WD RE4-GP Dropped From Raid
Hi All,
I have a WD RE4-GP which dropped an Adaptec 51645 RAID controller. I ran a
smartctl short test on the drive and it failed with a read error. So I ran
the Western Digital's own diagnostic software (DLGDIAG), both the short
and extended test on the drive and it passed with no errors. So I ran the
smartctl short test again and again it failed. I then ran smartctl long
test and that

Some thoughts about EL 6
Many people seem to wait for the announcement of CentOS 6.0, so I want
to share some test results I did with SL 6.0..
The actual 6.0 kernel can NOT allocate tape buffers when the server is
heavily loaded at least on some LSILogic hardware.
There is a big problem of slab buffer increase that can cause
reboot/freeze of the server under load. Reported by many and verified by
me :-(
So perhaps

Any update on 5.6 / 6?
Hi,
Despite the mailing list and twitter I did not find any updated info on
either versions regarding the current status.
So, what is the current status of both versions? (like 60%)

Accountsservice in CentOS 7.3
Is there any known problem with accountsservice-0.6.35-12 with NFS users?
After logging in via lightdm they are not "remembered" and there is no
entry created to /var/lib/AccountsService/users
Downgrading to accountsservice-0.6.35-9 resolved that issue

centos6 not using /etc/gdm/custom.conf
In CentOS5 you were able to create a server section in /etc/gdm/custom.conf such as
[server-Standard]
name=Standard server
command=/usr/bin/Xorg -br -audit 4 -s 15
chooser=false
handled=true
flexible=true
priority=0
After this change, Xorg would run with the -br -audit 4 -s 15 options.
Unfortunately in CentOS6 this is not the case. It completely ignores anything put into custom.conf as far

Centos 5.4 kernels for NFS4
Do CentOS 5.4 users still have to use the RedHat preliminary kernels
(http://people.redhat.com/jlayton/) for getting a NFSv4 safe kernel or
have the patches been incorporated into CentosPlus kernels?
Or is kernel-2.6.18-164.3.1.el5 somewhere in the queue?
Thanks in advance!

2.6.18-194.26.1.el5 NFS4 race conditions?
Are there any known race conditions with 2.6.18-194.26.1.el5 x86_64 and
NFS4?
Today a user managed to shut down two identical Intel servers by copying
a simple text file via NFS4.
Reverting back to 17.1 made the error disappear.
On other non-identical hardware the error was not reproducible (so it
must be a combination of hardware and this special kernel revision).

No kernel-debuginfo for actual kernel?
After a crash I tried
wget
http://debuginfo.centos.org/5/x86_64/kernel-debuginfo-2.6.18-194.32.1.el5.x86_64.rpm
as usual.
But for 32.1 there is no kernel-debuginfo.
Is there any reason for that?
Thank you in advance!

mdmonitor not triggering program on fail events
Hi,
Can anyone help me with this since I want to get it done "the correct
way"
I'm trying to make mdmonitor to execute a program when it detects a fail
event automatically.
Currently, from what I see, init is calling mdmonitor with these options
mdadm --monitor --scan -f
(note that the --program is not there)
and this is in my /etc/mdadm.conf

Lost raid when server reboots
Hi all,
I have setup a raid1 between two iscsi disks and mdadm command goes well. Problems
starts when i rebooted the server (CentOS 5.4 fully updated): raid is lost, and i
don't understand why.
"mdadm --detail --scan" doesn't returns me any output. "mdadm --examine --scan"
returns me:

Disabling services in CentOS 5.5
Hello all,
I have been doing some searching for information about disabling
services within a CentOS 5.5 install. I have found a few different
opinions, and wanted to ask for some feedback.
First off, the system is running a LAMP stack to serve a web
application. It will only be doing email to send occasional messages
out (sent via the application only). It will not be receiving email

7.3: Gnome workspaces mirrored
An user is using 2 displays and configured Gnome to "Static Workspaces
only on primary display on" using gnome-tweak-tool
Till 7.2 it was working as expected. After upgrading to 7.3 the content
on the primary screen gets mirrored to all workspaces.
When switching to "Static Workspaces only on primary display off"
everything is working as expected on 7.3, too.
Any ideas?

Spurious Segmentation Fault after upgrade to 7.4
After upgrading approx. 50 machines to 7.4 we discovered a reproducible
SegFault of one of our commercial programs we use.
This SegFault does not occur on CentOS 7.3 and it occurs only on Xeon
E3-1230 V3, Xeon E5-2690 and Xeon E5-2697 v2.
It does NOT occur on Xeon E5-2697 v3 and Xeon E3-1231 v3, AMD Ryzen and
older Core I7-9xx.
It is not dependent of the kernel, we switched back to an CentOS

Is kernel-3.10.0-693.11.6.el7 tested with old hardware?
Today we tried to update machines w/ Core2 Duo E6750 from
3.10.0-693.11.1.el7.centos.plus to 3.10.0-693.11.6.el7.centos.plus and
the machines did not boot due to a kernel panic.
Before we dig any further I wanted to know if the 11.6 kernel has been
tested on old hardware, too, or if the problem is well known but not
documented (yet).
Thank you in advance!
