To monitor the ZFS disk space storage pool file system, you can use the zpool
and zfs
commands. Here are some examples:
- To display information about all ZFS storage pools:
zpool list
- To display the usage statistics for a particular ZFS storage pool:
zpool list -v <pool name>
- To display detailed information about a particular ZFS file system:
zfs list -o name,used,available,referenced,mountpoint <filesystem name>
- To display a summary of ZFS file system usage for all file systems:
zfs list -o name,used,available,referenced,mountpoint
- To display a real-time summary of the storage usage and performance statistics for all ZFS storage pools and file systems:
zpool iostat -v
- To receive notifications when the storage usage of a ZFS file system reaches a specified threshold, use the
zfs set
command:
zfs set quota=<threshold> <filesystem name>
When the usage of the file system exceeds the threshold, an error message will be displayed.
- You can also set a reservation for a ZFS file system to ensure that a certain amount of disk space is always available for that file system:
zfs set reservation=<amount> <filesystem name>
This will reserve the specified amount of disk space for the file system. If the disk space usage of the file system exceeds the reservation, an error message will be displayed.
These commands can help you monitor the disk space usage of ZFS storage pools and file systems, and ensure that you have sufficient disk space available for your needs.
