Reduce Checkpoint Storage volume

Hi all,

I want to reduce the Checkpoint Storage Volume. I delete all the Schedule Checkpoint and now, I would reduce the Checkpoint Storage Volume.

     Capacity: 2.3To

     Used: 256.0 MB

I believe that the capacity of 2.3 TB is to create schedule checkpoint before copying data on the File System.

Could i delete the different volume affect to the checkpoint Storage Volume ?

[nasadmin@*********]$ nas_volume -info vp168

id          = 168

name        = vp168

acl         = 0

in_use      = True

type        = pool

chunk_size  = 128

volume_set  = v167,v170,v172,v174,v176,v178,v180,v182,v184,v186,v188,v190,v192,v194,v196,v198,v200,v202,v204,v206,v208,v210,v212,v214,v216,v218,v220,v222,v224,v226,v228,v230,

v232,v234,v236,v238,v240,v242,v244,v246,v248,v250,v252,v254,v256,v258,v260,v262,v264,v266,v268,v270,v272,v274,v276,v278,v280,v282,v284,v286,v288,v290,v292,v294,

v296,v298,v300,v302,v304,v306,v308,v310,v312,v314,v316,v318,v320,v322,v324,v326,v328,v330,v332,v334,v336,v338,v340,v342,v344,v346,v348,v350,v352,v354,v356,v358,

v360,v362,v364,v366,v368,v370,v372,v374,v376,v378,v380,v382,v384,v386,v388,v390,v392,v394,v396,v398,v400,v402

disks       = d7

clnt_filesys= vpfs51

Volume description:

[nasadmin@*********]$ nas_volume -info v402

id          = 402

name        = v402

acl         = 0

in_use      = True

type        = meta

volume_set  = s210

disks       = d7

clnt_volume = vp168

First check if you really have no more checkpoints for that file system

Is it replicated? If yes you also have two internal checkpoints used by Replicator

Yes – they are using the same savvol as the manual/scheduled checkpoints

Yes, the file system is replicate to an other VNX. I have two other Checkpoint.

[nasadmin@******** ~]$ fs_ckpt FS-01 -list -all
id    ckpt_name                creation_time           inuse fullmark   total_savvol_used  ckpt_usage_on_savvol
52    root_rep_ckpt_19_52001_1 06/05/2012-23:05:48-CEST  y   90%        0%                 0%
53    root_rep_ckpt_19_52001_2 06/05/2012-23:05:54-CEST  y   90%        0%                 0%
Info 26306752329: The value of ckpt_usage_on_savvol for read-only checkpoints may not be consistent with the total_savvol_used.

id    wckpt_name               inuse fullmark total_savvol_used  base  ckpt_usage_on_savvol

I must stop replication before delete slice volume ?

you must delete replication (which in turn deletes 2 private checkpoints) to reclaim your SAVVOL space,  you can thank Celerra/VNX engineers for this wonderful design.
