I've turned off the VA-Sterling room for now as I've got my node defaulting to the Virginia room with a few other nodes in the state.
The Sterling, VA, USA repeater and WIRES-X node is now up and operational.
It is a full duplex WIRES-X node, C4FM Repeater, and FM Repeater in FM19ha run by KG4TIH.
This Yaesu DR-2X repeater on 70cm is set for analog and C4FM mode. The node is set to auto join the VA-Sterling (28558) room after an inactivity period of 10 minutes. When in this room or others all C4FM traffic will be sent to the Wires-X room and all signals received via the room will be transmitted via C4FM. The Wires-X features on some Yaesu radios will allow the user to control what room is connected.
Ceph has two forms of scrubbing that it runs periodically: Scrub and Deep Scrub
A Scrub is basically as fsck for replicated objects. It ensures that each object's replicas are all the latest version and exist.
A Deep Scrub is a full checksum validation of all data.
My Ceph cluster at home isn't designed for performance. It's not designed to maximum availability. It's designed for a low cost per TiB while still maintaining usability and decent disk-level redundancy. Here is some recent tuning to help with performance and corruption prevention....
Sterling, Va now has a Wires-X node (100% digital with full control) on 439.800MHz.
Note: If/when coordinated frequencies come in and the associated repeater is up, the frequencies will change.
Previously I posted about the used 60-bay DAS units I recently acquired and racked. Since then I've figured out the basics of using them and have them up and working.
I was getting this from podman on a CentOS 8 box:
"error from slirp4netns while setting up port redirection: map[desc:bad request: add_hostfwd: slirp_add_hostfwd failed]"
It was fixed by killing off all podman and /usr/bin/conmon processes as the user that I was running the commands as. Note: Don't do that as root using killall unless you limit to only your user.
The underlying error may have been running out of FD.
While setting up my Ceph cluster on a set of Dell R710s, one with 60 disks attached to it, I found that I needed to raise fs.aio-max-nr to around 1,000,000. SELinux also needed to be disabled. Once that was done the normal cephadm osd install worked great, even with 60 disks.
$ cat /etc/sysctl.d/99-osd.conf # For OSDs fs.aio-max-nr=1000000
