Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
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:

Hi Kelly,
Try running 'iostat -xdmc 1'. Look for a single drive that has
substantially greater await than ~10msec. If all the drives
except one are taking 6-8msec, but one is very

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...

Login script doesn't run
Hi,
The login script has worked for our win98 computers since the dawn of time (or
there abouts). Then something happened or I did something and the login script
doesn't run anymore. I can run it manually. This was version 2.2.3a.
I started smbd with -d10 and didn't see any call for a script. Is the login script
mentioned in a working system?
In an effort to fix this, I deleted and

I've indeed no argument with how you've phrased that idea.
The motivation for responding as I did above was two-fold. First, the idea
to which I was responding--as phrased--felt like a Kafka trap:
YOU have transgressed. WE don't have to tell you why.
The accusation is the evidence.
etc.
Second, I wondered if adopting the language of 'offensive' and 'unsafe'
might help illustrate the point that anyone can claim to be triggered by
something.
