I have a merged partition from 3 different hard drives with mergerfs. I set it up following this tutorial.

To automate the mounting I added instructions in the fstab :

UUID=b3c8301c-5d12-4ab1-ab8c-9249e81978df   /   ext4    rw,relatime,data=ordered 0 1
UUID=f510cf24-8253-4178-99dd-a23a02e912c1   /boot   ext4    rw,relatime,data=ordered 0 2
UUID=9a586ac1-ba39-4004-8ed8-3a6956ae23e7   swap    swap    defaults    0 0
UUID=a3f39fe8-0917-4990-9264-8814a7d0a3b3   /mnt/data_01    ext4    defaults 0 2
UUID=1c78e917-e81c-4719-aecd-211326a579aa   /mnt/data_02    ext4    defaults 0 2
UUID=ac5599bf-0c3b-4785-bc3d-a0cddd32fe28   /mnt/data_03    ext4    defaults 0 2
/mnt/data_* /mnt/data   fuse.mergerfs   defaults,allow_other,use_ino,fsname=data_merger 0 0

When I do mount -a the first time it fail with this message : fuse: device not found, try 'modprobe fuse' first. So I do it and the second mount -a works perfectly. After this, the merged partition behave as expected.

But when I reboot, the partition is not mounted. I assumed that is because modprobe fuse is not run before the fstab process. I don't know how to manage it, I read that rebuild the kernel with fuse could be a solution, but it seems a bit overkill.

Any idea?

  • if it is Ubuntu(It should depend on grub but double check) use insmod fuse in /boot/grub/grub.cfg. Issue is you have to call module before mounting file system.

  • It's Alpine Linux, I will check if it's possible here too.

  • @asktyagi I don't have grub in Alpine

  • Please check append option in syslinux, if that having any option to load kernel. Else you have to take different way to fix.

  • @asktyagi I don't see any append option when I run syslinux --help

I found a simple an elegant solution : register fuse in /etc/modules. Adding this one in this file do the trick since they are loaded before fstab.
