Go to SolutionDelete a Celerra Pool
I want to delete a Celerra pool as it is not being used. This is a "System" pool and not a "User" generated pool. Do I need to shrink the pool first and then delete the pool OR I can go ahead and delete the entire pool itself from GUI and the volumes will also get deleted?
If I shrink a the pool by seleting the volume, will the volumes get deleted and the "nas_disk -l " will show the assossiated disks are unused and then I can delete them will -perm and -unbind option?
The cli manual says, use -delete with -deep option and it recursively deletes each member of the storage pool. Should I use that option to delete the entire pool instead of deleting from GUI?
[nasadmin@canas012 ~]$ nas_pool -size clar_r5_economy
id = 2
name = clar_r5_economy
used_mb = 0
avail_mb = 3102459
total_mb = 3102459
potential_mb = 0
[nasadmin@canas012 ~]$ nas_pool -info clar_r5_economy
id = 2
name = clar_r5_economy
description = CLARiiON RAID5 8plus1
acl = 0
in_use = False
clients =
members = v6053,v6054,v6258,v6262,v6795,v6796,v6797,v9023
default_slice_flag = True
is_user_defined = False
virtually_provisioned= False
disk_type = CLSTD
server_visibility = server_2,server_3,server_4,server_5
volume_profile = clar_r5_economy_vp
is_dynamic = False
is_greedy = False
num_stripe_members = 4
stripe_size = 32768
[nasadmin@canas012 ~]$
Thanks in Advance.

You shouldnt (and hopefully cant) delete system pools
Its actually not necessary – delete every file system using it – then you can use the LUNs/disks in it for something different
The system pools are always there – they are just empty or contain unused elements
Rainer,
As you can see from the command o/p, the pool is empty and there are no filesystems in the pool. I want to getrid of the pool clar_r5_economy (R5, 8+1) and create two RG of R5 4+1 and add it to performance pool. Performance pool is running out of space and I want to add more disks to it. I have a spare disk to add it to 4+1.So you saying I should not/cannot delete this pool?

It is not necessary to delete the pool to free up the drives – you just need to delete and unbind the dvols
From the GUI I did a shrink and selected the all the volumes in the pool and hit OK and when I check CLI the system defined pool was disappeared from the system (automatically) and nas_disk displayed the disks as "n" (not in use) and deleted them using "-perm unbind". thanks for your help.

You cannot delete the System defined pool and even if the pool is just there it will not harm any thing as it does on have any disk in it.
