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
