These partitions across devices form a 2-leg RAID1 array via md/mdadm. That RAID1 array itself is in use as a Physival Volume for LVM2, and it hosts a Volume Group with a Logical Volume at /dev/mapper/vg_raid1-root that you want to resize. > [...] With these assumptions verified, the operation you are about to execute seems perfectly safe to me. You can even make `lvresize` perform the fs resizing for you, and shorten the whole ordeal to just # lvresize --size +50GB --resizefs /dev/mapper/vg_raid1-root Godspeed, and remember to always keep working backups handy regardless! ;) -- with best regards: - Johannes Truschnigg ( johannes@xxxxxxxxxxxxxxx ) www: https://johannes.truschnigg.info/
