Hi list. I ran into the strange problem. After creating encrypted swap (with crypttab) boot hangs. That happens because systemd waits for dev-mapper-swap.device.
Udev doesn't report that this device active, because SYSTEMD_READY environment set to "0". That happens because "change" event was not generated. "Change" event was not generated, because udev doesn't receive inotify event after mkswap closes device. I come to this after verifying manually these steps: 1. Set udev log_level to debug 2. Attach device with systemd-cryptsetup 3. Verify that inotify for device was added (no errors in debug log, device in /run/udev/watch). Also I attach strace to systemd-udev. 4. Run mkswap /dev/mapper/swap 5. Check, that there was no any activity by systemd-udev (according to strace - no event, according to the logs - no processing) After figuring out this, I double check systemd requirements with /README.txt I'm running linux-4.1.3, systemd (c11ae0bacee4ab835526a7408f619a754b3b848e) Also I have this in config CONFIG_FHANDLE=y CONFIG_CGROUPS=y CONFIG_CGROUP_SCHED=y CONFIG_FAIR_GROUP_SCHED=y CONFIG_CHECKPOINT_RESTORE=y CONFIG_NET_NS=y CONFIG_EPOLL=y CONFIG_SIGNALFD=y CONFIG_TIMERFD=y CONFIG_SECCOMP_FILTER=y CONFIG_BLK_DEV_BSG=y CONFIG_EFI_PARTITION=y CONFIG_SECCOMP=y CONFIG_DEVTMPFS=y CONFIG_DEVTMPFS_MOUNT=y CONFIG_DEVPTS_MULTIPLE_INSTANCES=y CONFIG_DMIID=y CONFIG_EXT3_FS_POSIX_ACL=y CONFIG_EXT4_FS_POSIX_ACL=y CONFIG_REISERFS_FS_POSIX_ACL=y CONFIG_XFS_POSIX_ACL=y CONFIG_BTRFS_FS_POSIX_ACL=y CONFIG_F2FS_FS_POSIX_ACL=y CONFIG_FS_POSIX_ACL=y CONFIG_INOTIFY_USER=y CONFIG_AUTOFS4_FS=m CONFIG_PROC_FS=y CONFIG_SYSFS=y CONFIG_TMPFS_POSIX_ACL=y CONFIG_TMPFS_XATTR=y CONFIG_EFIVAR_FS=m CONFIG_SCHED_DEBUG=y CONFIG_SCHEDSTATS=y I use next workaround: cat /etc/systemd/system/systemd-cryptsetup@swap.service.d/override.conf [Service] ExecStartPost=/usr/bin/udevadm trigger -t devices -p SYSTEMD_READY=0 So.. What I should check to make all that run properly? // wbr // Oleksii Shevchuk _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
