I’m going to replace my current HDD by a faster SSD (2TB), create a boot partition (1GB) and an LVM partition (home: 30GB, music: 1TB, videos: 10GB, timeshift: 60GB).
I believe I should keep some space reserved for Over-Provisioning. How am I supposed to do that ? Can I use the tune2fs option to set reserved blocks for the superuser for the boot partition and each LV (-m) ? How much space is that ?
Use gparted from a usb stick to partition the ssd.
There will already be a certain amount of vendor configured overprovisioning.
If you want room for further user configured overprovisioning, just leave some of the space free. My understanding is that the system will use free space if it needs it, I dont think you have to do anything special, other than leave some space. I dont think it matters where the free space is, but I would put it at the beginning of the disk.
