[linux-lvm] vgscan & CDROM

[linux-lvm] vgscan & CDROM

[Chris Osicki]

Hi 

I seam not to be able to convince vgscan to let my cdroms alone.
In the file /etc/lvm/lvm.conf I have this filter:

[ "r|/dev/cdrom.*" ]

when I run vgscan -v -v I see the following:


      /dev/cdrom1: size is 31244 sectors
  /dev/cdrom1: read failed after 0 of 2048 at 0: Input/output error
      /dev/cdrom1: size is 31244 sectors
      /dev/cdrom1: No label detected


I tried other variants of this filter without luck.
On the laptop I'm writing this message on it took several minutes for
vgscan to finish. On another PC it doesn't take that long but is
annoying. How do I convince vgscan not to scan those devices?
I tried also such a filter as test:

[ "r|/dev/pty.*" ]

it didn't work either.

I'm using 

  LVM version:     2.01.09 (2005-04-04)
  Library version: 1.01.00-ioctl (2005-01-17)
  Driver version:  4.4.0

I would be very thankful for any help.

Regards,
Chris

Have you tried it?

This doesn't work for me.

Does anybody know the solution?

Try it without the dot:
[ "r|/dev/cdrom*" ]

The /dev/cdrom* devices don't usually contain a dot, unless you've
changed your udev rules. Judging from your output of `vgscan -v -v',
however, it seems that you haven't done so.

Hope it helps,

   [ "r|/dev/cdrom*|"] maybe ?

You can even be more restrictive/explicit:
filter = [ "r|/dev/cdrom*|", "r|/dev/cdrw*|", "r|/dev/dvd*|",  
"r|/dev/hd[ab]|" ]

(my drives are /dev/hda and /dev/hdb)

Works for me.

but my dev is /dev/cdrom if yours is /dev/cdrom1 try filter = 
[ "r|/dev/cdrom1|" ]

Even if you put an empty CD-ROM or DVD into the drive and run
vgscan -v -v -v 2>&1 | grep cdrom ?

Then we must be using different lvm versions.

OK, that are my filters now:

    filter = [ "r|/dev/hdb|" ]
    filter = [ "r|/dev/hdc|" ]
    filter = [ "r|/dev/cdrom|" ]
    filter = [ "r|/dev/cdrom1|" ]
    filter = [ "r|/dev/cdrom*|" ]
    filter = [ "r|/dev/cdrom.*|" ]

I have two DVD writers /dev/hd[ab] /dev/cdrom and /dev/cdrom1 are
softlinks to them.
vgscan still access them both.

Could anyone who knows the code comment on this?
Looks like I will be going to read it.

Thanks,
Chris

i tought the syntax was:
filter = [ "r|/dev/hdb|", "r|/dev/hdc|", "r|/dev/cdrom|" ]

you should not need the last 3, since "r|/dev/cdrom|" being a regexp
matches all of them.


btw, i believed "sysfs_scan = 1" was enough to skip cdroms

Hi Luca

I tried your idea:


grep cdrom /etc/lvm/lvm.conf
     filter = [ "r|/dev/hdb|", "r|/dev/hdc|", "r|/dev/cdrom|" ]

vgscan -v -v 2>&1 | grep cdrom

      /dev/cdrom1: size is 31244 sectors
  /dev/cdrom1: read failed after 0 of 2048 at 0: Input/output error
      /dev/cdrom1: size is 31244 sectors
      /dev/cdrom1: No label detected
      /dev/cdrom: size is 4 sectors

Regards,
Chris

i don't have the code at hand, but, if they are regular expression
"/dev/cdrom*" would match
/dev/cdrom
/dev/cdromm
/dev/cdrommm
/dev/cdrommmm
and so on..

see man 7 regex

Re: [linux-lvm] vgscan & CDROM

[Chris Osicki]

Hi

It is hard to believe I'm the only person for whom the vgscan
filtering doesn't work as expected.
Would anybody of you do a small test for me and send the result:

    put an empty CD/DVD into the drive
    vgscan -v -v -v -d 2>&1 | grep cdrom
    lvm version

Provided your CD/DVD has a "cdrom" in the devicefile name.

Please note if there is no media in the drive you won't see cdrom
if you run vgscan, vgscan -v or vgscan -v -v

Thanks for your time.

Regards,
Chris
