Putting "blacklist" above "devices" seems to work: defaults { polling_interval 5 getuid_callout "/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/%n" no_path_retry fail user_friendly_names no flush_on_last_del yes fast_io_fail_tmo 5 dev_loss_tmo 30 max_fds 4096 } blacklist { wwid "*" devnode "^sd(a|b)[0-9]" } devices { device { vendor "COMPELNT" product "Compellent Vol" no_path_retry fail } } multipathd restart: Dec 10 16:32:19 tulhv2p01 multipathd: --------shut down------- Dec 10 16:32:19 tulhv2p01 multipathd: path checkers start up No more syslog pollution!

Hello
I have a Host with LocalOnHost storage only.
Trying to blacklist the local disks from multipath:
PV VG Fmt Attr PSize PFree /dev/sda1 HostVG lvm2 a-- 8.18t 0 /dev/sdb4 HostVG lvm2 a-- 1.64t 24.00m
As you can see we need to blacklist these devices:
36b8ca3a0ea18e4001a95ba4832bcb7ea 36b8ca3a0ea18e4001a95b9f82df5609b
scsi-36b8ca3a0ea18e4001a95b9f82df5609b -> ../../sda scsi-36b8ca3a0ea18e4001a95b9f82df5609b-part1 -> ../../sda1 scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea -> ../../sdb scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part1 -> ../../sdb1 scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part2 -> ../../sdb2 scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part3 -> ../../sdb3 scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part4 -> ../../sdb4
After making blacklist changes, you can see in "syslog_errors," multipathd does not like my blacklist syntax.
Do you see errors in the multipath.conf file?
Thanks Doug
