Are there any ways to improve/manage the speed of pvmove? Man doesn't show any documented switches for priority scheduling. Iostat shows the system way underutilized even though the lv whose pe's are being migrated is continuously being written (slowly) to. Thanks! jlc

...night, in addition to our tape backup paradigm, an rsync script is run which mounts /dev/sdb1 on /mnt/sysinfo and copies system data from sda1 there. /dev/sdb1 is a 146GB drive. The script then mounts /dev/sde1 on /mnt/userdata for a copy of /home and /home/adminusers. /dev/sde1 is a wholly underutilized 300G drive. I'd like to move the contents of /home/adminusers from /dev/sdd1 to /dev/sdc1 and use that underutilized drive elsewhere. What's the least invasive way of doing this given the hardware and partitioning on my system? Thanks in advance, -Ray

Hi, I have the following happen to me after the restart of one of my servers: out of my 3 PRIs (all configured with the same technical settings), the last one isn't coming back. It's underutilized (chances it didn't get a call since my reboot), if it makes a difference . The PRI goes from provisioned to unprovisioned, and I get this regularly: [Jun 22 09:03:48] WARNING[30723]: chan_dahdi.c:2790 pri_find_dchan: No D-channels available!

...n last level cache (LLC). I.e. times that we have to go to DRAM (SLOOOW). The getVA codepath show up strongly and we see the memcpy into the output. We may want to consider a nontemporal memcpy to at least avoid polluting the cache. These misses contend on the DRAM bus (although currently it may be underutilized and so adding more parallelism will help to keep it busy, but only up to a point). https://reviews.llvm.org/P7947 --event=dTLB-load-misses These are dTLB misses for loads (on my machine, it corresponds to any time that the hardware page table walker kicks in: https://github.com/torvalds/linux/...

Здравствуйте, xen-users. Just test domU IO perfomance: sda1 configure via phy:/dev/sdb1. Benchmark with dbench (dbench -D /usr/src -s 10 -t 120) - 102 Mb/s Native sistem (mount /dev/sdb1 /mnt && dbench -D /mnt -s 10 -t 120) - 140 Mb/s How i can speedup dbench? -- С уважением, Vitaliy mailto:vitaliy.okulov@gmail.com

for s10u2, documentation recommends 3 to 9 devices in raidz. what is the basis for this recommendation? i assume it is performance and not failure resilience, but i am just guessing... [i know, recommendation was intended for people who know their raid cold, so it needed no further explanation] thanks... oz -- ozan s. yigit | oz at somanetworks.com | 416 977 1414 x 1540 I have a hard time

...workload in each VM. VM in node1 got 1500sec exec time while VM in node2 got 1990sec exec time. Previously, I also installed same xen version with 2.6.31 (dom0) pvops linux kernel. At that time, there was no such problem in same exp configuration. Currently, I''m suspecting underutilization of LLC cache since the lowered dom0 kernel version.

I received a recommendation to check out Asterisk, as a platform to host a simple DTMF response system, something like: Setup up VoIP endpoint on Linux/FreeBSD system Answer incoming VoIP phone calls User enters 100#, perl script plays back "foo" User enters 101#, perl script plays back "fum" User enters 102#, perl script looks up something in

Hi, I`ve done a few tests with comparing a two personne conf call (both phones next to each other) and a simple call from one phone to the other. In the simple call, there is virtually no delay when I am speaking. In the meetme call, on an underutilized server, with a transcoder card for G729, with one two participants, I have a relatively large delay (1/3 of a sec maybe?). There is an obvious difference in delay. Is there anything I can do about that, or is this just something to live with when using Meetme? Using Asterisk 1.4.33.1,...

Greetings, I would like to announce the availability of a new site dedicated to finding and creating jobs in the Asterisk VOIP field. I've created this site, after noticing there are no sites dedicated to providing quality job postings and hiring abilities to people in the field. http://www.asterisk-jobs.com It's in beta now, so if you notice any problems please let me know at

Dear all, I am managing a departmental purchase of an Opteron based workstation/server for scientific computing on which we will be running R. The environment will probably be either Unix/Linux or Solaris and the amount of RAM will be 8-16Gb, depending on the number of processors. My main concerns are the following: 1. How much does R benefit from passing from one processor to two/four

Hi All. I'm trying to run a simple model from Baayan, Davidson, & Bates and getting a confusing error message. Any ideas what I'm doing wrong here? # Here's the data.....

So, to follow up to my previous thread, we just successfully migrated our NFS-based mail cluster from qmail pop, courier imap, and bincimap to dovecot 1.1rc1. Overall the transition was very smooth, the only unexpected adjustment was having to implement ntpd on each box, rather than doing an hourly ntpdate against our local ntpd server, to prevent dovecot from crashing itself from too much

...as KVM. It may even be useful in containers and in a native physical operating system. And, yes, it is machine-independent so should be easily portable to ia64 too! Basically, instead of moving the ownership of all physical memory between one domain and another, tmem instead collects system-wide underutilized memory into a "pool" in the hypervisor and provides indirect access to that memory so that it can serve the needs of domains without necessarily being directly addressible by the domains it serves. It is implemented with a small set of (hyper)calls that enable pages to be copied betw...

I am new to Asterisk and VoIP. I have been given the task of setting up a telephone network in US and India. When customers call the US location, the calls should route to India (using VoIP) and handle there. The Indian location should be able to call Us numbers using the Voip to save money. The solution should be flexible enough to support initial of 5 simultaneous calls with the option to

Hi In light of the fact that RSpec mocks are going into maintenance mode in the near future, I was wondering what everyone was switching to. I liked the look of FlexMock most, so gave that a shot. However, there''s a few things that don''t work well with RSpec due to the traditional differences in the way Test::Unit cases are written vs RSpec specs. (One spec per
