RPM Spec and subpackage architecture
by Ross S. W. Walker 06 Dec '07

06 Dec '07

Are there any RPM wizards out there that know how to specify a different architecture for a subpackage in a spec file? I have a package that has a binary component and a non-binary component that I would like split into 2 packages one, the binary which is architecture dependant and the other 'noarch'. I haven't found a spec file that does this yet :-( Ross S. W.

weird load values
by J. Potter 06 Dec '07

06 Dec '07

Hi List, I'm stumped by this: load average: 10.65, 594.71, 526.58 We're monitoring load every ~3 minutes. It'll be fine (i.e. something like load average: 2.14, 1.27, 1.03), and then in a single sample, jump to something like the above. This seems to happen once a week or so on a few different servers (all running in a similar application). I've never seen the 1 minute sample spike as high as the 5 or 15 minute samples. Seeing as that last value is a 15 minute period, well, it doesn't seem possible that one can have a 500+ 15 minute sample without having observed a spike in the 5 minute sample at least 5 minutes before. Also, there aren't 500+ processes on these systems -- it's typically around 100 total processes (ps auxw | wc -l). (Is there a way to see the total count of kernel-level threads?) Thoughts? best, Jeff Linux someHostName 2.6.18-8.1.8.el5 #1 SMP Tue Jul 10 06:39:17 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux CentOS release 5 (Final) 09:31:15 up 65 days, 17:45, 2 users, load average: 0.92, 200.91, 371.30

A few questions about remastering
by Mário Gamito 06 Dec '07

06 Dec '07

Hi, I've searched all over Google, but couldn't find a proper answer to my needs. I've installed CentOS 5.1 only with the packages I need and then made a few of my own. Now, here's what I need: a) To integrate my self-made packages in a remasterized DVD; b) That the install process of the new version skips package choosing, i. e., when it reaches this stage it just installs all the packages of the new version; c) And last, but not the least, how to remasterize the new DVD with the original packages I've installed, plus the ones I've made. Any help would be appreciated. Warm Regards, Mário Gamito

Filesystem that doesn't store duplicate data
by rsivak＠istandfor.com 06 Dec '07

06 Dec '07

Is there such a filesystem available? It seems like it wouldn't be too hard to implement... Basically do things on a block by block basis. Store md5 of a block in the table, and when writing a new block, check if the md5 already exists and then point the new block to the old block. Since md5 is not guaranteed unique, might need to do a diff between the 2 blocks and if the blocks are indeed different, handle it somehow. When modifying an existing block that has multiple pointers, copy the block and modify the new block. I know I'm oversimplifying things a lot, but something like this could work, no? Would be a great filesystem to store backups on, or things like vmware volumes... Russ Sent from my Verizon Wireless BlackBerry

Re: [CentOS] Re: SCSI bad block table display
by Brent L. Bates 06 Dec '07

06 Dec '07

Hugh Cruickshank, you are not mistaken. SCSI drives do keep bad block information on the drive. I've also been using this for YEARS on SGI's under IRIX. Under IRIX, the command `fx' is used to partition SCSI drives, exercise them, format them (which is something one never does to SCSI drives), spare out bad blocks, list the bad block table, etc., etc.. -- Brent L.

Re: Load Balancing
by Rajagopal Swaminathan 06 Dec '07

06 Dec '07

Greetings, First let me thank the gentleman who allayed my fears about CentOS 5.1's "yum update" download size. but all the same it turned out to be in megabytes. not to mention the k3b *roasted* couple of DVD's to uselessness and I am still giving explanations to the stupid ancient,retired, former stupid cretin bean counters masquerading as "managers" and "management Accountants" on. a piddly amount wasted. I found this thread in the GMANE list as I subscribed to this list rather late. Let me propose a solution: Let two nodes run the greatest ever CentOS 5.0 on two nodes. Let two nodes of the cluster run DRBD 0.8 and export block devices in Primary/Primary mode and the GFS be mounted on them. Let the NFS export be a managed service of the Cluster infrastructure from these nodes exporting the NFS on a cluster managed virtual IP as rw. let n (as permitted by the infrastructure) nodes import NFS as client on their nodes. and do the job I am seeing a 3-node cluster exactly that far past fes days and naturally, given the maturity of CentOS 5, do that for, hopefully, ever. In the ,eantime of the replies hopefully the readers will enjoy the solutions proposed by me regards, Rajagopal
