Re: [CentOS] GNBD and DRBD kernel mods

Hmm, I have to disagree: First check the current kernelversion: [root@bartje ~]# uname -a Linux bartje 2.6.18-8.1.8.el5.centos.plus #1 SMP Mon Jul 16 08:49:50 EDT 2007 i686 athlon i386 GNU/Linux Check for kmod-drbd: [root@bartje ~]# modprobe drbd [root@bartje ~]# lsmod | grep drbd drbd 180488 1 Install the gnbd-kernel mod.

Problems reading a backup data DVD
by Mark Hull-Richter 20 Aug '07

20 Aug '07

I wrote a bunch of files to a backup DVD about two months ago and now neither of my drives will read it. I get mount errors from "not a directory" to something like "unrecognized file system type" and so on, usually after a really long wait and a notice about how the drive is write-protected (duh). Here's what happened most recently: # mount /dev/hdc /mnt mount: block device /dev/hdc is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdc, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so # dmesg | tail -40 hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: ide_intr: huh? expected NULL handler on exit hdc: ATAPI reset complete end_request: I/O error, dev hdc, sector 5118720 Buffer I/O error on device hdc, logical block 639840 hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: ide_intr: huh? expected NULL handler on exit hdc: ATAPI reset complete hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error } hdc: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 } ide: failed opcode was: unknown hdc: ide_intr: huh? expected NULL handler on exit hdc: ATAPI reset complete end_request: I/O error, dev hdc, sector 64 isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16 Is there any way to read what's on this DVD (so I can back -up the files again, hopefully with better results)?

open port 46929
by Craig White 20 Aug '07

20 Aug '07

results from 'netstat -tlpn' gives me a line... tcp 0 0 0.0.0.0:46929 0.0.0.0:* LISTEN - googling for port 46929 doesn't turn up anything and so I don't have a clue what process this belongs to. Do I have to start capturing activity on this port or is there a better way to find out what this port is about? -- Craig White <craig(a)tobyhouse.com>

Mark: Welcome to the club! Your secondary question is related to my very recent thread: Re: [CentOS] Re: Automount configuration problem Johnny wrote, a few days ago, that gnome-mount handles this. Someone else had pointed out that it is *not* an automount problem. When I verified the gnome-mount package, it apparently is fine. I'm stuck with this problem on my daughters box. I can (usually) mount a DVD on her box manually, as root, but that's not something I am going to teach my 6 year old or my wife to do. I don't want them running as root. I am running the Firewall and SELinux (permissive mode) on my box and on daughters box. Works perfectly on my box. In my daughters box, in the same drive, it will mount a CD OK but not a DVD. If you find a solution for this, please post to the ML, because I'm sure we are not alone. There's probably a configuration file that isn't 100% correct or permissions incorrect, but I don't know which file. Lanny

OT: Suggestions for database for physicians patient records?
by Lanny Marcus 20 Aug '07

20 Aug '07

This is very OT. If list readers can point me in the right direction, to other mailing lists, or web sites for recommended databases, that will be much appreciated! My wife's doctor wants to move records, for approximately 6000 patients (over a 12 year period), from paper (18th century) to a database (20th century). The data entry will be a PITA, for his secretaries, regardless of what software he goes with. I did some reading about MySQL, and I also did some googling for Linux+database and there are many other databases out there. One requirement is that one field be variable length (patient history: surgeries, treatments, etc.), which I suspect might vary from 200 words to 3000 words. That field size needs to be very flexible. If there are "front ends" that will make it easier for his secretaries to input patient records to the database and access it, that will be a "plus". It would also be a plus, but, it's not mandatory, if they can do this in Spanish. It's a small office (2 surgeons, nurses and secretaries) so I suspect there might be 4 to 6 workstations connected to the database server, maximum. I would like to help him get the best possible solution. Something with a large user base, excellent documentation and an active ML, like CentOS, is the goal. Thanks much! Lanny

Install on a usb flash drive
by Jerry Geis 20 Aug '07

20 Aug '07

I all, I was thinking about installing centos on a usb flash drive. Perhaps a 4GIG. I dont need X or anything on this drive so installing should fit just fine. Are there boot issues with these flash drives? I'll be using a newer motherboard so the motherboard should be able to boot USB. Does this work? Have others done anything with flash drives? I am wanting this flash drive to be the ONLY drive in the computer. Kind of a dedicated machine running multiple RS232 multiport cards. Thanks, Jerry

Monitor not put in powersaving mode
by Kai Schaetzl 20 Aug '07

20 Aug '07

I notice that CentOS 5 only blanks out my screen, but doesn't set it to powersaving mode (the power LED stays blue instead of going yellow). I think I saw this on CentOS 4 as well, but I had a CentOS 4 console machine only for a short time back then and after that only remotely used ones. Now I have one fully running workstation with X under CentOS 5 and would like to fix that. This also happens in run-level 3, so it's not specific to the X-Server or desktop manager.
