I'm planning an upload in a day or two and I want to fix this bug. I have taken
your patches and cooked up something.
While testing, I realized that it looks like udev itself is taking care of
activating/de-activating iscsi devices.
Now I can still go ahead with the patches applied and upload it or else drop
the patches and offload that task to udev. Comments ?
If udev umount lvm devices, then it is ok (drop this patch). Maybe lvm
maintainer knows better who should umount these _netdev devices ?
I can test your new upload and tell you if I see any issue
Thank you very much

Hello,
I have a similar patch for this issue (but the first in this bug seems
fine too), so I'm not attaching my patch, but yes a complementary patch.
I think unmounting lvm filesystem is necesary. This patch, umount LVM
filesystem from iscsi disk:

We (as debian user) have another problem with lenny and iscsi + lvm +
multipath (should I open another bug?). I try to explain it here:
# pwd
/etc/rc6.d
# ls -1 *multipath* *iscsi* *lvm*
K20multipath-tools
K80umountiscsi.sh
K81open-iscsi
S50lvm
S50lvm2
Suppose I have a pv in iscsi lun, and over it a vg, who has a lv.
So if multipath is down, how umountiscsi is capable to unmount lvm volume?
My server hangs forever when is rebooting or shutting down. With sys+rq W
debian said to me there is a process lvchange who is blocked. I can read
in redhat issue tracker [1] about similar bug in redhat systems.
Is it possible to "full" support lvm inside iscsi luns ?
Any help is apreciatte.
Thank you.
