This is not a bug. Please review the --homehost= option in the mdadm(8) man page.
In a nutshell: Your RAID devices store the hostname in the superblock, so that when "mdadm --assemble" is called, it only assembles RAID devices that belong to the running host. (The rationale is that if you, for some reason, have hooked up a RAID device from some other host, and mdadm auto-assembles that, Bad Things(tm) may happen. It's a safety feature for that very rare circumstance.) Either update the homehost setting in the superblocks, or change the HOMEHOST parameter in /etc/mdadm/mdadm.conf . (If it's set to "<system>", which it probably is, mdadm will substitute the system's current hostname.) -- raid array wont work after Hostname change https://bugs.launchpad.net/bugs/325827 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
