Hi, I have this entry in fstab
/dev/mapper/vg0-opt /opt btrfs rw,discard,relatime,commit=120 0 0 but after a reboot I see /dev/mapper/vg0-opt on /opt type btrfs (rw,relatime,discard,space_cache, *commit=360*,subvolid=5,subvol=/) Am I missing something? is it not sufficient? to give commit=360 in the fstab line ? Can someone help please ... $ uname -r 4.19.0-bcv+ $ lsb_release -a No LSB modules are available.
