Is it safe and 'recommended' to reclaim/shrink oracle/sysadmin volumes in DOT 7 mode

curious_V — Wed, 04 Jun 2025 21:08:22 GMT

We have created several flexvolumes such as 1 flex volume contains 1 qtree.

these volumes are created in the similiar way for oracle and Sys Admin's

e.g

oracle volume - /vol/oratla_data/oratla_data

Sys Admin Volume - /vol/traces/traces

These volumes are fully allocated volumes (not thin-provisioned)

Now, in few volumes we can see very less utilised capacity and hence want to shrink/reclaim it .

Want to know is it safe to reclaim spaces from Oracle / Sys Admin volumes or is there a slightest of chance for data loss.

I understand this is driven by WAFL and hence intelligent enough to reclaim only the empty/zero blocks from volumes - but still want to know if it is 100% safe.

Please comment and help me with any best practice doc related .

if you see the free space, you can resize the volume. it's safe. if you're not so sure, ask ur ps guy to help?
