Description of problem: Certain RAID meta-devices that are part of LVM sets, rather than being used directly as filesystems, fail to start up during the boot sequence with the annotation "(skipped)". This causes big problems with LVM volume group startup. Version-Release number of selected component (if applicable): initscripts-7.55.1-1 How reproducible: Every time Steps to Reproduce: 1. Create RAID 5 array 2. pvcreate as an LVM physical volume 3. vgextend it into a volume group 3. Use some of this new space for a LV 4. reboot Actual results: The init sequence instead of listing md8 as one of the meta devices enabled, lists it as md8(skipped). Then the LVM reports that it cannot enable the VG that contains this MD. Then the boot sequence collapses as the LVs that are now not present fail to fsck. Expected results: It should either not care why this MD is around, or it should check for the presence of the MD in a pvscan listing .. or some such. Additional info: I haven't got to the bottom of this yet, but it only seems to do this for RAID 5 arrays. I have been doing this MD under LVM structure for a while now and it hasn't caused a problem before. I just now got enough disks to out a 3rd in this machine and raid5 it, now it fails.
I am seeing the same issue. The problem resides in /etc/rc.sysinit. On line 492 the following code checks to see if the raid device belongs to a filesystem: INFSTAB=`LC_ALL=C grep -c "^$i" /etc/fstab` if [ $INFSTAB -eq 0 ] ; then RESULT=0 RAIDDEV="$RAIDDEV(skipped)" fi In both cases (mine and the original but reporters) the software raid becomes part of a LVM volume (I'm using RAID 1+0).
sorry I should have added this before. Doing a pvscan will not help as the raid array is not active so no uuid's belonging to a volume group will be found.
Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match.
This is solved with the use of mdadm in FC3 and later.
