Question How to refresh lvm-backed virtual disk in libvirt
How can I grow a libvirtd VM's LVM-backed virtual disk online, without rebooting the vm. My host has an LVM VG for VMs. Each VM disk is an LV to the host. It's easy to grow the VG by adding a PV and extending the LV. But the VM doesn't "see" the new space without rebooting. How can I get t...

Question Desktop Multiplexer for Linux? (GNU Screen for GUI apps)
GNU Screen and Tmux allow you to run command-line programs on a server, and 'disconnect' from them but let them keep running remotely.

Comment Post #285831 Thank you! That looks much nicer and I'll remember that tip in the future. I was relying on the formatting toolbar at the time. Can it be made to insert the different types of ticks based on if the selected text is multi-line or not?

Comment Post #285831 Problem is I wish to discriminate based on the host-name from which the message originated. I still very much want local emerg messages to print to console. Just not emerg messages from other hosts on the LAN.

Question How do I prevent remote syslog events from printing locally?

I set up rsyslog years ago to listen on UDP:514 and save syslog messages it receives from any host to `/var/log/netsyslog/${HostNameOrIPHere}.log` and that wor...

Answer A: How can we grow this community?
I stopped using a former Q&A Network of Sites because of their poor political choices. Before I left, I noticed a number of people who also objected to those politics renaming their usernames to ${FormerName}Reinstate${Someone} where $FormerName was their former username, and $Someone was a person...
