Ssd health check means4/9/2023 ![]() ![]() OnApp SAN Controller services is not responding on the node. Node reachable over the storage API, but is not sending out pings. This can be a bit tricky if there are more than one storage controllers running on the same compute resource, and only one has shutdown. Make sure that there is sufficient redundancy such that restarting controllers on one compute resource will not cause VS downtime.Įither the compute resource hosting the node is not reachable, or it is and is reporting that the storage controller for the node is not running.Įither power-cyclethe compute resource,orbring up the storage controller VS. Possibly storage API is not responding on the storage controller server. The compute resource hosting the node is reachable, and reports over the API that the node is running. Shows the list of disks within active cache. If you want to remove only some items, you can click the Forget button next to the specific item. ![]() To resolve, use a Forget All button in Actions column to forget all items in the list. These can be the disks that have missing partial members, missing inactive members, missing active members, or missing unknown members. The list of vDisks that are degraded but not in any of the other states above. The task may leave some zombie disks left, so check for unremoved disks upon task completion. This task unmounts,performs unkpartx, makes zombie disks offline on each compute resource from the zone, and then removes the disk. To resolve, use a bulk Delete All link in Action column that will create a background task. These may include vDisks created by the command line and vDisks created for benchmarks. The list of vDisks that are not associated with a VS have been found. This task makes zombie snapshots offline on each compute resource from the zone, and then removes the snapshot. To resolve this, use a bulk Delete All link in Action column that will create a background task. The list of vDisk snapshots created during the backup procedure but still left after the backup is deleted. The task may leave some snapshot vDisks left, so check for unremoved vDisks upon task completion. This task unmounts, performs unkpartx, makes zombie snapshots offline on each compute resource from the zone, and then removes the snapshot. Backups cannot be made from a degraded snapshot. The list of vDisk snapshots in degraded states (except ones currently being used for ongoing backups). Status of the vDisk before will show offline but one or more members will show an online front end. Use a Repair link in the Action column that will issue a special Storage API call (online refresh action) to fix this problem. There must be an authoritative member for each stripe. The list of vDisks that have at least one stripe online and at least one stripe offline. ![]() This will allow the content of a vDisk to be rebalanced to another suitable disk drive. Use a Rebalance link in the Actions column that leads to re-balance page for a vDisk. vDisk is healthy but all replicas of a stripe are on the same compute resource. One or more vDisks have not got a replica stripe member on another compute resource. If a vDisk is in this category then the associated VS is likely broken unless the vDisk is a swap drive. There is no redundancy at this point for this stripe and the data is lost. Shows the list of vDisks which have lost all replicas for a stripe. Once the membership is repaired, the vDisk will be in a degraded state until it is re-synced. This will elect a new valid member from the suitable nodes in the data store. Use the repair operation to repair the membership. Each vDisk should have (S)tripe * (R)eplica members. Shows the list of vDisks having an incomplete membership list, due to disk failure, network failure or otherwise. The repair button starts a repair task that will take some time depending on the data store, network and disk drive configuration Use the repair all option to queue the repairs.Repair will resynchronise the content from an elected master to a slave. Degraded vDisks are listed with the OnApp vd_uuid and a repair option. Shows the list of vDisks in a degraded state, which means that one or more (but not all) replicas of a stripe are not fully synchronised. ![]()
