Warning A TmpDisk will not survive a restart or ejecting. No need to worry about deleting, trash or cleaning up temporary files anymore. Any files stored on a RamDisk will be permanently deleted when the disk is ejected. RamDisks can be any size, limited only by your total memory and lightning fast.

But that’s fine for temporary directories and (for my purposes) package builds. It’s important to note that these are scratch disks so when the client unmounts the filesystem it is completely deleted from the server. ![]() But it’s also scriptable, so you can substitute any command you like instead of mkfs to create your own custom disks (I recommend looking at mke2fs -d in case you need to have pre-populated scratch disks). By default it creates a new disk for each connection, formats it with mkfs and serves it to the client. To get a new “remote tmpfs”, a fresh filesystem each time, the client does:īacking this is a flexible new plugin called tmpdisk. However nbdkit didn’t quite do what I wanted, so I had to write a new plugin. I’m using nbdkit, the high performance flexible NBD server. But for the clients that are build servers I selected NBD as a high-performance block-based storage. And indeed I selected that for /home where performance is not a problem. As I didn’t want to set up multiple server nodes or need the redundancy, cluster filesystems are immediately discounted. Any filesystems that might be heavily used must be network filesystems.Īs these are Linux clients we essentially have three possible choices for network filesystems: NFS, NBD or a cluster FS. These are based on the HiFive Unleashed U540 board and so they have no local SATA, only slow, unreliable SD cards. ![]() I was making some thin clients for the Fedora RISC-V project a few weeks ago. ![]()
