In the following example, pci 1f,0 is a nexus device. That seems to be a problem, to have to unmount the volume in order to remove the degraded flag, which is needed to begin the rebalance.
Log in to post comments Btrfs: Here we are seeing the added cost of duplicated metadata, among other things; as we will see below, the discrepancy between the available space shown by df and reality is even greater for some of the other storage modes.
Btrfs: Working with multiple devices
When there's more than one drive the metadata defaults to "raid1", but I think they're pretty much the same thing. Do you have a proxy for the remote component? A balance operation involves moving a lot of data between drives, so it can take some time to complete; it will also slow access to the filesystem. This is fully working. But the same task can be accomplished without downtime by converting the array on the fly: That's a poor solution.
Choosing a timeout that is appropriate for a system with 2 drives, and also appropriate for a system with drives is not straight forward Otherwise, one file per disk is better. File systems supporting those classes of problem will become more and more important as long as practical capacity grows faster than practical bandwidth as is the case at the moment.

Posted Jan 2, 2: The kernel uses this association to decide which driver to execute when the user reads or writes the device file. I mean how does the kernel driver talk to the filesystem driver?
Just what the chef recommended. Posted Jan 5, No, there is no Firwall. The minor number must map each driver to a specific device instance.

That is simply one of the universal truths of system administration. Built-in support for RAID arrays is one of the key Btrfs features, but the list of advanced capabilities does not stop there. What is conservative?
Character devices also called character special files behave like pipes, serial ports, etc.
