Hey, I’m starting to use LVM (+LUKS) on a computer of mine, but ran into trouble getting it to work. The issue I’m running into is that systemd boot hangs until the default unit timeout elapses. This is because the cryptroot device is not found, which in turn is because udev doesn’t create the symlinks (e.g. in /dev/disk/by-uuid). udevadm info shows: # udevadm info -p /sys/block/dm-0 P: /devices/virtual/block/dm-0 N: dm-0 L: 0 E: DEVPATH=/devices/virtual/block/dm-0 E: DEVNAME=/dev/dm-0 E: DEVTYPE=disk E: MAJOR=254 E: MINOR=0 E: SUBSYSTEM=block E: USEC_INITIALIZED=6522555 E: DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG=1 E: DM_UDEV_DISABLE_DISK_RULES_FLAG=1 E: DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 E: SYSTEMD_READY=0 E: TAGS=:systemd: I pinpointed this result to udev rule https://sourceware.org/git/?p=lvm2.git;a=blob;f=udev/10-dm.rules.in;hb=ecae76c713bd4fa6c9d8f2a2c990625e4f38b504#l87, i.e.: ENV{DM_UDEV_RULES_VSN}!="1", ENV{DM_UDEV_PRIMARY_SOURCE_FLAG}!="1", GOTO="dm_disable" I assume I’m running into this rule because I’m using a custom initrd which does not run systemd nor udev. Instead, my initrd is directly calling vgchange -ay and vgmknodes. I understand that this is not a common setup, but booting without systemd/udev in the initrd should be supported, no? I’m not sure where DM_UDEV_PRIMARY_SOURCE_FLAG is supposed to be set, or why it isn’t set in my scenario. Do you have any ideas regarding what I could check? Thanks in advance, Best regards, Michael PS: As a workaround, I’m just commenting out that rule. Does that have any negative consequences? _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
