Hi experts,
I've been trying to determine some space allocations on a HyperFlex cluster via an ssh session to a Storage Controller VM.
I've discovered that I can turn off the HyperFlex cleaner with the command
stcli cleaner stop
And I can start it again with
stcli cleaner start
But at any given time, I don't seem to have a way of determining if either of these commands has been run.
The only other stcli cleaner commands that are available are: (from the CLI Guide with my annotations)
| Option |
MY NOTES |
Description |
| get-schedule |
ALWAYS reports policyActive as False
(perhaps reports True if command run
while cleaner is running)
|
Reports storage cluster cleaner high priority schedule.
|
| info |
Only gives IP/ID and Online status
|
Provides information about the specified storage cluster cleaner.
|
| report |
Gives space info per node,
but nothing about times
|
Reports storage cluster space reclaimed from cleaner.
|
| set-schedule |
|
Sets storage cluster cleaner high priority schedule.
|
| start |
|
Starts storage cluster cleaner.
|
| stats |
Gives space info per disk,
but nothing about times
Has an optional --start option
|
Collects storage cluster cleaner stats.
|
| stop |
|
Stops storage cluster cleaner.
|
I've added some samples below.
I'd be grateful if anyone can tell how to determine if the HX Cluster has had had the stcli cleaner stop command run, either from the command line or using the HyperFlex API.
