Hi!
This behaviour was already talked about on our group:

&forum_name=moosefs-users
So these errors were caused by a "disconnected" hdd. If you looked in the
cgi monitor you would see a disk with "damaged" status (it happens when
MooseFS encounters 3 errors in one mintue; it doesn't mean that the hdd is
really broken, but for the sake of the whole system, such disk gets
disconnected by the system).
On the other hand we strongly recommend upgrading MooseFS to the latest
version. There are lots of new things and bugfixes. You can wait for 1.6.25
which will be released next week.
Kind regards

Subject: [Moosefs-users] chunkserver crash/shutdown
Today, one of our chunkserver, running 1.6.20-2 crashed giving out the
following errors. Going thru the docs and couldn't find anything relevant to
it.
I also noticed 3-errors-in-60 seconds ruleset, is there anyway to increase
the threshold in order to avoid further disruptions ?
Thanks,
