Storage checks

Checks on every storage, on each node that can use it. How to read the codes: Overview.

Availability

Section titled “Availability”
Code SubContext Gravity Description
CS0001 Status Critical Storage is not accessible on a node (shared storages are checked on every node)
WS0008 Status Warning Storage is disabled but an enabled backup job or a guest still uses it

Capacity

Section titled “Capacity”
Code SubContext Gravity Description
WS0009/CS0009 Usage WarningCritical Storage usage above configured threshold
WS0004 ThinOvercommit Warning Disk space allocated to guests exceeds the capacity of a thin storage (LVM-thin and ZFS per node, Ceph RBD and CephFS for the cluster; container mount points mp* excluded)
WN0044/CN0044 Zfs WarningCritical ZFS pool disk usage above configured threshold

Backups and orphaned data

Section titled “Backups and orphaned data”
Code SubContext Gravity Description
WS0003 Backup Warning Backup files whose VMID no longer exists (one finding per VMID and storage)
WS0006 Backup Warning No storage has ‘backup’ content type — backups cannot be stored
WS0007 Backup Warning Enabled backup job storage not enabled on a node it runs on — VMs there not backed up (a storage enabled but not reachable is CS0001)
WS0002 Image Warning Disk image or container volume not attached to any VM/CT on that node

Any of these can be hidden with an ignore rule on its code.
