Howdy, Does anyone happen to know where I can locate the changes that were integrated into a specific RPM update? I checked the wiki, the rpm query output and bugs.centos.org, but wasn't able to locate a changelog for the latest kernel update. Thanks, - Ryan

The problem did not go away. On CentOS 5, the Teac DV-516D DVD/CD reader can mount a CD, without any problem. However, it sees a DVD as blank. On Windows XP, it works perfectly, with CD and DVD media. I sent an email to Teac Tech Support, asking for the URL where I could download their Diagnostics for the drive and got this reply: >Unfortunately, no diagnostics are available as checking the read capabilities within >Windows XP is most than acceptable. If the drive does not work properly within >Windows or any other PC, then the drive needs to be repaired or replaced. Disappointing and I will probably never purchase Teac components again. The box is dual boot (WinXP & CentOS 5). Years ago, I purchased SystemSuite 4. I installed that and ran their generic diagnostics on the Teac DVD/CD reader and it passed. I am not positive the Teac drive is working perfectly, but I have a high level of confidence in it. My belief is that somewhere, there is either no support for the Teac DV-516D in CentOS 5, or, that something required to automount a DVD in it is not configured properly. It can mount a CD without any problem.

Alan: Thank you for all of the ideas you've had in this thread! I strongly suspect that your idea of replacing the Teac CD/DVD-ROM with something else, is the only way to end this problem. My belief now is that there is no support to auto mount a DVD in that Teac drive, in CentOS 5. Probably, when it was my box and it worked OK, it was with a prior release of CentOS or Fedora Core and something has changed and the auto mount support for that drive (for DVD media) was removed. I rarely use Windoze, but it was very helpful, to be able to test the same CD/DVD-ROM drive and verify that it works perfectly under Windoze. I was able to mount the DVD in a terminal and install the RPM I wanted to install OK, so that also makes me believe the drive is OK. Lanny

You forgot to include the part about being able to walk on eggs, without breaking them! :-) Sounds like a very honest job description. If nobody on this ML is interested (and qualified) consider posting on http://www.dice.com/ Not sure what it would cost you to post the job requirement there, but it's a very active site. I discovered it last Saturday. My background is mostly Aerospace, and after not working for many years, I need to go back to work. I'm a contractor, and your job description partially describes what we encounter, when we go to a temporary job assignment: abuse & lots of stress. :-) However, we get paid by the hour and for O.T. :-)

Alan: Today, I removed the Teac DV-516D DVD/CD reader, manufactured October 2004, in Japan, from my daughters box. I temporarily hooked it up in my box. The exact same problem! I could not see the contents of a DVD-R, but, I was able to see the contents of my Knoppix Live CD, without any problem. So, I did not bother with the PITA of removing the DVD/CD reader from my box, and trying that one in my daughters box. I booted my daughters box with my Knoppix Live CD V. 5.1.1 and it also showed the FC6 Install DVD to be blank. I suspect: (a) The Teac DV-516D DVD/CD reader is not supported in this kernel or somewhere else in CentOS 5. or (b) The DVD/CD reader is somewhat faulty. (c) However, Windows XP shows it to be "OK" and I can see the contents of the FC6 install DVD OK, in Windoze. Also, I can boot from the CentOS5 and FC6 Install DVD's, without any problem. And, I was able to mount the FC6 Install DVD, in a terminal and install the RPM I wanted to install, without any problems. Thank you, very much, for your time and ideas! Lanny

X just died then restarted
by fred smith 01 May '08

01 May '08

Just had a weird thing happen that I've never encountered before. Running Centos 5.x (updated) on 32-bit (Athlon XP). Was going along in Firefox when suddenly my screen went black and the hard drive light came on mostly steady for several seconds. After a little bit I got back the X login screen. It normally comes up on F7, but F7 was dead (with some text I'll paste in below in case it means anything to someone) and (since I have another dedicated app on F8) it came up on F9. The last few entries in /var/log/messages, which are about the right time, are: Apr 30 18:34:44 hostname restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory Apr 30 18:34:52 hostname kernel: NVRM: not using NVAGP, an AGPGART backend is loaded!

FWIW, I'm running the Nvidia 96.43.01 drivers, direct from Nvidia and not any repository. Any ideas?

determining correct size for LV copy operations
by Kai Schaetzl 01 May '08

01 May '08

I have some problems with copying LV volumes and determining correct size. For instance, if I want to copy an LV from one machine to another. I dd the LV to a file on the other machine, then dd the file to the new LV. That fails, because a few MB are missing. source: LV Name /dev/VolGroup01/LogVol01 LV Size 4.62 GB target: LV Name /dev/xenvm/lvmtest1 LV Size 4.62 GB Both were created with lvcreate -L 4.62GB, but there's obviously a small rounding or whatever difference. The size of the physical extents seems to be different. I can determine the size of the output file -rw-r--r-- 1 root root 4966055936 Apr 30 21:19 lvmtest1.img That is 4849664K which is the smallest size unit that lvcreate accepts. lvcreate -L 4849664K --name lvmtest1 xenvm - and then it fits. But I hope there's a better way to determine the *exact* size? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

CentOS 4.5 - mounting remote windows fileserver using smb or cifs
by Tom Brown 01 May '08

01 May '08

Hi I need to mount a windows share on a CentOS 4.5 box running stock kernel etc - I have tried using cifs and also smbfs My fstab looks like //share/name /mount/point smbfs username=user,password=password,uid=useridhere 0 0 or the same using cifs When i try and mount that i get the following errors depending on the share type smbfs: mount_data version 1919251317 is not supported CIFS VFS: cifs_mount failed w/return code = -22 i would have thought that cifs was the way forward but any ideas? These use creds are being used on an ancient 7.3 box and they work fine thanks

Boot disk changes from /dev/sda during install to /dev/sdb on first boot
by Jeff Larsen 01 May '08

01 May '08

CentOS 4.6 x86_64, Dell PE2950 with DRAC5, onboard SAS RAID 1, 2 arrays. After booting installed system, /dev/sda exists but does not appear to be a hard disk. fdisk -l displays nothing for sda. CentOS is on /dev/sdb and the second RAID 1 array is now /dev/sdc. It's been suggested (in the Dell Linux mailing list) that it is related to the virtual CD device of the DRAC. But why would it change after install? Is it perhaps a difference in drivers that are available in the installer vs. the live kernel? How can I find out what /dev/sda is? Any way to force the drive order from the CentOS side? No relevant options that I have found in BIOS or RAID setup. bash-3.00# ls -l /dev/sd* brw-rw---- 1 root disk 8, 0 Apr 29 05:15 /dev/sda brw-rw---- 1 root disk 8, 16 Apr 29 05:15 /dev/sdb brw-rw---- 1 root disk 8, 17 Apr 29 05:15 /dev/sdb1 brw-rw---- 1 root disk 8, 18 Apr 29 05:15 /dev/sdb2 brw-rw---- 1 root disk 8, 19 Apr 29 05:15 /dev/sdb3 brw-rw---- 1 root disk 8, 32 Apr 29 05:15 /dev/sdc /dev/cdrom points at /dev/hda mount /dev/sda /mnt yeilds 'No medium found' When virtual CD media is connected via DRAC, it is found at /dev/cdrom1 which links to /dev/scd0 -- Jeff
