Subject: Adding caching to existing volumes?
Date: Sat, 19 Jan 2013 19:08:25 +0100 (CET) [thread overview]
Message-ID: <17989056.10.1358618905144.JavaMail.root@zimbra> (raw)
Hi all
As far as I can understand from the bcache docs, a volume cached with bcache, must be formatted and setup for bcache in the first place. I come from a ZFS environment, where adding SLOG or L2ARC is done dynamically, so I have a few questions:
- Would it be somewhat possible to add caching to an existing volume and its data?
- What would happen if the cache device dies - does the whole filesystem become inaccessible?

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
