Subject: megaraid_sas driver bug
Date: Sat, 25 Jun 2016 17:13:50 +0000 (UTC) [thread overview]
Message-ID: <loom.20160625T191237-500@post.gmane.org> (raw)
I don’t know if this is the right place to report this and whether this is
more like a Centos kernel issue.
Since Centos 6.8, the megaraid_sas driver seems to be somewhat broken –
which as I understand is a backport of the up-to-date driver to their kernel
version. It is still partially usable, but as soon as I need to rebuild an
array, instead of the scan message at the end I get a bunch of kernel error
messages. There are so many of these that the kernel logger uses too much
CPU and eventually the log fills up the partition, so the server needs to be
rebooted. So technically I lose all hotplug functionality.
Probably the same thing happens when the array degrades.
I’m sending this report here, because there is absolutely no mention of
similar problems on the internet, yet the problem is fully reproducible and
real.
I’m using Dell Perc 6i at the moment.
Thanks
