centos 5 reboot diagnosis
by Agnello George 25 Sep '09

25 Sep '09

Hi we use cent OS 5.2 on all our production server, just today one of or mail server had a reboot and we dont understand why ... usually we get a alert if a system was loaded up ... but this system just reboot .... may be it could be a power failure ...( is there any way to check this ) .. but that is the last optiopn i am guess as the server is in IDC . With dmidecode and biosdecode .. i just get server / bios info . In the Messages and Dmesgs ... i cant really pin pont the issue . Is there any thingi am not doing or any thing i am supposed to figure out the reson for this reboot. -- Regards Agnello D'souza

Re: [CentOS] OT: What's wrong with RAID5

In the end, either using RAID-DP or RAID4, the capacity is the same. It's the array's way of saying it's not really safe to operate a 14 disk RAID-4 group in the event of a drive failure. Also performance will suffer greatly with such a large data:parity drive ratio. NetApp RAID DP (what you have): http://www.netapp.com/us/library/white-papers/wp_3298.html > What's wrong with RAID5, is there any technical limitation with RAID5? Most onboard RAID controllers are absolute crap, RAID 5 isn't as easy to support as RAID1/RAID0, as extra processing time and code is needed for the parity stuff. I wouldn't use them for even RAID 1 though. If it's onboard, and I want RAID then I'll use software RAID. Unless it's a SCSI/SAS RAID controller often times those onboard RAID controllers are of decent quality. RAID 5 as implemented by most disk vendors does have issues at least with large SATA disks - Why RAID 5 stops working in 2009 - http://blogs.zdnet.com/storage/?p=162 A couple vendors that I know of - 3PAR(which I use) and Compellent don't suffer from this limitation because they virtualize the disks, I can't speak too much for Compellent's architecture but 3PAR doesn't RAID physical disks, they raid portions of each disk, when a disk fails, every disk in the system participates in rebuilding that failed set of arrays, which results in upwards of a 10x improvement in recovery time and 90%+ drop in system impact while the arrays are rebuilding. This virtualization also allows you to run multiple levels of RAID on the same spindles for different purposes. The likelihood of suffering a double disk failure on such a system during a RAID rebuild is probably quite a bit less than suffering a triple disk failure on a RAID-6 system which runs RAID on whole physical disks. At full system load my array can recover from a 750GB drive failure in less than 3 hours. Our previous array took nearly 30 hours to recover from a 300GB(SATA) drive failure. If on my array the disk is only half utilized, then it will take half the time to rebuild, as only written data is rebuilt, no point in replicating portions of the disk that haven't been used, though other vendors do this because they don't have the architecture to support sub-disk rebuilds. My own 200-disk array has more than 86,000 individual RAID arrays on it, most of them being RAID 5(5+1). Array management is automatic and transparent to the storage system I just tell it how big a volume I want and what type of data protection. For performance reasons I'm migrating my RAID 5(5+1) to 3+1 next year after I add more space. I miscalculated the growth of the big driver of space on the current system so I had to migrate to 5+1(RAID level migrations have no service impact either on my array). On my system there is roughly only a 9% performance drop from RAID 1+0 to RAID 5+0, so in many cases running RAID 5 on my array is about the same as RAID 1 on other arrays, it's that fast. RAID 6 has a pretty good performance hit vs RAID 5 due to the extra parity disk, on some arrays the performance hit is even greater as the array calculates parity twice, NetApp I think has as good a RAID 6 implementation as there is, though they can't get around writing the parity information to two different disks. nate

logrotate and regular expressions
by Sol Fulop 25 Sep '09

25 Sep '09

I am trying to use logrotate to rotate our web logs for our various vhosted sites to cut down on space and rotate out old logs that are not necessary to keep around personally. What Im curious to find out, is how supported extended regular expressions is within the logrotate.conf file. More specifically, will logrotate be smart enough to decipher the following: /path/to/logs/access_log.www.*.(com|org|net|us) The filename format for my logs are: access_log.www.domain.com/net/org/us. Thank you in advance. Sol

opensc - pkcs#11 smartcard support for EL4
by John R Pierce 25 Sep '09

25 Sep '09

does anyone know if any repositories have OpenSC built for EL4 ? I've been struggling with building this myself, trying to get an Aladdin eToken working with OpenSSL so we can use it for client authentication of an SSL session.

Yes - and for those suggesting ubuntu as better for a non-technical user I think the real question is whether the user will do any of their own changes (like adding new programs) and updates. If they do, ubuntu is probably a good choice. If they will ask you to do it for them, then it would be the system that you are most comfortable with maintaining. -- Les Mikesell lesmikesell(a)gmail.com

Driver for Logitech QuickCam E2500 series webcam
by Andrew Allen 24 Sep '09

24 Sep '09

Does anybody know where I can find a driver for a Logitech E2500 webcam. I'm running CentOS 5 on my desktop and want to add a webcam for skype use. If I can yum install a driver from one of the repos that would be great. Andy
