How can I add storage bucket in JuiceFS?
问题
I am trying to learn how JuiceFS works.
So if I had two computers on the LAN with 192.168.1.11 and 192.168.1.12 IP addresses, and a third with 192.168.1.100 (for metadata), and a fourth computer on the same LAN where I did this:
juicefs format
--storage sftp
--bucket 192.168.1.11:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/1 myjfs #metadata db
juicefs format
--storage sftp
--bucket 192.168.1.12:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/1 myjfs #metadata db
Can I mount the JuiceFS like this:
juicefs mount redis://192.168.1.100:6379/1 ~/jfs
Will it appear as a filesystem with storage capacity of the two computer (192.168.1.11 and 192.168.1.12)?

不，一个 JuiceFS 文件系统由一个数据库和一个存储组成。所以，只需执行以下命令之一即可：
juicefs format \
--storage sftp \
--bucket 192.168.1.11:myjfs/ \ #远程 sftp/ssh 地址和路径
--access-key tom \ #用户
--secret-key 123456 \ #密码
redis://192.168.1.100:6379/1 myjfs #元数据数据库
或者只需执行以下命令之一即可：
juicefs format \
--storage sftp \
--bucket 192.168.1.12:myjfs/ \ #远程 sftp/ssh 地址和路径
--access-key tom \ #用户
--secret-key 123456 \ #密码
redis://192.168.1.100:6379/1 myjfs #元数据数据库
第一个命令成功执行后，第二个命令将报告错误。
所以，当您通过以下命令挂载文件系统时：
juicefs mount redis://192.168.1.100:6379/1 ~/jfs
您将使用位于 192.168.1.11:myjfs/ 上的存储，而不是 192.168.1.12:myjfs/。
当然，如果您希望充分利用两台计算机上的存储空间，那么您可以为每个文件系统格式化两个文件系统，注意每个文件系统应使用不同的数据库。例如：
juicefs format \
--storage sftp \
--bucket 192.168.1.11:myjfs/ \ #远程 sftp/ssh 地址和路径
--access-key tom \ #用户
--secret-key 123456 \ #密码
redis://192.168.1.100:6379/1 myjfs1 #元数据数据库
juicefs format \
--storage sftp \
--bucket 192.168.1.12:myjfs/ \ #远程 sftp/ssh 地址和路径
--access-key tom \ #用户
--secret-key 123456 \ #密码
redis://192.168.1.100:6379/2 myjfs2 #元数据数据库
请注意文件系统名称和redis数据库编号，然后您可以通过以下命令挂载它们：
juicefs mount redis://192.168.1.100:6379/1 ~/jfs1
juicefs mount redis://192.168.1.100:6379/2 ~/jfs2
英文:
Nope, a juicefs filesystem composed of one database and one storage. So, only:
juicefs format \
--storage sftp \
--bucket 192.168.1.11:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/1 myjfs #metadata db
or only
juicefs format \
--storage sftp \
--bucket 192.168.1.12:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/1 myjfs #metadata db
is enough.
After the first command to create the file system is executed successfully, the second command will report an error.
So, when you mount the filesystem via:
juicefs mount redis://192.168.1.100:6379/1 ~/jfs
You will be using the storage on 192.168.1.11:myjfs/, not 192.168.1.12:myjfs/.
Of course, if you wish to make full use of the storage space on both PCs, then you can format two file systems for use, noting that each file system should use a separate db. For example:
juicefs format \
--storage sftp \
--bucket 192.168.1.11:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/1 myjfs1 #metadata db
juicefs format \
--storage sftp \
--bucket 192.168.1.12:myjfs/ \ #remote sftp/ssh addresss and path
--access-key tom \ #user
--secret-key 123456 \ #pass
redis://192.168.1.100:6379/2 myjfs2 #metadata db
Please note that the filesystem name and the number of redis db, and then you can mount them via:
juicefs mount redis://192.168.1.100:6379/1 ~/jfs1
juicefs mount redis://192.168.1.100:6379/2 ~/jfs2
