disks are the bottleneck, so I''m going to use not more than 4
disks, probably.

repeatable crash on RELENG7
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 ?

current zfs tuning in RELENG_7 (AMD64) suggestions ?
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
ste...

[SO]HO Software RAID5 server: which implementation should I choice?
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,

A box of mine running RELENG_7_0 and ZFS over a couple of disks (6
disks, 3 mirrors) seems to have gotten stuck. From Ctrl-T:
