Hi, I created multiple volumes with the intention to keep all /var stuff in one volume /boot separate, etc. I did this on Opensuse 13.2 in the same way I did on 12.3 only using btrf. What I did not do is setting up subvolumes, but somehow OpenSuse did making my efforts to separate volumes unsuccessful. Can someone tell me which process creates the /boot/grub2/x86_64-efi, /boot/grub2/i386-pc, /var/log, ... subvolumes on the root filesystem ?? opensuse13:~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% / devtmpfs 235M 8.0K 235M 1% /dev tmpfs 242M 88K 242M 1% /dev/shm tmpfs 242M 2.4M 240M 1% /run tmpfs 242M 0 242M 0% /sys/fs/cgroup /dev/mapper/system_13.2-usr_lv 18G 6.9G 10G 41% /usr /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /.snapshots /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /tmp /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /srv /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /usr/local /dev/sda2 486M 59M 398M 13% /boot /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /boot/grub2/x86_64-efi /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /boot/grub2/i386-pc /dev/mapper/export_vg-export_lv 20G 18G 2.9G 86% /export /dev/mapper/export_vg-src_lv 5.0G 2.6G 2.5G 51% /src /dev/mapper/system_13.2-opt_lv 6.0G 152M 5.3G 3% /opt /dev/mapper/system_13.2-var_lv 4.0G 254M 3.4G 7% /var /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/tmp /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/spool /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/opt /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/log /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/lib/pgsql /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/lib/mailman /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/lib/named /dev/mapper/system_13.2-root_lv 5.0G 1.5G 3.2G 32% /var/crash My fstab looks like: opensuse13:~ # cat /etc/fstab UUID=d300b5ad-372b-4f86-b952-4aa4fc62a84e swap swap defaults 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f / btrfs defaults 0 0 UUID=fd14684f-1950-4f33-95b5-b54f069b4fe0 /boot ext4 acl,user_xattr 1 2 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /boot/grub2/i386-pc btrfs subvol=boot/grub2/i386-pc 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /boot/grub2/x86_64-efi btrfs subvol=boot/grub2/x86_64-efi 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /home btrfs subvol=home 0 0 UUID=f535177b-18a5-443c-8236-96105d58a621 /opt btrfs defaults 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /srv btrfs subvol=srv 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /tmp btrfs subvol=tmp 0 0 UUID=62ffc2f3-7e3a-433e-8a4e-5a89a352f8cf /usr btrfs defaults 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /usr/local btrfs subvol=usr/local 0 0 UUID=323ba68a-e7ed-4f0f-9716-dcad92bb9808 /var btrfs defaults 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/crash btrfs subvol=var/crash 0 0 #UUID=323ba68a-e7ed-4f0f-9716-dcad92bb9808 /var/crash btrfs subvol=var/crash 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/lib/mailman btrfs subvol=var/lib/mailman 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/lib/named btrfs subvol=var/lib/named 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/lib/pgsql btrfs subvol=var/lib/pgsql 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/log btrfs subvol=var/log 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/opt btrfs subvol=var/opt 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/spool btrfs subvol=var/spool 0 0 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /var/tmp btrfs subvol=var/tmp 0 0 /dev/export_vg/export_lv /export xfs defaults 1 2 /dev/export_vg/src_lv /src xfs defaults 1 2 UUID=7a681ad4-5b82-4e78-9b20-1d719c89fe6f /.snapshots btrfs subvol=.snapshots 0 0 Thank you Markus
