Re: [CentOS] netinstall
>How can I insert a disc which is already inserted? What am I missing? Well, pretty simple... You don't have the correct disc "already" inserted. Its a netinstall, hence the "net" so it needs the net. Its also only a couple hundred megs, so that should indicate it doesn't have the full tree available. Grab the dvd if you want to install from the "same" disc, or choose another method. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] netinstall
Hi, I just tried to install CentOS 6.3 netinstall and got the error message -- Disc Not Found -- The CentOS disc was not found in any of your CDROM drives. Please insert the CentOS disc and press OK to retry. How can I insert a disc which is already inserted? What am I missing?

Welcome to NAT444. Aka 'double-NAT' or 'carrier-grade NAT' where your connection's WAN port is further NATted at the ISP's border router, and the ISP itself is using RFC 1918 space and minimal publicly routable IP addresses. There was a special IPv4 address block allocated for this purpose relatively recently; discussion can be found in the NANOG mailing list archives. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Centos machine sometimes unreachable

Could someone have moved non-computer hardware, like, say, a > desk or chair, or there's been some utility work, and the cable run's > impacted occasionally... or stepped on? Or even vibrated loose. As a lesson in 'vibrational torque' aka the 'whimmy diddle effect' (see https://en.wikipedia.org/wiki/Gee-haw_whammy_diddle ), I'll relate what happened to a machine in our newly rennovated Research Building Data Center. The machine in question is an EMC Clariion CX3-80 with three 40U racks. Each rack needs two 30A 208V single-phase circuits. Due to the way the electrical was run for this machine, one UPS is powering one side of the three cabinets, and a second, smaller UPS is powering the other side. The secondary feed's L6-30R's are mounted to the pedestals of the raised floor; the primary feed's L6-30R's are in cast aluminum pendants lying on the subfloor, with the receptacles pointing up. An electrician was drilling two 1/4 inch holes for concrete anchors for a conduit run sixteen feet away from the CX3-80 a couple of days ago, and I started getting a bunch of alerts from the CX3-80. I looked at the array, and yellow lights were lit on all three cabinets. Hmm, what's up with that; power loss to the whole side of the array? I lifted the panel over the L6-30R's in the pendant on the subfloor, and all of the twist-lock plugs were unplugged from their pendant receptacles! No one was in the data center but the electrician, and the power was fine right before he started drilling the two small holes. I personally had plugged in the plugs that morning, and had set the cords to apply the correct torque to maintain the twistlock, and had fully seated and locked the plugs in the receptacles. The vibration of the hammer drill sixteen feet away hit the right resonance, and 'whimmy diddled' the plugs out of their receptacles. Thermal cycling can also exert torques, and one of my preventive maintenance steps in all of our data center spaces with twist lock plugs is to reseat the twistlock once per quarter. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] write-intent bitmap
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, On CentOS 6 I noticed very high load after installing and while the md raid 1 array was syncing. I found lots of complaints about performance degradation for md raid with enabled write-intent bitmap. See http://blog.liw.fi/posts/write-intent-bitmaps/ for example. So I wanted to it off. I let it sync and then removed the bitmap. Do you know of a way to not enable a write-intent bitmap while installing? I had a look at the Kickstart section in Upstreams Installation guide but found nothing. My only idea was a %post section stop the sync (hmm, but how, I think I have to consult mdadm(8) remove the bitmap start the sync again Maybe there is better way? Some kind of trick? I realize that I can set a bigger chunk size (but how big?) for the bitmap. But again, how do I do it while installing/kickstarting. - -- Kind Regards, Markus Falb -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlA4mosACgkQYoWFBIJE9eV5awCfSahv1b7DJ7YdHiJVI6ewjx8x De0An215k6nzYH+lk+1hsGMSzM59TnMV =580F -END PGP SIGNATURE- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
