/zfsauton/data and /zfsauton/project

Dear Autonians,

I poked around the system a bit today while creating a new user account.

It appears that ZFS datasets /zfsauton/data and /zfsauton/project are 100%
full. They were less than 80% full 10-15 days ago. That is a problem as the
ZFS pool will not be able to heal in the case of a dead HDD. I checked the
snapshots and it appears that deleting them will not get us out of the
hole. A rudimental familiarity with ZFS file system/volume manager is
expected from the Lab members.

https://docs.oracle.com/cd/E26505_01/html/E37384/index.html

It seems that some lab members are making unsubstantiated
assumptions about the file system and infrastructure as a whole instead of
relying on the documentation.

I can expand the ZFS pool hosting those two datasets but not until I am
back to the office.

Best,
Predrag
