• BZ 1622700 [downstream clone - 4.2.6] [RFE][Dalton] - Blacklist all local disk in multipath on RHEL / RHEV Host (RHEL 7.5) Feature: Blacklist local devices in multipath.
Reason: multipath repeatedly logs irrelevant errors for local devices.
Result: Local devices are blacklisted, and no irrelevant errors are logged anymore.
What defines a local disk ? I'm using a SAN on SAS. For many peoples, SAS is only for local disks, but that's not the case. Will other 4.2.6 will detect that ?
We don't have any support for SAS.
What you call SAS is any block device we might want to attach directly and let oVirt manage. I was doing the same thing on old HPE hardware, using old smart array controlers. I gave the raw device to ovirt. After an upgrade, it fails as it was blacklisted. I need to add it to the blacklist exceptions: cat /etc/multipath/conf.d/enable-sas.conf blacklist_exceptions { protocol "cciss" } I think your default rule is quite hard, and can brake many existing setup: multipathd show blacklist ... protocol rules: - blacklist: (config file rule) .* - exceptions: (config file rule) (scsi:fcp|scsi:iscsi) (config file rule) cciss <-- mine
