[Bug 271732] New: initrd mounts individual elements of a RAID-1 array if mount-by-UUID is used
https://bugzilla.novell.com/show_bug.cgi?id=271732 Summary: initrd mounts individual elements of a RAID-1 array if mount-by-UUID is used Product: openSUSE 10.2 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Critical Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: teheo@novell.com QAContact: qa@suse.de CC: hare@novell.com, jeffm@novell.com, kasievers@novell.com Each element of a RAID-1 array apparently has the same image as the array itself. It seems initrd (or udev in it) doesn't care whether a partition is a member of a RAID-1 array or not. During boot, for some reason, initrd mounts one of the elements after loading the disk driver but before loading md. This makes md fail to claim the partition and run in degraded mode. After loading md, initrd mounts md as root again (probably on top of the previous mount). Last night, while trying to determine what's going on (as I wasn't able to add back one of the element into the array), I updated the kernel and the filesystem exploded. I'm still not sure how things went down exactly but after a while I was left with half destroyed filesystem. Anyways, recognizing a member of RAID-1 array as independent filesystem is inherently dangerous. It's also likely that the same problem exists for mount-by-volID. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

If I had to guess, I'd say what's happening is that the udev rules for UUID=/LABEL= are establishing the links in /dev/disk/by-{uuid,label} and md isn't getting started. If md were started, the two constituent disks would be locked out. Also, I suspect that the uuid/label on the md device would override the original ones. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

It is hopefully fixed for openSUSE 10.3 by sending additional "change" events. The udev version in openSUSE 10.3 has special rules to handle MD-devices. There have been improvements in libvolume_id which recognize md devices more relibly. Tejun, can I log into the box, or give you instructions how to test the new version? On your box, what hat does: /lib/udev /dev/sd* (raid member) print? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
