Hi everyone, We seem to be having issues on multiple CentOS 7.3 machines. The problem seems to revolve around polkitd. At some random time, polkitd seems to stop responding on my systems. Along with this, there might be hundreds of defunct pkla-check-authorization processes. If I reboot, then things are fine for a while. I don't see any activity in the unabridged journal to suggest anything

I asked a similar question about a year ago and didn't get any answers. So I thought I'd try again. What do people do to get their syslog messages on CentOS 7 into a remote ELK stack. I've tried lots of things involving rsyslog, filebeat, redis, logstash and so on in lots of different configurations but nothing really works. I can get rsyslog to talk directly to logstash (acting as

I'll try that...I was using instructions I found on the internet for single-user/maintenance mode.?? From the grub screen you enter 'e' and modify the linux16 line...etc. Okay, I'll try that next.

I recommend having LUKS be "under" LVM. the layers would be: /dev/sda -> partition (/dev/sda1) -> LUKS (/dev/sda1_crypt) -> LVM physical volume -> volume group -> logical volume -> filesystem The layers described above are how the Ubuntu installer sets up an encrypted LVM filesystem. As far as I know, TRIM is passed through LUKS and the LVM layers if it's available

My Dell Precision M3800 running Fedora works great but is really starting to show its age, and I'm thinking about getting a new Mac M1-based laptop as it would really be useful for Video production. But I really need to have a IA64 CentOS 7/8 VMs running locally for development as I'm often on the road and flaky Internet makes it a necessity to keep productivity up. I've been

Hi everyone, I'm having some odd system behavior on two CentOS 7 machines. I suspect that the trouble is related to polkitd and dbus I think that the following error message is a key clue, but I'm not sure how to continue troubleshooting it:. --------------------------begin log----------------------- Jul 15 10:00:27 localhost rtkit-daemon[1609]: Warning: PolicyKit call failed: Did not

You can install any R packages from CRAN using the ?"install.packages()" command form within R itself. This will download, compile, and install the packages into your personal user account. you might need to install some supporting *-devel RPM packages via "yum", but otherwise, it should work. --------------------------------------------------------------------------- Jason

I don't use ELK at the moment, but is this helpful? % journalctl -f --output=json The above command prints the continuous output of the systemd journal in json format.

Hi everyone, I'me having trouble with a CentOS 7 guest running on a Hyper-V host. For some reason, the CentOS guest randomly drops its IP address. Running "systemctl restart NetworkManager" on the console will restore IP connectivity without a reboot. I think that DHCP is timing out, but I'm not sure what to do about it. Is there a way to tell NetworkManager to keep trying after

Hi, I want to perform goodness of fit test for multinominal distribution. The easiest way would be to use Chi2, but the measurment errors are not normally distributed. I thought about using some bootstraping method to perform the analysis. How can I do it in R?

I have put a preliminary version of factanal in a package at http://www.stat.ox.ac.uk/pub/R/fa_0.1-1.tar.gz and would appreciate feedback. In particular 1) What else you might want. Please give precise references with algorithmic details, as that has been a major problem for me. 2) Some convincing examples of factor analysis. Most (literally) of the ones I have looked at are local maxima, not

Dear R users: is there a package, similar to varclus in SAS or varclus in S, ported or written for R? Also, is there any other package in R that was designed for grouping the variables under different measures of distance (in cases where data is non-Gaussian, autocorrelated, and so on).

Hello, I've had a quick look on the list and can't find an answer to this niggle. Whilst debugging some code, I noticed that looping variables in R are not local to the loop as seams common in procedural languages. For example consider the following piece of code: for(i in 1:3){ cat(i,"") for(i in c("a","b","c")){ cat(i,"")

Folks I'm looking for a solution for backups because ZFS has failed on me too many times. In my environment, I have a large amount of data (around 2tb) that I periodically back up. I keep the last 5 "snapshots". I use rsync so that when I overwrite the oldest backup, most of the data is already there and the backup completes quickly, because only a small number of files have

Folks I was impressed with the description of VDO (Virtual Device Optimizer?) in the RedHat documentaion, so much that I tried to use it. The tutorials led me to a few commands. I built a VDO device on top of two USB disks which I made into a Logical Volume, and I was ready to go. In my test case, I had a file set of about 600 GB. There was 5 TB of space between the two disk LVMs. So, I
