Free space - Repetitio mater studiorum est :D

[sanjac]

I know that we had this topic but I stee having trouble calculating/finding free space on my Primera sistem. Can please someone help.. The numbers I'm seeing on Primera UI doesn't make sense...

LDfree in showspace -cpg is as correct as it will get.

Remember this number excludes any possible saving with compression/dedupe.

Also Infosight now shows capacity utilization in both RAW and usable, as of a recent update.

You're not...

Out of the 35750 GiB, 7150 GiB are reserved as spare (equal of minimum 2 drives which was known as "default" in 3PAR days).
Then you're left with 28600 GiB.

Raid 6 (8+2) should give you 20% RAID overhead, so of the 28600 RAW 5720 will be lost to parity.

That leaves you with 22880 GiB or just over 22TiB of net capacity (pre datareduction).

Your SSD_r6 CPG is today 14+TB (with ~almost 4TB free that could be relased with compactcpg) and it can grow by 7+TB more.

The numbers look correct to me.

Thank you! It makes a sense now
