iso installer fails to save btrfs fstab options or subvol changes


I’m installing OpenSUSE 42.1 Leap & have a few btrfs volumes on an SSD & when I click the ‘finish’ button to save changes I made to fstab options (noatime & ,discard) it reverts & won’t save the changes. It also fails to save after I remove subvolumes from the drives & I end up with duplicates in tmpfs.

Please help!


Hi and welcome to the forum :slight_smile:
Most of the optimizations for btrfs and SSD’s are already taken care of during install, it’s easier to tweak later if you really want too.

/ type btrfs (rw,relatime,ssd,space_cache....

Trim is also taken care of via a weekly crobjob;


For the scheduler this is handled via a udev rule (esp if also have rotating disks as well) and is recommended at deadline these days, more info here;;
