comment “Spare” disk in a 2-disk mdadm RAID1 array?
It looks like the kernel route would need a custom kernel for Debian Squeeze LTS, so... trying a hunch. The partitions are identically sized to the byte, but maybe between GPT and 4096 byte physical sectors, there could be a slightly different usage of data... I recreated the partition and added 200M, I also turned down the logging on iptables and it's running again. Will know if it worked tonight.

dmesg is overrun with some iptables messages, I've got it logging some firewall stuff. Syslog has a pair of repeating messages. I'm including them in the question, along with a link which discusses them... I might need a kernel upgrade. I do have some odd hardware for an older kernel.

I removed the failed disk and replaced it, this is the result afterwards. Two of the three partitions on the disk properly resynced.

I replaced the disk already, this is the outcome after trying to rebuild. I can remove and re-add, it takes about 6 hours, then quietly returns to this state. I've done that twice.

comment HPUX Logging Logins
It's a shame it's so complex. I guess I'll have to hack something together with last, lastb, logger, awk and cron or tail. Brutal. Our wtmp and btmp files seem to be corrupt too... got to love commercial UNIX. I really appreciate the insight, just disappointed there isnt a "log to syslog" option I missed.

It's a mix, they're using telnet mostly... it's an old system used to administer legacy devices on a secure network. No ssh for now. Do they all use different methods to log?

comment Are there network connections that don't use the WiFii card or the Ethernet port?
re: netstat, A note on "if they're currently active". UDP can send packets in an instant with no assumption of receipt or creation of a session, this makes it very easy for it to slip past checks using netstat. If you want to monitor your communications, you need to use a sniffer or configure firewall rules to report your traffic. An external firewall being preferred if you don't trust the system being monitored.

comment Installing XRDP on Cent OS 6.5
I found the following very helpful when troubleshooting, I could follow the errors in the config more easily. note that the vncserver session isn't needed, xrdp will launch its own using its own session manager: # xrdp --nodaemon& sleep 2; xrdp-sesman --nodaemon

comment Tools for Monitoring Steal Time (st)
The root cause of this one turned out to be that the ISP had the VM incorrectly configured. The guest was being told it had more cores than it actually did. This seemed to cause havoc with the scheduling. The ISP couldn't provide intelligent tech support, but we were able to "prove" the problem by disabling odd-numbered cores in /proc. Never a problem since.
