LVM repairing or back to regular ext3?
by Paul 16 Jul '06

16 Jul '06

Can anyone point me in the right direction for correcting errors on an HD when using LVM? I've tried e2fsck and indicates bad block. I've tried with -b 8193, 16384, and 32768 and no good. I've found some info about reiserfsck on google, but this utility doesn't seem to be included in Centos4.3. I did find it on my old FC1 box. I am thinking now I really should have went with just regular 83 Linux ext3 partitions. Arrgghhh. And if I want to switch to 83 Linux instead of 8e LVM, whats the best way, or at least a feasible way? I can pop another drive in if I need to move data around, but I don't see how, as I can't mount the LVM partition (hda2). -- ^^^^^^^^^^^^| || \ | Budvar ######|| ||'|"\,__. | _..._...______ ===|=||_|__|...] "(@)'(@)""""**|(@)(@)*****(@)I

RE: [CentOS] Emailing from Command Line
by Mark Schoonover 16 Jul '06

16 Jul '06

Thanks Guillermo. The thing is, I can send test emails outside my domain no problem. I can't send emails to my internal smtp server from any CentOS system on my internal network. I discovered that I didn't have an MX record in tinydns for my internal network, so I added that. After testing, no changes - any email that's destined to any address to my domain bounces with the error message listed below. I'm not a sendmail person, would rather do without it, but I don't think I can simply remove it from CentOS. I could install postfix, or qmail and see how that works, but it's serious overkill for sending simple emails internally... Had hopes ssmtp would work, but that doesn't either. Works on Gentoo systems, just not CentOS. A hair puller that's for sure, but I'll keep banging on it until it works. Thanks for all the ideas, if anyone can think of anything else, I'll try it!

And use sendmail as a client of that other smtp, your ISP smtp. after having that configured you could try to send emails somewhere else, @ yahoo.com <http://yahoo.com> or @ gmail.com <http://gmail.com> as suggested here. regards, Guillermo Garron On 7/14/06, Karanbir Singh < mail-lists(a)karan.org <mailto:mail-lists@karan.org> > wrote: Mark Schoonover wrote: > Karanbir Singh wrote: >> Mark Schoonover wrote: >>> ----- Transcript of session follows ----- >>> 550 5.1.2 < admins(a)amgt.com <mailto:admins@amgt.com> >...

Try sending emails elsewhere ? to an @ gmail.com <http://gmail.com> maybe ? Alternatively, have you tried nut ? it should be available in most repo's. Does a fairly good job of sending emails from the command line ( and is what I tend to use ) -- Karanbir Singh : http://www.karan.org/ <http://www.karan.org/> : 2522219@icq _______________________________________________ CentOS mailing list CentOS(a)centos.org <mailto:CentOS@centos.org> http://lists.centos.org/mailman/listinfo/centos <http://lists.centos.org/mailman/listinfo/centos>

Problems with installation
by Horchler, Joerg 14 Jul '06

14 Jul '06

Hi all, I try to install CentOS 4.3 for X64_64 on a new Dell PowerEdge 2950. I have two problems: 1. After booting from CD I pressed 'return' to start installation (BIOS-support for USB-keyboard works). After probing the hardware my USB-Keyboard is not working anymore. Dell removed ALL PS/2-Interfaces so I have to use USB. When I start installation with 'linux noprobe' the keyboard still is working and the installation starts. 2. After the installation starts it tries to load the storage drivers. In the case for this hardware it tries to load megaraid_sas. But it can't load the driver without an error. The installer just says:"loading megaraid_sas" for hours and hours (the complete last night). When I start with 'linux noprobe' I'm able to look at another console (alt+F2) and can try 'lsmod'. The output for megaraid_sas is 'loading' and not 'live' (again: for hours). Does anyone knows how I can solve these problems? Is kudzu not working correct for the first one? Thanx Jörg

The problem is one of them is something that we will not do (as MS will not support extending AD with Services For Unix(SFU)). The other is simply configuring kerberos and pam on the linux system. No problem there from what I can tell. Ticket cache: FILE:/tmp/krb5cc_0 Default principal: userid(a)dom.ain Valid starting Expires Service principal 07/05/06 07:23:03 07/05/06 17:23:47 krbtgt/DOM.AIN(a)DOM.AIN renew until 07/06/06 07:23:03 Kerberos 4 ticket cache: /tmp/tkt0 klist: You have no tickets cached The problem though is configuring winbind from the console (all of the linux systems are nothing more than the kernel, ssh and the few apps necessary for the system to do it's job). All the online examples I have been able to find use the linux GUI. Does anyone know of a document (or mind sharing) how they installed and configured the samba 3 winbind daemon to map SID's to unix uid's/gid's? That would eliminate the need to extend the active directory schema. thanks, Greg

Any way to drop the size of the created image? Ex: disk is 100G and I no longer need all the extra space. perhaps only 20Gig image instead of the full 100Gig. Thanks, Jerry
