Quick Ops Cheat Sheet

Action	Where To Go	Why	Outcome
Create a storage pool	Storage > Pools > + Create Pool	Establishes a storage domain for file, block, or object workloads.	Pool is listed and converges to active+clean.
Verify file system readiness	Storage > File System > Expand row > Details, MDS Ranks	Confirms metadata service health before client onboarding.	Active and standby MDS visibility is confirmed.
Create an NFS export	Storage > NFS Shares > + Create Export	Exposes DFS data to standard NFS clients.	Export is listed and mount-ready.
Create an RBD image	Block Storage > Block Images > Images > + Create Image	Provides block disk capacity for VM or volume workloads.	New image appears with provisioned usage tracking.
Create and protect snapshot for clone workflow	Block Storage > Images > Expand row > Snapshots	Creates rollback/checkpoint and enables clone creation.	Snapshot is available and can be cloned when protected.
Flatten a clone	Block Storage > Images > ⋮ > Flatten	Removes parent dependency before parent cleanup or migration.	Clone becomes standalone.
Restore image from trash	Block Storage > Trash > Restore	Recovers a soft-deleted image within retention window.	Image returns to active Images list.
Create object user and retrieve keys	Object Storage > Users > + Create User > Keys tab	Generates credentials for S3/Swift clients.	Access key and secret key are available for client setup.
Create a bucket	Object Storage > Buckets > + Create Bucket	Provides object container for uploads.	Bucket appears with owner and empty object count.
Put host in maintenance mode	Infrastructure > Hosts > ⋮ > Maintenance Mode	Safely prepares host for hardware work.	OSD drain/rebalance starts and host enters maintenance state.
Reweight an OSD	Infrastructure > OSDs > ⋮ > Reweight	Shifts data distribution when one OSD is overloaded.	PG/data distribution adjusts over time.
Create service	Infrastructure > Services > + Create Service	Deploys required cluster daemons to eligible hosts.	Service appears and running count rises to target.
Silence an alert	Monitoring > Alerts > Silences > + Create Silence	Suppresses expected maintenance noise without disabling alert evaluation.	Matching alert notifications are suppressed for configured window.
Expire a silence	Monitoring > Alerts > Silences > Expire	Restores normal alert notification behavior after maintenance.	Silence status becomes Expired and notifications resume.
Download logs for analysis	Monitoring > Logs > Cluster Logs or Audit Logs > Download	Captures filtered evidence for troubleshooting and escalation.	Exported log file is available for sharing.
Run benchmark	Monitoring > Benchmark > select tab > Select target node > Run	Validates performance after infrastructure change.	Benchmark history includes IOPS, throughput, and latency results.

Safe Operations Checklist

Before Action	Validate	Why It Matters
Any storage create/edit/delete	Dashboard health and capacity	Prevents changes during degraded cluster state.
OSD maintenance and mark-out operations	Replication health and available headroom	Reduces data-risk during rebalance.
Snapshot rollback or destructive delete	Backup/restore plan and workload dependency check	Prevents irreversible data loss.
Alert silencing	Clear maintenance window and comment	Preserves auditability and avoids hidden long-running faults.
Benchmark execution	Low-traffic window and non-production target	Avoids noisy-neighbor impact on active workloads.

Warning

Destructive actions such as delete, purge, rollback, and rule/profile removal are irreversible in normal workflows. Confirm dependency and data-impact checks before execution.
