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

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

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

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,

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.

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

Hi, I am a Newbie for R. I just installed R-base on my notebook with openSuSE 11. However, I always got compilation errors in installing add-on packages. For example, when installing "igraph" I got the following error: ___________________________________________________________________ * Installing *source* package 'igraph' ... checking for gcc... gcc checking for C compiler

Hi, during some experiments with many guests I get crashing Dom0s because of too less memory. Actually the OOM killer goes ''round and kills random things, preferably qemu-dm''s ;-) The box in question has 128GB of memory, I start with dom0_mem=8192M (or 16384M, doesn''t matter). I also used "dom0_mem=8192M,min:1536M", but that didn''t make any

Hello! I was trying to build OpenOffice using all of my 4 CPUs. To be able to do other work on the machine comfortably, I ran the build under nice, and assigned real-time priority to the two Xorg processes. The build started at about 23:10 last night, and hung at 23:46. The procstat output for the make's process group is: PID PPID PGID SID TSID THR LOGIN WCHAN EMUL

I just took the x64 CentOS 5.1/Xen system I've been working on and upgraded from 2GB to 4GB of memory. Fresh minimal install of the OS (to remove some 3.2 stuff I had done trying to make PCI passthrough work). No special options, just a flat out default install. Dom0 is incredibly slow, I haven't tried DomU's yet to see if they are affected. X in particular is impressively slow

Hi. (Im am sending this to the "stable" list, because it maybe kernel related.. ) On 9.1-RELEASE I am witnessing lockups of the openldap slapd daemon. The slapd runs for some days and then hangs, consuming high amounts of CPU. In this state slapd can only be restarted by SIGKILL. # procstat -kk 71195 PID TID COMM TDNAME KSTACK 71195
