If you use a clustered filesystem then you can safely mount it on multiple machines. If you use a non-clustered filesystem it can still mount and even appear to work for a while. It's surprising how many writes you can make to a dual- mounted filesystem that's not designed for such things before you get a totally broken filesystem.

I've tried this with dual-attached FC and had no problems mounting. In what way is directly connected SCSI different from FC? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
