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 .

erase disk
by Phil Dobbin 29 Sep '13

29 Sep '13

Hi. I have a CentOS server (a Dell 860) with two drives in it. One is running CentOS 6.4 which I want to keep & the bigger 400GB drive has Debian 7 on it which I want to erase & use for backups. Which is the best way to go about achieving my intended goal? The Debian drive is not mounted when Centos is booted. Any help appreciated. Cheers, Phil... -- currently (ab)using Arch Linux, CentOS 5.9 & 6.4, Debian Squeeze & Wheezy, Fedora Spherical & That Damn Cat, Lubuntu 12.10, OS X Snow Leopard & Tiger, Ubuntu Quantal, Raring & Saucy GnuGPG Key : http://phildobbin.org/publickey.asc

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 .

That did the trick. I used lp instead of scanner because I'd already made myself a member of lp.

The only issue I've noticed is that if I leave paper in the all-in-one, it wants to copy, not just scan. I'm not sure whether that is a change. It's been an OS ago since I wanted to scan. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily

greetings list, i am creating a new thread because of comment made by; From: Nicolas Thierry-Mieg <Nicolas.Thierry-Mieg(a)imag.fr> in thread "Subject: [CentOS] erase disk". in past readings about; erasing an hdd, forensics of hard disk drives, dban, destroying hdd i submit these links for those who may wish to further their knowledge on primaries of hdd forensics; hard disk drive forensics - Ixquick Web Search https://ixquick.com/do/search?q=%22hard+disk+drive+forensics%22&lui=english About 28 results hdd forensics - Ixquick Web Search https://ixquick.com/do/search?q=%22hdd+forensics%22&lui=english About 8,410 results forensics of hard disk drive - Ixquick Web Search https://ixquick.com/do/search?q=%22forensics+of+hard+disk+drive%22&lui=engl… About 5 results [actually, 1] forensics of hdd - Ixquick Web Search https://ixquick.com/do/search?q=forensics+of+hdd&lui=english About 819,695 results of the above, #3 relates to a book; Spin-stand Microscopy of Hard Disk Data (Elsevier Series in Electromagnetism) [Hardcover] which is available thru "amazon.com" and i would imagine other good book supplies. at amazon, there is; /*quote Book Description Publication Date: April 11, 2007 | ISBN-10: 0080444652 | ISBN-13: 978-0080444659 | Edition: 1 This book provides an in-depth exposition of spin-stand microscopy of hard disk data which is a new technique recently developed and extensively tested by the authors of the book. Spin-stand microscopy is the first magnetic imaging technique where imaging is performed ex-situ on a rotating disk mounted on a spin-stand. This technique is one of the fastest scanning-based microscopy techniques. It is non-invasive and has nano-scale resolution. For these reasons, it provides unique capabilities for the visualization of magnetization patterns recorded on hard disks. /*etouq i do not have book, tho if i have $237.50 and nothing better to spend it on, i may purchase it. as can be seen by "results" of above links, there is a lot of information available related to "Subject:". something that, in my current and passed readings, many do not seem aware of is that even tho 'dban' can be use to remove data, it _does_not_ guarantee removing, beyond recovery, data on a hard disk. head gap wear and bearing wear factor in highly as to whether or not data can be readily recovered, and to a greater factor, if hdd is mounted vertical or horizontal. if one wishes, as mentioned in two of post, "sledge hammer" and "hydraulic wedge", are good ways. much better, and more assured is 'degaussing' disk platters, even which will leave a small bias. best way, of insuring data removal is to scrape disks clean of coating, or to burn off coating. i have used latter. -- peace out. in a world with out fences, who needs gates. tc.hago. g .
