I am trying to mount a a Magneto Optical WORM drive, mechanically it is a 2.6 Gb, 1024 Bytes/Sector, 5.25", Verbatim Media, The disk was created under OS-2.
I am using CentOS 5, and have tried mounting the disk as msdos and as vfat and get superblock errors among others.
what filesystem type did OS-2 use? is there an add on to CentOS that will support the filesystem?
I am trying to access a Magneto Optical disk written under OS/2 hpfs filesystem. I cannot locate a dang thing about support of CentOS for OS/2. I found a module for Linux OS/2 support that dated back to 1993, have no idea how to compile it, used alien to create an RPM package, said compiled succesfully, still can't mount the drive (/dev/sdb) with filesystem type -t hpfs. Can anyone out there help me, or does CentOS just not do this?

MP3 Audio Decoder plugin not found.
K3b could not load or find the MP3 decoder plugin. This means that you will not be able to create Audio CDs from MP3 files. Many Linux distributions do not include MP3 support for legal reasons.
Solution: To enable MP3 support, please install the MAD MP3 decoding library as well as the K3b MAD MP3 decoder plugin (the latter may already be installed but not functional due to the missing libmad). Some distributions allow installation of MP3 support via an online update tool. Installed libmad without success........
I need information about the capabilities and state of the disk...specifically, if it's rewritable (capability) and if it's currently blank (state). Currently, I'm using the output of hal-device to give me that information. The problem is, hald doesn't update the information in response to a burn event... this is a problem, because if a burn a blank disc, hal-device still lists it as blank...and if I blank a disk, hal still lists it as non-blank.
Is there a method to force HAL to update a device, or is there a way to query the disk/drive directly to find out if the disk is blank and rewritable? Or even a method to determine if a disk is blank or not? Additionally, this is for a CD-burning application... so I'm intentionally trying to avoid anything hacky like ejecting the CD and reinserting it... anything of that nature.
how to get a bash script to automatically launch when the optical drive mounts a disc, any type of disc - DVD, CD, data, etc. It seems like such a simple task but after weeks of searching I have yet to find a workable solution.

After replacing the the cdrom drive with a similar model known to work well I could not get it to mount. I then tried to move important files to usb to try a fresh install. The usb stick flickered when I put it in, but it didn't mount. Same behaviour as the cdrom, the light goes on when I turn on the computer, but once I'm logged in I can't access the cdrom.
I have tried multiple variations of playing with fstab and trying to mount things in terminal to no avail. I just can't get Ubuntu to recognize the usb or cdrom even though their lights go on when I first try to use them.
Finally got FC8 installed on new machine, and now it won't mount CDs/DVDs - didn't change anything in BIOS, CD/DVD drive is only thing on the IDE controller (HD is SATA) so is it likely a driver issue? FC8 seemed to have correct (or at least working) drivers for LAN, audio, SATA, etc.
View 1 Replies View RelatedI'm trying to get a script to run whenever an optical disc is mounted by the system but can't get it to work. I'm running Fedora 12 64bit and the drive is SATA device sr0.
Following online guides, I created a new rule file called '10-my.rules' in '/etc/udev/rules.d' which contains the following:
Code:
KERNEL=="sr0", RUN+="/usr/local/bin/myscript"
But nothing happens when a disc is mounted. The script itself runs fine manually and is clearly evident when launched so the problem must be the rule file. I've tried changing the name of the rule file in a few incremental steps from 10-my.rule to 99-my.rule to no effect.
I've gathered some information about my optical drive using the udevadm tool.
Here is the result of an info query:
Code:

N: sr0

I dont know when k3b stopped working but have just gone to burn a disk and when opening it tells me
Quote: No optical drive found. K3b did not find any optical device in your system. Solution: Make sure HAL daemon is running, it is used by K3b for finding devices.
I can boot from cd and can mount cds from within Slackware but for some reason k3b insists that i don't have a drive.
I see to be having a problem with the SCSI disk that I'm trying to install. The computer that it is attached to was Win XP and SCSI worked fine. When we changed the computer over to Fedora 10, SCSI was being read by the computer but is not accessible.

