Hello list, how could this happen? The Server doesn't respond from time to time with a high load avarage. We found a suspicious smbd process: top - 13:43:07 up 1 day, 2:27, 5 users, load average: 32.49, 58.41, 37.95 Tasks: 1196 total, 5 running, 1190 sleeping, 0 stopped, 1 zombie Cpu0 : 14.7% us, 3.8% sy, 0.0% ni, 79.8% id, 1.3% wa, 0.0% hi, 0.3% si Cpu1 : 1.3% us, 84.6%

Recently we installed CENTOS 4.4 on DELL 2650 server. We found CPU load always on 3 and up if we run "top" or "w" to check. There is NO application run on this server why CPU load so heavy? ======= messages from check up === %w 11:31:56 up 20:02, 3 users, load average: 3.06, 3.03, 3.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT oracle pts/1

Dear all, I have installed DRBD 8.3.11 compiled from sources. However the backend block will freeze if there is high IO load. I use Remus to support high availability and checkpointing is controlled by remus for each 400ms. If I check the Iostat I got the idle CPU will decreasing extremely each checkpointing and when its reach 0% of idle cpu the local backing device will freeze and damage the

Hi Guys I''m trying to measure the traffic of domUs using vnstat without luck. My configuration: Debian 6.0.3 xen 4.0.1 vnstat 1.11 I''m using bonding with two network cards. auto bond0 iface bond0 inet manual slaves eth0 eth1 bond-mode active-backup bond-miimon 100 bond-updelay 200 bond-downdelay 200 bond-primary eth0 auto br0 iface br0 inet static

I'm wondering if R has functions to return pvalues with given x-squares and df. I googled for it but couldn't seem to find one. Appreciate any helps here. An example: df=4, x<- c(33.69, 32.96, 30.90) which are the statistic for chi-square, I'd like to get the corresponding pvalues for each values in x. Thanks. -Karen [[alternative HTML version deleted]]

The current llvm/llvm-gcc-4.2 2.6 branch passes all of the Polyhedron 2005 benchmarks built with its gfortran. The results compare as follows... Compile Command : gfortran -ffast-math -funroll-loops -msse3 -O3 %n.f90 -o %n benchmark gcc-4.2.4 llvm-gcc-svn llvm-gcc-2.6 llvm-gcc-2.6 at -m32 20081031 -m32 at -m32 at -m64 ac 18.30

I can't figure out why this function wont work. #Custom Function used fallInBand <- function(x){ #Assume the bands fall go up form 0 to 100 in intervals of 5 then from 100 to 1000 in intervals of 100. #returns the location (band number) if (is.na(x) == FALSE) { if(x < 100) {#bands of 5 if((x %% 5) >=0){#falls within the band Result = as.integer(x/5)+1

The previously posted benchnarks for gcc vs llvm-gfortran had one mistake. I was actually had the gfortran for 4.3.1 installed instead of that from gcc 4.2.4. Below are the polyhedron benchmark results for all three compilers... gfortran 4.2.4 Benchmark Compile Executable Ave Run Number Estim Name (secs) (bytes) (secs) Repeats Err % --------- -------

Guess you went through user lists and tried something like this already http://lists.gluster.org/pipermail/gluster-users/2018-April/033811.html I have a same exact setup and below is as far as it went after months of trail and error. We all have somewhat same setup and same issue with this - you can find same post as yours on the daily basis. On Wed, Apr 11, 2018 at 3:03 PM, Anastasia Belyaeva

Hi All, I put my Compaq R3000 UPS on NUT. Every once in a while the battery alarm light turns on, on the front of the UPS. Maybe once every couple of days or so. When that happens I get the following output in /var/log/messages: Sep 22 01:51:46 mail upscode2[90734]: Unknown response to UPDS: .20 MOUL1 Sep 22 01:51:46 mail upscode2[90734]: Unknown response to UPDS: 0119.20 MOIL1 Sep 22

Hello list, I am running rsync 2.5.5 on some Solaris 7 and 8 boxes. I'd like to sync different directories from one box to another. This is my include file: ppukweb2% more rsync-include-file /tmp/loris/testrsync1 /tmp/loris/testrsync2 /tmp/loris/testrsync3 This is the command I run: rsync -azv -e ssh --stats --include-from=/tmp/rsync-include-file ppukweb8:/tmp/loris and this is the

Thanks a lot for your reply! You guessed it right though - mailing lists, various blogs, documentation, videos and even source code at this point. Changing some off the options does make performance slightly better, but nothing particularly groundbreaking. So, if I understand you correctly, no one has yet managed to get acceptable performance (relative to underlying hardware capabilities) with

Hello everybody! I have 3 gluster servers (*gluster 3.12.6, Centos 7.2*; those are actually virtual machines located on 3 separate physical XenServer7.1 servers) They are all connected via infiniband network. Iperf3 shows around *23 Gbit/s network bandwidth *between each 2 of them. Each server has 3 HDD put into a *stripe*3 thin pool (LVM2) *with logical volume created on top of it, formatted

Hi all, I have an odd interaction on a CentOS 7 file server. The basic setup is a minimal 7.x install. I have 4 internal drives (/dev/sd[a-d]) configured in a RAID5 and mounted locally on /data. This is exported via NFS to ~12 workstations which use the exported file systems for /home. I have an external drive connected via USB (/dev/sde) and mounted on /rsnapshot. I use rsnapshot to back up

Hi all, This is my first post to the list, I hope someone out there can help! I am running xen 3.0.3, with CentOS 5.2 based Dom0 (kernel-xen-2.6.18-92.1.22.el5) Recently I have noticed some complete system lockups on a few different servers. Neither Dom0 or any of the guests respond to pings, connecting a keyboard and monitor to the system only shows a blank screen. Nothing is written to logs

Hi, I was hoping I could modify a locally mounted registry hive using regpatch and a .reg file but the -F argument seems to have no function. (Strace shows it ignores it and just operates on /var/lib/samba/private/hklm.ldb) Below is output with debug on. rfm6 at ubuntuSSDx64:cp /mnt/xp/WINDOWS/system32/config/software /tmp/software rfm6 at ubuntuSSDx64:/tmp/config$ sudo regpatch -d=10 -F

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Hi all We are implementing samba-ldap to act as an nt pdc and are seeing performance problems. We have a 1ghz, 3gb Ram, 36gb box that is running samba-2.2.5 and openldap-2.0.23 under redhat 7.3 with kernel 2.4.18-3. Clients are all Win2k SP3. All the ldap requests are to the localhost interface. The box is acting as the PDC for the domain, and also sharing diskspace and printers. When we get
