[Bug 1648561] Re: HTX (htxubuntu) DASD exercisers fail
If os-prober is not running, I don't see what else might be poking the
disks to cause the warnings. We must ignore the other warning messages
that were listed from syslog earlier and look at it a different way. Is
the Redhat system showing the same write errors?
Is HTX doing raw writes to disk or are you writing files on a
filesystem? Again, what filesystems exist on the disks being exercised?
Could it be that the filesystem or the disk fails as a consequence of
the HTX workload?
Reassigning to 'linux' so that further investigation can be done on the
issue.

I noticed on a different system that has htxubuntu-424 installed along with a patch from defect sw372840 that the sdb exercisers is running just fine. It currently has a cycle count of 2 and current stanza of 5. The device on this other system is exactly the same drive type.

[Thu Dec 1 01:23:10 2016] hfs: can't find a HFS filesystem on dev sdb1
Linux has failed to detect file systems on sda1, sdb1 disks, causing write
failures for HTX exerciser. Similar fails are reported for nvme disk also in
Linux kernel log.

Linux errors are being by os-prober. I ran os-probe manually and
FS fails got logged in Linux log. So os-probe got invoked while HTX
was running. This caused write fails for sda1, sdb1 disks along with
nvme disks and also logged Linux errors.

What operation was tried while HTX was running, once these errors
were seen ? Was it apt upgrade or some thing else ?

HTX was started using htx command line commands. From then on, the
system was monitored through "System Live Monitor" No other commands
were executed by a user. This failure happened during an overnight
run. I believe that the Ubuntu OS was loaded to automatically load
Security Fix's which is required.
