→ Applies to: SynetoOS 4.8.5 and above

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2 (optional). Change into Solaris shell (in case you're directed to an unsupported shell)

un sh

Step 3. Get root privileges

sudo su -

Step 4. List snapshots services

synetoid list

EXAMPLE OUTPUT

root@syneto-os4:/var/storage/admin# synetoid  list
online         May_19   svc:/system/filesystem/zfs/auto-snapshot:weekly-flash--datastores--VM1
online         May_19   svc:/system/filesystem/zfs/auto-snapshot:weekly-flash--datastores--VM2
online         13:30:04 svc:/system/filesystem/zfs/auto-snapshot:daily-flash--datastores--VM1
online         14:00:05 svc:/system/filesystem/zfs/auto-snapshot:daily-flash--datastores--VM3
online         15:00:04 svc:/system/filesystem/zfs/auto-snapshot:daily-flash--datastores--VM4

From the list, identify the VM on which the retention policy should be applied.

EXAMPLE

svc:/system/filesystem/zfs/auto-snapshot:weekly-flash--datastores--VM1

Step 5. List the number of snapshots (replace <pool_name> and <vm_name> with the correct information)

zfs list -r -t snapshot <pool_name>/datastores/<vm_name> | wc -l

EXAMPLE OUTPUT

zfs list -r -t snapshot flash/datastores/VM1 | wc -l 
      20

The value 20 represents the total number of snapshots for that datastore.

Step 6. Apply retention (replace <type_protection>, <pool_name> and <vm_name> with the correct information)

synetoid apply-retention svc:/system/filesystem/zfs/auto-snapshot:<type_protection>-<pool_name>--datastores--<vm_name>

EXAMPLE

synetoid apply-retention svc:/system/filesystem/zfs/auto-snapshot:weekly-flash--datastores--VM1

Step 7. Check if the retention policy has been applied (replace <pool_name> and <vm_name> with the correct information)

zfs list -r -t snapshot <pool_name>/datastores/<vm_name> | wc -l

EXAMPLE OUTPUT

root@syneto-os4:/var/storage/admin# zfs list -r -t snapshot flash/datastores/VM1 | wc -l 
      12

The value 12 represents the total number of snapshots for that datastore.
If the number of snapshots has changed from what you recorded in step 5, the procedure was successful.
