lost interrupt?

lost interrupt?

[lawyer]

hello everyone!
After I started my linux system with two harddisk,I move the second
harddisk</dev/hdc> away.
when I mount the no existing device </dev/hdc9> on my file system ,there is
something wrong!
kernel uninterruptedly display "mount :lost interrupt !",and we can't kill
mount process.
who can tell me how to repaire mount program? there are some patch to do it?

hi,
well it isn't custom to remove ide-devices wheile the system is running (at
least that's waht you did as I understand it).
Have a look at your process-table by typing; ps aux | grep mount
this will give you a line wiht a lot of data and a Letter-cde on the right
halve of the screen (capital letters R S W Z).
If it reads Z it's a zombi-process and you can't kill it.
The best way to go is to find the appropriate output format in the ps
manual and find the parent-process of your mount process.
If you found it, kill it.

If by any change this is init itself, your fucked and a a complate reboot
is ABSOLUTELY NECESSARY!!!

good luck,

I am sorry for my poor English!
yes you are right.I remove ide-devices while the systemis running. but I do
nothing mount action, only when starting the kernel recoginized the two
ide-devices.

Re: lost interrupt?

[Andor Demarteau]

look in your /etc/fstab
if there is a line mounting the /dev/hdc9 partition in it without the
keyword nonauto on it, it is automagically mounted during bootup.
May I advice you not to remove ide-devices from your system wehn it's
running unless you have a speical harddisk-reck for it which support
hot-swapping of IDE-disks.

Re: lost interrupt?

[lawyer]

I have looked in /etc/fstab and /etc/mtab ,finding nothing about /dev/hdc.
I must say that /dev/hdc9 wasn't mounted really!

Re: lost interrupt?

[Andor Demarteau]

well, removing an ide-device and then trying to mount a partition on that
removed disk is bound to cause troubbles anyhow.

did you look at the ps output like I suggested to see the status of your
mount process (which as I understand it hanged upon you trying to mount the
/dev/hdc9 partition)?

So far as I know you CANNOT remove a standard IDE device while the
system is running and hope things still to work. Don't forget that the
HD you removed was on the same bus as the other HD left in place most
likely; the message you receive from mount might very well speak your
HD that's still in place. Please anyone correct me if I'm wrong, but I
do not believe that neither regular PC hardware nor the linux kernel
were ever designed to face such situations...

Re: lost interrupt?

[Andor Demarteau]

hi,
your correct. Only if you have a hd-rack you can hotswap ide-disks (if the
rack suppots it anyway).
Any other removal of ide-stuff should normally give trouble or crash your
box.

Re: lost interrupt?

[L. C. Robinson]

Not to mention the significant risk of permanent damage to
hardware that was not designed for hot plugging.  Before hot
plugging stuff, you should make sure that the interface standards
specify that it can withstand such abuse, as, for instance,
serial ports can: even many of the external ports on the back of
your computer are risky candidates for this sort of thing (you
should query or search an appropriate newsgroup for the details
of what will work safely -- this whole thread is off topic).
Even so, you can't expect to remove or install, say a serial
mouse, and have the thing work automatically, without
reconfiguration (in some cases, there are programs that can
automagically reconfigure hardware, usually only during bootup).

People buy MicroShaft for compatibility, but get incompatibility and
instability instead.  This is award winning "innovation".  Find

Re: lost interrupt?

[lawyer]

yes I hava run <ps aux|grep mount> ,nothing returned! after started ,I did
some mount,but I did umount too,before removing!

some program of mount:
...
fd=open("/dev/hdc9",...)
if(fd<0) return 0;
if(lseek(...)!=1024||( read(fd,(char *) &sb,sizeof(sb)) ) != sizeof(sb))
...
the program can open "/dev/hdc9" correctly, but,when read(...) ,because I
remove the ide-disk, kernel cann't find the device ,and recognizes this as a
time-out or other mistake and reports "mount : lost interrupts!"

Re: lost interrupt?

[Andor Demarteau]

let's call this thread finished and let the final point be that ide-devices
can not be removed during system-online.
In that respect I can't help you and only give you the advice to poweroff,
place the disk back if needed and startup again.
regards,
