GUI

All PIs get their own Quobyte Tenent, within which we create a volume.

1. Login to our Quobyte web console

2. Click Volumes on the left.

3. Verify the PI does not already have a tenant/volume.

4. Tenant -> Create tenant...

   1. Tenant name: {PI-Login-ID}grp

5. Find the new Tenant with the Filter box.

6. Click the three vertical dots next to the PI's tenant name

   1. Edit tenant quota...

      1. Ensure Unit: Binary (Default decimal) is set.

      2. Enter their quota into Any type

   2. Create tenant volume...

      1. Volume name: {PI-Login-ID}grp

      2. Owner user name: {PI-Login-ID}

      3. Owner group name: {PI-Login-ID}grp

      4. POSIX permission mask: 2770

7. Verify the new volume exists:

   1. ls -l /quobyte/{PI-Login-ID}grp

8. Research!

CLI

PREREQUISITE: update qmgmt.sh to use a r/w user.

• Option: create a dedicated script that takes a PI name and quota and does all the work.

  • Show currently allocated quota in dedicated script.

1. SSH to quobyte.hpc.

2. export PI={PI-Login-ID}

3. export PIQuota={Quota-in-TiB}

4. Verify the PI tenant does not already exist.

   1. sudo /opt/hpccf/sbin/qmgmt.sh tenant resolve ${PI}grp

      1. Look for: FATAL: Operation failed due to invalid input: 'No such tenant:

5. Create the tenant: sudo /opt/hpccf/sbin/qmgmt.sh tenant create ${PI}grp

6. Create the volume: sudo /opt/hpccf/sbin/qmgmt.sh volume create "${PI}grp/${PI}grp" ${PI} ${PI}grp 2770

7. Set the quota: sudo /opt/hpccf/sbin/qmgmt.sh quota create TENANT ${PI}grp LOGICAL_DISK_SPACE $(( ${PIQuota} * 1024**4))
