[Bug 927540] Re: multipath ignores blacklist in multipath.conf
That's actually a good point Lukasz, one that I assume folks get by reading the multipath guide first. https://help.ubuntu.com/12.04/serverguide/multipath-devices.html Whenever you use blacklists, in either lvm or multipath, you must update the initramfs so those config files are copied to the ramdisk, otherwise you can get a race that makes it look like your blacklist is having no effect. # update-initramfs -u -k all should do it. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/927540 Title: multipath ignores blacklist in multipath.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/927540/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 927540] Re: multipath ignores blacklist in multipath.conf
This is not a bug of multipathd. I gues that you are using DELL MD3xxx multipath installer. This install script provide new initrd that have one significant change - add multipath.conf (the same as they add in standard /etc) in initrd environment. So - at the initrd stage when lvm starts (with default lvm.conf @initrd) they links local filesystem lvm to multipath device. When chroot phase is in time your config defined in root /etc/multipath.conf can't remove PERC multipath dev because they are already in use by root fs. Solution - please swap initramfs (@ /boot/..) to the original (it's now rename) and at the initrd stage no multipath devices of PERC will be created. You multipath.conf in rootfs /etc/multipath.conf are OK). regards LS -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/927540 Title: multipath ignores blacklist in multipath.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/927540/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 927540] Re: multipath ignores blacklist in multipath.conf
That devnode line is actually part of the default in memory config, see libmultipath/blacklist.c#setup_default_blist. So try dropping that. Just try and keep you multpath.conf as simple as possible, to even *one* directive, test and record, then iterate until you start to see it break. It's best to stop multipath-tools altogether and just multipath -F multipath -v4 until you find the breakage. Record the logs the entire time using redirection or 'script' and attach your results to this issue.

[Bug 927540] Re: multipath ignores blacklist in multipath.conf
multipath supports POSIX regexp: libmultipath/regex.c so you do need
the . to inform the wildcard what it's matching against e.g. (1+ more
characters).
There are also examples in the multipath.conf.defaults file that provide
examples
of regexp like:
# device {
# vendor HP
# product LOGICAL VOLUME.*
# getuid_callout /lib/udev/scsi_id --whitelisted
--device=/dev/%n
and
# device {
# vendor DGC
# product .*
# product_blacklist LUNZ
If you want to wildcard an entire field, leaving out the dot works, but when you
start matching within strings, you need to specify what it is you're matching.
#blacklist {
# devnode ^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*
# devnode ^hd[a-z]
# devnode ^dcssblk[0-9]*
#}
You could try a dramatically simplified multipath.conf like this:
blacklist {
device {
vendor *
product *
}
}
blacklist_exceptions {
device {
vendor NETAPP
product LUN
}
}
The continue configuring your SAN under a new devices{ device {} } section.
In my case I just take the defaults. to prove to yourself that this works,
stop multipath server, flush all paths (multipath -F), and then change
the config file to include only the blacklist (exclude everything), run
multipath -v4 and observe.

So it indeed blacklisted everything. and multipath -ll produces nothing.
Once I add my SAN to the blacklist exception block everything functions
as expected.

[Bug 927540] Re: multipath ignores blacklist in multipath.conf
At the moment i've no Ubuntu 12.04 Testmachine at hand. ASAP I'll try
your suggestions. But I don't think, that this is the problem. My Dell
Controller has the following wwid:
36782bcb070070100166a7a1640a66db2 dm-0 DELL,PERC 6/i
size=136G features='0' hwhandler='0' wp=rw
In the Blacklist that wwid is explicitly listed:
blacklist {
wwid 36782bcb070070100166a7a1640a66db2
...
Although the Controller is still listed.
In the Red Hat Documenation (http://docs.redhat.com/docs/en-
US/Red_Hat_Enterprise_Linux/6/html/DM_Multipath/device_type_blacklist.html)
they use also * as wildcard for multiple matches:
blacklist {
device {
vendor IBM
product 3S42 #DS4200 Product 10
}
device {
vendor HP
product *
}
}

[Bug 927540] Re: multipath ignores blacklist in multipath.conf
I think blacklist device maching is expanded as a regex and not as a
glob, thus the * will not provide a match. Can you try the following
change.
Replace:
device {
vendor DELL*
product PERC*
}
With:
device {
vendor DELL.*
product PERC.*
}
Also if you could paste the output from
$ sudo udisks --dump
It would help debug this issue, I am not on the Ubuntu team but I am
trying to track down an issue that may be related to this.
