Getting the date and time when a partition was last mounted is very easy. This is done with the tune2fs utility.
[root@localhost john]# tune2fs -l /dev/sdb1 | grep 'Last' Last mounted on: /mnt/ubuntu Last mount time: Fri Apr 28 06:42:01 2023 Last write time: Fri Apr 28 06:42:01 2023 Last checked: Sun Dec 19 17:29:12 2021 |
This is very simple.
Create a dump of information about your LVM partition configuration using this easy command. This generates a report tarball in your /root directory.
[root@localhost john]# lvmdump Creating dump directory: /root/lvmdump-localhost-20230427215722 Gathering LVM & device-mapper version info... Gathering dmsetup info... Gathering process info... Gathering console messages... Gathering /etc/lvm info... Gathering /dev listing... Gathering /sys/block listing... Creating report tarball in /root/lvmdump-localhost-20230427215722.tgz... |
Just unpack the tarball.
[root@localhost ~]# tar -xvf lvmdump-localhost-20230427215722.tgz |
Then all of the files are available to peruse.
Like this one.
[root@localhost lvmdump-localhost-20230427215722]# cat dmsetup_info Name Maj Min Stat Open Targ Event UUID rl-home 253 2 L--w 1 1 0 LVM-jP0sHNAmgN6HwNJD2ETs3HBxDgofqXd0WM62tPDchAzGO7B7LvYyVkCsn3brBDKD rl-root 253 0 L--w 1 1 0 LVM-jP0sHNAmgN6HwNJD2ETs3HBxDgofqXd0PcMJxndMYq1Yt6Jf8qVPH2f4LsRCdtjK rl-swap 253 1 L--w 2 1 0 LVM-jP0sHNAmgN6HwNJD2ETs3HBxDgofqXd01dua01BUemhmlf54y26kWG5kQ0LiuJp6 |
And this one.

This will provide a lot of very useful information about your LVM configuration on Linux.
