Hi all, I have a strong Dell server running RHEL5.5 every now and then the server hangs (SSH access is frozen) and when attemping to login the prompt hangs and after a while the message " can't update CMOS clock from 2 to 47 CIFS VFS No respone for cmd 114 mid 188" only a reboot causes it to work properly again. i tried fsck'ing with no luck. I must say the server does work very hard often, but I was wondering what could be the problem. Thanks! --- Dolev

Anyone using CentOS Active Directory like system?
by Tennant, Jacob 30 Sep '13

30 Sep '13

I am the IT Development Specialist for a small community college and our CIO has asked me to explore an alternative to Microsoft Active Directory as we are separating from our parent university and funding is tight so we were looking into CentOS with 389 Directory Server. Any advise or suggestions would be very helpful. Jacob Tennant

ghostscript-8.70-14.el5_8.1.x86_64 & hylafax+ 5.5.3
by Gregory P. Ennis 30 Sep '13

30 Sep '13

I am having some problems with hylafax+ on CentOS 5.9 converting files into appropriate tiff files that are faxable; the problem is apparently fixed in ghostscript 9.07. The CentOS repositories currently have ghostscript-8.70-14.el5_8.1.x86_64 I surely appreciate the maintainers of the repositories; can any of you direct me to whom maintains ghostscript on the repository or when 9.07 is planned to be included. I would also like to request that ghostpcl be included, but I am not certain who or how to ask. Thanks for your assistance. Greg Ennis

Intel 10G X520-2 and iscsi storage poor performance
by Götz Reinicke - IT Koordinator 30 Sep '13

30 Sep '13

Hi, we have a storageserver (Centos 6.4) with a dualport Intel 10G X520-2 Adapter. A QSan P600Q-D316 Storage is configured with 8*SATA Drives raid 5 for test, connected trought a Cisco UCS 6100 Series Fabric Interconnect 10G Switch. I formated the storage with ext4 defaults, one volume and got r/w rates about 10MB/s some up to 40MB/s .... VERY POOR.... So we returned the storage to our dealer and they tested the hardware and did some IO Meter Test with VMware ESXi 5.1 Server -> virtual Windows 2k8-R2 on the Qsan Storage. The VM did some r/w IO Meter Benchmark up to 1000 MB/Sec. Better. Hardware looks o.k. Than they installed a Windows 2k8-R2 server and attached the QSAN. The r/w speed is about 400-500 MB/s. After that the dealer installed a Centos 6.4 as I did and the r/w performance is back to our results .... up to 40MB/s .... What the hell? Are the default driver and settings so bad? I know and researched a lot of tuning options like buffers, new drivers etc. We did not check that for now, but are'nt there some defalut values and settings which apply as well to be much faster? Or in other words, are some realy simple hints and suggestions to a) debug / find the bottleneck and b) to increase the performance to the same level as windows? Thanks a lot for any help and feedback .

to lvm or not to lvm - why/when to use lvm
by Götz Reinicke - IT Koordinator 27 Sep '13

27 Sep '13

Hi, I was wondering, why/when it is useful or when should I avoid to use LVM. I think the big advantage of LVMing is if you modify (rezising, ...) disk and filesystem layouts "a lot". Are there any real pros or cons for following situations regarding e.g. management and speed? e.g.: I do have a server system raid for which the disk layout will not change; e.g. /var /usr /home will not change much in size. OR I do have some file storage shares (iscsi raids) up to some TB each on one big storage device. Sometimes (e.g. after a server crash) it is useful to remount the storage to a different server. Should I use LVM on the iscsi storage volumes? Any suggestion and comment is welcome . Regards .
