Re: umount - URGENT - solved (again)
It seemed to me that I already expressed may thanks, but apparently it didn't hit the right person. So once again: among lots of pieces of advice (I remain grateful to everybody who wanted to be helpful) I got two answers that really solved my problem: 1) Dave Sherohman wrote: lsof should give you the pid of any processess using it. 2) [EMAIL PROTECTED] wrote: Try man fuser and learn how to find out which process is still blocking the device. Thanks again! Blazej I know it is a bit late, but I havent read my mail since than. This is in reply to: Dave Sherohman wrote: Wayne Topa said: Try a paper clip, strightened out, and inserted into the little hole in the front of the CDROM drive. Works on the 3 I have. I thought you weren't supposed to do that while the system is powered up. Something about possibly damaging the hardware. Is that no longer a problem? (Or did I just image the whole thing...)
Re: umount - URGENT
A better instruction would be to umount /dev/cdrom, since this will almost always be a symlink pointing to your cdrom device. Far more systems use /dev/cdrom for their cdrom devices than use /dev/hdd, because this includes nearly everybody with /dev/hdd, /dev/sdd, /dev/hdsomeotherletter and /dev/sdsomeotherletter as the cdrom device. that's great, but what if the problematic cd happens to be the second cd device? /dev/cdrom won't help if that's the case, so using /dev/thedevice is a better choice, IMHO, if you know the device you want to umount. -- dave wiard [EMAIL PROTECTED]

Use in every console 'cd' to take the user to 'the home'. CD insn't anybodys's home at your computer? Then using 'su' umount it by giving 'umount dev/hdd' (assuming that your cd is at hdd as mine...)

if anyone has a shell open that is is within the directory structure of the cd then it will report as being in use when you try to unmount it. make sure every account logged on to the machine is in a different directory (ie home directory) and you should be able to get the cd out On Fri, 7 Jan 2000, Blazej Sawionek wrote: I've just fallen into serious trouble: can not umount my CD-ROM - it is reported as beeing used.

Try to see, if there is someone in some other console using it anyway. If 'anybody' is cd'd on your cd's directories you cannot umount it I think.

If it crashes sometimes I can't even turn the power off on it, I end up having to unplug the stupid thing to reset it!

Gary Hennigan said: My SGI is entirely soft button. If it crashes sometimes I can't even turn the power off on it, I end up having to unplug the stupid thing to reset it! That's excessive, of course, but I'd like to see something along the lines of the option on most ATX BIOSes to have a manual poweroff require you to hold in the power button for 4 seconds. This prevents you from absent-mindedly turning it off at a Bad Time, while still allowing a 'manual override' if your OS crashes. The same concept applies to disks, etc. (I don't like to think about all the times I've switched floppies, tried to mount the new one, and discovered that I forgot to unmount the previous disk...) The problem here, though, is that if something manages to crash the BIOS (or internal drive circuitry) controlling the sticky button, you're SOL again, just like with your SGI. But those sorts of things tend to not crash, so I doubt that it's a major problem. -- Geek Code 3.1: GCS d- s+: a- C++ UL++$ P L++ E- W--(++) N+ o+ !K w---$ O M- !V PS+ PE Y+ PGP t 5++ X+ R++ tv- b++ DI D G e* h+ r++ y+
