Can You Mount multiple files in one directory?

Can You Mount multiple files in one directory?

Think a union of sets. The file/s or directory/s acted on or presented through mergerfs are based on the policy chosen for that particular action. mergerfs does not support the copy-on-write (CoW) behavior found in aufs and overlayfs. You can not mount a read-only filesystem and write to it.

Is there a way to combine multiple partitions into one?

Another solution is to set up RAID so that files can be spread evenly across the various disks, but the lack of redundancy could be a cause for concern. mhddfs is a FUSE filesystem module that allows you to combine several partitions (or hard disks) into one virtual drive.

Can a FUSE filesystem merge multiple directories together?

It is a FUSE filesystem which merges multiple directories: https://github.com/trapexit/mergerfs mergerfs logically merges multiple paths together. Think a union of sets. The file/s or directory/s acted on or presented through mergerfs are based on the policy chosen for that particular action.

What are the advantages and disadvantages of multiple partitions?

Generic advantages of having multiple partitions: You can use different disks/LUNs and have better performance. This can increase the performance of the databases as you can have the transaction log on a storage and the data files on another.

Is it possible to Mount Read Only files?

You can not mount a read-only filesystem and write to it. However, mergerfs will ignore read-only drives when creating new files so you can mix read-write and read-only drives. It also does not split data across drives. It is not RAID0 / striping.

What happens if I unmount one disk on my computer?

You can unmount like this: If one disk fails you only lose the files that was stored on that particular disk. If your data is important for you and you would like your data to survive a disk failure you should consider a RAID setup instead (search for mdadm).
