Interesting. I do use LVM so I could do the same. There's a good article at:

That seems to suggest it may be worth the extra effort of configuring bcache IIUC. I might have a go with my new SSD; it seems like a sensible way to use part of it.
One difference seems to be that you can add an SSD cache to a populated LVM filesystem, whereas bcache needs you to create a new cached filesystem, I think.
The choice of lvmcache was easy - we're using lvm anyway (of course), and it was so easy to add to existing systems. I'm not sure exactly when we did it, it was at least a year ago. The SSD are relatively small - 240Gb I think. Not at all expensive either.
Given what the comments say about losing the entire filesystem if the cache drive dies, and inability to take backups, have you found any solutions? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
