** Description changed: If a system is not installed w/ multipath support (i.e., no disk-detect/multipath/enable=true), the /etc/multipath.conf file is not installed. If an user later installs multipath-tools-boot, it will enable the udev rules for multipath support. - Those rules don't handle disk devices w/ spaces on their names/uuids/models very well.. + Those rules don't handle disk devices w/ spaces on their names/uuids/models very well.. That's because of udev's SYMLINK command using spaces to separate multiple links, and the kernel sysfs/dm informing \x20 instead, which is not correctly interpreted by some commands, resulting in file not found errors, for example. Thus, the system fails to boot. There's no problem, however, if user_friendly_names is enabled in multipath.conf (which is enabled in the default multipath.conf from the installer, if it has multipath enabled). Notice it's an acceptable case to install w/out multipath support, and enable it later for booting. Disk devices w/ spaces in naming is not common over SAN/storage systems, but that happens often for conventional disks; for example: - IBM IPR ( IBM IPR-0 5DB6F40000000080 ) - - IBM VDASD ( AIX VDASD 00c96f0700004c000000014bb8e713f0.14 ) + - IBM VDASD ( AIX VDASD 00c96f0700004c000000014bb8e713f0.14 ) - QEMU HARDDISK ( QEMU QEMU HARDDISK <serial> ) So, please, is it possible to ship the default multipath.conf (e.g., from installer) w/ multipath-tools-boot? For users not to their systems failing to boot after installing multipath-tools-boot manually, after a non-multipath install. + + Related bugs: + * bug 1371634: block devices appear twice
