From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: The permissions on the default volume groups are 600 root:root, and should really IMHO) mirror sd* permissions: 660 root:disk. Specifically, this makes amanda-client die and causes amanda-based backups not to run. Version-Release number of selected component (if applicable): udev-039-10.8.EL4 How reproducible: Always Steps to Reproduce: 1. Set up a RHEL 4 host with LVM (the default) 2. Set up a backup set including a RHEL 4 host (make sure a hole is in the fw) 3. Run amcheck Actual Results: Amanda Backup Client Hosts Check -------------------------------- ERROR: <somewhere>.math.umn.edu: [could not access /dev/mapper/VolGroup00-LogVol00 (root): Permission denied] Client check: 3 hosts checked in 0.024 seconds, 1 problem found Expected Results: Amanda Backup Client Hosts Check -------------------------------- Client check: 3 hosts checked in 0.024 seconds, 0 problems found Additional info: I don't know if it's udev that sets the permission (lvm might?), but it's been the culprit for other things, so I might as well.
$ udevinfo -q all -n /dev/mapper/Vol1-lvol0 device not found in database lvm devices do not seem to be created by udev.
Indeed, doesn't use udev. Already addressed in 1.00.20 which should be included in U1.
