| Summary | 0000107: lvcreate/lvremove not honoring lvm.conf | ||||
| Description | Per RHEL's bugzilla, the issue of lvcreate/lvremove was fixed years ago to automatically ignore previous signatures when wipe_signatures_when_zeroing_new_lvs=1 is set in /etc/lvm/lvm.conf. # lvcreate -L 10G -n test vg_h6 WARNING: ext4 signature detected on /dev/vg_h6/test at offset 1080. Wipe it? [y/n]: n Aborted wiping of ext4. 1 existing signature left on the device. Failed to wipe signatures on logical volume vg_h6/test. Aborting. Failed to wipe start of new LV. While the -y flag exists and does work, it's not supposed to be required. # lvcreate -y -L 10G -n test vg_h6 Wiping ext4 signature on /dev/vg_h6/test. Logical volume "test" created. I have tested this on Fedora 33, RHEL8, CentOS 6/7/8 and Amazon Linux and they honor the lvm.conf Below are some previously reported issues about this. https://bugzilla.redhat.com/show_bug.cgi?id=997223 https://bugzilla.redhat.com/show_bug.cgi?id=1946199 | ||||

I ran into this when doing a fresh install over an existing CentOS installation. After installation I was unable to boot from the HD with an error indicating dracut scan for cl/root and cl/swap failed. I could only boot by using the installation thumb drive, which I could then remove. Practical solution for this instance was to rename the volume group name to cl. I can now boot normally from the HD. I used the one line script from here to accomplish the renaming: https://forums.centos.org/viewtopic.php?t=62406 |
