[linux-lvm] lot of scsi devices bug

[linux-lvm] lot of scsi devices bug

[German Staltari]

Hi, this is maybe a udev bug, but it affected me when I was creating a 
lv in a cluster, so it could help some with this configuration.
When I added some scsi disk (SAN) to the cluster nodes (more than 64 
SCSI devices),  udev created the device node for capi20 instead of sdbm. 
This produced  a bad behavior in lvm when I was trying to create the 
vg's and lv's, it started to give errors like:

Error locking on node node-06: Internal lvm error, check syslog
Error locking on node node-05: Internal lvm error, check syslog
Error locking on node node-04: Internal lvm error, check syslog
Error locking on node node-01: Internal lvm error, check syslog
Error locking on node node-02: Internal lvm error, check syslog
Error locking on node node-03: Internal lvm error, check syslog
Failed to activate new LV.

When I commented out this lines

SYSFS{dev}="68:0",              NAME="capi20"
SYSFS{dev}="191:[0-9]*",        NAME="capi/%n"
KERNEL=="capi*",                MODE="0660"

in /etc/udev/rules.d/50-udev.rules, everything worked again.

I hope this could help,
