Unable to mount lvm os disk snapshot on other vm for troubleshooting issue.
Yesteday , our one of the vm was not booting and going to emergency mode due to issue of invalid entry in fstab and unfortunalty we don't have root password . so thought to take sanpshot of root disk and create new disk with sanpshot and mount to other vm and change entry in fstab . but as os disk root partition was part of lvm so I was unable to mount it on other vm ...it was displaying error message "mount: unknown filesystem type 'LVM2_member'" lvm something .
[root@azre3lpdukd01 ~]# mount /dev/sdj4 /mnt/troubleshootingdisk
mount: unknown filesystem type 'LVM2_member'
I have referred document
Kindly let us know if any solution for this.
