About mhddfs
mhddfs is a FUSE-based tool that merges multiple filesystems into one unified virtual filesystem. It intelligently distributes files across available drives based on free space, ensuring seamless data management without the need for complex RAID setups. Ideal for users with multiple drives who want to avoid manual file organization or reliability issues.
FAQ
mhddfs is a FUSE filesystem module that combines several smaller filesystems into one big virtual filesystem. It allows you to manage files across multiple drives as if they were all in one location, intelligently placing new files on drives with available space.
To set up mhddfs, install the package using your package manager, create a mount point (e.g., /mnt/virtual), and then use the mhddfs command to mount your drives. For example: mhddfs /mnt/hdd1,/mnt/hdd2,/mnt/hdd3 /mnt/virtual -o allow_other.
Yes, you can use mhddfs with non-root permissions by being a member of the fuse group. The -o allow_other option ensures the filesystem is visible to all users.
If a drive runs out of space during a write, mhddfs will transparently transfer the already written data to another drive with available space and continue the write process without failing.
To stop using mhddfs, you can copy all files from the virtual filesystem to a new drive, then unmount the mhddfs mount point and disconnect the old drives. Your data and directory structure will remain intact.
Yes, the mhddfs package is readily available in Debian and likely in many other Linux distributions as well.