This small/slim external drive has two USB cables, one for power and one for power/data. So, I plugged the power cable into my nearby Windows desktop computer and just the power/data into the Ubuntu PC.
View 6 Replies View RelatedThe system is fc12 with a scsi pci card. There are 4 disks on the scsi chain, properly terminated. At boot time the system does not recognize the 4th drive. It creates a /dev/sdh entry, but the individual partition entries are not created. fdisk /w creates the /dev/sdh* partition entries. After that the drive is recognized by the system.
Is there record of the device scan activity? What could cause the boot process to identify the drive but stop short of identifying the partitions.

My dmesg shows :
I am developing for a Linux based device for which the HOT PLUG option is deactivated. As part of optimizing the code, we also don't want to create device files for unused devices. We understand that both USB attached and fixec SCSI hard disks would create device files like /dev/sda,/dev/sda1 /dev/sdb, /dev/sdb1 etc. Is this understanding correct?
In the case of USB attached SCSI devices, would driver create this device file entry? How is it created? Can somebody please tell me how it is being created automatically. In case I attach a fixed SCSI hard disk before boot up(and create device file /dev/sda1), would USB SCSI device driver create device files starting from /dev/sdb, automatically.
I have three disk in my system. One SATA (250GB) and two SCSI (73GB) disks. The Two SCSI disks were installed originally and RHEL3 is installed on it. The SATA disk is installed a few years later with RHEL5. As you can see below, the boot sector is still on one of the SCSI disks (sdb1).
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 236545184 15259760 209075624 7% /

How I can move the boot sector from the SCSI disk (sdb) to the SATA disk (sda) without losing data and without re-installation?
I currently have the following:-
Optical Out from my TV into the SPDIF / Optical In on my PC
Optical Out from my PC into my Sony 5.1 Theatre Kit
The audio from the PC comes through ok when listening to music and movies. But unfortunately I can figure out how to enable the audio passthrough from my Tv so that the audio comes out of my theatre kit. In Sound Preferences, the hardware is set to 1 Output / 1 Input [Digital Stereo (IEC95 Output + Digital Stereo (IEC95 Input]. When I click on the audio tab, the Input Volume is at 100% and the Input Level is moving in conjunction with the audio coming from the Tv.
I saw it mentioned in another thread to install Gnome Alsa Mixer which I've done, it seeems to identify the audio chipset as Realtek ALC882, the motherboard is an Abit AB9 Pro. Hopefully I'm missing some config somewhere or there a box I should be ticking but I just can't find it.
Suppose during a script execution I am attaching one or two new disk having different vendor id to host machine, how do I know which disk corresponds to which file in /dev/ directory? i just want to perform some operation on those device from some script, how will i know which file in /dev directory correspond to which disk(having same size but different vendor id).
View 1 Replies View RelatedSo I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.
i m facing same error in most of the HCL servers. the problem is that it throws error while booting and sometimes not throws error. the error is :-

In my understanding, the way /proc/scsi/scsi gets populated, /proc/paritions also gets populated in the same fashion. i.e. the description for first entry of /proc/scsi/scsi can be seen in the first entry of /proc/partitions and same for rest.
So, With this assumption, in my project, I used to relate first entry of /proc/scsi/scsi with first entry of /proc/partitions to get its total size and same for all entries.
But, I observed some differences in following scenario, where
1) The first 4 entries in /proc/scsi/scsi are SAN luns attached to my system and for which the actual device names in /dev/ are sda,sdb,sdc and sdd.
2) The last 4 entries are the internal HDDs on same system. In /dev/, their respective device names are sde,sdf,sdg & sdh.
(Output attached at end of the thread)
But in /proc/partitions, the device order is different.
You can see their respective sizes in /proc/partition output as well.
So, my question is, in this particular scenario, I can't relate the first entry of /proc/scsi/scsi with first entry of /proc/partition. i.e. scsi0:00:00:00 is not /dev/sde, because it is actually /dev/sda.
It seems that my assumption is wrong in this scenario.
Is there any way or mechanism to figure out actual device name for an entry in /proc/scsi/scsi in /dev/ directory?
How can my application should relate /proc/scsi/scsi entries with their respective device names and sizes?
When I enter "cat /proc/scsi/scsi" I'm returned with "cat: /proc/scsi/scsi: No such file or directory". I've tried this on two different installs on two different machines.

Ok I just installed my 1.5 TB drive. I used Gparted to format it as ext3 . why is it saying that the size is 1.36TB with 22.12Gib used and 1.34 TiB unused. How is it that I used the drive and all I did was install it. how should I reformat/format it.? I'm not putting an OS on it. Just media.
Currently I have the file system as extended and then under it its ext3
