Hi folks,
ok, I ran into the following problem: In my box I have an ATAPI CD-ROM,
which is the only (E)IDE device I have (drives are SCSI). Recently, it's
been acting up a bit and starts "slipping" when reading certain CDs
(among them the official RHL 5.2 CDs... <sigh>), i.e. it tries to spin
up and fails (as the CD slips and doesn't get up to speed).
While I know how to fix this mechanical problem, this situation has
presented me a Linux problem as well: If the "slipping" occurs during a
mount, the mount fails (obviously) - and screws up the whole CD mounting
royally. After a mount that failed, I can no longer mount any CDs - I
get messages saying that "/dev/cdrom is mounted already or mount point
busy". Of course, I tried several different mount points - no luck. I
also had a look at /etc/mtab, but no hint of cdrom (or hdc, which cdrom
points to) in there. Is there any way of "resetting" this short of
rebooting? So far, only a reboot would remedy this situation (even
dropping to runlevel one didn't help) - which is highly annoying.
Any ideas?
Thomas
P.S.: I've heard of "lsof". Problem is: It doesn't work on my system -
I'd have to recompile the kernel, as after the last recompile I
forgot to copy "System.map" (which isn't mentioned in the user
manual, grrr....) and I don't have the correct one anymore... :-(
