Hello, Can someone help me why do i see a checkpoint for filesystem null when i look at the properties of Storage pool that was created for a Ckpt. Thank You.

well - if you really want to get into the CLI I would suggest to start with the manuals Managing EMC Celerra Volumes and File Systems with Automatic Volume Management and Managing EMC Celerra Volumes and FIle Systems Manually

just be prepared that the storage CLI commands arent that easy to read

see https://community.emc.com/message/382689#382689 https://community.emc.com/message/383766#383766

start with nas_volume, nas_fs and fs_ckpt

Hello,Please find the attached screenshot.Under the Used by tab i see some checkpoints for filessytem null am concerned that they are eating some space from the storage pool. I appreciate for the help.

I havent seen that before - might just be a glitch with Celerra manager GUI I would suggest to cross check with the CLI or open a service request Rainer

I am seeing this same message now and it appears to be filling up my entire pool.  Was there ever a solution 'Checkpoints for File System null?'

Hi,

this is fixed on NAS code 5.6.48 and above :

From the release notes :

Impact Level

Severity 2

Symptom Desc.

If a PFS and its checkpoints resided on different storage pools, when using WebUI to check the pool

properties page, some checkpoints showed up in the "used by" list as "checkpoint of filesystem null".

Clicking on the hyperlink to display the file system properties resulted in a blank screen.

Fix

Code has been fixed to properly return PFS id for the checkpoints that were taken instead of SavVol id

to ensure proper display of pool properties.

Fixed in version 5.6.48.0
