Hi, As the "lvs -a" shows as followed, the "data" volume on "VG" is a mirrored logical volume. The underlying volumes are data_rimage_0, data_rimage_1, data_rmeta_0 and data_rmeta_1. When the systemd boot up, the LVM should activate the "data" volume. But now, it only activate the four underlying volumes. It causes systemd unable to mount some mountpoint. I can manually deactivate these volumes using "lvchange -an", and activate the "data" volume. After that, the "data" volume works normally. Please help me to resolve this issue. I can provide more information if needed. I am running an archlinux, using the newest lvm package (version: 2.02.187(2)). kXuan-nas% sudo lvs -a   LV                      VG Attr       LSize   Pool Origin Data% Meta%  Move Log Cpy%Sync Convert   data                    VG rwi---r--- 2.00t   data-ext4-journal       VG -wi-a----- 1.00g   [data_rimage_0]         VG Iwi-a-r-r- 2.00t   [data_rimage_1]         VG Iwi-a-r-r- 2.00t   [data_rmeta_0]          VG ewi-a-r-r- 4.00m   [data_rmeta_1]          VG ewi-a-r-r- 4.00m   home                    VG rwi---r--- 50.00g   home-ext4-journal       VG -wi-a----- 1.00g   [home_rimage_0]         VG Iwi-a-r-r- 50.00g   [home_rimage_1]         VG Iwi-a-r-r- 50.00g   [home_rmeta_0]          VG ewi-a-r-r- 4.00m   [home_rmeta_1]          VG ewi-a-r-r- 4.00m   laptop_iscsi            VG rwi---r--- 500.00g   [laptop_iscsi_rimage_0] VG Iwi-a-r-r- 500.00g   [laptop_iscsi_rimage_1] VG Iwi-a-r-r- 500.00g   [laptop_iscsi_rmeta_0]  VG ewi-a-r-r- 4.00m   [laptop_iscsi_rmeta_1]  VG ewi-a-r-r- 4.00m   old_home                VG -wi-a----- 50.00g   root                    VG -wi-ao---- 60.00g   LVM version:     2.02.187(2) (2020-03-24)   Library version: 1.02.170 (2020-03-24)   Driver version:  4.41.0   Configuration:   ./configure CONFIG_SHELL=/bin/bash --prefix=/usr --sbindir=/usr/bin --sysconfdir=/etc --localstatedir=/var --enable-applib --enable-cmdlib --enable-dmeventd --enable-lvmetad --enable-lvmpolld --enable-pkgconfig --enable-readline --enable-udev_rules --enable-udev_sync --enable-use-lvmetad --with-cache=internal --with-default-dm-run-dir=/run --with-default-locking-dir=/run/lock/lvm --with-default-pid-dir=/run --with-default-run-dir=/run/lvm --with-systemdsystemunitdir=/usr/lib/systemd/system --with-thin=internal --with-udev-prefix=/usr --enable-udev-systemd-background-jobs The attachment tarball generated by "lvmdump".
