=== Extend a volume === | |||
This is very easy because btrfs incorporates a volume manager. You only have to look for a free device. You may use a partition like ''/dev/sdz4'' or you may use a raw device like ''/dev/sdz''. Then add this device to your existing volume with '''btrfs device add'''. You may need to do a '''balance''' afterwards to redistribute some chunks. | |||
{{BoxWarning|Dont´t format the partition!|To add a device it should have NO filesystem on it. The btrfs volume manager will include the free storage of the device '''into the existing filesystem'''.}} | |||
