>From the data I can see all 6 multipath disks are set to failover mode. Which in this special case is done because some implicit logic in the multipath-tools detected that the scsi controller supports ALUA queries and those returned that host0 has all disks in active state. So all IO is going through that controller. The scsi disk devices seen through the other controller (host1) are only in standby.
The boot dmesg reports inconsistencies in the ext4 filesystem on dm-6 which due to a (normally harmless) error message before can be translated into mpath1-part2. Not sure, but on the system you gave me access to the only alias with data was mpath0. So that may be a potential problem or just a different config. And what cannot be seen is whether maybe the installation+reboot had maybe left the filesystem in a bad state. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1462530 Title: multipath errors on vivid and wily kernel? Status in linux package in Ubuntu: Confirmed Bug description: Oleg and I got changes into curtin to fix bug 1371634. So that now we can boot into multipath iscsi devices on power. It seems to go well enough with trusty+hwe-u, but when trying vivid, I am seeing errors.
