[CentOS] slapd 100% cpu
Greetings, We have been attempting to set up a centos ldap server and then tried to log in with a user account specified in our ldap environment on a centos workstation. As soon as we attempt any kind of login from the centos workstation, be it via gdm or su ldap_user, the slapd process on the ldap server goes to 100% cpu. Is this normal behaviour? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Detect if a drive is USB?
I'm updating a script to work with EL6 (previously worked on EL5) and am
stumped, google fu is failing me. Part of the script is to detect USB
drives and mount them. Previously, It worked something like
isUsbDevice() {
if [ -f /sys/block/$1/usb ] ; then
// do stuff
fi;
}
but I don't find the "usb" file/directory anywhere to be found any more
on el6. I've tried the output of lsusb and lsusb -v but in no case have
I been able to find anything there matching anything in /sys/block that
matching anything in lsusb's output.
Given an available drive (EG: /dev/sdk) how can I reliably tell it's
interface type? (USB/SATA/PATA/SCSI ?)

Re: [CentOS] Detect if a drive is USB?
Answering my own message for posterity's sake: This line will output "E:
ID_BUS=usb" for any block
device connected to a USB bus:
udevadm info --query=all --name=$file 2>/dev/null | grep -i BUS=usb;
The basic idea is to
1) use udevadm to get all info on device $file (where $file is a string
like "sde")
a) send all errors to /dev/null.
2) grep the output of udevadm for the string "BUS=usb" which appears on
USB devices.
Note that you must have $file defined with a device name which I got by
listing the contents of /sys/block.
Good luck! Also, if anybody has a better solution, please reply. The
above appeared to be "good enough"
to finish porting my admin script.

[CentOS] automatic repartitioning
Hello all. Does anyone have any suggestions for making centos cloud images that can automatically repartition the root device to resize the filesystem? All the Ubuntu UEC images do this, so using the same image, you can launch cloud instances of a variety of flavors and the VM instance will repartition the root disk and resize the fs. The Ubuntu images utilize scripts in the initramfs dpkg that handle this. Just curious if anyone has been able to replicate this functionality. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As an example, I run three OpenLDAP servers that are accessed through a load balancer from 400+ clients. Total CPU usage of all three servers by slapd averages a bit less than 2 hours per day.

Re: [CentOS] automatic repartitioning
Yes, it can be done. Kickstart configs are the solution. Note: I generally do not have more than one LV or physical partition that is set to --grow. But it was out of simplicity and I didn't have a need. Given the online documentation, it does look like you can specify more than one. But it does appear to only apply to LVM LVs. Look for the following line in the documentation [0]. logvol / --vgname=myvg --size=1 --name=rootvol --grow --percent=90 I won't get around to testing this until Monday, so if you find something out before then please share! I can see this being plenty helpful for a web server kickstart I have (where /var grows and / is fixed ... might be nice to have them balance out a bit).

Thanks Nux, I used your image, and I see resizing works as expected. Odd, I too use the cloud-init rpm, but mine just ignores it. I can take what you have and make it work.
