how can i get minio erasure code set size with mcli and how can i get total available size in minio？

mc admin info --json myminio. Look for info/backend/standardSCParity.

thanks for reply，however i can't find per erasure set size

[klauspost]

Oh, yeah, sorry. Find max "disk_index": X, set size is X+1.

thanks，i use follow command to get max disk_index：

mc admin info --json myminio | jq '[.info.servers|.[]|.drives|.[]|.disk_index]|max'

I know it's an older question but never was closed, and google already put this on the first result I want to continue this discussion, and not opening a new one, for it's stay on the top in the search. It has valuably answer.

I'm not exatly understanding the output of mc admin info --json myminio What does the parameters means?

• standardSCParity
• rrSCParity
• set_index
• disk_index

Is this setup good? before I lost all my data because I wrongly configured my minio deployment.

My setup is 4node 8drive/node. 1.2TB/drive

I got this output

	"backendType": "Erasure",
		"onlineDisks": 32,
		"offlineDisks": 0,
		"standardSCParity": 4,
		"rrSCParity": 1,
		"totalSets": [2],
		"totalDrivesPerSet": [16]

set_index: half of the drive is 0 other half is 1
