I backed up my home directory and files, so when I installed 9.0 I HAD INSTALL FORMAT THE DISKS CLEAN. Point of telling you this is under 7.3 I HAD NO CDROM PROBLEMS so I know the hardware is fine! ;-) UPDATE! in Gnome I went into Start Here / System Tools / X CDroast Cd Writer and stepped through its configuration. Once I did that, the CDROM mounted perfectly. Now it seems to mount fine from command line or from the Disk Manager tool, for now anyway.... What happened to fix it?????????????? I noted this "lsmod" change after doing the xcdroast setup:
Before:
scsi_mod 110488 4 [ide-scsi st aic7xxx sd_mod]
After:
scsi_mod 110488 6 [sg sr_mod ide-scsi st aic7xxx sd_mod]
^^ ^^^^^^
Weird thing is I'm sure I tried this manually after comparing to my 9.0 install
at work, but it made no diff. xcdroast did something to fix it.
Spoke too soon - after REBOOTING Linux, it was back to same error on mounting the CDROM. Still need help fixing this issue. Found out from checking in CD-Writer (a Gnome Utility) that my CDROM is /dev/scd0 not /dev/hda ! When I specify mount /dev/scd0 /mnt/cdrom -t iso9660 then is mounts fine! So the question is why did the Linux installer chose to use /dev/hda as my CDROM such as in the grub.conf ??? this is more a bug of the installer (anaconda).. I am reassigning.. Did you install from CD, and if so, which device did you install from? I installed from the same CD device as the one I have trouble mounting. Specifically it should be /dev/hda but I can only mount it as /dev/scd0 It is a CD-Read/Write device. I only have this one CD device in my PC. Yes I installed completely from a 3-CD set. I'll assign this to be looked at. The reason the device is /dev/scd0 after you reboot is that ATAPI CD burners look like a SCSI device to the kernel. If you want a quick workaround you will want to move the symlink for /dev/cdrom to point at /dev/scd0. Michael thank you for the workaround suggestion, however I did in fact try that already (changed the symlink /dev/cdrom --> /dev/scd0 rather than /dev/hda, and yes mounting /mnt/cdrom worked fine then) but for some odd reason, after I rebooted, the system had *automagically* changed that symlink /dev/cdrom to point back at /dev/hda ! ?:-( What does your ide setup look like in general (which devices are what drives, etc.)? Closing, lack of response. |
Description of problem: cannot mount cdrom on new install of Red Hat Linux 9.0 Version-Release number of selected component (if applicable): Red Hat Linux 9.0 (kernel 2.4.20-8 scratch install) and Red Hat Linux 9.0 (kernel 2.4.20-9 and all errata updates) How reproducible: Every time. Steps to Reproduce: 1. insert cdrom 2. type the mount command 3. get error shown above Actual results: [root@boaz rpm]# mount /dev/cdrom /mnt/cdrom -t iso9660 mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) [root@boaz rpm]# [root@boaz rpm]# mount /mnt/cdrom mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted file systems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) [root@boaz rpm]# Expected results: should have /mnt/cdrom mounted.
